      To cite the regulations in this volume use title, part and section number. Thus, 46 CFR 90.01-1 refers to title 46, part 90, section 01-1.

      Explanation
      The Code of Federal Regulations is a codification of the general and permanent rules published in the Federal Register by the Executive departments and agencies of the Federal Government. The Code is divided into 50 titles which represent broad areas subject to Federal regulation. Each title is divided into chapters which usually bear the name of the issuing agency. Each chapter is further subdivided into parts covering specific regulatory areas.
      Each volume of the Code is revised at least once each calendar year and issued on a quarterly basis approximately as follows:

        Title 1 through Title 16
        as of January 1
        Title 17 through Title 27
        as of April 1
        Title 28 through Title 41
        as of July 1
        Title 42 through Title 50
        as of October 1

      The appropriate revision date is printed on the cover of each volume.

        LEGAL STATUS
        The contents of the Federal Register are required to be judicially noticed (44 U.S.C. 1507). The Code of Federal Regulations is prima facie evidence of the text of the original documents (44 U.S.C. 1510).

        HOW TO USE THE CODE OF FEDERAL REGULATIONS
        The Code of Federal Regulations is kept up to date by the individual issues of the Federal Register. These two publications must be used together to determine the latest version of any given rule.
        To determine whether a Code volume has been amended since its revision date (in this case, October 1, 2018), consult the “List of CFR Sections Affected (LSA),” which is issued monthly, and the “Cumulative List of Parts Affected,” which appears in the Reader Aids section of the daily Federal Register. These two lists will identify the Federal Register page number of the latest amendment of any given rule.

        EFFECTIVE AND EXPIRATION DATES
        Each volume of the Code contains amendments published in the Federal Register since the last revision of that volume of the Code. Source citations for the regulations are referred to by volume number and page number of the Federal Register and date of publication. Publication dates and effective dates are usually not the same and care must be exercised by the user in determining the actual effective date. In instances where the effective date is beyond the cut-off date for the Code a note has been inserted to reflect the future effective date. In those instances where a regulation published in the Federal Register states a date certain for expiration, an appropriate note will be inserted following the text.

        OMB CONTROL NUMBERS

        The Paperwork Reduction Act of 1980 (Pub. L. 96-511) requires Federal agencies to display an OMB control number with their information collection request. Many agencies have begun publishing numerous OMB control numbers as amendments to existing regulations in the CFR. These OMB numbers are placed as close as possible to the applicable recordkeeping or reporting requirements.

        PAST PROVISIONS OF THE CODE
        Provisions of the Code that are no longer in force and effect as of the revision date stated on the cover of each volume are not carried. Code users may find the text of provisions in effect on any given date in the past by using the appropriate List of CFR Sections Affected (LSA). For the convenience of the reader, a “List of CFR Sections Affected” is published at the end of each CFR volume. For changes to the Code prior to the LSA listings at the end of the volume, consult previous annual editions of the LSA. For changes to the Code prior to 2001, consult the List of CFR Sections Affected compilations, published for 1949-1963, 1964-1972, 1973-1985, and 1986-2000.

        “[RESERVED]” TERMINOLOGY
        The term “[Reserved]” is used as a place holder within the Code of Federal Regulations. An agency may add regulatory information at a “[Reserved]” location at any time. Occasionally “[Reserved]” is used editorially to indicate that a portion of the CFR was left vacant and not accidentally dropped due to a printing or computer error.

        INCORPORATION BY REFERENCE

          What is incorporation by reference? Incorporation by reference was established by statute and allows Federal agencies to meet the requirement to publish regulations in the Federal Register by referring to materials already published elsewhere. For an incorporation to be valid, the Director of the Federal Register must approve it. The legal effect of incorporation by reference is that the material is treated as if it were published in full in the Federal Register (5 U.S.C. 552(a)). This material, like any other properly issued regulation, has the force of law.

          What is a proper incorporation by reference? The Director of the Federal Register will approve an incorporation by reference only when the requirements of 1 CFR part 51 are met. Some of the elements on which approval is based are:
        (a) The incorporation will substantially reduce the volume of material published in the Federal Register.
        (b) The matter incorporated is in fact available to the extent necessary to afford fairness and uniformity in the administrative process.
        (c) The incorporating document is drafted and submitted for publication in accordance with 1 CFR part 51.

          What if the material incorporated by reference cannot be found? If you have any problem locating or obtaining a copy of material listed as an approved incorporation by reference, please contact the agency that issued the regulation containing that incorporation. If, after contacting the agency, you find the material is not available, please notify the Director of the Federal Register, National Archives and Records Administration, 8601 Adelphi Road, College Park, MD 20740-6001, or call 202-741-6010.

        CFR INDEXES AND TABULAR GUIDES

        A subject index to the Code of Federal Regulations is contained in a separate volume, revised annually as of January 1, entitled CFR Index and Finding Aids. This volume contains the Parallel Table of Authorities and Rules. A list of CFR titles, chapters, subchapters, and parts and an alphabetical list of agencies publishing in the CFR are also included in this volume.

        An index to the text of “Title 3—The President” is carried within that volume.
        The Federal Register Index is issued monthly in cumulative form. This index is based on a consolidation of the “Contents” entries in the daily Federal Register.
        A List of CFR Sections Affected (LSA) is published monthly, keyed to the revision dates of the 50 CFR titles.

        REPUBLICATION OF MATERIAL
        There are no restrictions on the republication of material appearing in the Code of Federal Regulations.

        INQUIRIES

              (iii) Between the contiguous states of the United States and the states of Hawaii or Alaska or between the states of Hawaii and Alaska.
              (b) The regulations that apply to a vessel on an “international voyage” in this subchapter do not apply to ships engaged on a voyage solely on the Great Lakes and the St. Lawrence River as far east as a straight line drawn from Cap de Rosiers to West Point, Anticosti Island, the 63d Meridian;
              (c) The Commandant or his authorized representative may exempt any vessel on an international voyage from the requirements of this subchapter if the vessel—
              (1) Makes a single international voyage in exceptional circumstances; and
              (2) Meets safety requirements prescribed for the voyage by the Commandant.
              (d) The Commandant or his authorized representative may exempt any vessel from the construction requirements of this subchapter if the vessel does not proceed more than 20 nautical miles from the nearest land in the course of its voyage.

              Applicability to offshore supply vessels.
              (a) Existing offshore supply vessels as defined by § 90.10-40(b), if they are of 100 GRT (100 GT ITC if GRT is not assigned) as defined in § 125.160 of this chapter or more, are subject to inspection under this subchapter. New offshore supply vessels as defined by § 90.10-40(c), are subject to inspection under subchapter L of this chapter.
              (b) Each offshore supply vessel permitted grandfathering under paragraph (a) of this section must have completed construction and have a Certificate of Inspection by—
              (1) March 16, 1998, if the vessel is of less than 500 GRT (6,000 GT ITC if GRT is not assigned) as defined in § 125.160 of this chapter; or
              (2) August 18, 2016, if the vessel is of at least 6,000 GT ITC (500 GRT if GT ITC is not assigned) as defined in § 125.160 of this chapter.

              § 90.05-25
              Seagoing barge.
              (a) Each seagoing barge, as defined in 46 CFR 90.10-36, is subject to inspection and certification; except that a seagoing barge is exempt from those requirements if it is unmanned for the purposes of operating or navigating the barge, and carries neither a hazardous material as cargo nor a flammable or combustible liquid, including oil, in bulk quantities of 250 barrels or more.

              (b) In applying the laws and regulations to manned seagoing barges, one criterion for invocation of safety standards is the description of seagoing barges by relative size in gross tons. When it is determined by the Commandant that the gross register tonnage for a particular manned seagoing barge, which is attained by exemptions, reductions, or other devices in the basic gross tonnage formulation, will circumvent or be incompatible with the application of specific safety requirements in the regulations in this subchapter for a manned seagoing barge of such physical size, the Commandant shall prescribe the regulations to be made applicable to such seagoing barge. When the Commandant determines that the gross register tonnage is not a valid criterion for the invocation of safety requirements based on relative size, the parties involved will be informed of the determination and of the regulations applicable to such manner seagoing barges, and before being permitted to operate such seagoing barges, compliance therewith shall be required. Endorsements or notations on the seagoing barge's certificate of inspection may be made as appropriate.

              § 91.27-1
              Annual and periodic inspections.
              (a) Annual inspection. Your vessel must undergo an annual inspection within the 3 months before or after each anniversary date, except as required in paragraph (b) of this section.
              (1) You must contact the cognizant Officer in Charge, Marine Inspection to schedule an inspection at a time and place which he or she approves. No written application is required.
              (2) The scope of the annual inspection is the same as the inspection for certification as specified in § 91.25-10 but in less detail unless the cognizant marine inspector finds deficiencies or determines that a major change has occurred since the last inspection. If deficiencies are found or a major change to the vessel has occurred, the marine inspector will conduct an inspection more detailed in scope to ensure that the vessel is in satisfactory condition and fit for the service for which it is intended. If your vessel passes the annual inspection, the marine inspector will endorse your current Certificate of Inspection.
              (3) If the annual inspection reveals deficiencies in your vessel's maintenance, you must make any or all repairs or improvements within the time period specified by the Officer in Charge, Marine Inspection.
              (4) Nothing in this subpart limits the marine inspector from conducting such tests or inspections he or she deems necessary to be assured of the vessel's seaworthiness.
              (b) Periodic inspection. Your vessel must undergo a periodic inspection within 3 months before or after the second or third anniversary of the date of your vessel's Certificate of Inspection. This periodic inspection will take the place of an annual inspection.
              (1) You must contact the cognizant Officer in Charge, Marine Inspection to schedule an inspection at a time and place which he or she approves. No written application is required.

              (2) The scope of the periodic inspection is the same as that for the inspection for certification, as specified in § 91.25-10. The Officer in Charge, Marine Inspection will insure that the vessel is in satisfactory condition and fit for the service for which it is intended. If your vessel passes the periodic inspection, the marine inspector will endorse your current Certificate of Inspection.

              (3) If the periodic inspection reveals deficiencies in your vessel's maintenance, you must make any or all repairs or improvements within the time period specified by the Officer in Charge, Marine Inspection.
              (4) Nothing in this subpart limits the marine inspector from conducting such tests or inspections he or she deems necessary to be assured of the vessel's seaworthiness.

              (a) The field of vision from the navigation bridge, whether the vessel is in a laden or unladen condition, must be such that:
              (1) From the conning position, the view of the sea surface is not obscured forward of the bow by more than the lesser of two ship lengths or 500 meters (1,640 feet) from dead ahead to 10 degrees on either side of the vessel. Within this arc of visibility any blind sector caused by cargo, cargo gear, or other permanent obstruction must not exceed 5 degrees.
              (2) From the conning position, the horizontal field of vision extends over an arc from at least 22.5 degrees abaft the beam on one side of the vessel, through dead ahead, to at least 22.5 degrees abaft the beam on the other side of the vessel. Blind sectors forward of the beam caused by cargo, cargo gear, or other permanent obstruction must not exceed 10 degrees each, nor total more than 20 degrees, including any blind sector within the arc of visibility described in paragraph (a)(1) of this section.
              (3) From each bridge wing, the field of vision extends over an arc from at least 45 degrees on the opposite bow, through dead ahead, to at least dead astern.
              (4) From the main steering position, the field of vision extends over and arc from dead ahead to at least 60 degrees on either side of the vessel.
              (5) From each bridge wing, the respective side of the vessel is visible forward and aft.
              (b) Windows fitted on the navigation bridge must be arranged so that:
              (1) Framing between windows is kept to a minimum and is not installed immediately in front of any work station.

                  1 On vessels of 65 feet (19.8 meters) in length or less, 3/4-inch hose of a good commercial grade together with a commercial garden hose nozzle may be used. The pump may be hand operated and the length of hose must be sufficient to assure coverage of all parts of the vessel.

                  2 A 11/2 inch hose that is 75 feet (22.86 meters) in length with a 5/8-inch nozzle may be used where specified by § 95.10-10(b) of this subpart for interior locations and 50 feet (15.24 meters) of 11/2 inch hose may be used in exterior locations on vessels in other than ocean or coastwise service. For vessels on ocean or coastwise service, two 11/2 inch outlets, each provided with one 11/2 inch hose supplied through a wye connection may be substituted.

              (b) On vessels of 1,000 gross tons or more on an international voyage, each required fire pump, while delivering water thru the fire main system at a pressure corresponding to that required by paragraph (c) of this section, must have a minimum capacity of at least two-thirds of that required for an independent bilge pump. However, in no case may the capacity of each fire pump be less than that otherwise required by this section.
              (c) Each pump must be capable of delivering water simultaneously from the two highest outlets at a Pitot tube pressure of approximately 50 p.s.i. Where 11/2-inch hose is permitted in lieu of 21/2-inch hose by footnote 2 of Table 95.10-5(a), the pump capacity must be determined on the same basis as if 21/2-inch hose had been permitted. Where 3/4-inch hose is permitted by Table 95.10-5(a), the Pitot tube pressure need be only 35 p.s.i.
              (d) Fire pumps must be fitted on the discharge side with relief valves set to relieve at 25 p.s.i. in excess of the pressure necessary to maintain the requirements of paragraph (c) of this section or 125 p.s.i., whichever is greater. Relief valves may be omitted if the pumps, operating under shut-off conditions, are not capable of developing a pressure exceeding this amount.
              (e) Fire pumps must be fitted with a pressure gage on the discharge side of the pumps.
              (f) Fire pumps may be used for other purposes provided at least one of the required pumps is kept available for use on the fire system at all times. In no case shall a pump having connection to an oil line be used as a fire pump. Branch lines connected to the fire main for purposes other than fire and deck wash shall be so arranged that adequate water can be made continuously available for firefighting purposes.
              (g) The total area of the pipes leading from a pump must not be less than the discharge area of the pump.
              (h) On vessels with oil fired boilers, either main or auxiliary, or with internal combustion propulsion machinery, where two fire pumps are required, they shall be located in separate spaces, and the arrangement of pumps, sea connections, and sources of power shall be such as to insure that a fire in any one space will not put all of the fire pumps out of operation. However, when it is shown to the satisfaction of the Commandant that it is unreasonable or impracticable to meet this requirement due to the size or arrangement of the vessel, or for other reasons, the installation of a total flooding fixed fire extinguishing or clean agent system may be accepted as an alternate method of extinguishing any fire that could affect the powering and operation of at least one of the required fire pumps.

              § 95.10-10
              Fire hydrants and hose.
              (a) The size of fire hydrants, hose, and nozzles and the length of hose required must be as noted in Table 95.10-5(a).

              (b) Instead of the 21/2-in hose and hydrants specified in Table 95.10-5(a) of this subpart, on vessels of more than 1,500 gross tons:

              (1) The hydrants in interior locations may have wye connections for 11/2-in hoses. In these cases, the hose must be 75 ft in length, and only one hose is required at each fire station; however, if all such stations can be satisfactorily served with 50-ft lengths, a 50-ft hose may be used; and
              (2) The hydrants for exterior locations may substitute two 11/2 in outlets, each with a 11/2-in hose, supplied through a wye connection.
              (c) On vessels of 500 gross tons or more there must be at least one shore connection to the fire main available to each side of the vessel in an accessible location. Suitable cut-out valves and check valves must be provided. Suitable adapters also must be provided for furnishing the vessel's shore connections with couplings mating those on the shore fire lines. Vessels of 500 gross tons or more on an international voyage, must be provided with at least one international shore connection complying with ASTM F 1121 (incorporated by reference, see § 95.01-2). Facilities must be available enabling an international connection to be used on either side of the vessel.
              (d) Fire hydrants must be of sufficient number and so located that any part of the vessel, other than main machinery spaces, accessible to persons on board while the vessel is being navigated and all cargo holds may be reached with at least 2 streams of water from separate outlets, at least one of which must be from a single length of hose. In main machinery spaces, all portions of such spaces must be capable of being reached by at least 2 streams of water, each of which must be from a single length of hose from separate outlets; however, this requirement need not apply to shaft alleys containing no assigned space for the stowage of combustibles. Fire hydrants must be numbered as required by § 97.37-15 of this subchapter.
              (e) All parts of the fire main located on exposed decks must either be protected against freezing or be fitted with cut-out valves and drain valves so that the entire exposed parts of such piping may be shut off and drained in freezing weather. Except when closed to prevent freezing, such valves must be sealed open.
              (f) The outlet at the fire hydrant must be limited to any position from the horizontal to the vertical pointing downward, so that the hose will lead horizontally or downward to minimize the possibility of kinking.
              (g) Each fire hydrant must have at least one length of firehose, a spanner wrench, and a hose rack or other device for stowing the hose.
              (h) Firehose must be connected to the outlets at all times. However, on open decks where no protection is afforded to the hose in heavy weather, or where the hose may be liable to damage from the handling of cargo, the hose may be temporarily removed from the hydrant and stowed in an accessible nearby location.
              (i) Each firehose on each hydrant must have a combination solid stream and water spray firehose nozzle approved under subpart 162.027 of this chapter. Firehose nozzles previously approved under subpart 162.027 of this chapter may be retained so long as they are maintained in good condition to the satisfaction of the Officer in Charge, Marine Inspection.
              (j) In each propulsion machinery space containing an oil fired boiler, internal combustion machinery, or oil fuel unit on a vessel on an international voyage or of 1000 gross tons or more, each firehose having a combination nozzle previously approved under subpart 162.027 of this chapter must have a low-velocity water spray applicator that is also previously approved under subpart 162.027 of this chapter. The length of the applicator must be less than 1.8 meters (6 feet).
              (k) Fixed brackets, hooks, or other means for stowing an applicator must be next to each fire hydrant that has an applicator under paragraph (j) of this section.
              (l) Firehose must not be used for any other purpose than fire extinguishing, drills, and testing.
              (m) Fire hydrants, nozzles, and other fittings must have threads to accommodate the hose connections noted in paragraph (l) of this section.
              (n) Firehose and couplings must be as follows:

              (1) Fire station hydrant connections must be brass, bronze, or other equivalent metal. Couplings must either:

              (i) Use National Standard firehose coupling threads for the 11/2 inch (38 millimeter) and 21/2 inch (64 millimeter) hose sizes, i.e., 9 threads per inch for 11/2 inch hose, and 71/2 threads per inch for 21/2 inch hose; or
              (ii) Be a uniform design for each hose diameter throughout the vessel.
              (2) Where 19 millimeters (3/4 inch) hose is permitted by table 95.10-5(a), the hose and couplings must be of good commercial grade.
              (3) Each section of firehose must be lined commercial firehose that conforms to Underwriters' Laboratories, Inc. Standard 19 or Federal Specification ZZ-H-451E. Hose that bears the label of Underwriters' Laboratories, Inc. as lined firehose is accepted as conforming to this requirement.

              § 95.15-1
              Application.
              (a) Where a carbon dioxide extinguishing system is installed, the provisions of this subpart, with the exception of § 95.15-90, shall apply to all installations contracted for on or after November 19, 1952. Installations contracted for prior to November 19, 1952, shall meet the requirements of § 95.15-90.
              (b) The requirements of this subpart are based on a “high pressure system,” i.e., one in which the carbon dioxide is stored in liquid form at atmospheric temperature. Details for “low pressure systems,” i. e., those in which the carbon dioxide is stored in liquid form at a continuously controlled low temperature, may be specifically approved by the Commandant where it is demonstrated that a comparable degree of safety and fire extinguishing ability is achieved.

              § 95.15-5
              Quantity, pipe sizes, and discharge rates.
              (a) General. The amount of carbon dioxide required for each space shall be as determined by paragraphs (b) through (d) of this section.
              (b) Total available supply. A separate supply of carbon dioxide need not be provided for each space protected. The total available supply shall be at least sufficient for the space requiring the greatest amount.
              (c) Cargo spaces. (1) The number of pounds of carbon dioxide required for each space shall be equal to the gross volume of the space in cubic feet divided by 30.
              (2) Although separate piping shall be led to each cargo hold and 'tween deck, for the purpose of determining the amount of carbon dioxide required, a cargo compartment will be considered as the space between watertight or firescreen bulkheads and from the tank top or lowest deck to the deck head of the uppermost space on which cargo may be carried. If a trunk extends beyond such deck, the trunk volume shall be included. Tonnage openings shall be considered as sealed for this purpose.
              (3) Branch lines to the various cargo holds and 'tween decks shall not be less than 3/4-inch standard pipe size.
              (4) No specific discharge rate need be applied to such systems.
              (d) Machinery spaces, paint lockers, tanks, and similar spaces. (1) Except as provided in paragraph (d)(3) of this section, the number of pounds of carbon dioxide required for each space shall be equal to the gross volume of the space divided by the appropriate factor noted in Table 95.15-5(d)(1). If fuel can drain from the compartment being protected to an adjacent compartment, or if the compartments are not entirely separate, the requirements for both compartments shall be used to determine the amount of carbon dioxide to be provided. The carbon dioxide shall be arranged to discharge into both such compartments simultaneously.

For installations contracted for on or after October 1, 1959, “normal machinery casing” and “material reduction in casing area” shall be defined as follows:
              (i) By “normal machinery casing” shall be meant a casing the area of which is not more than 40 percent of the maximum area of the machinery space.
              (ii) By “material reduction in casing area” shall be meant a reduction to at least 40 percent of the casing area.
              (3) For vessels on an international voyage contracted for on or after May 26, 1965, the amount of carbon dioxide required for a space containing propulsion boilers or internal combustion propulsion machinery shall be as given by paragraphs (d) (1) and (2) of this section or by dividing the entire volume, including the casing, by a factor of 25, whichever is the larger.
              (4) Branch lines to the various spaces shall be as noted in Table 95.15-5(d)(4).

              (5) Distribution piping within the space shall be proportioned from the supply line to give proper distribution to the outlets without throttling.
              (6) The number, type, and location of discharge outlets shall be such as to give a uniform distribution throughout the space.
              (7) The total area of all discharge outlets shall not exceed 85 percent nor be less than 35 percent of the nominal cylinder outlet area or the area of the supply pipe, whichever is smaller. The nominal cylinder outlet area in square inches shall be determined by multiplying the factor 0.0022 by the number of pounds of carbon dioxide required, except that in no case shall this outlet area be less than 0.110 square inches.
              (8) The discharge of at least 85 percent of the required amount of carbon dioxide shall be complete within 2 minutes.
              (e) Spaces specially suitable for vehicles. (1) The number of pounds of carbon dioxide required must be equal to the gross volume of the largest space which is capable of being sealed divided by 22. In no case, however, may the quantity be less than that required by paragraph (c)(2) of this section.
              (2) The discharge of two thirds of the required quantity of carbon dioxide must be completed within 10 minutes. Any faster discharge rate is also acceptable.
              (3) Except as noted in paragraphs (e) (1) and (2) of this section, the requirements of paragraph (d) of this section shall apply.

              Controls.
              (a) Except as noted in § 95.15-20(b) all controls and valves for the operation of the system shall be outside the space protected, and shall not be located in any space that might be cut off or made inaccessible in the event of fire in any of the spaces protected.
              (b) If the same cylinders are used to protect more than one hazard, a manifold with normally closed stop valves shall be used to direct the carbon dioxide into the proper space. If cylinders are used to protect only one hazard, a normally closed stop valve shall be installed between the cylinders and the hazard except for systems of the type indicated in § 95.15-5(d) which contain not more than 300 pounds of carbon dioxide.

              (c) Distribution piping to the various cargo spaces shall be controlled from not more than two stations. One of the stations controlling the system for the main machinery space shall be located as convenient as practicable to one of the main escapes from the space. All control stations and the individual valves and controls shall be marked as required by §§ 97.37-10 and 97.37-13 of this subchapter.
              (d) Systems of the type indicated in § 95.15-5(d) shall be actuated by one control operating the valve to the space and a separate control releasing at least the required amount of carbon dioxide. These two controls shall be located in a box or other enclosure clearly identified for the particular space. Those systems installed without a stop valve shall be operated by one control releasing at least the required amount of carbon dioxide.
              (e) Where provisions are made for the simultaneous release of a given amount of carbon dioxide by operation of a remote control, provisions shall also be made for manual control at the cylinders. Where gas pressure from pilot cylinders is used as a means for releasing the remaining cylinders, not less than two pilot cylinders shall be used for systems consisting of more than two cylinders. Each of the pilot cylinders shall be capable of manual control at the cylinder, but the remaining cylinders need not be capable of individual manual control.
              (f) Systems of the type indicated in § 95.15-5(d), other than systems for tanks, which are of more than 300 pounds of carbon dioxide, shall be fitted with an approved delayed discharge so arranged that the alarm will be sounded for at least 20 seconds before the carbon dioxide is released into the space. Such systems of not more than 300 pounds of carbon dioxide shall also have a similar delayed discharge, except for those systems for tanks and for spaces which have a suitable horizontal escape. This paragraph shall be applicable only to systems installed on or after July 1, 1957.

              Bulk means a quantity of a commodity carried as a liquid cargo or liquid-cargo residue, without mark or count, in an integral, fixed, or portable tank. It does not include liquid cargo packaged in a portable tank that is loaded and discharged from a vessel with the contents intact.

              Cargo means a combustible liquid or flammable liquid transported in commerce by a commercial fish processing vessel for delivery to a recipient inside or outside the fishing industry. It does not include combustible liquids or flammable liquids carried in a tank for use only by machinery and boats carried aboard the processing vessel, or for use only by vessels that are directly supporting the processing vessel's primary operations.

              Certificate of compliance means the document issued and displayed in accordance with § 105.10.

              Combustible liquid means any liquid having a flashpoint above 80 °F (as determined from an open cup tester, as used for testing of burning oils). A Grade D combustible liquid is one having a flashpoint above 80 °F and below 150 °F. A Grade E combustible liquid is one having a flashpoint of 150 °F or above.

              Commercial fish processing vessel means a self-propelled manned vessel that commercially prepares fish or fish products other than by gutting, decapitating, gilling, skinning, shucking, icing, freezing, or brine chilling.

              Dispensing means the unloading of any quantity of flammable or combustible liquids in bulk.

              Dispensing tank means any tank from which a quantity of a flammable or combustible liquid is filled or emptied onboard the vessel by means of pumping, gravitation, or displacement.

              Examination means a careful and critical assessment of the vessel and its appurtenances carried out by an authorized examiner or an organization designated by the Commandant, U.S. Coast Guard. This includes, where necessary, a visual assessment of the vessel's hull, structures, electrical systems, and machinery, supplemented by other means such as measurement and/or nondestructive testing.

              Flammable liquid means any liquid that gives off flammable vapors (as determined by flashpoint from an open cup tester, as used for testing of burning oils) at or below 80 °F. Flammable liquids are referred to by grades as follows:
            (1) Grade A. Any flammable liquid having a Reid vapor pressure of 14 pounds or more, as measured in accordance with ASTM D 323 (incorporated by reference, see § 105.3).
            (2) Grade B. Any flammable liquid having a Reid vapor pressure of less than 14 pounds and more than 81/2 pounds, as measured in accordance with ASTM D 323.
            (3) Grade C. Any flammable liquid having a Reid vapor pressure of 81/2 pounds or less and a flashpoint of 80 °F or below, as measured in accordance with ASTM D 323.

              Fuel tank means a tank other than a dispensing tank used to transport flammable or combustible liquid for the purpose of supplying fuel for propulsion of the vessel to which it is attached.

              Limited quantities means not more than 20 percent of a vessel's deadweight tonnage as applied to bulk liquid cargoes or carried in permanent or temporary tanks.

              New vessel means a vessel whose construction is contracted for on or after May 31, 1976.

              Pressure vacuum relief valve means any device or assembly of a mechanical, liquid, weight, or other type used for the automatic regulation of pressure or vacuum in enclosed places.

            § 105.10
            Vessel examination.
            (a) Each examination referred to in this section must be conducted by the Coast Guard to determine whether the examined vessel is in substantial compliance with this part. An examination may include any test or verification that the examiner deems necessary for determining the vessel's safety and seaworthiness.

            (1) The owner or operator of each vessel subject to this part must apply, using Form CG-3752, available at http://www.uscg.mil/forms/cg/cg_3752.pdf, to the cognizant Officer in Charge, Marine Inspection, for the vessel to be examined in accordance with paragraph (b) of this section. In applying for a vessel's initial examination under this section, the application must be accompanied by a plan or sketch of each cargo tank and piping system for filling and dispensing bulk flammable or combustible cargoes, and a brief description of those systems, including their dimensions and materials used. If cargo tanks are located in enclosed compartments or below decks, the plans or sketches must show the ventilation system. Plans or sketches need not be submitted if the cargo tanks and piping systems have previously been accepted by the Coast Guard.

            (2) Each vessel must be examined before its first use in loading, transporting, or dispensing combustible or flammable liquids in bulk, and at least annually thereafter if the vessel carries such liquids in temporarily installed cargo tanks or containers, or at least biennially thereafter if the vessel carries such liquids in permanently installed cargo tanks.
            (3) A vessel that is laid up, dismantled, or out of commission is exempt from the requirements of this section.
            (b) After examining a vessel and finding it to be in substantial compliance with this part, the Coast Guard will issue, and the vessel's owner or operator must display on board, a certificate of compliance that describes the amounts of bulk liquid flammable or combustible cargoes that the vessel may carry, the number of crewmembers required to hold merchant mariner credentials and tankerman endorsements in accordance with 46 U.S.C. 8304 and 46 CFR part 13, and any conditions applicable to the carriage or dispensation of those cargoes. Each certificate of compliance is valid for not more than 2 years or until suspended or revoked. A letter of compliance may be issued as an alternative to a certificate of compliance.

            § 105.11
            Prohibitions.
            Each vessel to which this part applies is prohibited from transporting Grade A flammable liquids in bulk, or carrying bulk flammable or combustible liquids in portable or temporarily installed dispensing tanks or containers that are either below deck or in closed compartments on or above deck.

            Subpart D—Certificates Under International Convention for Safety of Life at Sea, 1974

              § 107.401
              Purpose and definition.
              (a) The International Convention for Safety of Life at Sea, 1974, requires one or more of the certificates described in this subpart to be carried on self-propelled vessels of 500 gross tons or over engaged in international voyages. This subpart prescribes rules for the issuance of these certificates to mobile offshore drilling units.
              (b) “International voyage” has the same meaning as stated in Regulation 2(d) of part A, chapter I in the International Convention for Safety of Life at Sea, 1974. (SOLAS 74), which is: “a voyage from a country to which the present Convention applies to a port outside such country, or conversely. The Coast Guard has interpreted this definition to include the following:
              (1) A voyage from a country to which SOLAS 1974 applies, to a port outside that country or the reverse;
              (2) A voyage from any territory, including the Commonwealth of Puerto Rico, all possessions of the United States, and all lands held by the United States under a protectorate or mandate, whose international relations are the responsibility of a contracting SOLAS 74 government, or which is administered by the United Nations, to a port outside that territory or the reverse;

              The Coast Guard has interpreted this definition to not include a “Great Lakes voyage” which means a voyage solely on the Great Lakes of North America and the St. Lawrence River west of a straight line drawn from Capedes Rosiers to West Point, Anticosti Island and, on the north side of Anticosti Island, the 63rd Meridian.
              [CGD 73-251, 43 FR 56802, Dec. 4, 1978, as amended by CGD 90-008, 55 FR 30662, July 26, 1990]

              § 107.405
              Safety Equipment Certificate.
              (a) A self-propelled unit of at least 500 gross tons that engages in international voyages is issued a safety equipment certificate if the inspector issues it a certificate of inspection under § 107.211 or § 107.215 and it meets chapter 3 of the International Convention for Safety of Life at Sea, 1974.
              (b) A Safety Equipment Certificate expires 60 months after the date of issue.
              [CGD 73-251, 43 FR 56802, Dec. 4, 1978, as amended by CGD 90-008, 55 FR 30662, July 26, 1990; USCG-1999-4976, 65 FR 6504, Feb. 9, 2000]

              Safety Construction Certificate.
              (a) Application for a Safety Construction Certificate is made by indicating in the space provided on the Application for Inspection Form CG-3752 whether the American Bureau of Shipping or the Coast Guard is to issue the certificate.
              (b) The American Bureau of Shipping or the Coast Guard may issue a self-propelled unit of at least 500 gross tons that engages on international voyages a Safety Construction Certificate if the unit meets the requirements in Regulation 12 (a)(ii), Chapter I of the International Convention for Safety of Life at Sea, 1974.
              (c) A Safety Construction Certificate expires 60 months after the date of issue.
              (d) If a unit fails to meet the requirements in Regulation 12(a)(ii), the Coast Guard may—
              (1) Suspend an unexpired Safety Construction Certificate; and
              (2) Revoke an unexpired Safety Construction Certificate.

              § 107.413
              Exemption certificate.
              (a) An owner or operator of a unit may request an exemption from the requirements of the International Convention for Safety of Life at Sea, 1974 (SOLAS 74) by writing to the appropriate OCMI.

              (b) The Commandant (CG-CVC) may exempt a self-propelled unit of at least 500 gross tons on an international voyage from any of the requirements in the International Convention for Safety of Life at Sea, 1974 (SOLAS 74) if the unit meets the conditions of Regulation 4 of Part A, Chapter I, of SOLAS 74 which states the following:

                a. A ship which is not normally engaged on international voyages but which, in exceptional circumstances, is required to undertake a single international voyage may be exempted by the Administration from any of the requirements of the present Regulations provided that it complies with safety requirements which are adequate in the opinion of the Administration for the voyage which is to be undertaken by the ship.
                b. The Administration may exempt any ship which embodies features of a novel kind from any of the provisions of Chapters II-1, II-2, III and IV of these Regulations the application of which might seriously impede research into the development of such features and their incorporation in ships engaged on international voyages. Any such ship shall, however, comply with safety requirements which, in the opinion of that Administration, are adequate for the service for which it is intended and are such as to ensure the overall safety of the ship and which are acceptable to the Governments of the States to be visited by the ship. The Administration which allows any such exemption shall communicate to the Organization particulars of same and the reasons therefor which the Organization shall circulate to the Contracting Governments for their information.

              (c) The Commandant (CG-CVC) may exempt a self-propelled unit of at least 500 gross tons on an international voyage from the requirements of Chapter III (Lifesaving Appliances, &C.) of SOLAS 74 if the unit meets the conditions of Regulation 2 of chapter III which states in part:

                The Administration may, if it considers that the sheltered nature and conditions of the voyage are such as to render the application of any specific requirements of this chapter unreasonable or unnecessary, exempt from those requirements individual ships or classes of ships which, in the course of their voyage, do not proceed more than 20 miles from the nearest land.

              (d) The Commandant (CG-CVC) may exempt a unit from the requirements of Chapters II-1 (Construction—Subdivision and stability, machinery and electrical installations) or II-2 (Construction—Fire protection, fire detection and fire extinction) of SOLAS 74 if the unit meets the conditions of Regulation 1-4 of Part A Chapter II-1 or Regulation 1-4.1 of Part A Chapter II-2, respectively, of SOLAS 74 which state the following: The Administration of a State may, if it considers that the sheltered nature and conditions of the voyage are such as to render the application of any specific requirements of this chapter unreasonable or unnecessary, exempt from those requirements individual ships or classes of ships entitled to fly the flag of the State which, in the course of their voyage, do not proceed more than 20 miles from the nearest land.
              (e) An Exemption Certificate is in force for the period of validity of the certificate to which it refers.

If a fire pump is used in a system other than the fire main system, except for branch lines connected to the fire main for deck washing, each pipe connecting the other system must be connected to the pump discharge through a shut off valve at a manifold near the pump. If the fire pump exceeds the pressure in § 108.417(a), the pipe leading from the discharge manifold to other portions of the fire main system must have a reducing station and a pressure gauge in addition to the pressure gauge required by paragraph (b) of this section.
                (d) If a fire pump has a reducing station, the relief valve required by paragraph (a) of this section for the pump and the additional pressure gauge required in paragraph (c) of this section must not be located on the discharge side of the reducing station.
                (e) An oil line must not be connected to a fire pump.

              (ii) Immersion suits approved under approval series 160.171 of the appropriate size for each person on board, which count toward meeting the requirements of paragraph (c)(1)(i) of this section; and

              (iii) In addition to the immersion suits required under paragraph (c)(1)(ii) of this section, each watch station, work station, and industrial work site must have enough immersion suits to equal the number of persons normally on watch in, or assigned to, the station or site at one time. However, an immersion suit is not required at a station or site for a person whose cabin or berthing area (and the immersion suits stowed in that location) is readily accessible to the station or site.
              (2) Attachments and fittings. Immersion suits or anti-exposure suits must have the following attachments and fittings:
              (i) Each immersion suit or anti-exposure suit must have a lifejacket light approved under approval series 161.112 securely attached to the front shoulder area of the immersion suit or anti-exposure suit. On a unit not in international service, a light approved under approval series 161.012 may be used. However, lifejacket lights bearing Coast Guard approval number 161.012/2/1 are not permitted on units certificated to operate on waters where water temperature may drop below 10 °C (50 °F).
              (ii) Each immersion suit or anti-exposure suit must have a whistle firmly secured by a cord to the immersion suit or anti-exposure suit.

              Pt. 109, App. A
              Appendix A to Part 109—Navigation and Vessel Inspection Circular No. 4-78—Inspection and Certification of Existing Mobile Offshore Drilling Units
              1. Purpose. To promulgate instructions for the inspection and certification of existing mobile offshore drilling units. This NVIC is also being published as appendix A of 46 CFR Subchapter IA.
              2. Background. Mobile Offshore Drilling Units are recognized internationally through the Intergovernmental Maritime Consultative Organization as being a “special purpose ship” designed and operated to carry out an industrial function at sea. Contemporary U.S. Vessel regulations in Title 46 CFR do not adequately cover the safety considerations which are unique to the hull and structural designs, industrial equipment and operating procedures incorporated in drilling vessels. To provide appropriate and adequate standards, the Coast Guard with the assistance of the National Offshore Operations Advisory Committee, and following the provisions of the Administrative Procedures Act, developed Subchapter IA, Regulations for Mobile Offshore Drilling Units, 46 CFR Parts 107-109 and amendments to 46 CFR Subchapters “F”, Marine Engineering Regulations, and “J”, Electrical Engineering Regulations. These regulations, published in Federal Register (43 FR 56788 December 4, 1978) will apply to all units contracted for on or after the effective date of the regulations.
              3. Discussion. a. This NVIC elaborates the “grandfather provisions” of 46 CFR 107.211 and 107.215 in applying Subchapter IA to the approximately 150 existing ocean-going U.S. flag mobile offshore drilling units. “Existing” Mobile Offshore Drilling Units are those vessels which have been contracted for before the effective date of the regulations including:
              (1) Units in Service.
              (2) Units under construction.
              (3) Units contracted for which are to be constructed and delivered prior to January 1, 1981.
              b. Existing uncertificated mobile drilling units of which there are approximately 92 of the bottom bearing configuration, i.e., jack-up and submersible types, have not previously been required to comply with vessel inspection regulations. Some units have met the load line requirements of Subchapter “E” for International Voyages. Many of the older units are not classed by a classification society. Bottom bearing units operating on the Outer Continental Shelf of United States have been required to meet the safety requirements of 33 CFR Subchapter “N” as artificial islands. On January 3, 1979, existing bottom bearing units are subject to the “grandfather provisions” in § 107.211(c) of Subchapter IA.
              c. Existing certificated mobile offshore drilling units, for the purposes of this NVIC, are column-stabilized and ship-shape types of which approximately 58 are currently certificated, or have made application for an original Certificate of Inspection or intend to make application for an original inspection for certification under 46 CFR Subchapter “I” on the basis of the unit being contracted for prior to the effective date of the new regulations. These units may continue to meet the structural, equipment, material and arrangement standards which were applicable to the hull, engineering, electrical and industrial systems when the units were contracted for. In addition they must meet the provisions of d.(1), d.(4)(d), d.(7)(b), d.(8), d.(9), d.(10)(b), d.(11) and d.(12) of paragraph 3 of this NVC in accordance with § 107.215(c)(2) of Subchapter IA.
              d. Inspection Provisions for Existing Uncertificated Units. The intent of the “grandfather” provisions of this NVIC for existing uncertificated units is to ascertain through inspection that the material condition of the unit and its equipment meet reasonable levels of safety. To this end, the following determinations will be made:
              • The design, construction and arrangements of the hull, machinery electrical and industrial systems do not reveal manifestly unsafe aspects.
              • There is no excessive deterioration of the hull structure or equipment foundations.
              • There are no intrinsic fire or explosion hazards.
              • There are no personnel hazards such as unguarded moving machinery, potential electrical shock conditions or lack of handrails.
              • The unit is seaworthy and exhibits satisfactory stability.
              (1) General. (a) Repairs and minor alterations to hull structure or equipment may be made to the same standards as the original installation. However, new installations or major alterations which affect vessel or personnel safety shall meet the applicable standards of Subchapter IA.

              (b) Existing items of safety equipment not meeting the applicable specifications or requirements set forth in Subchapter IA may be continued in service as long as they are maintained in good working order to the satisfaction of the OCMI. Such safety equipment and installations requiring extensive repairs shall be replaced and shall meet the applicable specifications and requirements of Subchapter IA.
              (c) The OCMI has discretion to accept alternatives or equivalents which meet the established standards, and to give special consideration to departures from the regulations when it can be shown that special circumstances warrant such departures.
              (2) Plan Submittal. (a) For units not classed by the American Bureau of Shipping or other recognized classification society, (see 46 CFR 108.109) the OCMI must have sufficient plans and information submitted to him which will describe such things as the unit's size, construction, configuration, arrangement of tanks, decks and spaces; and the machinery and electrical installation. In addition, the OCMI may require submittal of any additional data he considers necessary in order to proceed with the original inspections.
              (b) For units classed by the American Bureau of Shipping or other recognized classification society, the plans and information described in Subchapter IA § 107.305 (a), (b), (v), and (ii) and a general description of the machinery and electrical installation shall be submitted to the OCMI for information. The OCMI may accept continued classification as proof of structural, mechanical, and electrical sufficiency. However, the OCMI may require additional plans and information if necessary.
              (3) Hull Structure. (a) No structural changes will be required unless manifestly unsafe conditions exist.
              (b) Existing uncertificated units must be drydocked or have a special examination in lieu of drydocking as required by 46 CFR, 107-261.
              (c) Achievement of one compartment subdivision is not required where extensive modification of the original design would be necessary; however, watertight integrity of the hull and structural boundaries must be maintained. Bulkheads and decks designed to be watertight must be maintained as such where they are penetrated by pipes, electrical cable, reach rods, ventilation systems, etc.
              (4) Stability. (a) The stability of each existing unit will be reviewed by the Coast Guard. The plans indicated in 46 CFR Subchapter IA § 107.305(q) through (u-l) must be submitted to the cognizant OCMI or Merchant Marine Technical Office.
              (b) Lightship data from a Coast Guard witnessed and approved stability test is required for each existing, uncertificated unit. Alternatively other evidence of lightship values will be considered on a case by case basis.
              (c) In general, compliance with the intact stability standards of 46 CFR Subchapter IA, §§ 108.303 through 108.309 is required. Where existing units were designed to a lesser standard of stability than that specified in §§ 108.303 through 108.309, some relaxation based on proven past performance may be granted at the discretion of the OCMI and limiting conditions, if any, set forth in the operating manual. In no case will the minimum wind speed for adequate stability be reduced below 50 knots.
              (d) An operating manual shall be prepared for each unit. Each operating manual must contain the information indicated in 46 CFR Subchapter IA, § 109.121(d) and be submitted to the cognizant OCMI or Merchant Marine Technical Office for review.
              (5) Load Line. (a) All units are required to obtain and maintain a valid Load Line Certificate. The structure and stability of the unit must be proven adequate for the voyages and areas of operation intended.
              (b) The American Bureau of Shipping or other recognized classification society will issue Load Line Certificates and conduct initial and annual load line surveys. Coast Guard and the American Bureau of Shipping inspections may be conducted simultaneously, but it is the owner's responsibility to arrange coordinated inspection schedules.
              (c) The structural review conducted by the American Bureau of Shipping or other recognized classification society for load line assignment may be accepted by the Coast Guard as proof of structural adequacy of the hull.
              (d) The stability review must be completed prior to issuance of a Load Line Certificate. The Coast Guard will inform the American Bureau of Shipping or other recognized classification society of the results of the stability review, and will indicate any stability limitations to be placed on the Load Line Certificate.
              (e) Freeboard calculations for self-elevating units with barge type hulls will be made in accordance with 46 CFR, Part 42. The bow height requirements of 46 CFR 42.20-70 may be relaxed to approximately 33% of the normal requirement for barge shapes moving at speeds less than 6 knots. No relaxation of the addition to freeboard for deficiency in sheer is allowed. The freeboard for units other than self-elevating units with barge type hulls will be based upon compliance with the intact and damage stability standards applicable at the time the unit was contracted for.
              (f) All units delivered after the date of this NVIC regardless of contract date, must obtain a Load Line Certificate as soon as operationally feasible.
              (6) Route and Operating Area Limitations. (a) Units classed by the American Bureau of Shipping or other recognized classification society for ocean service generally will be certificated by the Coast Guard for ocean routes.

              (b) Unclassed units which have proven structural and stability adequacy by continued safe operation in a specific geographic area, such as the Gulf of Mexico, will be limited by the Certificate of Inspection and Load Line Certificate to that area. To qualify for an unlimited oceans route, such a unit must be reviewed for adequacy of the structure and stability by the Coast Guard and meet the Load Line requirements of d. (5) above.
              (c) Any unit which intends to move or operate outside the geographical area indicated on the Certificate of Inspection must receive prior approval from the OCMI.
              (7) Fire Protection. (a) Structural fire protection. All units must meet the provisions of § 108.123, Insulation of Combustible Materials and § 108.127, Storage Lockers for Combustibles. All existing interior stairways which are open at each end must be enclosed at one level. On units where wood was utilized in the construction of accommodation spaces, each space must be equipped with a smoke or heat detector either battery powered or operating on the AC power supply. All detectors must have the Underwriters Laboratories, Inc., label (UL) or the Factory Mutual Laboratories (FM) label.
              (b) Fire Extinguishing Systems. Systems and equipment must be provided which will meet or be equivalent to the applicable specifications and provisions required by Subchapter IA. Installed fire extinguishing systems, which provide equivalent or greater protection than systems required by Subpart E, Subchapter IA may be continued in use as long as they are in good material condition and will function as designed. Where practicable, existing washdown systems may be utilized as the firemain. Where wood was utilized in the construction of accommodation spaces, the applicable requirements of 46 CFR Subchapter IA, Table 108.495(a) should be doubled.
              (8) Lifesaving Equipment. (a) Each unit must have lifesaving equipment (lifeboats and davit launched liferafts) for 200 percent of the total persons allowed on board. Except for submersible type units, the installation of lifeboats for 100 percent of the persons (on board) is required in accordance with 46 CFR 108.503 of Subchapter IA. Consideration will be given to those units where existing arrangement and structure do not provide sufficient room for installation of the lifeboats or where the added weight of the lifeboats, davits and winches will materially reduce the variable load capacity of the unit. In such cases, davit launched inflatable liferafts with a combined personnel capacity of the required lifeboats, and a rescue boat approved by the OCMI may be acceptable equivalents. Submersible type units may substitute Coast Guard approved throw over type inflatable liferafts and an approved rescue boat for the required lifeboats.
              (b) For the second part of the total 200 percent primary lifesaving requirement, lifeboats installed in accordance with 33 CFR, Subchapter “N” Part 144 or Coast Guard approved life floats may be retained as provided for in 3.d(1)(b) of this Circular. They will be considered collectively with the Coast Guard approved liferafts for calculating the amount of equipment to provide for 100 percent of personnel on board.
              (c) Adequate access to all lifesaving equipment must be provided.
              (9) Cranes. (a) Plan approval will not normally be required of any crane which conforms to the specifications of the manufacturer as originally installed. A rated load test as described in § 107.260 of Subchapter IA will be required unless the crane has been load tested while under certification by an approved certifying authority as provided for in 46 CFR 107.258. Prior to the rated load test, the crane should be identified by manufacturer and model number to determine that the correct load rating chart is being used. The owner must submit to the OCMI details and calculations of any alterations to a crane which were accomplished without manufacturer's documentation in order to verify the rated load of the crane.
              (10) Electrical. (a) Multiple power sources do not require an emergency generator; however, storage batteries or approved relay-controlled battery operated lanterns are required to be installed for the emergency lighting system and provide 12 hours of lighting.
              (b) Electrical equipment installed in Class I, division 1 and 2 locations, as defined in Subchapter IA, § 108.170 must be of a suitable type and in good material condition.
              (11) Unfired Pressure Vessels. (a) Unfired pressure vessels built and stamped in accordance with Section VIII of the ASME Code may be continued in service as long as they remain in satisfactory condition. At the original and subsequent inspections for certification, ASME Code pressure vessels must be tested and examined in accordance with the requirements in 46 CFR 61.10-5.
              (b) Unfired pressure vessels which cannot be identified as being constructed to any recognized standard may be continued in service provided that no obvious defects are noted. These pressure vessels shall be hydrostatically tested to one and one half times the working pressure. For pressure vessels that can not be reasonably hydrostatically tested, nondestructive testing may be used to verify the pressure vessels condition for continued serviceability. These pressure vessels will then be stamped with a Coast Guard identification number and periodically tested and examined in accordance with the requirements in 46 CFR 61.10-5.
              (12) Marine Sanitation Devices. (a) All units must meet the provisions of 33 CFR Part 159, Coast Guard Marine Sanitation Devices Regulations. The discharge requirements are compatible with the OCS Orders of the U.S. Geological Survey.

              4. Action. a. The owner of each existing certificated unit must provide the cognizant OCMI a proposed plan to accomplish the requirements in paragraph 3. c. of this NVIC within 60 days from the effective date of the regulations. Most items should be approved at the unit's next inspection for certification; however, where major equipment installations are concerned, the owner may be allowed up to two years to comply with the requirements from the time the OCMI completes his assessment of the proposals.
              b. Application for Original Inspection for Certification. Not later than sixty days from January 3, 1979, application for original inspection for certification of all existing uncertificated units, shall be submitted to the appropriate OCMI. The plans or descriptive data specified in paragraph 3.d(2) of this NVIC along with a proposed plan to bring the unit into compliance should, if possible, be submitted with the application for inspection. If not feasible to assemble all required information in this time frame, an estimated date of submittal shall be indicated on the application. Arrangements should be made to commence the original inspection for certification with due consideration for the unit's operating situation.
              c. To the extent possible the same inspection team will conduct the inspection of all existing uncertificated units in a geographical area. It may be advantageous to conduct the original inspection in conjunction with an impending special or periodic survey, drydocking or availability period. Units under construction will receive primary consideration by the OCMI for the allocation of time and personnel so that any problems can be identified while the unit is in the most advantageous situation to apply corrections.
              d. The variety of designs and arrangements presented by existing uninspected MODU's makes it impractical to prescribe detailed standards for all existing units. The procedures followed to implement this NVC must provide the necessary flexibility. Items which must be taken into consideration in applying this NVIC are listed below. Categorizing units into groups to which the same items apply will be of value during the inspection process. These items are:
              • Type
              • Builder
              • Model
              • Date build
              • Classed by ABS or other classification society
              • Load Line assignment
              • Operating history (including geographical areas)
              • Present location
              e. Issuance of the Original Certificate of Inspection. The intent of the original inspection of existing uncertificated units is to identify and commence correction of any unsafe conditions and/or equipment deficiencies and to issue the unit an original Certificate of Inspection. A reasonable period of time will be permitted to correct minor deficiencies. Those items directly affecting personnel safety and health will require immediate attention to correct the unsafe condition. Extensive deficiencies, such as those involving structural aspects or equipment may require up to two years to remedy. Additional times may be allowed if repair facilities are not available to coastal areas adjacent to the unit's area of operation. Where manifestly unsafe conditions are found, the OCMI may require that the unit discontinue operations until such conditions are corrected. If the owner or operator feels aggrieved by the decision of the OCMI, the appeals procedures of 46 CFR 2.01-70 are applicable.
              f. Questions concerning this NVIC should be referred to the Commandant (CG-CVC).

            Subpart 111.05—Equipment Ground, Ground Detection, and Grounded Systems

              § 111.05-1
              Purpose.
              This subpart contains requirements for the grounding of electric systems, circuits, and equipment.

                Note:
                Circuits are grounded to limit excessive voltage from lightning, transient surges, and unintentional contact with higher voltage lines, and to limit the voltage to ground during normal operation. Conductive materials enclosing electric conductors and equipment, or forming part of that equipment, are grounded to prevent a voltage above ground on the enclosure materials.

              (a) The aggregate capacity of the electric ship's service generating sources required in § 111.10-3 must be sufficient for the ship's service loads.

              (b) With the ship's service generating source of the largest capacity stopped, the combined capacity of the remaining electric ship's service generating source or sources must be sufficient to supply those services necessary to provide normal operational conditions of propulsion and safety, and minimum comfortable conditions of habitability. Habitability services include cooking, heating, air conditioning (where installed), domestic refrigeration, mechanical ventilation, sanitation, and fresh water.
              (c) The capacity of the ship's service generating sources must be sufficient for supplying the ship's service loads without the use of a generating source which is dependent upon the speed or direction of the main propelling engines or shafting.
              (d) Operating generators must provide a continuous and uninterrupted source of power for the ship's service load under normal operational conditions. Any vessel speed change or throttle movement must not cause a ship's service load power interruption.
              (e) Vessels with electric propulsion that have two or more constant-voltage generators which supply both ship's service and propulsion power do not need additional ship's service generators provided that with any one propulsion/ship's service generator out of service the capacity of the remaining generator(s) is sufficient for the electrical loads necessary to provide normal operational conditions of propulsion and safety, and minimum comfortable conditions of habitability.
              (f) A generator driven by a main propulsion unit (such as a shaft generator) which is capable of providing electrical power continuously, regardless of the speed and direction of the propulsion shaft, may be considered one of the ship's service generating sets required by § 111.10-3. A main-engine-dependent generator which is not capable of providing continuous electrical power may be utilized as a supplemental generator provided that a required ship's service generator or generators having sufficient capacity to supply the ship's service loads can be automatically brought on line prior to the main-engine-dependent generator tripping off-line due to a change in the speed or direction of the main propulsion unit.

              (a) The current-carrying capacity of generator cables must not be:
              (1) Less than 115 percent of the continuous generator rating; or
              (2) Less than 115 percent of the overload for a machine with a 2 hour or greater overload rating.
              (b) Generator cables must not be in the bilges.

              § 111.12-11
              Generator protection.
              (a) Applicability. This section applies to each generator except a propulsion generator.
              (b) General. Each ship's service generator and emergency generator must be protected by an individual, tripfree, air circuit breaker whose tripping characteristics can be set or adjusted to closely match the generator capabilities and meet the coordination requirements of Subpart 111.51. Each circuit breaker must contain the trips required by this section.
              (c) Type of trips. A circuit breaker for a generator must:
              (1) Open upon the shutting down of the prime mover;
              (2) Have longtime overcurrent trips or relays set as necessary to coordinate with the trip settings of the feeder circuit breakers; and

              (3) Not have an instantaneous trip with the exception that an instantaneous trip is required if:

              (i) Three or more alternating-current generators can be paralleled; or
              (ii) The circuit breaker is for a direct current generator.
              (d) Setting of longtime overcurrent trips. The pickup setting of the longtime overcurrent trip of a generator circuit breaker must not be larger than:
              (1) 115 percent of the generator rating for a continuous rated machine; or
              (2) 115 percent of the overload rating for a machine with a 2-hour or greater overload rating.
              (e) Setting of instantaneous trips. The instantaneous trip of a generator circuit breaker must be set above, but as close as practicable to, the maximum asymmetrical short circuit available from any one of the generators that can be paralleled.
              (f) Reverse-power and reverse-current trips. Each generator arranged for parallel operation must have reverse-power or reverse-current trips.
              (g) Location. A ship's service generator overcurrent protective device must be on the ship's service generator switchboard. The generator and its switchboard must be in the same space. (For the purposes of this section, the following are not considered separate from the machinery space: (1) A control room that is inside of the machinery casing and (2) a dedicated switch-gear and semiconductor rectifier (SCR) compartment on a mobile offshore drilling unit that is separate from but directly adjacent to and on the same level as the generator room).
              (h) Three-wire, single-phase and four-wire, three-phase generators. There must be circuit breaker poles for each generator lead, except in the neutral lead.
              (i) Three-wire, direct-current generators. Each three-wire, direct current generator must meet the following requirements:
              (1) Circuit breaker poles. There must be separate circuit breaker poles for the positive and negative leads, and, unless the main poles provide protection, for each equalizer lead. If there are equalizer poles for a three-wire generator, each overload trip must be of the “Algebraic” type. If there is a neutral pole in the generator circuit breaker, there must not be an overload trip element for the neutral pole. In this case, there must be a neutral overcurrent relay and alarm system that is set to function at a current value not more than the neutral rating.
              (2) Equalizer buses. For each three-wire generator, the circuit breaker must protect against a short circuit on the equalizer bus.
              (j) Circuit breaker reclosing. Generator circuit breakers must not automatically close after tripping.

              (5) Switchboard circuits, Subpart 111.30.
              (c) Fuses and circuitbreakers. If the allowable current-carrying capacity of the conductor does not correspond to a standard rating for fuses or circuitbreakers that meets Section 240.6 of NFPA NEC 2002 or IEC 60092-202 (both incorporated by reference; see 46 CFR 110.10-1), then the next larger such rating is acceptable, except that:
              (1) This rating must not be larger than 150 percent of the current-carrying capacity of the conductor; and
              (2) The effect of temperature on the operation of fuses and thermally controlled circuitbreakers must be taken into consideration.
              (d) Parallel overcurrent protective devices. An overcurrent protective device must not be connected in parallel with another overcurrent protective device.
              (e) Thermal devices. No thermal cutout, thermal relay, or other device not designed to open a short circuit may be used for protection of a conductor against overcurrent due to a short circuit or ground, except in a motor circuit as described in Article 430 of NFPA NEC 2002 or in IEC 60092-202.
              (f) Ungrounded conductors. A fuse or overcurrent trip unit of a circuit breaker must be in each ungrounded conductor. A branch switch or circuit breaker must open all conductors of the circuit, except grounded conductors.
              (g) Grounded conductor. An overcurrent device must not be in a permanently grounded conductor, except:
              (1) An overcurrent device that simultaneously opens all conductors of the circuit, unless prohibited by § 111.05-17 for the bus-tie feeder connecting the emergency and main switchboards; and
              (2) For motor-running protection described in Article 430 of NFPA NEC 2002 or in IEC 60092-202.

              Motor controllers and motor-control centers.
              (a) General. The enclosure for each motor controller or motor-control center must meet either NEMA ICS 2 and NEMA ICS 2.3, or Table 5 of IEC 60092-201 (all three standards incorporated by reference; see 46 CFR 110.10-1), as appropriate, for the location where it is installed. In addition, each such enclosure in a hazardous location must meet subpart 111.105 of this part. NEMA ICS 2.4 (incorporated by reference; see 46 CFR 110.10-1) provides guidance on the differences between devices meeting NEMA and those meeting IEC for motor service.
              (b) Low-voltage release. Each motor controller for a fire pump, elevator, steering gear, or auxiliary that is vital to the vessel's propulsion system, except a motor controller for a vital propulsion auxiliary which can be restarted from a central control station, must have low-voltage release if automatic restart after a voltage failure or its resumption to operation is not hazardous. If automatic restart is hazardous, the motor controller must have low-voltage protection. Motor controllers for other motors must not have low-voltage release unless the starting current and the short-time sustained current of the additional low-voltage release load is within the capacity of one ship's service generator. Automatic sequential starting of low-voltage release controllers is acceptable to meet this paragraph.
              (c) Low-voltage protection. Each motor controller must have low-voltage protection, except for the following motor controllers:
              (1) A motor controller that has low-voltage release under paragraph (b) of this section.
              (2) A motor controller for a motor of less than 2 horsepower (1.5 kW).

              Heater circuits.

              (a) If an enclosure for a motor, master switch, or other equipment has an electric heater inside the enclosure that is energized from a separate circuit, the heater circuit must be disconnected from its source of potential by a disconnect device independent of the enclosure containing the heater. The heater disconnecting device must be adjacent to the equipment disconnecting device. A fixed sign, warning the operator to open both devices, must be on the enclosure of the equipment disconnect device, except as in paragraph (b) of this section.
              (b) If the location of the enclosure for a motor, master switch, or other equipment for deck machinery is remote from the motor and controller disconnect device, a sign must be fixed to the enclosure if the disconnect arrangement required by paragraph (a) of this section is not used. The sign must warn the operator of the presence of two sources of potential within the enclosure and show the location of the heater circuit disconnect device.

              Remote control, interlock, and indicator circuits.
              (a) Overcurrent protection. A conductor of a control, interlock, or indicator circuit of a motor controller must be protected against overcurrent unless:
              (1) The conductor is wholly within the controller enclosure;
              (2) The rating or setting of the branch circuit overcurrent device is not more than 300 percent of the current-carrying capacity of the control, interlock, or indicator circuit conductor;
              (3) There is an overcurrent device in each side of the line that has a rating or setting of not more than 300 percent of the current-carrying capacity of the control, electrical interlock, or indicator circuit conductor, except if under operating conditions there is no appreciable difference in potential between the external conductors, overcurrent protection need only be at the supply of that side of the line; or
              (4) The opening of the control, interlock, or indicator circuit creates a hazard.

                Note:
                For overcurrent protection of steering gear control and indicator circuits, see Subpart 111.93 of this chapter.

              (b) Accidental ground. The controller must be designed to prevent an accidental ground in a remote control circuit from causing the stop switches to fail to operate or causing the motor to start.
              (c) Source of potential. The potential for a control, interlock, or indicator circuit must be derived from the load side of the motor and controller disconnect device, except if the control functions require circuits that must be common to two or more controllers, the switching arrangement in paragraph (d) of this section must be met.
              (d) Switching. In the design of a control, interlock, or indicator circuit, all practicable steps must be taken to eliminate all but one source of power in an enclosure. If the control functions make it impracticable to energize a control interlock or indicator circuit from the load side of a motor and controller disconnect device and the voltage of the control, interlock, or indicator circuit is more than 24 volts, there must be one of the following alternative methods of switching:
              (1) Each conductor of a control, interlock, or indicator circuit must be disconnected from all sources of potential by a disconnect device independent of the motor and controller disconnect device. The two independent devices must be adjacent to each other, and a fixed sign, warning the operator to open both devices to disconnect completely the motor and controller, must be on the exterior of the door of the main disconnect device.

              (2) Each conductor of a control, interlock, or indicator circuit must be disconnected from all sources of power by a disconnect device actuated by the opening of the controller door, or the power must first be disconnected to allow opening of the door. The disconnect device and its connections, including each terminal block for terminating the vessel's wiring, must have no electrically uninsulated or unshielded surface. When this type of disconnect device is used for vital auxiliary circuits, a nameplate must be affixed to the vital auxiliary motor controller door that warns that opening the door will trip a vital auxiliary off-line.

              (a) Passenger vessels. On a passenger vessel with fire bulkheads forming main vertical and horizontal fire zones, the lighting distribution system, including low location egress lighting where installed, must be arranged so that, to the maximum extent possible, a fire in any main vertical and horizontal fire zone does not interfere with the lighting in any other fire zone. This requirement is met if main and emergency feeders passing through any zone are separated both vertically and horizontally as widely as practicable.
              (b) Machinery spaces. Lighting for enginerooms, boilerrooms, and auxiliary machinery spaces must be supplied from two or more feeders. One of these feeders must be a ship's service feeder.

            Subpart 112.01—Definitions of Emergency Lighting and Power Systems

              § 112.01-1
              Purpose.
              The purpose of this subpart is to define types of emergency lighting and power systems.

              § 112.01-5
              Manual emergency lighting and power system.
              A manual emergency lighting and power system is one in which a single manual operation, such as the manual operation of a switch from an “off” to an “on” position, is necessary to cause the emergency power source to supply power to the emergency loads.

              § 112.01-10
              Automatic emergency lighting and power system.
              An automatic emergency lighting and power system is one in which a reduction in potential from the ship's service power and lighting plant causes the emergency power source to supply power to the emergency loads.

              § 112.01-15
              Temporary emergency power source.
              A temporary emergency power source is one of limited capacity that carries, for a short time, selected emergency loads while an emergency power source of larger capacity is being started.

              § 112.01-20
              Final emergency power source.
              A final emergency power source is one that functions after the temporary emergency power source is disconnected.

            Subpart 112.05—General

              § 112.05-1
              Purpose; preemptive effect.
              (a) The purpose of this part is to ensure a dependable, independent, and dedicated emergency power source with sufficient capacity to supply those services that are necessary for the safety of the passengers, crew, and other persons in an emergency and those additional loads that may be authorized under paragraph (c) of this section.
              (b) No load may be powered from an emergency power source, except:
              (1) A load required by this part to be powered from the emergency power source;
              (2) A bus-tie to the main switchboard that meets § 112.05-3; and
              (3) Emergency loads that may be necessary to maintain or restore the propulsion plant, such as control systems, controllable pitch propellers, hydraulic pumps, control air compressors, and machinery necessary for dead-ship start-up.
              (c) Other loads may be authorized by the Commanding Officer, Marine Safety Center (MSC), to be connected to the emergency source of power to provide an increased level of safety in recognition of a unique vessel mission or configuration. When these loads are authorized, the emergency power source must—
              (1) Be sized to supply these loads using a unity (1.0) service factor; or
              (2) Be provided with automatic load shedding that removes these loads and operates before the emergency generator trips due to overload. The automatic load shedding circuit breakers must be manually reset.
              (d) The regulations in this part have preemptive effect over State or local regulations in the same field.

              § 112.05-3
              Main-emergency bus-tie.
              Each bus-tie between a main switchboard and an emergency switchboard must:
              (a) Disconnect automatically upon loss of potential at the emergency switchboard;
              (b) Be arranged to prevent parallel operation of an emergency power source with any other source of electric power, except for interlock systems for momentary transfer of loads; and
              (c) If arranged for feedback operation, open automatically upon overload of the emergency power source before the emergency power source is tripped off the line from the overload.

              § 112.05-5
              Emergency power source.

              (a) The emergency power source must meet table 112.05-5(a) and have the capacity to supply all loads that are simultaneously connected to it, except a load on a bus-tie to the main switchboard or non-required loads that are connected in accordance with § 112.05-1(c).

              Weathertight means that water will not penetrate in any sea condition, except that “weathertight equipment” means equipment constructed or protected so that exposure to a beating rain will not result in the entrance of water.

              Well deck vessel means a vessel with a weather deck fitted with solid bulwarks that impede the drainage of water over the sides or a vessel with an exposed recess in the weather deck extending more than one-half of the length of the vessel measured over the weather deck.

              Wire means an individual insulated conductor without an outer protective jacket.

              Work space means a space, not normally occupied by a passenger, in which a crew member performs work and includes, but is not limited to, a galley, operating station, or machinery space.

              When required.

              (a) A vessel to which this subchapter applies may not be operated without having on board a valid U.S. Coast Guard Certificate of Inspection.

              (b) Except as noted in § 115.114 of this part, each vessel inspected and certificated under the provisions of this subchapter must, when any passengers are aboard during the tenure of the certificate, be in full compliance with the terms of the certificate.
              (c) If necessary to prevent delay of the vessel, a temporary Certificate of Inspection may be issued pending the issuance and delivery of the regular Certificate of Inspection. The temporary certificate must be carried in the same manner as the regular certificate and is considered the same as the regular Certificate of Inspection which it represents.
              (d) A vessel on a foreign voyage between a port in the United States and a port in a foreign country, whose Certificate of Inspection expires during the voyage, may lawfully complete the voyage without a valid Certificate of Inspection provided the voyage is completed within 30 days of expiration and the certificate did not expire within 15 days of sailing on the foreign voyage from a U.S. port.

              § 115.103
              Description.
              The Certificate of Inspection issued to a vessel describes the vessel, the route(s) that it may travel, the minimum manning requirements, the survival and rescue craft carried, the minimum fire extinguishing equipment and life jackets required to be carried, the maximum number of passengers and total persons that may be carried, the number of passengers the vessel may carry in overnight accommodation spaces, the name of the owner and managing operator, any equivalences accepted or authorized by the Commandant or any Officer in Charge, Marine Inspection (OCMI) in accordance with § 114.540 or § 114.550 of this subchapter and such other conditions of operations as may be determined by the cognizant OCMI.

              § 115.110
              Routes permitted.

              (a) The area of operation for each vessel and any necessary operational limits are determined by the cognizant OCMI, and recorded on the vessel's Certificate of Inspection. Each area of operation, referred to as a route, is described on the Certificate of Inspection under the major headings “Oceans,” “Coastwise,” “Limited Coastwise,” “Great Lakes,” “Lakes, Bays, and Sounds,” or “Rivers,” as applicable. Further limitations imposed or extensions granted are described by reference to bodies of waters, geographical points, distance from geographical points, distances from land, depths of channel, seasonal limitations, and similar factors.
              (b) Operation of a vessel on a route of lesser severity than those specifically described or designated on the Certificate of Inspection is permitted unless expressly prohibited on the certificate of Inspection. The general order of severity of routes is: oceans, coastwise, limited coastwise, Great Lakes, lakes, bays and sounds, and rivers. The cognizant OCMI may prohibit a vessel from operating on a route of lesser severity than the primary route a vessel is authorized to operate on if local conditions necessitate such a restriction.
              (c) Non-self-propelled vessels are prohibited from operating on an oceans, coastwise, limited coastwise, or Great Lakes route unless the Commandant approves such a route.
              (d) When designating a permitted route or imposing any operational limits on a vessel, the OCMI may consider:
              (1) Requirements of this subchapter for which compliance is based on the route of the vessel;
              (2) The performance capabilities of the vessel based on design, scantlings, stability, subdivision, propulsion, speed, operating modes, maneuverability, and other characteristics;
              (3) The suitability of the vessel for night-time operations; and
              (4) The suitability of the vessel for use in all environmental conditions.

              § 115.112
              Total persons permitted.
              The cognizant Officer in Charge, Marine Inspection (OCMI) determines the total number of persons permitted to be carried on a vessel. In determining the total number of persons, the OCMI may consider the total weight of passengers, crew, and variable loads; stability restrictions and subdivision requirements of the vessel; the vessel's route, general arrangement, means of escape, and lifesaving equipment; minimum manning requirements; and the maximum number of passengers permitted in accordance with § 115.113 of this subpart.
              [USCG-2007-0030, 75 FR 78082, Dec. 14, 2010]

              § 115.113
              Passengers permitted.
              (a) The maximum number of passengers permitted must be not more than that allowed by the requirements of this section, except as authorized by the OCMI under paragraph (d) of this section.
              (b) The maximum number of passengers permitted on any vessel may be the greatest number permitted by the length of rail criterion, deck area criterion, or fixed seating criterion described in this paragraph or a combination of these criteria as allowed by paragraph (c) of this section.
              (1) Length of rail criterion. One passenger may be permitted for each 760 millimeters (30 inches) of rail space available to the passengers at the periphery of each deck. The following rail space may not be used in determining the maximum number of passengers permitted:
              (i) Rail space in congested areas unsafe for passengers, such as near anchor handling equipment or line handling gear, in the way of sail booms, running rigging, or paddle wheels, or along pulpits;
              (ii) Rail space on stairways; and
              (iii) Rail space where persons standing in the space would block the line of vision of the credentialed individual operating the vessel.
              (2) Deck area criterion. One passenger may be permitted for each 0.9 square meters (10 square feet) of deck area available for the passengers' use. In computing such deck area, the areas occupied by the following must be excluded:
              (i) Areas for which the number of persons permitted is determined using the fixed seating criteria;
              (ii) Obstructions, including stairway and elevator enclosures, elevated stages, bars, and cashier stands, but not including slot machines, tables, or other room furnishings;
              (iii) Toilets and washrooms;

              (iv) Spaces occupied by and necessary for handling lifesaving equipment, anchor handling equipment or line handling gear, or in the way of sail booms or running rigging;
              (v) Spaces below deck that are unsuitable for passengers or that would not normally be used by passengers;
              (vi) Interior passageways less than 840 millimeters (34 inches) wide and passageways on open deck, less than 710 millimeters (28 inches) wide;
              (vii) Bow pulpits, swimming platforms and areas that do not have a solid deck, such as netting on multi-hull vessels;
              (viii) Deck areas in way of paddle wheels; and
              (ix) Aisle area provided in accordance with § 116.820(d) of this chapter.
              (3) Fixed seating criterion. One passenger may be permitted for each 455 millimeter (18 inches) of width of fixed seating provided by § 116.820 of this chapter. Each sleeping berth in overnight accommodation spaces shall be counted as only one seat.
              (c) Different passenger capacity criteria may be used on each deck of a vessel and added together to determine the total passenger capacity of that vessel. Where seats are provided on part of a deck and not on another, the number of passengers permitted on a vessel may be the sum of the number permitted by the seating criterion for the space having seats and the number permitted by the deck area criterion for the space having no seats. The length of rail criterion may not be combined with either the deck area criterion or the fixed seating criterion when determining the maximum number of passengers permitted on an individual deck.
              (d) For a vessel operating on short runs on protected waters such as a ferry, the cognizant OCMI may give special consideration to increases in passenger allowances.

              § 115.114
              Alternative requirements for a vessel operating as other than a small passenger vessel.
              (a) When authorized by the cognizant OCMI by an endorsement of the vessel's Certificate of Inspection, a small passenger vessel carrying six or less passengers, or operating as a commercial fishing vessel or other uninspected vessel, or carrying less than twelve passengers and operating as a recreational vessel, need not meet requirements of:
              (1) Subparts C, D, and E, of part 117 of this chapter if the vessel is in satisfactory compliance with the lifesaving equipment regulations for an uninspected vessel or recreational vessel in similar service;

If the vessel becomes due for a drydock examination or an internal structural examination during the voyage, it may lawfully complete the voyage prior to the examination if it undergoes the required examination upon completion of the voyage to the United States but not later than 30 days after the examination is due. If the vessel is due for an examination within 15 days of sailing on an international voyage from a United States port, it must undergo the required examination before sailing.
              (c) If your vessel is operated on other than international voyages and does not meet the conditions in paragraph (d) of this section, it must undergo a drydock and internal structural examination as follows unless it has been approved to undergo an underwater survey (UWILD) per § 115.615 of this part:
              (1) A vessel that is exposed to salt water more than three months in any 12 month period since the last examination must undergo a drydock examination and an internal structural examination at least once every two years; and
              (2) A vessel that is exposed to salt water not more than three months in any 12 month period since the last examination must undergo a drydock examination and an internal structural examination at least once every five years.
              (d) Whenever damage or deterioration to hull plating or structural members that may affect the seaworthiness of a vessel is discovered or suspected, the cognizant OCMI may conduct an internal structural examination in any affected space, including fuel tanks, and may require the vessel to be drydocked or taken out of service to assess the extent of the damage, and to effect permanent repairs. The OCMI may also decrease the drydock examination intervals to monitor the vessel's structural condition.
              (e) For a vessel that is eligible per § 115.625 of this part and the owner opts for an alternate hull examination with the underwater survey portion conducted exclusively by divers, the vessel must undergo two alternate hull exams and two internal structural exams within any five-year period. If a vessel completes a satisfactory alternate hull exam, with the underwater survey portion conducted predominantly by an approved underwater remotely operated vehicle (ROV), the vessel must undergo one alternate hull and one internal structural exam, within any five-year period. The vessel may undergo a drydock exam to satisfy any of the required alternate hull exams.

              § 115.620
              Description of the Alternative Hull Examination (AHE) Program for certain passenger vessels.

              The Alternative Hull Examination (AHE) Program provides you with an alternative to a drydock examination by allowing your vessel's hull to be examined while it remains afloat. If completed using only divers, this program has four steps: the application process, the preliminary examination, the pre-survey meeting, and the hull examination. If the vessel is already participating in the program or if a remotely operated vehicle (ROV) is used during the program, the preliminary exam step may be omitted. Once you complete these steps, the Officer in Charge, Marine Inspection (OCMI), will evaluate the results and accept the examination as a credit hull exam if the vessel is in satisfactory condition. If only divers are used for the underwater survey portion of the examination process, you may receive credit for a period of time such that subsequent AHEs would be conducted at intervals of twice in every five years, with no more than three years between any two AHEs. The OCMI may waive an underwater survey in accordance with § 115.655(d) provided that the interval does not exceed five years between any two underwater surveys. If an underwater ROV is used as the predominate method to examine the vessel's underwater hull plating, you may receive credit up to five years. At the end of this period, you may apply for further participation under the AHE Program.

                Note to § 115.620:
                The expected hull coverage when using an ROV must be at least 80 percent.

              § 115.645
              Alternative Hull Examination (AHE) Procedure.
              (a) To complete the underwater survey you must—
              (1) Perform a general examination of the underwater hull plating and a detailed examination of all hull welds, propellers, tailshafts, rudders, and other hull appurtenances;
              (2) Examine all sea chests;
              (3) Remove and inspect all sea valves in the presence of a marine inspector once every five years;
              (4) Remove all passengers from the vessel when the sea valves are being examined, if required by the Officer in Charge, Marine Inspection (OCMI);
              (5) Allow access to all internal areas of the hull for examination, except internal tanks that carry fuel (unless damage or deterioration is discovered or suspect), sewage, or potable water. Internal sewage and potable water tanks may be examined visually or by non-destructive testing to the satisfaction of the attending marine inspector; and
              (6) Meet the requirements in § 115.650 of this part.
              (b) A marine inspector may examine any other areas deemed necessary by the OCMI.

              (c) If the AHE reveals significant deterioration or damage to the vessel's hull plating or structural members, the OCMI must be immediately notified. The OCMI may require the vessel be drydocked or otherwise taken out of service to further assess the extent of damage or to effect permanent repairs if the assessment or repairs cannot be completed to the satisfaction of the OCMI while the vessel is waterborne.
              [USCG-2000-6858, 67 FR 21081, Apr. 29, 2002, as amended by USCG-2000-6858, 69 FR 47383, Aug. 5, 2004]

              § 115.650
              Alternative Hull Examination (AHE) Program options: Divers or underwater ROV.
              To complete your underwater survey, you may use divers or an underwater remotely operated vehicle (ROV).
              (a) If you use divers to conduct the underwater survey, you must—
              (1) Locate the vessel so the divers can work safely under the vessel's keel and around both sides. The water velocity must be safe for dive operations;
              (2) Provide permanent hull markings, a temporary grid system of wires or cables spaced not more than 10 feet apart and tagged at one-foot intervals, or any other acoustic or electronic positioning system approved by the OCMI to identify the diver's location with respect to the hull, within one foot of accuracy;
              (3) Take ultrasonic thickness gaugings at a minimum of 5 points on each plate, evenly spaced;
              (4) Take hull plating thickness gaugings along transverse belts at the bow, stern, and midships, as a minimum. Plating thickness gaugings must also be taken along a longitudinal belt at the wind and water strake. Individual gaugings along the transverse and longitudinal belts must be spaced no more than 3 feet apart;
              (5) Ensure the third party examiner observes the entire underwater examination process;
              (6) Record the entire underwater survey with audio and video recording equipment and ensure that communications between divers and the third party examiner are recorded; and
              (7) Use appropriate equipment, such as a clear box, if underwater visibility is poor, to provide the camera with a clear view of the hull.
              (b) You may use an underwater ROV to conduct the underwater survey. The underwater ROV operating team, survey process and equipment, quality assurance methods, and the content and format of the survey report must be accepted by the Officer in Charge, Marine Inspection (OCMI) prior to conducting the survey. If you choose this option, you must—
              (1) Locate the vessel to ensure that the underwater ROV can operate effectively under the vessel's keel and around both sides;
              (2) Employ divers to examine any sections of the hull and appurtenances that the underwater ROV cannot access or is otherwise unable to evaluate; and
              (3) If the OCMI determines that the data obtained by the ROV, including non-destructive testing results, readability of the results, and positioning standards, will not integrate into the data obtained by the divers, then a third party examiner must be present during the divers portion of the examination.
              [USCG-2000-6858, 67 FR 21081, Apr. 29, 2002, as amended by USCG-2000-6858, 69 FR 47383, Aug. 5, 2004]

              § 115.655
              Hull examination reports.
              (a) If you use only divers for the underwater survey portion of the Alternative Hull Examination (AHE), you must provide the Officer in Charge, Marine Inspection (OCMI), with a written hull examination report. This report must include thickness gauging results, bearing clearances, a copy of the audio and video recordings, and any other information that will help the OCMI evaluate your vessel for a credit hull exam. The third party examiner must sign the report and confirm the validity of its contents.
              (b) If you use an underwater remotely operated vehicle (ROV) as the predominate means to examine the vessel's underwater hull plating, you must provide the OCMI with a report in a format that is acceptable to the OCMI, per § 115.650(b) of this part.

              (c) The OCMI will evaluate the hull examination report and grant a credit hull exam if satisfied with the condition of the vessel. If approved and you exclusively use divers to examine the hull plating, you may receive a credit hull exam to 36 months. (Underwater examinations are required twice every 5 years). If approved and you use an underwater ROV as the predominant means to examine the underwater hull plating, you may receive a credit hull exam up to 60 months (5 years).

              (d) At least 60 days prior to each scheduled underwater exam, the owner may request a waiver from the OCMI if:
              (1) A satisfactory exam has been completed within the last three years;
              (2) The conditions during the last exam allowed at least 80 percent of the bottom surface to be viewed and recorded; and
              (3) The results of the last exam indicated that an extended interval is safe and reasonable.

              Continued participation in the Alternative Hull Examination (AHE) Program.
              (a) To continue to participate in the AHE Program, vessel operators must conduct an annual hull condition assessment. At a minimum, vessel operators must conduct an internal examination and take random hull gaugings internally during the hull condition assessment, unless waived by the Officer in Charge, Marine Inspection (OCMI). If the annual hull assessment reveals significant damage or corrosion, where temporary repairs have been made, or where other critical areas of concern have been identified, the OCMI may require an expanded examination to include an underwater hull examination using divers. If an underwater examination is required, the examination must focus on areas at higher risk of damage or corrosion and must include a representative sampling of hull gaugings.
              (b) If an underwater survey is required for the annual hull condition assessment, the OCMI may require the presence of a third party examiner and a written hull examination report must be submitted to the OCMI. This report must include thickness gauging results, a copy of the audio and video recordings and any other information that will help the OCMI evaluate your vessel for continued participation in the AHE program. The third party examiner must sign the report and confirm the validity of its contents.
              (c) You must submit your preventive maintenance reports or checklists on an annual basis to the OCMI. These reports or checklists must conform to the plans you submitted in your application under § 115.630 of this part, which the OCMI approved.
              (d) Prior to each scheduled annual hull condition assessment—
              (1) The owner may submit to the OCMI a plan for conducting the assessment, or a request for a waiver of this requirement, no fewer than 30 days before the scheduled assessment; and
              (2) The OCMI may reduce the scope or extend the interval of the assessment if the operational, casualty, and deficiency history of the vessel, along with a recommendation of the vessel's master, indicates that it is warranted.

              § 116.438
              Stairtowers, stairways, ladders, and elevators.
              (a) A vessel carrying more than 600 passengers or with overnight accommodations for more than 49 passengers must meet the requirements for stairways, ladders, and elevators in § 72.05-20 of this chapter.
              (b) Materials. (1) Stairways, stairtowers, ladders, elevators, and landings must be designed with sufficient strength to sustain a load of 4.8 kPa (100 pounds per square foot) with a safety factor of 4, based on ultimate strength of the material;
              (2) All stairways, ladders, elevators, and landings within machinery spaces and cargo holds must be composed of steel; and

              (3) All stringers, treads, and all platforms and landings of all stairways shall be composed of steel, and risers must be of approved incombustible material, except that:

              (i) Stairways, ladders, elevators, stringers, treads, platforms, and landings protected from potential fire exposure by being in either exterior locations or within protective enclosure bulkheads, decks and doors as described in the requirements of paragraph (j), may be constructed of approved incombustible material; and
              (ii) All stairways, ladders, elevators, stringers, treads, platforms, and landings subject to potential fire exposure and not within a protective enclosure must be composed of steel unless their failure will not hinder fire fighter access or debarkation.
              (c) A stairway or stairtower must be fitted with handrails on both sides at a vertical height above the tread at its nosing of between 840 and 910 millimeters (33 and 36 inches). A stairway or stairtower of more than 1,680 millimeters (66 inches) in width must also be fitted with a center handrail.
              (d) A handrail fitted in a stairtower, stairway, landing, ladder, or elevator must be constructed of noncombustible material.
              (e) A stairway or stairtower must be clear of all obstructions other than handrails.
              (f) Curved, spiral, or winding stairways are permitted only with the specific approval of the Commandant.
              (g) Differences in the depth of tread or height of riser of stairs in different flights of stairs in a stairway or stairtower must be minimized. In an individual flight of stairs in a stairway or stairtower, the depth of the tread and the height of riser shall not have a variance exceeding 5 millimeters (0.19685 inches).
              (h) In a stairway or stairtower, the sum of the riser height and tread depth must be at least 432 millimeters (17 inches) and not more than 455 millimeters (18 inches). A stairway or stairtower having treads less than 254 millimeters (10 inches) in depth must have a nosing of 12.7 millimeters (0.5 inches) in width.
              (i) Landings for stairways and stairtowers must meet the following requirements:
              (1) A clear landing having an area at least equal to the square of the tread width must be provided at the top and bottom of each stairway; and
              (2) Any interruption or change of direction in a stairway must be accomplished by means of an intermediate landing of a width and length at least equal to the tread width of the stairway.
              (j) A stairway or stairtower must not have an angle of inclination from the horizontal of more than 40 degrees. However, stairways accessing spaces visited solely by crew members must not have an angle of inclination from the horizontal of more than 50 degrees. The Commanding Officer, Marine Safety Center may approve higher angles of inclination for spaces with severe space constraints.
              (k) Where a continuous vertical deck penetration for a stairway or elevator exceeds one deck, the integrity of all decks must be assured by enclosure bulkheads and decks meeting the requirements of §§ 116.415(b) and 116.415(c) of this part. Doors meeting the requirements of §§ 116.435(b) and 116.435(c) of this part must be fitted in the enclosure at each deck serviced.
              (l) Where a vertical deck penetration for a stairway or elevator involves only one deck, the integrity of the deck must be assured as required by paragraph (k) of this section. Alternatively the integrity of the deck may be maintained at one level only by means of bulkheads of the same fire control boundary rating as the deck penetrated. A door meeting the requirements of §§ 116.435(b) and 116.435(c) of this part must be fitted in the enclosure. In spaces containing a balcony, the integrity of the balcony deck in the way of stairways or elevators need not be assured. However, such stairways must not be considered to be a means of escape.
              (m) Arrangements. (1) Each main vertical zone with more than two deck levels, each having enclosed or partially enclosed accommodation spaces, other than washroom or toilet spaces and open decks, must be served by at least one stairtower, so that a person may escape from any accommodation space or any other space where persons may be normally quartered or employed, to all other decks having any such spaces within the same main vertical zone, without coming out of the stairtower enclosure. Where a stairtower is accessible from two main vertical zones, it may be considered as the required stairtower for both main vertical zones provided all boundaries of the stairtower meet main vertical zone boundary requirements contained in § 116.415 of this part.
              (2) Each stairtower must give access to an embarkation station or an area of refuge identified in the emergency escape plan required by § 116.520.
              (3) Stairtowers must not give direct access to overnight accommodations or spaces of type 9, 10, 11, or 12.
              (4) A stairtower is not required to extend below deck to serve spaces in which a fire is likely to originate if one of the means of escape is:
              (i) A stairway that leads directly to a weather deck; or
              (ii) A stairway leading to a stairtower enclosure that includes self closing fire doors at both the top and bottom; or
              (iii) An alternative stairtower arrangement providing an equivalent level of safety is acceptable to the Commanding Officer, Marine Safety Center.
              (5) The Commanding Officer, Marine Safety Center may accept other means of escape in combination with a stairtower provided the exits open directly to weather or through a main vertical zone bulkhead.
              (6) For vessels in which a stairtower is not required, a stairway must provide a means of escape for each deck of the main vertical zone.
              (n) The minimum tread width of a stairway or stairtower must be 8.4 millimeters (0.333 inches) for each person served, but must not be less than 910 millimeters (36 inches). However, in stairways accessing spaces utilized solely by crew members, the minimum tread width must be 8.4 millimeters (0.333 inches) for each person served, but not less than 710 millimeters (28 inches).
              (1) The minimum tread width of a stairway or stairtower must be determined for each deck considering only those persons on that deck, except as provided in paragraph (n)(3) of this section. Once a minimum tread width has been established at any deck, it must not be decreased in the direction of escape.
              (2) In determining the number of persons served, a space must be considered to contain at least the number of persons as follows:
              (i) Passenger overnight accommodation spaces: Designed capacity;
              (ii) Accommodation spaces having fixed seating for passengers: Maximum seating capacity;
              (iii) Public spaces, including spaces such as casinos, restaurants, club rooms, and cinemas, and public accommodation spaces as defined in § 114.400 of this subchapter, except overnight accommodation spaces: One person for each 0.9 square meters (10 square feet) of deck area. In computing such deck area, the following areas must be excluded:
              (A) Areas for which the number of persons permitted is determined using the fixed seating criterion;
              (B) Obstructions, including stairway and elevator enclosures, elevated stages, bars, and cashier stands, but not including slot machines, tables, or other room furnishings;
              (C) Toilets and washrooms;
              (D) Interior passageways less than 850 millimeters (34 inches) wide and passageways on open deck less than 710 millimeters (28 inches) wide;
              (E) Spaces necessary for handling lifesaving equipment, anchor handling equipment, or line handling gear, or in way of sail booms or running rigging; and
              (F) Bow pulpits, swimming platforms, and areas that do not have a solid deck, such as netting on multi hull vessels;
              (iv) Crew overnight accommodation spaces: Two-thirds designed capacity; and
              (v) Work spaces: Occupancy under normal operating conditions.

              (3) If a stairway forms part of a normal embarkation or debarkation route, or egress route to an area of refuge, the number of persons using the stairway for that purpose must be used in determining the minimum tread width. The Commanding Officer, Marine Safety Center, may approve a narrower stairway width if a narrower stairway will not unreasonably impede the flow of persons out of the space requiring egress or from an area of refuge to an embarkation station. Specific consideration can be given by the Marine Safety Center to the arrangement of landing area in excess of that required by paragraph (i) of this section when considering the approval of a narrower stairway width. However, the stairway width must be at least 910 millimeters (36 inches) unless the stairway is utilized solely by crew members, in which case the minimum tread width must be at least 710 millimeters (28 inches).
              (4) If more than one stairtower serves a main vertical zone, the number of persons in that main vertical zone may be distributed among the stairtowers.

              (b) Each level of a space containing a balcony must have two independent means of escape that meet the requirements of § 116.500 of this part.
              (c) For the purpose of main vertical zone bulkhead spacing requirements, the length of the space to which the balcony opens is considered to be increased by an amount equal to the gross area of the balcony divided by the average width of the space. If this equivalent main vertical zone length exceeds 40 meters (131 feet), the space must meet the requirements of paragraph (d) of this section. The actual length of the space may not exceed 40 meters (131 feet).
              (d) If the equivalent main vertical zone length under paragraph (c) of this section exceeds 40 meters (131 feet), both decks connected by the balcony must be protected with an automatic sprinkler system meeting NFPA 13.
              (e) If the unobstructed balcony opening area is less than 93 square meters (1,000 square feet), the opening must be protected in accordance with NFPA 13 or other standard specified by the Commandant. The horizontal projection area of stairs, escalators, statues, or other obstructions must be subtracted from the total balcony opening area for purposes of computation of unobstructed balcony opening area.

            Subpart E—Escape and Embarkation Station Requirements

              § 116.500
              Means of escape.
              (a) Except as otherwise provided in this section, each space accessible to passengers or used by the crew on a regular basis, must have at least two means of escape, one of which must not be a watertight door.
              (b) The two required means of escape must be widely separated and, if possible, at opposite ends or sides of the space to minimize the possibility of one incident blocking both escapes.
              (c) Subject to the restrictions of this section, means of escape may include normal exits and emergency exits, passageways, stairways, ladders, deck scuttles, and windows.
              (d) The number and dimensions of the means of escape from each space must be sufficient for rapid evacuation in an emergency for the number of persons served as determined using § 116.438(n)(2) of this part.
              (e) The dimensions of a means of escape must be such as to allow easy movement of persons when wearing life jackets. There must be no protrusions in means of escape that could cause injury, ensnare clothing, or damage life jackets.
              (f) The minimum clear opening of a door or passageway used as a means of escape must not be less than 810 millimeters (32 inches) in width, however, doors or passageways used solely by crew members must have a clear opening not less than 710 millimeters (28 inches). The sum of the width of all doors and passageways used as means of escape from a space must not be less than 8.4 millimeters (0.333 inches) multiplied by the number of passengers for which the space is designed.
              (g) A dead end passageway, or the equivalent, of more than 6.1 meters (20 feet) in length is prohibited.
              (h) The maximum allowable travel distance, measured as actual walking distance from the most remote point in a space to the nearest exit, must not be more than 46 meters (150 feet).
              (i) Each door, hatch, or scuttle, used as a means of escape, must be capable of being opened by one person, from either side, in both light and dark conditions. The method of opening a means of escape must be obvious, rapid, and of adequate strength. Handles and securing devices must be permanently installed and not capable of being easily removed.

              (iii) Distribution piping within a space must be proportioned from the distribution line to give proper supply to the outlets without throttling.
              (iv) The number, type, and location of discharge outlets must provide uniform distribution of carbon dioxide throughout a space.
              (v) The total area of all discharge outlets must not exceed 85 percent nor be less than 35 percent of the nominal cylinder outlet area or the area of the supply pipe, whichever is smaller. The nominal cylinder outlet area in square millimeters (inches) is determined by multiplying the factor 0.015 (0.0022 if using square inches) by the total capacity in kilograms (pounds) of all carbon dioxide cylinders in the system, except in no case must the outlet area be of less than 71 square millimeters (0.110 square inches).
              (vi) The discharge of at least 85 percent of the required amount of carbon dioxide must be completed within two minutes.
              (5) When installed in an enclosed ventilation system for rotating electrical propulsion equipment a fixed carbon dioxide system must meet the following requirements.

              (i) The quantity of carbon dioxide in kilograms (pounds) must be sufficient for initial and delayed discharges as required by this paragraph. The initial discharge must be equal to the gross volume of the system in cubic meters divided by 0.624 (10 if using pounds) for ventilation systems having a volume of less than 57 cubic meters (2,000 cubic feet), or divided by 0.749 (12 if using pounds) for ventilation systems having a volume of at least 57 cubic meters (2,000 cubic feet). In addition, there must be sufficient carbon dioxide available to permit delayed discharges to maintain at least a 25 percent concentration until the equipment can be stopped. If the initial discharge achieves this concentration, a delayed discharge is not required.
              (ii) The piping sizes for the initial discharge must be in accordance with Table 118.410(f)(4)(ii) and the discharge of the required amount must be completed within two minutes.
              (iii) Piping for the delayed discharge must not be less than 12.7 millimeters (0.5 inches) nominal pipe size, and need not meet specific requirement for discharge rate.
              (iv) Piping for the delayed discharge may be incorporated with the initial discharge piping.
              (6) When installed in a cargo space a fixed carbon dioxide system must meet the following requirements.
              (i) The number of kilograms (pounds) of carbon dioxide required for each space in cubic meters (feet) must be equal to the gross volume of the space in cubic meters (feet) divided by 1.88 (30 if using pounds).
              (ii) System piping must be of at least 19 millimeters (0.75 inches).
              (iii) No specific discharge rate is required.
              (7) A lockout valve must be provided on any carbon dioxide extinguishing system protecting a space over 6,000 cubic feet in volume and installed or altered after [July 9, 2013. “Altered” means modified or refurbished beyond the maintenance required by the manufacturer's design, installation, operation and maintenance manual.
              (8) The lockout valve must be a manually operated valve located in the discharge manifold prior to the stop valve or selector valves. When in the closed position, the lockout valve must provide complete isolation of the system from the protected space or spaces, making it impossible for carbon dioxide to discharge in the event of equipment failure during maintenance.
              (9) The lockout valve design or locking mechanism must make it obvious whether the valve is open or closed.
              (10) A valve is considered a lockout valve if it has a hasp or other means of attachment to which, or through which, a lock can be affixed, or it has a locking mechanism built into it.
              (11) The master or person-in-charge must ensure that the valve is locked open at all times, except while maintenance is being performed on the extinguishing system, when the valve must be locked in the closed position.
              (12) Lockout valves added to existing systems must be approved by the Commandant as part of the installed system.
              (g) Specific requirements for Halon 1301 systems. (1) A custom engineered fixed gas fire extinguishing system that uses Halon 1301, must comply with the applicable sections of UL 1058 “Halogenated Agent Extinguishing System Units,” and the requirements of this paragraph.
              (2) The Halon 1301 quantity and discharge requirements of UL 1058 apply, with the exception that the Halon 1301 design concentration must be 6 percent at the lowest ambient temperature expected in the space. If the lowest temperature is not known, a temperature of −18 °C (0 °F) must be assumed.
              (3) Each storage cylinder in a system must have the same pressure and volume.

              (4) Computer programs used in designing systems must be approved by an independent laboratory recognized by the Commandant.

                Note to § 118.410(g):
                As of Jan. 1, 1994, the United States banned the production of Halon. The Environmental Protection Agency placed significant restrictions on the servicing and maintenance of systems containing Halon. Vessels operating on an international voyage, subject to SOLAS requirements, are prohibited from installing fixed gas fire extinguishing systems containing Halon.

              (h) Each carbon dioxide extinguishing system installed or altered after July 9, 2013, must have an approved odorizing unit to produce the scent of wintergreen, the detection of which will serve as an indication that carbon dioxide gas is present in a protected area and any other area into which the carbon dioxide may migrate. “Altered” means modified or refurbished beyond the maintenance required by the manufacturer's design, installation, operation and maintenance manual.

              (c) Where sounding pipes are used, each opening must be at least as high as the opening of the fill pipe and they must be kept closed at all times except during sounding.
              (d) Fill pipes and sounding pipes must be so arranged that overflow of liquid or vapor cannot escape to the inside of the vessel.
              (e) Fill pipes and sounding pipes must run as directly as possible, preferably in a straight line, from the deck connection to the top of the tank. Such pipes must terminate on the weather deck and must be fitted with shutoff valves, watertight deck plates, or screw caps, suitably marked for identification. Diesel fill pipes and sounding pipes may terminate at the top of the tank.

              (f) Where a flexible fill pipe section is necessary, suitable flexible tubing or hose having high resistance to salt water, petroleum oils, heat and vibration, may be used. Such hose must overlap metallic pipe ends at least 1.5 times the pipe diameter and must be secured at each end by clamps. The flexible section must be accessible and as near the upper end of the fill pipe as practicable. When the flexible section is a nonconductor of electricity, the metallic sections of the fill pipe separated thereby must be joined by a conductor for protection against generation of a static charge when filling with fuel.

              USCG-1999-4976, 65 FR 6505, Feb. 9, 2000, unless otherwise noted.

              § 126.510
              Annual and periodic inspections.
              (a) Annual inspection. Your vessel must undergo an annual inspection within 3 months before or after each anniversary date, except as required in paragraph (b) of this section.

              (1) You must contact the cognizant OCMI to schedule an inspection at a time and place which he or she approves. No written application is required.
              (2) The scope of the annual inspection is the same as the inspection for certification as specified in § 126.430, but in less detail unless the cognizant marine inspector finds deficiencies or determines that a major change has occurred since the last inspection. If deficiencies are found or a major change to the vessel has occurred, the marine inspector will conduct an inspection more detailed in scope to ensure that the vessel is in satisfactory condition and fit for the service for which it is intended. If your vessel passes the annual inspection, the marine inspector will endorse your current Certificate of Inspection.
              (3) If the annual inspection reveals deficiencies in your vessel's maintenance, you must make any or all repairs or improvements within the time period specified by the OCMI.
              (4) Nothing in this subpart limits the marine inspector from making such tests or inspections he or she deems necessary to be assured of the vessel's seaworthiness.
              (b) Periodic inspection. Your vessel must undergo a periodic inspection within 3 months before or after the second or third anniversary of the date of your vessel's Certificate of Inspection. This periodic inspection will take the place of an annual inspection.
              (1) You must contact the cognizant OCMI to schedule an inspection at a time and place which he or she approves. No written application is required.
              (2) The scope of the periodic inspection is the same as that for the inspection for certification, as specified in § 126.430. The OCMI will insure that the vessel is in satisfactory condition and fit for the service for which it is intended. If your vessel passes the periodic inspection, the marine inspector will endorse your current Certificate of Inspection.
              (3) If the periodic inspection reveals deficiencies in your vessel's maintenance, you must make any or all repairs or improvements within the time period specified by the OCMI.
              (4) Nothing in this subpart limits the marine inspector from conducting such tests or inspections he or she deems necessary to be assured of the vessel's seaworthiness.

              § 126.520
              Certificate of Inspection: Conditions of validity.
              To maintain a valid Certificate of Inspection, you must complete your annual and periodic inspections within the periods specified in § 126.510 (a) and (b) and your Certificate of Inspection must be endorsed.

              § 126.530
              Alternative annual inspection for offshore supply vessels less than 400 gross tons in foreign ports.
              (a) The owner, master or operator of an OSV of less than 400 gross tons may request authorization to conduct an alternative annual inspection in place of the annual inspection described in § 126.510(a) of this subpart. The request must go to the cognizant OCMI assigned responsibility for inspections in the country in which the vessel is operating and will be examined. To qualify for the alternative annual examination, the vessel must meet the following requirements:
              (1) The request must be in writing and be received by the OCMI not later than the anniversary date.
              (2) The vessel is likely to be continuously employed outside of the United States during the 3 months before and after each anniversary date.
              (b) In determining whether to authorize the alternative annual inspection, the OCMI considers the following:
              (1) Information contained in previous examination reports on inspection and drydock, including the recommendation of the then cognizant OCMI for participation in the alternative midperiod program and alternative annual examination.
              (2) The nature, number, and severity of marine casualties or accidents, as defined in § 4.03-1 of this chapter, involving the vessel in the 3 years preceding the request.
              (3) The nature, number, and gravity of any outstanding inspection requirements for the vessel.

              (4) The owner's or operator's history of compliance and cooperation in such alternative midperiod examinations and annual inspections, including:
              (i) The prompt correction of deficiencies.
              (ii) The reliability of previously submitted reports on such alternative midperiod examinations and annual inspections.
              (iii) The reliability of representations that the vessel would be, and was, employed outside of the United States during the 3 months before and after each anniversary date.
              (c) This OCMI provides the applicant with written authorization, if any, to proceed with the alternative annual inspection, including, when appropriate, special instructions.
              (d) The following conditions must be met for the alternative annual inspection to be accepted instead of the annual inspection required by § 126.510 of this subpart:
              (1) The alternative annual inspection must occur within the 3 months before or after each anniversary date.
              (2) The alternative annual inspection must be of the scope detailed by § 126.510(a) of this subchapter and must be conducted by the master, owner or operator of the vessel, or by a designated representative of the owner or operator.
              (3) Upon completion of the alternative annual inspection, the person or persons making the examination must prepare a comprehensive report describing the conditions found. This report must contain sufficient detail to let the OCMI determine whether the vessel is fit for the service and route specified on the Certificate of Inspection. This report must include all reports and receipts documenting the servicing of lifesaving equipment and any photographs or sketches necessary to clarify unusual circumstances. Each person preparing this report must sign it and certify that the information contained therein is complete and accurate.
              (4) Unless the master of the vessel participated in the alternative annual inspection and the preparation of the comprehensive report, the master will review the report for completeness and accuracy. The master must sign the report to indicate his or her review and validation and must forward it to the owner or operator of the vessel.
              (5) The owner or operator of a vessel examined under this section must review and submit the comprehensive report, required by paragraph (d)(3) of this section, to the OCMI. The report must reach the OCMI before the first day of the fifth month following the anniversary date. The forwarding letter or endorsement must be certified to be true and must contain the following information:
              (i) That the person or persons who made the alternative annual inspection acted on behalf of the vessel's owner or operator.
              (ii) That the report was reviewed by the owner or operator.
              (iii) That the discrepancies noted during the reinspection have been corrected, or will be within a stated time.
              (iv) That the owner or operator has sufficient personal knowledge of conditions aboard the vessel at the time of the reinspection, or has conducted inquires necessary to justify forming a belief that the report is complete and accurate.

              (e) The form of certification required under this section, for the alternative annual inspection, is as follows:

                I certify that to the best of my knowledge and belief the information contained in the report is complete and accurate.

              (f) Deficiencies and hazards discovered during the alternative annual inspection conducted pursuant to this section must be corrected or eliminated, if practical, before the examination report is submitted to the OCMI in accordance with paragraph (d)(5) of this section. Deficiencies and hazards that are not corrected or eliminated by the time the examination report is submitted must be listed in the report as “outstanding.” Upon receipt of an examination report indicating outstanding deficiencies or hazards, the OCMI must inform the owner or operator in writing of the time period within which to correct or eliminate the deficiencies or hazards and the method for establishing that the corrections have been accomplished. Where a deficiency or hazard remains uncorrected or uneliminated after the expiration of the time specified for correction or elimination, the Officer in Charge, Marine Inspection must initiate appropriate enforcement measures.
              (g) Upon receipt of the report, the OCMI will evaluate it and determine the following:
              (1) Whether the cognizant OCMI accepts the alternative annual inspection instead of the annual inspection required by § 126.510(a) of this subpart.
              (2) Whether the vessel is in satisfactory condition.
              (3) Whether the vessel continues to be reasonably fit for its intended service and route.
              (h) The OCMI may require further information necessary for the determinations required by this section. The OCMI will inform the owner or operator in writing of these determinations.
              (i) If the OCMI, in compliance with paragraph (g) of this section, does not accept the alternative annual inspection instead of the annual inspection required by § 126.510(a) of this subpart, he or she will require reinspection of the vessel as soon as practicable. He or she will inform the vessel owner or operator in writing that the alternative examination is not acceptable and that a reinspection is necessary. The owner, master, or operator must make the vessel available for the reinspection at a time and place agreeable to this OCMI.
              (j) If the OCMI determines, in accordance with paragraph (g) of this section, that the alternative annual inspection is accepted in lieu of the annual inspection required by § 126.510(a) of this subpart, the master must complete the applicable COI endorsement.

              (1) An alarm that—
              (i) Is dedicated for this purpose;

              (ii) Sounds in the crew accommodations and the normally manned spaces; and
              (iii) Is operable from the pilothouse; or
              (2) A telephone operated from the pilothouse that reaches the master's stateroom, engineer's stateroom, engine room, and crew accommodations that either—
              (i) Is a sound-powered telephone; or
              (ii) Gets its power from the emergency switchboard or from an independent battery continuously charged by its own charger.

              § 130.450
              Machinery alarms.
              (a) Each alarm required by § 130.460 of this subpart must be of the self-monitoring type that will both show visibly and sound audibly upon an opening or break in the sensing circuit.
              (b) The visible alarm must show until it is manually acknowledged and the condition is corrected.
              (c) The audible alarm must sound until it is manually silenced.
              (d) No silenced alarm may prevent any other audible alarm from sounding.
              (e) Each OSV must be provided with means for testing each visible and audible alarm.
              (f) Each OSV must provide battery power for the alarm required by § 130.460(a)(8) of this subpart.

              § 130.460
              Placement of machinery alarms.

              (6) Offshore workers don immersion suits (if required aboard) or lifejackets if the going becomes very rough, if the vessel is about to cross a hazardous bar, if flooding begins, or when ordered to by the master.
              (7) Never abandon the vessel unless actually forced to, or ordered to by the master.
              (8) Prepare survival craft—life floats, (inflatable) rafts, (inflatable) buoyant apparatus, and boats—for launching.
              (b) “Man overboard”. (1) Throw a ring buoy into the water as close to the person overboard as possible.
              (2) Post a lookout to keep the person overboard in sight.
              (3) Launch the rescue boat and maneuver it to pick up the person overboard, or maneuver the vessel to pick up the person.
              (4) Have a crew member put on an immersion suit or lifejacket, have a safety line made fast to the crew member, and have the crew member stand by to jump into the water to assist the person overboard if necessary.
              (5) If the person overboard is not immediately located—
              (i) Notify other vessels in the vicinity, and the Coast Guard; and
              (ii) Continue searching until released by the Coast Guard.
              (c) Fire. (1) Cut off air to the fire: close hatches, ports, doors, manual ventilators, and the like and shut off the ventilation system.
              (2) De-energize electrical systems supplying the affected compartment.
              (3) Immediately use a portable fire extinguisher aimed at the base of the flames. Never use water on electrical fires.

              (a) Except as provided by paragraph (b) of this section, ire stations must be so numerous and so placed that each part of the vessel accessible to persons aboard while the vessel is being operated, and each cargo hold, are reachable by at least two effective spray patterns of water. At least two such patterns must come from separate hydrants. At least one must come from a single length of hose.
              (b) Each part of the main machinery space, including the shaft alley if it contains space assigned for the stowage of combustibles, must be reachable by at least two streams of water. Each stream must come from a single length of hose, from a separate fire station.
              (c) Each fire station must be numbered in compliance with § 131.830 of this subchapter.
              (d) Each part of the fire main on a weather deck must be either protected against freezing or fitted with cut-out valves and drain valves so that exposed parts of the piping may be shut off and drained in freezing weather. Except when closed against freezing, the cut-out valves must be sealed open.
              (e) Each outlet at a fire hydrant must be at least 38 millimeters (11/2 inch) in diameter and, to minimize the possibility of kinking, must be fitted so that no hose leads upward from it.
              (f) Each fire station must be equipped with a spanner suitable for use on the hose there.
              (g) Each fire station must have at least one length of fire hose. Each hose on the station must have a fire nozzle approved under subpart 162.027 of this chapter that can discharge both solid stream and water spray.
              (h) Each pipe and fire hydrant must be placed so that the fire hose may be easily coupled to them. Each station must be readily accessible. No deck cargo may interfere with access to the stations; each pipe must run as far away from this cargo as practicable, to avoid risk of damage by the cargo.
              (i) Each fire hydrant or “Y” branch must be equipped with a valve such that the fire hose may be removed while there is pressure on the fire main.
              (j) Each fire hydrant connection must be of brass, bronze, or equivalent metal. The threads of fire hose couplings must be of brass or other suitable corrosion-resistant material and comply with NFPA 1963.
              (k) Each fire hydrant must have a fire hose 15.2 meters (50 feet) in length, with a minimum diameter of 38 millimeters (11/2 inches), connected to an outlet, for use at any time.
              (l) No fire hose, when part of the fire equipment, may be used for any purpose except fire-fighting, fire drills, and testing.
              (m) A suitable hose rack or other device must be provided for each fire hose. Each rack on a weather deck must be placed so as to protect its hose from heavy weather.
              (n) Each section of fire hose must be lined commercial fire hose, or lined fire hose that meets Standard 19 of Underwriters Laboratories, Inc. (UL). Hose that bears the UL label as lined fire hose complies with this section.
