Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a) Bollard Pull Testing Requirements.
(1) All escort tugs in the Los Angeles/Long
					 Beach Harbor used for escorting tank vessels, shall have their static bollard
					 pull (ahead and astern) measured for determining their forces in
					 kips.
(2) Static bollard pull
					 measurements shall be verified by a member of IACS, and in accordance with the
					 following standards:
(A) The measurement
					 shall be taken with the escort tug's trim and/or displacement corresponding to
					 applicable loadline requirements or letter of stability.
(B) Auxiliary equipment (such as pumps and
					 generators) which is driven from the main engine(s) or propeller shaft(s) in
					 normal operation of the escort tug shall be connected during the measurement
					 process.
(C) All bollard pull
					 measurements shall be derived solely on the basis of the escort tug's
					 capabilities. No outside assistance shall be allowed.
(D) The propeller(s) blades fitted during the
					 measurement shall be the same as those used when the escort tug is in normal
					 operation.
(E) Water depth shall be
					 a minimum of 45 feet (not underwater clearance).
(F) Water current shall not exceed 1.0
					 knot.
(G) Wind velocity shall not
					 exceed 10 knots.
1. Measurements of water
					 current and wind velocity shall be provided to the classification society
					 surveyor by the escort tug owner's representative.
(H) Towline length shall be a minimum of 300
					 feet.
(I) The strain cell used for
					 the measurements shall have been calibrated within the past 12 months. The
					 classification surveyor shall verify this fact. The accuracy of the strain cell
					 shall be +/-2% within a temperature range of -40° and 104°F.
(J) Instruments providing both a continuous
					 read-out and the bollard pull graphically as a function of the time, shall be
					 connected to the strain cell.
(K)
					 The surveyor for the classification society shall:
1. be aboard the escort tug during the
					 measurement process to verify that the bollard pull report is
					 correct;
2. determine the escort
					 tug's static bollard pull capacity by averaging the forces recorded (without
					 any significant tendency of decline) for a period of at least 15 minutes while
					 maintaining a fixed reading with the engine(s) operating at the manufacturer's
					 recommended continuous output;
3.
					 sign the completed "BOLLARD PULL REPORT" of the Los Angeles/Long Beach Harbor
					 Safety Committee; and
4. sign and
					 issue a "BOLLARD PULL CERTIFICATE".
(3) Escort tug companies shall provide the
					 Los Angeles/Long Beach Harbor Safety Committee with the results of the static
					 bollard pull measurements taken pursuant to the provisions of this
					 subchapter.
(4) Results of any and
					 all static bollard pull measurements shall be inventoried and published by the
					 Marine Exchange.
(5) Escort tugs
					 which do not have current bollard pull certifications on file with the Marine
					 Exchange and the Harbor Safety Committee or which do not meet the requirements
					 for alternative compliance for bollard pull measurements, cannot be used for
					 the escort of tank vessels in the Los Angeles/Long Beach Harbor.
(6) The braking force shall be re-measured
					 after any modifications and/or repairs to the main engines, hull, shaft-drive
					 line, or steering, that could affect bollard pull. The new measurements must be
					 reported to the Los Angeles/Long Beach Harbor Safety Committee and on file with
					 the Marine Exchange.
(7) Any escort
					 tug used to comply with the requirements of this subchapter shall also meet one
					 of the following:
(A) the escort tug shall
					 have its braking force re-measured within 3 years of its last bollard pull
					 test, or;
(B) the escort tug shall
					 submit to an Escort Tug Inspection Program, as follows:
1. Escort tugs 150 gross tons or greater, and
					 classed escort tugs shall be made available for inspection by the Administrator
					 twice in five years during their dry dock examination. The period between
					 inspections shall not exceed three years.
2. Escort tug maintenance records shall be
					 made available for inspection by the Administrator.
3. If dry dock examination extensions are
					 necessary, escort tugs shall comply with the direction of the cognizant Officer
					 in Charge, Marine Inspection, or American Bureau of Shipping principal
					 surveyors' direction.
4. For
					 classed escort tugs, a copy of the Class Surveyor's report confirming that the
					 condition of the drive train (shafts, propellers, nozzles or other type drive)
					 and main engines are in the same state as when the builder's or last bollard
					 pull certificate was issued, shall be forwarded to the Administrator.
5. Escort tug companies shall participate and
					 have a certificate of compliance from one of the following Management Systems:
i. American Waterways Operators Responsible
					 Carrier Program;
ii. International
					 Safety Management;
iii. ISO 9000
					 (quality management).
6.
					 Escort tugs of less than 150 gross tons shall be made available for inspection
					 by the Administrator once in five years during their dry dock examination.
					 These escort tugs shall use a certified Marine Surveyor and shall comply with
					 subsections
					 2,
					 3, and
					 4, above.
(C) Escort tugs that submit to the Escort Tug
					 Inspection Program, as described above, can perform escort duties in any port
					 in the state, if the tugs meet the requirements of the appropriate subchapter
					 (i.e., Subchapter 1, San Francisco Bay Region; Subchapter 2, Los Angeles/Long
					 Beach Harbor; Subchapter 3, Port Hueneme Harbor; Subchapter 4, Humboldt Bay;
					 Subchapter 5, San Diego Harbor), of this Chapter 4 of the California Code of
					 Regulations.
