Annual Survey 5 1 The owner of every United Kingdom ship in respect of which an IOPP Certificate has been issued shall, so long as the certificate remains in force, cause the ship to be subject to an annual survey, which shall be carried out within three months before or after the anniversary date of the IOPP Certificate, provided that no annual survey shall be required when the intermediate survey pursuant to regulation 6 is carried out within three months before or after the anniversary date of the IOPP Certificate. 2 The surveyor shall survey the ship in accordance with the procedures specified in Merchant Shipping Notice M 1076 and satisfy himself— a that those parts of the ship and its equipment specified in that Merchant Shipping Notice which are the subject of the survey remain efficient; and b that no material alterations have been made in the structure, equipment, systems, fittings, arrangements and materials to which the IOPP Certificate relates without the approval of the Secretary of State. 3 On completion of the survey the surveyor shall, if it is in order to do so, endorse the IOPP Certificate to that effect. Intermediate Survey 6 1 The owner of every United Kingdom ship in respect of which an IOPP Certificate has been issued shall, so long as the Certificate remains in force, cause the ship to be subject to an intermediate survey during the period of validity of the Certificate. This intermediate survey shall be held not earlier than six months before and not later than six months after the half-way date of the period of validity of the Certificate. 2 The surveyor shall survey the ship in accordance with the procedures specified in Merchant Shipping Notice M. 1076 and satisfy himself— a that those parts of the ship and its equipment specified in that Merchant Shipping Notice which are the subject of the survey are in good working order and fully comply with these regulations; b that no material alterations have been made in the structure, equipment, systems, fittings, arrangements and material to which the IOPP Certificate relates without the approval of the Secretary of State. 3 On completion of the survey, the surveyor shall, if it is in order to do so, endorse the IOPP Certificate to that effect. Issue and duration of Certificate 7 1 When it is in order to do so the Secretary of State, or as the case may be a Certifying Authority, shall issue to the ship an appropriate Certificate which— a in the case of an oil tanker of 150 GT and above and any other ship of 400 GT and above which is engaged in voyages to ports or offshore terminals under the jurisdiction of other Parties to the Convention, is an IOPP Certificate; and b in the case of any other oil tanker of 150 GT and above and any other ship of 400 GT and above, is a UKOPP Certificate. 2 The Secretary of State may request through a proper officer or otherwise, the Government of a Convention country to survey a United Kingdom ship and, if satisfied that the provisions of the Convention are complied with, to issue or authorise the issue of an IOPP Certificate to the ship. 3 A Certificate so issued shall contain a statement that it has been issued in accordance with such a request, and it shall have the same effect as a Certificate issued under paragraph (1). 4 The Secretary of State may at the request of a Government of a Convention country survey a ship registered in that State and if satisfied that the provisions of the Convention are complied with, issue an IOPP Certificate to that ship; a Certificate issued in accordance with such a request shall contain a statement that it has been so issued and shall have the same effect as if it was issued by that Government and not by the Secretary of State. 5 a The IOPP Certificate for ships other than oil tankers and the IOPP Certificate for oil tankers shall be in the form prescribed by the Convention. The UKOPP Certificate for Ships other than oil tankers and the UKOPP Certificate for oil tankers shall be in a form prescribed by the Secretary of State. These Certificates shall be valid for a period not exceeding five years from the date of issue. b The Certificates referred to in the subparagraph (a) above shall be supplemented by a Record of Construction and Equipment in the case of an international certificate in the form prescribed by the Convention, and in the case of a United Kingdom certificate in the form prescribed by the Secretary of State. 6 A Certificate shall cease to be valid— a if without the approval of the Secretary of State or, as the case may be, a Certifying Authority significant alteration has been made to the construction, equipment, systems, fitting arrangements or material required by the Regulations, other than the direct replacement of such equipment or fittings; b in the case of an IOPP Certificate, if the intermediate survey is not carried out within the period specified in regulation 6; or c when the ship transfers to the flag of another State. 7 The appropriate Certificate shall be kept on board every United Kingdom ship which is either an oil tanker of 150 GT or above or any other ship of 400 GT or above, and shall be available for inspection at all reasonable times. Responsibilities of owner and master 8 1 The owner and master of every ship shall each ensure that— a the condition of the ship and its equipment is maintained so as to comply with the relevant provisions of these Regulations; and b after any survey of a United Kingdom ship required by these Regulations has been completed, no material change is made in the structure, equipment, systems, fittings, arrangements or material subject to such survey without the approval of the Secretary of State. 2 Whenever an accident occurs to a United Kingdom ship or a defect is discovered, either of which affects the integrity of a ship or the efficiency or completeness of its equipment— i the master or (if the master fails to do so) the owner shall report it at the earliest opportunity to the Secretary of State or a Proper Officer, either of whom may cause investigations to be initiated to determine whether a survey by a surveyor is necessary and who may in that event require such a survey to be carried out; and ii if the ship is in a port of a Convention country (other than the United Kingdom) the master or (if the master fails to do so) the owner shall in addition make such a report immediately to the appropriate authorities of the country in which the port is situated. 3 a If an accident has occurred to or a defect has been discovered in or on any ship of a country (other than the United Kingdom) and which is for the time being in a United Kingdom port, and the accident or defect is such as to affect the integrity of the ship or the efficiency or completeness of its equipment, the owner or (if he fails to do so) the master shall make a report immediately to the Secretary of State and to the authority responsible for issuing the IOPP Certificate to the ship; b The owner or (if he fails to do so) the master shall report the results of any investigation or survey initiated by the authority responsible for issuing the IOPP Certificate to the ship to the Secretary of State, who may cause the ship to be detained until such a report has been made. c If within a reasonable period the Secretary of State is not satisfied that a full and proper report has been made to the authority responsible for issuing an IOPP Certficate to the ship, or that the action taken is not sufficient to restore the integrity of the ship or the efficiency or completeness of its equipment, he may take such steps as will ensure that the ship shall not sail until it can proceed to sea without presenting an unreasonable threat of harm to the marine environment. Without prejudice to any other action he may take, the Secretary of State may request the authority responsible for issuing the IOPP Certificate to the ship to carry out such surveys and inspections as it may consider to be necessary to establish that the condition of the ship is such that it can proceed to sea without presenting an unreasonable threat of harm to the marine environment. Procedure to be adopted when corrective action is necessary 9 1 In any case where the Certifying Authority determines that the condition of a United Kingdom ship or its equipment does not correspond with the particulars of the IOPP or UKOPP Certificate or is such that the ship is not fit to proceed to sea without presenting an unreasonable threat of harm to the marine environment, the Certifying Authority shall advise the owner or master of the corrective action which in its opinion is required, and shall give notice thereof to the Secretary of State. 2 If such corrective action is not taken within such period (being a reasonable period) as the Certifying Authority may specify, the Certifying Authority shall, at the end of that time, immediately notify the Secretary of State who may, on receipt of such notification, suspend the validity of the IOPP or UKOPP certificate issued to the ship and shall give notice of any such suspension to the owner and to the Certifying Authority. 3 The master shall thereupon deliver up the Certificate issued to the Certifying Authority on demand. 4 Where the ship is in a port of a Convention country (other than the United Kingdom) and corrective action in accordance with paragraph (1) has not been taken, the Certifying Authority shall in addition immediately notify the appropriate authorities of the country in which the port is situated. 5 Where, in the case of a ship of a Convention country (other than the United Kingdom) which is for the time being in a United Kingdom port, the nominated surveyor or the recognised organisation responsible for issuing the IOPP Certificate to the ship determines that it is necessary to withdraw the certificate, a report shall, unless made by the nominated surveyor or recognised organisation, be made by the master of the ship to the Secretary of State. The Secretary of State may then take such steps as will ensure that the ship shall not sail until it can proceed to sea or leave the port for the purposes of proceeding to the nearest appropriate repair yard available without presenting an unreasonable threat of harm to the marine environment. Oil Record Book 10 1 Every ship of 400 GT and above, other than an oil tanker, and every oil tanker of 150 GT and above shall be provided with an Oil Record Book, Part I (Machinery Space Operations). Every oil tanker of 150 GT and above shall also be provided with an Oil Record Book, Part II (Cargo/Ballast Operations). The Oil Record Book shall be in the form prescribed in the Convention. 2 The Oil Record Book shall be completed on each occasion, on a tank-to-tank basis if appropriate, whenever any of the following operations take place in the ship— a for machinery space operations (all ships)— i ballasting or cleaning of oil fuel tanks; ii discharging ballast or cleaning water from oil fuel tanks; iii disposing oily residues (sludge); iv discharging overboard bilge water which has accumulated in machinery spaces; b for cargo/ballast operation (oil tankers)— i loading oil cargo; ii internal transfer of oil cargo during voyage; iii unloading oil cargo; iv ballasting cargo tanks and dedicated clean ballast tanks; v cleaning cargo tanks including crude oil washing; vi discharging ballast except from segregated ballast tanks; vii discharging water from slop tanks; viii closing, after the discharge of the contents of the slop tanks, all valves or similar devices opened to permit such operations; ix closing those valves necessary for the isolation of dedicated clean ballast tanks from cargo and stripping lines after slop tank discharge operations; and x disposing residues. 3 In the event of a discharge of oil or oily mixture as is referred to in regulation 11 or in the event of an accidental or other exceptional discharge of oil not excepted by that regulation, a statement shall be made in the Oil Record Book of the circumstances of, and the reasons for, the discharge. 4 Each operation described in paragraph (2) shall be fully recorded without delay in the Oil Record Book so that all entries in the book appropriate to that operation are completed. Each completed operation shall be signed by the officer or officers in charge of the operations concerned and each completed page shall be signed by the master. 5 The Oil Record Book shall be kept in such a place as to be readily available for inspection at all reasonable times and, except in the case of unmanned ships under tow, shall be kept on board. It shall be preserved for a period of three years after the last entry has been made. 6 The Secretary of State or a person authorised by the Certifying Authority may inspect the Oil Record Book on board whilst the ship is in a port or offshore terminal and may make a copy of any entry in that book and may require the master of the ship to certify that the copy is a true copy of such an entry. Any such copy shall be admissible in any judicial proceedings as evidence of the facts stated in the entry. The inspection of an Oil Record Book and the taking of a certified copy by the Secretary of State, or a person so authorised, under this paragraph shall be performed as expeditiously as possible without causing the ship to be unduly delayed.

However, in segregated ballast oil tankers as defined in regulation 18 the permitted volume of a wing cargo oil tank situated between two segregated ballast tanks, each exceeding L c in length may be increased to the maximum limit of hypothetical oil outflow provided that the width of the wing tanks exceeds t c , where t c is defined in Schedule 4 in Merchant Shipping Notice No. 1643/MARPOL 1. 4 The length of each cargo tank shall not exceed 10 metres or one of the following values, whichever is the greater— a where no longitudinal bulkhead is provided inside the cargo tanks, the lesser of— i ( 0.5 b i B + 0.1 ) L ; and ii 0.2L; b where a centreline longitudinal bulkhead is provided inside the cargo tanks— ( 0.25 b i B + 0.15 ) L ; c where two or more longitudinal bulkheads are provided inside the cargo tanks— i for wing cargo tanks— 0.2L; ii for centre cargo tanks— A if b i B is equal to or greater than one fifth— 0.2L; B if b i B is less than one fifth— where no centreline longitudinal bulkhead is provided— (0.5 ( 0.5 b i B is + 0.1 ) L where a centreline longitudinal bulkhead is provided— (0.25 ( 0.25 b i B + 0.15 ) L ; and in this paragraph “b i ” is the minimum distance from the ship’s side to the outer longitudinal bulkhead of the tank in question measured inboard at right angles to the centreline at the level corresponding to the assigned summer freeboard. 5 In order not to exceed the volume limits established by paragraphs (2), (3) and (4) and irrespective of the type of cargo transfer system installed, when such a system inter-connects two or more cargo tanks, valves or other similar closing devices shall be provided for separating the tanks from each other. These valves or devices shall be closed when the tanker is at sea. 6 Lines of piping which run through cargo tanks in a position less than t c from the ship’s side or less than V s from the ships bottom, where V s is defined in Merchant Shipping Notice No. 1643/MARPOL 1, shall be fitted with valves or similar closing devices at the point at which they open into any cargo tank. These valves shall be kept closed at sea at any time when the tanks contain cargo oil, except that they may be opened for cargo transfer needed for the purpose of trimming of the ship. Subdivision and stability 29 1 Every new oil tanker shall comply with the subdivision and damage stability criteria specified in Schedule 5, in Merchant Shipping Notice No. 1643/MARPOL 1. 2 The master of every new oil tanker and the person in charge of a new non-self propelled oil tanker to which these Regulations apply shall be supplied by the owner with— a information relating to loading and distribution of cargo necessary to ensure compliance with the provision of this regulation; and b data on the ability of the ship to comply with the damage stability criteria prescribed by this regulation, including the effect of any lesser requirements that may have been imposed by the Secretary of State. Such information and data shall be supplied in an approved form. PART VI IMPROVED REQUIREMENTS FOR THE DESIGN AND CONSTRUCTION OF OIL TANKERS AGAINST OIL POLLUTION IN THE EVENT OF COLLISION OR STRANDING “New” oil tankers (building contracts after 5th July 1993) 30 1 This regulation applies to oil tankers of 600 tons deadweight and above— a for which the building contract is placed on or after 6th July 1993; or b in the absence of a building contract, the keel of which is laid or which is at a similar stage of construction on or after 6th January 1994; or c the delivery of which is on or after 6th July 1996; or d which has undergone a major conversion— i for which the contract is placed after 6th July 1993; or ii in the absence of a contract, the construction work of which is begun after 6th January 1994; or iii which is completed after 6th July 1996. 2 Subject to paragraphs (4) and (5), every oil tanker of 5,000 tons deadweight and above shall comply with the requirements of paragraph (3) and, in the case of an oil tanker in respect of which regulation 19 makes provision, compliance with the requirements of paragraph (3) shall be instead of compliance with the requirements of that regulation. 3 The entire cargo tank length shall be protected by ballast tanks or spaces other than cargo and fuel oil tanks, in accordance with the requirements set out in Schedule 6 in Merchant Shipping Notice No. 1643/MARPOL 1. 4 Double bottom tanks or spaces as required by paragraph (3) may be dispensed with, if the design of the tanker meets the conditions set out in Schedule 7 in Merchant Shipping Notice No. 1643/MARPOL 1. 5 Instead of complying with the requirements of paragraph (3) or (4), an oil tanker referred to in paragraph (2) may conform to other methods of design and construction, provided that such methods— a ensure at least the same level of protection against oil pollution in the event of collision or stranding; and b have the approval of the Secretary of State based on guidelines developed by the Organisation. 6 In an oil tanker to which this regulation applies, oil shall not be carried in any space extending forward of a collision bulkhead provided in accordance with regulation 3 in the Merchant Shipping (Cargo Ship Construction and Survey) Regulations 1984 . An oil tanker which is not required to have a collision bulkhead in accordance with the said regulation 3 shall not carry oil in any space extending forward of the transverse plane perpendicular to the centreline that is located as if it were a collision bulkhead provided in accordance with that regulation. 7 In approving the design and construction of an oil tanker to which this regulation applies, the Certifying Authority shall have due regard to general safety considerations (including the need for the maintenance of and for inspections of wing and double bottom tanks or spaces). “Existing” oil Tankers (building contracts before 6th July 1993) 31 1 Subject to paragraphs (2) and (3), this regulation applies to every crude oil tanker of 20,000 tons deadweight and above and to every product carrier of 30,000 tons deadweight and above— a for which the building contract was placed before 6th July 1993; or b in the absence of a building contract, the keel of which is laid or which is at a similar stage of construction before 6th January 1994; or c the delivery of which was before 6th July 1996. 2 This regulation does not apply (or, having applied, shall cease to apply) to a crude oil tanker or product carrier which has undergone a major conversion— a for which the contract is placed after 6th July 1993; or b in the absence of a contract, the construction work of which is begun after 6th January 1994; or c which is completed after 6th July 1996. 3 This regulation does not apply (or, having applied, shall cease to apply) to an oil tanker which, although not required to comply with the requirements of regulation 30,— a does in fact comply with— i the requirements of Schedule 6 in Merchant Shipping Notice 1643/MARPOL 1; or ii those requirements as modified in accordance with Schedule 7 in Merchant Shipping Notice 1643/MARPOL 1; or b conforms to other methods of design and construction which satisfy the requirements of regulation 30(5); and, for the purposes of this regulation, an oil tanker which does not meet in all respects the requirements mentioned in sub-paragraph (a) or (b) as regards minimum distances between the cargo tank boundaries and the ship side and bottom plating shall be treated as meeting those requirements if— A the side protection distance is not less than that which the IBC Code specifies for Type 2 cargo tank location (that is to say, the said distance is nowhere less than 760mm from the shell plating); and B the bottom protection distance is not less than the lesser of B/15 and 2 metres. In subparagraph (A) above, “IBC Code” means the International Code for the Construction and Equipment of Ships Carrying Dangerous Chemicals in Bulk (1994 Edition) published by the Organization and includes any document amending it which is considered relevant by the Secretary of State and is specified in a Merchant Shipping Notice. 4 a An oil tanker to which this regulation applies— i if it is a United Kingdom ship, shall be subject to an enhanced programme of inspections during renewal, annual, and intermediate surveys conducted pursuant to regulations 4, 5 and 6; ii if it is not a United Kingdom ship, shall have undergone periodical, intermediate and annual surveys as provided for by the Convention; and the scope of such surveys shall at least comply (if the tanker is a United Kingdom ship) or have complied (if the tanker is not a United Kingdom ship) with guidelines developed by the Organization pursuant to regulation 13G(3)(a) of the Convention. b An oil tanker to which this regulation applies and which is over five years of age shall carry on board a complete file containing the reports or copies of the reports on surveys of the ship carried out pursuant to— i the requirements of these Regulations (if the tanker is a United Kingdom ship); ii the requirements of the Convention (if the tanker is not a United Kingdom ship); and the file shall contain the results of all scantling measurement required and a statement of all structural work carried out and shall be available for inspection— A if the tanker is a United Kingdom ship, by the Certifying Authority, or by the competent authority of the Government of any State (other than the United Kingdom) which is a party to the Convention; B if the tanker is not a United Kingdom ship, by a Certifying Authority. c The file shall be accompanied by a condition evaluation report containing conclusions on the structural condition of the ship and its residual scantlings, and endorsed to indicate that it is considered satisfactory— i if the tanker is a United Kingdom ship, by the Certifying Authority; ii if the tanker is not a United Kingdom ship, by or on behalf of the Government of the State whose flag the ship is entitled to fly. d The file and condition evaluation reports shall be prepared in a standard format in accordance with guidelines developed by the Organization pursuant to the said regulation 13G(3)(a) of the Convention. 5 a Subject to paragraph (b), an oil tanker— i which is not a new oil tanker as defined in regulation 17(1); and ii to which this regulation still applies immediately before the expiration of 25 years from the date on which it was delivered; shall on the expiration of that period become subject to the provisions of regulation 30(5), (6) and (7), subparagraphs 1.1 to 1.7 of Schedule 6 and Schedule 7 in Merchant Shipping Notice No. 1643/MARPOL 1, and this regulation shall cease to apply to it. b The tanker shall not become subject to the provisions referred to in subparagraph (a) above (and this regulation shall not cease to apply to it) until the expiration of 30 years from the date on which it is delivered if on the expiration of 25 years from that date wing tanks or double bottom spaces, not used for the carriage of oil and meeting the width and height requirements of paragraph 3 of Schedule 1 in Merchant Shipping Notice 1643/MARPOL 1, cover— i at least 30% of L t for the full depth of the ship on each side; or ii at least 30% of the projected bottom shell area within the length L t ; where L t is as defined in paragraph 1 of Schedule 1 in Merchant Shipping Notice No. 1643/MARPOL 1. 6 An oil tanker— a which is a new oil tanker as defined in regulation 17(1); and b to which this regulation applies immediately before the expiration of 30 years from the date on which it was delivered; shall on the expiration of that period become subject to the provisions of regulations 30(5), (6) and (7), subparagraph 1.1 to 1.7 of Schedule 6 and Schedule 7 in Merchant Shipping Notice No. 1643/MARPOL 1 and this regulation shall cease to apply to it. 7 Any new ballast and load conditions resulting from the application of paragraph (5) shall, where the oil tanker is a United Kingdom ship, be subject to the approval of the Certifying Authority, and the Certifying Authority shall have particular regard to the longitudinal and local strength, intact stability and, if applicable, damage stability. 8 Other structural or operational arrangements may be accepted as alternatives to the requirements of paragraph (5) if the alternative arrangements ensure at least the same level of protection against oil pollution in the event of collision or stranding and have the approval of the Secretary of State (in the case of a United Kingdom ship) or of the Government of the State whose flag the ship is entitled to fly (in the case of a ship other than a United Kingdom ship) based on guidelines developed by the Organization pursuant to regulation 13G(7) of the Convention. PART VII OFFSHORE INSTALLATIONS Requirements for Offshore Installations 32 1 Offshore installations, when engaged in the exploration, exploitation and associated offshore processing of sea bed mineral resources, shall comply with the requirements of these Regulations applicable to ships of 400 GT and above other than oil tankers, notwithstanding that the installations are not proceeding on a voyage, except that— a they shall be equipped as far as practicable with the systems and tanks required by regulations 14 and 25(1) and (2); b they shall keep a record of all operations involving oil or oily mixture discharges, in an approved form. 2 Unless the discharge is one specified in regulation 11, an offshore installation when so engaged shall not discharge into the sea any oil or oily mixture with an oil content of 15ppm or more. 3 For the purpose of this regulation— a “offshore installation” means any mobile or fixed drilling or production platform or any other platform used in connection with the exploration, exploitation or associated offshore processing of sea bed mineral resources; b “oil or oily mixtures” means discharge associated with platform drainage and does not include production or displacement water discharge. PART VIII PREVENTION OF POLLUTION ARISING FROM AN OIL POLLUTION INCIDENT Shipboard oil pollution emergency plan 33 1 Every oil tanker of 150 GT and above and every ship (not being an oil tanker) of 400 GT and above shall carry on board an approved shipboard oil pollution emergency plan. 2 The plan shall be in accordance with the guidelines for the development of shipboard oil pollution emergency plans adopted by the Marine Environment Protection Committee of the Organization on 6th March 1992 by Resolution MEPC 54(32) and includes any document amending it which is considered by the Secretary of State to be relevant from time to time and is specified in a Merchant Shipping Notice; and the plan shall include at least— i the procedure to be followed by the master or other persons having charge of the ship to report an oil pollution incident as required by the Merchant Shipping (Reporting Requirements for Ships Carrying Dangerous or Polluting Goods) Regulations 1995 ; ii the list of persons (including national and local authorities) to be contacted in the event of an oil pollution incident; iii a detailed description of the action to be taken immediately by persons on board to reduce or control the discharge of oil following an incident; and iv the procedures and point of contact on the ship for co-ordinating shipboard action with national and local authorities in combating the pollution. PART IX POWERS TO INSPECT, DENY ENTRY, DETENTION AND PENALTIES Power to Inspect 34 1 a A ship to which these Regulations apply shall be subject, in any United Kingdom port or offshore terminal, to inspections by persons appointed by the Secretary of State. b Any such inspection shall be limited to verifying that there is on board a valid IOPP Certificate in the form prescribed by the Convention or a UKOPP Certificate in a form prescribed by the Secretary of State, unless there are clear grounds for believing that the condition of the ship or its equipment does not correspond substantially with the particulars of that Certificate. In that case, or if the ship does not carry a valid certificate, the inspector shall take such steps as he may consider necessary to ensure that the ship shall not sail until it can proceed to sea without presenting an unreasonable threat of harm to the marine environment. The Secretary of State may in such a case permit the ship to leave the port or offshore terminal for the purposes of proceeding to the nearest appropriate repair yard. c Notwithstanding subparagraph (b) above, and without prejudice to any specific control provisions over operational procedures provided for in these Regulations, the inspector may investigate any operation regulated by these Regulations if there are clear grounds for believing that the master or crew are not familiar with essential ship board procedures for preventing pollution by oil. In the event of any such inspection revealing deficiencies the Inspector shall take such steps as to ensure that the ship will not sail until the situation has been brought to order in accordance with the requirements of these Regulations. 2 Upon receiving evidence that a particular ship has discharged oil or an oily mixture contrary to the provisions of these Regulations the Secretary of State shall cause the matter to be investigated and shall inform the State which has reported the contravention, as well as the International Maritime Organisation, of the action taken. 3 For the purposes of this regulation any person appointed as an inspector shall have the powers of an inspector set out in sections 259 and 260 of the Merchant Shipping Act 1995. Power to deny entry or detain 35 1 If a harbour master has reason to believe that a ship which he believes proposes to enter the harbour does not comply with the requirements of these Regulations, he shall immediately report the matter to the Secretary of State who, if he is satisfied that the ship presents an unreasonable threat of harm to the marine environment, may deny the entry of such ship to United Kingdom ports or offshore terminals. 2 a In any case where a ship to which these Regulations apply is suspected of a contravention of the requirements of these Regulations, the ship shall be liable to be detained. b Where the steps taken by an inspector under regulation 34(1)(b) or (c) involve detention of the ship, or in the event of detention under this regulation, then section 284 of the Merchant Shipping Act 1995 (which relates to the detention of a ship) shall have effect in relation to the ship, subject to the modifications that as if the words “this Act” wherever they appear, there were substituted “the Merchant Shipping (Prevention of Oil Pollution) Regulations 1996”. 3 Where a ship other than a United Kingdom ship is— a denied entry pursuant to paragraph (1); or b detained pursuant to paragraph (2); or c detained pursuant to regulation 37(3); the Secretary of State shall immediately inform the consul or diplomatic representative of the State whose flag the ship is entitled to fly or the appropriate maritime authorities of that State. Penalties 36 1 If any ship fails to comply with any requirement of these Regulations (other than regulations 12, 13 and 16) the owner and the master of the ship shall each be guilty of an offence and punishable on summary conviction by a fine not exceeding the statutory maximum and on conviction on indictment by a fine. 2 If any ship fails to comply with any requirement of regulation 12, 13 or 16, the owner and the master shall each be guilty of an offence and section 131(3) of the Merchant Shipping Act 1995 shall apply as it applies to an offence under that section, so that each of the owner and the master shall be liable on summary conviction to a fine not exceeding £50,000 or on conviction on indictment to a fine. 3 It shall be a defence for a person charged under paragraph (1) of this regulation to show that he took all reasonable precautions and exercised all due diligence to avoid the commission of the offence. 4 Where an offence under this regulation is committed, or would have been committed save for the operation of paragraph (3), by any person due to the act or default of some other person, that other person shall be guilty of the offence, and a person may be charged with and convicted of an offence by virtue of this paragraph whether or not proceedings are taken against the first-mentioned person. Enforcement and application of fines 37 1 Any document required or authorised, by virtue of any statutory provision, to be served on a foreign company for the purposes of the institution of or otherwise in connection with, proceedings for an offence of contravening regulation 12, 13 or 16 alleged to have been committed by the company as the owner of a ship shall be treated as duly served on that company if the document is served on the master of the ship; and any person authorised to serve any document for the purposes of the institution of, or otherwise in connection with proceedings for an offence under these Regulations (whether or not in pursuance of the foregoing provisions of this paragraph) shall, for that purpose, have the right to go on board the ship in question. 2 In paragraph (1), a “foreign company” means a company or body which is not one to whom any of the following provisions applies— a section 695 and 725 of the Companies Act 1985 ;

b such proceedings, having been instituted through exercise of the power conferred by paragraph (1) within that period, are concluded without the master or owner being convicted; c either— i the sum of £55,000 is paid to the Secretary of State by way of security; or ii security which, in the opinion of the Secretary of State, is satisfactory and is for an amount not less than £55,000 is given to the Secretary of State, by or on behalf of the master or owner; or d where the master or owner is convicted of the offence, any costs or expenses ordered to be paid by him, and any fine imposed on him, have been paid, or; e the release is ordered by a court or tribunal referred to in Article 292 of the United Nations Convention on the Law of the Sea 1982, and any bond or other financial security ordered by such a court or tribunal is posted. 4 The Secretary of State shall repay any sum paid in pursuance of paragraph (3)(c) or release any security so given— a if no proceedings for the offence in question are instituted within the period of 7 days beginning with the day on which the sum is paid; or b if such proceedings, having been instituted within that period are concluded without the master or owner being convicted. 5 Where a sum has been paid, or security has been given, by any person in pursuance of paragraph (3)(c) and the master or owner is convicted of the offence in question, the sum so paid or the amount made available under the security shall be applied as follows— a first in payment of any costs or expenses ordered by the court to be paid by the master or owner; and b next in payment of any fine imposed by the court; and any balance shall be repaid to the person paying the sum, or giving the security. 6 For the purposes of this regulation in its application to England and Wales and subject to paragraph (8) in its application to Northern Ireland— a proceedings for an offence are instituted— i when a justice of the peace issues a summons or warrant under section 1 of the Magistrates' Courts Act 1980 in respect of the offence, ii when a person is charged with the offence after being taken into custody without a warrant, iii when a bill of indictment is preferred by virtue of section 2(2)(b) of the Administration of Justice (Miscellaneous Provisions) Act 1933 ; and where the application of this paragraph would result in their being more than one time for the institution of proceedings, they shall be taken to have been instituted at the earliest of those times; and b proceedings for an offence are concluded without the master or owner being convicted on the occurrence of one of the following events— i the discontinuance of the proceedings; ii the acquittal of the master or owner; iii the quashing of the master or owner’s conviction for the offence; iv the grant of Her Majesty’s pardon in respect of the master or owner’s conviction for the offence. 7 For the purposes of this regulation in its application to Scotland— a proceedings for an offence are instituted— i on the granting by the sheriff of a warrant in respect of the offence on presentation of a petition under section 12 of the Criminal Procedure (Scotland) Act 1975 ; ii when, in the absence of a warrant or citation, the master or owner is first brought before a court competent to deal with the case; iii when, in the case where he is liberated upon a written undertaking in terms of section 18(2)(a), 294(2)(a) or 295(1)(a) of the Criminal Procedure (Scotland) Act 1975, the master or owner appears at the specified court at the specified time; iv when, in a case mentioned in paragraph (iii) above where the master or owner fails to appear at the specified court at the specified time, the court grants warrant for his apprehension; v when summary proceedings are commenced in terms of section 33 1(3) of the Criminal Procedure (Scotland) Act 1975; and b proceedings for an offence are concluded without the master or owner being convicted on the occurrence of one of the following events— i the court pronounces a verdict of not guilty or not proven against the master or owner in respect of the offence; ii the proceedings are expressly abandoned (other than pro loco et tempore) by the prosecutor or are deserted simpliciter; iii the conviction is quashed; iv the accused receives Her Majesty’s pardon in respect of the conviction. 8 In its application to proceedings in Northern Ireland, paragraph (6)(a) above shall have effect as if— a in sub-paragraph (i), for the references to section 1 of the Magistrates' Courts Act 1980 there were substituted a reference to Article 20 of the Magistrates' Courts (Northern Ireland) Order 1981 ; and b for sub-paragraph (iii) there were substituted— iii when an indictment is presented under section 2(2)(c), (e) or (f) of the Grand Jury (Abolition) Act (Northern Ireland) 1969 . 9 Where a fine imposed by a court in proceedings against the owner or master of a ship for an offence under regulations 12, 13 or 16 above is not paid or any costs or expenses ordered to be paid by him are not paid at the time ordered by the court, the court shall, in addition to any other powers for enforcing payment, have power to direct the amount remaining unpaid to be levied by distress or arrestment and sale of the ship, her tackle, furniture and apparel. 10 Where a person is convicted of an offence under regulations 12, 13 or 16 above, and the court imposes a fine in respect of the offence, then if it appears to the court that any person has incurred, or will incur, expenses in removing any pollution, or making good any damage, which is attributable to the offence, the court may order the whole or part of the fine to be paid to that person for or towards defraying those expenses. PART X PROCEEDINGS FOR POLLUTION OFFENCES COMMITTED OUTSIDE UK WATERS Restriction on jurisdiction over offences outside UK limits 38 1 No proceedings for an offence of contravening regulation 12, 13 or 16 by a ship which is not a United Kingdom ship, which relates to a discharge in the internal waters, territorial waters or exclusive economic zone of another State shall be instituted unless— a that State, the flag state or a State damaged or threatened by the discharge requests that proceedings be taken; or b the discharge has caused or is likely to cause pollution in the internal waters, territorial sea or controlled waters of the United Kingdom. 2 Where proceedings for an offence of contravening regulation 12, 13 or 16 by a ship which is not a United Kingdom ship which relates to a discharge in the internal waters, territorial sea or exclusive economic zone of another State have been instituted but not concluded, and that State requests suspension of the proceedings, then— a proceedings shall be suspended; and b the Secretary of State shall transmit all the evidence and court records and documents relating to the case, together with any sum paid or security given pursuant to regulation 37 (3)(c), to that State. 3 It shall be a defence to a person charged with contravening regulation 12, 13 or 16 for the defendant to show— a that the ship is not a United Kingdom ship; and b the discharge took place outside the United Kingdom, its territorial waters and the controlled waters of the United Kingdom; and c the ship was in a port in the United Kingdom at the time of institution of proceedings by reason only of stress of weather or other reason beyond the control of the master or owner or charterer. Suspension of proceedings at flag state request 39 1 This regulation relates to an alleged offence of contravening regulation 12, 13 or 16 by a ship which is not a United Kingdom ship, in relation to a discharge outside the United Kingdom or its territorial waters. 2 a Any proceedings for such an offence shall be stayed if the Court is satisfied that the flag state has instituted proceedings corresponding to the proceedings in United Kingdom in respect of the discharge, within six months of the institution of proceedings in the United Kingdom. b Subparagraph (a) above does not apply— i where the discharge resulted in major damage to the United Kingdom; or ii the Secretary of State certifies that the flag state has repeatedly disregarded its obligation to enforce effectively the requirements of the Convention in respect of its ships. 3 Where proceedings instituted by the flag state have been brought to a conclusion, the suspended proceedings shall be terminated. 4 Where the costs of the Secretary of State incurred in respects of proceedings suspended under paragraph (2) have been paid, any money paid or security given under regulation 37(3)(c) shall be released. Supplementary 40 For the purposes of regulations 38 and 39, proceedings for an offence are to be treated as being instituted in the United Kingdom in the circumstances set out in regulation 37(6), (7) or (8) as the case may be.
