With respect to a ship entitled to fly a flag of any State, the Administration is the Government of that State. With respect to fixed or floating platforms engaged in exploration and exploitation of the sea‑bed and subsoil thereof adjacent to the coast over which the coastal State exercises sovereign rights for the purposes of exploration and exploitation of their natural resources, the Administration is the Government of the coastal State concerned.\n\n(6) “Incident” means an event involving the actual or probable discharge into the sea of a harmful substance, or effluents containing such a substance.\n\n(7) “Organization” means the Inter‑Governmental Maritime Consultative Organization.\n\nARTICLE 3\n\n(1) The present Convention shall apply to:\n\n(a) ships entitled to fly the flag of a Party to the Convention; and\n\n(b) ships not entitled to fly the flag of a Party but which operate under the authority of a Party.\n\n(2) Nothing in the present Article shall be construed as derogating from or extending the sovereign rights of the Parties under international law over the sea‑bed and subsoil thereof adjacent to their coasts for the purposes of exploration and exploitation of their natural resources.\n\n(3) The present Convention shall not apply to any warship, naval auxiliary or other ship owned or operated by a State and used, for the time being, only on government non‑commercial service. However, each Party shall ensure by the adoption of appropriate measures not impairing the operations or operational capabilities of such ships owned or operated by it, that such ships act in a manner consistent, so far as is reasonable and practicable, with the present Convention.\n\nARTICLE 4\n\n*Violation*\n\n(1) Any violation of the requirements of the present Convention shall be prohibited and sanctions shall be established therefor under the law of the Administration of the ship concerned wherever the violation occurs. If the Administration is informed of such a violation and is satisfied that sufficient evidence is available to enable proceedings to be brought in respect of the alleged violation, it shall cause such proceedings to be taken as soon as possible, in accordance with its law.\n\n(2) Any violation of the requirements of the present Convention within the jurisdiction of any Party to the Convention shall be prohibited and sanctions shall be established therefor under the law of that Party. Whenever such a violation occurs, that Party shall either:\n\n(a) cause proceedings to be taken in accordance with its law; or\n\n(b) furnish to the Administration of the ship such information and evidence as may be in its possession that a violation has occurred.\n\n(3) Where information or evidence with respect to any violation of the present Convention by a ship is furnished to the Administration of that ship, the Administration shall promptly inform the Party which has furnished the information or evidence, and the Organization, of the action taken.\n\n(4) The penalties specified under the law of a Party pursuant to the present Article shall be adequate in severity to discourage violations of the present Convention and shall be equally severe irrespective of where the violations occur.\n\nARTICLE 5\n\n*Certificates and Special Rules on Inspection of Ships*\n\n(1) Subject to the provisions of paragraph (2) of the present Article a certificate issued under the authority of a Party to the Convention in accordance with the provisions of the Regulations shall be accepted by the other Parties and regarded for all purposes covered by the present Convention as having the same validity as a certificate issued by them.\n\n(2) A ship required to hold a certificate in accordance with the provisions of the Regulations is subject, while in the ports or off‑shore terminals under the jurisdiction of a Party, to inspection by officers duly authorized by that Party. Any such inspection shall be limited to verifying that there is on board a valid certificate, 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 Party carrying out the inspection shall 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. That Party may, however, grant such a ship permission to leave the port or off‑shore terminal for the purpose of proceeding to the nearest appropriate repair yard available.\n\n(3) If a Party denies a foreign ship entry to the ports or off‑shore terminals under its jurisdiction or takes any action against such a ship for the reason that the ship does not comply with the provisions of the present Convention, the Party shall immediately inform the consul or diplomatic representative of the Party whose flag the ship is entitled to fly, or if this is not possible, the Administration of the ship concerned. Before denying entry or taking such action the Party may request consultation with the Administration of the ship concerned. Information shall also be given to the Administration when a ship does not carry a valid certificate in accordance with the provisions of the Regulations.\n\n(4) With respect to the ships of non‑Parties to the Convention, Parties shall apply the requirements of the present Convention as may be necessary to ensure that no more favourable treatment is given to such ships.\n\nARTICLE 6\n\n*Detection of Violations and Enforcement of the Convention*\n\n(1) Parties to the Convention shall co‑operate in the detection of violations and the enforcement of the provisions of the present Convention, using all appropriate and practicable measures of detection and environmental monitoring, adequate procedures for reporting and accumulation of evidence.\n\n(2) A ship to which the present Convention applies may, in any port or off‑shore terminal of a Party, be subject to inspection by officers appointed or authorized by that Party for the purpose of verifying whether the ship has discharged any harmful substances in violation of the provisions of the Regulations. If an inspection indicates a violation of the Convention, a report shall be forwarded to the Administration for any appropriate action.\n\n(3) Any Party shall furnish to the Administration evidence, if any, that the ship has discharged harmful substances or effluents containing such substances in violation of the provisions of the Regulations. If it is practicable to do so, the competent authority of the former Party shall notify the Master of the ship of the alleged violation.\n\n(4) Upon receiving such evidence, the Administration so informed shall investigate the matter, and may request the other Party to furnish further or better evidence of the alleged contravention. If the Administration is satisfied that sufficient evidence is available to enable proceedings to be brought in respect of the alleged violation, it shall cause such proceedings to be taken in accordance with its law as soon as possible. The Administration shall promptly inform the Party which has reported the alleged violation, as well as the Organization, of the action taken.\n\n(5) A Party may also inspect a ship to which the present Convention applies when it enters the ports or off‑shore terminals under its jurisdiction, if a request for an investigation is received from any Party together with sufficient evidence that the ship has discharged harmful substances or effluents containing such substances in any place. The report of such investigation shall be sent to the Party requesting it and to the Administration so that the appropriate action may be taken under the present Convention.\n\nARTICLE 7\n\n*Undue Delay to Ships*\n\n(1) All possible efforts shall be made to avoid a ship being unduly detained or delayed under Article 4, 5 or 6 of the present Convention.\n\n(2) When a ship is unduly detained or delayed under Article 4, 5 or 6 of the present Convention, it shall be entitled to compensation for any loss or damage suffered.\n\nARTICLE 8\n\n*Reports on Incidents Involving Harmful Substances*\n\n(1) A report of an incident shall be made without delay to the fullest extent possible in accordance with the provisions of Protocol I to the present Convention.\n\n(2) Each Party to the Convention shall:\n\n(a) make all arrangements necessary for an appropriate officer or agency to receive and process all reports on incidents; and\n\n(b) notify the Organization with complete details of such arrangements for circulation to other Parties and Member States of the Organization.\n\n(3) Whenever a Party receives a report under the provisions of the present Article, that Party shall relay the report without delay to:\n\n(a) the Administration of the ship involved; and\n\n(b) any other State which may be affected.\n\n(4) Each Party to the Convention undertakes to issue instructions to its maritime inspection vessels and aircraft and to other appropriate services, to report to its authorities any incident referred to in Protocol I to the present Convention. That Party shall, if it considers it appropriate, report accordingly to the Organization and to any other party concerned.\n\nARTICLE 9\n\n*Other Treaties and Interpretation*\n\n(1) Upon its entry into force, the present Convention supersedes the International Convention for the Prevention of Pollution of the Sea by Oil, 1954, as amended, as between Parties to that Convention.\n\n(2) Nothing in the present Convention shall prejudice the codification and development of the law of the sea by the United Nations Conference on the Law of the Sea convened pursuant to Resolution 2750 C (XXV) of the General Assembly of the United Nations nor the present or future claims and legal views of any State concerning the law of the sea and the nature and extent of coastal and flag State jurisdiction.\n\n(3) The term “jurisdiction” in the present Convention shall be construed in the light of international law in force at the time of application or interpretation of the present Convention.\n\nARTICLE 10\n\n*Settlement of Disputes*\n\nAny dispute between two or more Parties to the Convention concerning the interpretation or application of the present Convention shall, if settlement by negotiation between the Parties involved has not been possible, and if these Parties do not otherwise agree, be submitted upon request of any of them to arbitration as set out in Protocol II to the present Convention.\n\nARTICLE 11\n\n*Communication of Information*\n\n(1) The Parties to the Convention undertake to communicate to the Organization:\n\n(a) the text of laws, orders, decrees and regulations and other instruments which have been promulgated on the various matters within the scope of the present Convention;\n\n(b) a list of non‑governmental agencies which are authorized to act on their behalf in matters relating to the design, construction and equipment of ships carrying harmful substances in accordance with the provisions of the Regulations;\n\n(c) a sufficient number of specimens of their certificates issued under the provisions of the Regulations;\n\n(d) a list of reception facilities including their location, capacity and available facilities and other characteristics;\n\n(e) official reports or summaries of official reports in so far as they show the results of the application of the present Convention; and\n\n(f) an annual statistical report, in a form standardized by the Organization, of penalties actually imposed for infringement of the present Convention.\n\n(2) The Organization shall notify Parties of the receipt of any communications under the present Article and circulate to all Parties any information communicated to it under sub‑paragraphs (1)(b) to (f) of the present Article.\n\nARTICLE 12\n\n*Casualties to Ships*\n\n(1) Each Administration undertakes to conduct an investigation of any casualty occurring to any of its ships subject to the provisions of the Regulations if such casualty has produced a major deleterious effect upon the marine environment.\n\n(2) Each Party to the Convention undertakes to supply the organization with information concerning the findings of such investigation, when it judges that such information may assist in determining what changes in the present Convention might be desirable.\n\nARTICLE 13\n\n*Signature, Ratification, Acceptance, Approval and Accession*\n\n(1) The present Convention shall remain open for signature at the Headquarters of the Organization from 15 January 1974 until 31 December 1974 and shall thereafter remain open for accession.

In all cases, however, the capacity of segregated ballast tanks shall be at least such that in any ballast condition at any part of the voyage, including the conditions consisting of lightweight plus segregated ballast only, the ship’s draughts and trim can meet each of the following requirements:\n\n(a) the moulded draught amidships (dm) in metres (without taking into account any ship’s deformation) shall not be less than:\n\ndm = 2.0 + 0.02L;\n\n(b) the draughts at the forward and after perpendiculars shall correspond to those determined by the draught amidships (dm), as specified in sub‑paragraph (a) of this paragraph, in association with the trim by the stern of not greater than 0.015L; and\n\n(c) in any case the draught at the after perpendicular shall not be less than that which is necessary to obtain full immersion of the propeller(s).\n\n(3) In no case shall ballast water be carried in oil tanks except in weather conditions so severe that, in the opinion of the Master, it is necessary to carry additional ballast water in oil tanks for the safety of the ship. Such additional ballast water shall be processed and discharged in compliance with Regulation 9 and in accordance with the requirements of Regulation 15 of this Annex, and entry shall be made in the Oil Record Book referred to in Regulation 20 of this Annex.\n\n(4) Any oil tanker which is not required to be provided with segregated ballast tanks in accordance with paragraph (1) of this Regulation may, however, be qualified as a segregated ballast tanker, provided that in the case of an oil tanker of 150 metres in length and above it fully complies with the requirements of paragraphs (2) and (3) of this Regulation and in the case of an oil tanker of less than 150 metres in length the segregated ballast conditions shall be to the satisfaction of the Administration.\n\nRegulation 14\n\n*Segregation of Oil and Water Ballast*\n\n(1) Except as provided in paragraph (2) of this Regulation, in new ships of 4,000 tons gross tonnage and above other than oil tankers, and in new oil tankers of 150 tons gross tonnage and above, no ballast water shall be carried in any oil fuel tank.\n\n(2) Where abnormal conditions or the need to carry large quantities of oil fuel render it necessary to carry ballast water which is not a clean ballast in any oil fuel tank, such ballast water shall be discharged to reception facilities or into the sea in compliance with Regulation 9 using the equipment specified in Regulation 16(2) of this Annex, and an entry shall be made in the Oil Record Book to this effect.\n\n(3) All other ships shall comply with the requirements of paragraph (1) of this Regulation as far as reasonable and practicable.\n\nRegulation 15\n\n*Retention of Oil on Board*\n\n(1) Subject to the provisions of paragraphs (5) and (6) of this Regulation, oil tankers of 150 tons gross tonnage and above shall be provided with arrangements in accordance with the requirements of paragraphs (2) and (3) of this Regulation, provided that in the case of existing tankers the requirements for oil discharge monitoring and control systems and slop tank arrangements shall apply three years after the date of entry into force of the present Convention.\n\n(2) (a) Adequate means shall be provided for cleaning the cargo tanks and transferring the dirty ballast residue and tank washings from the cargo tanks into a slop tank approved by the Administration. In existing oil tankers, any cargo tank may be designated as a slop tank.\n\n(b) In this system arrangements shall be provided to transfer the oily waste into a slop tank or combination of slop tanks in such a way that any effluent discharged into the sea will be such as to comply with the provisions of Regulation 9 of this Annex.\n\n(c) The arrangements of the slop tank or combination of slop tanks shall have a capacity necessary to retain the slops generated by tank washing, oil residues and dirty ballast residues but the total shall be not less than 3 per cent of the oil carrying capacity of the ship, except that, where segregated ballast tanks are provided in accordance with Regulation 13 of this Annex, or where arrangements such as eductors involving the use of water additional to the washing water are not fitted, the Administration may accept 2 per cent. New oil tankers over 70,000 tons deadweight shall be provided with at least two slop tanks.\n\n(d) Slop tanks shall be so designed particularly in respect of the position of inlets, outlets, baffles or weirs where fitted, so as to avoid excessive turbulence and entrainment of oil or emulsion with the water.\n\n(3) (a) An oil discharge monitoring and control system approved by the Administration shall be fitted. In considering the design of the oil content meter to be incorporated in the system, the Administration shall have regard to the specification recommended by the Organization.[[1]](#footnote-1)* The system shall be fitted with a recording device to provide a continuous record of the discharge in litres per nautical mile and total quantity discharged, or the oil content and rate of discharge. This record shall be identifiable as to time and date and shall be kept for at least three years. The oil discharge monitor and control system shall come into operation when there is any discharge of effluent into the sea and shall be such as will ensure that any discharge of oily mixture is automatically stopped when the instantaneous rate discharge of oil exceeds that permitted by Regulation 9(1)(a) of this Annex. Any failure of this monitoring and control system shall stop the discharge and be noted in the Oil Record Book. A manually operated alternative method shall be provided and may be used in the event of such failure, but the defective unit shall be made operable before the oil tanker commences its next ballast voyage unless it is proceeding to a repair port. Existing oil tankers shall comply with all of the provisions specified above except that the stopping of the discharge may be performed manually and the rate of discharge may be estimated from the pump characteristic.\n\n(b) Effective oil/water interface detectors approved by the Administration shall be provided for a rapid and accurate determination of the oil/water interface in slop tanks and shall be available for use in other tanks where the separation of oil and water is effected and from which it is intended to discharge effluent direct to the sea.\n\n(c) Instructions as to the operation of the system shall be in accordance with an operational manual approved by the Administration. They shall cover manual as well as automatic operations and shall be intended to ensure that at no time shall oil be discharged except in compliance with the conditions specified in Regulation 9 of this Annex.[[2]](#footnote-2)**\n\n(4) The requirements of paragraphs (1), (2) and (3) of this Regulation shall not apply to oil tankers of less than 150 tons gross tonnage, for which the control of discharge of oil under Regulation 9 of this Annex shall be effected by the retention of oil on board with subsequent discharge of all contaminated washings to reception facilities. The total quantity of oil and water used for washing and returned to a storage tank shall be recorded in the Oil Record Book. This total quantity shall be discharged to reception facilities unless adequate arrangements are made to ensure that any effluent which is allowed to be discharged into the sea is effectively monitored to ensure that the provisions of Regulation 9 of this Annex are complied with.\n\n(5) The Administration may waive the requirements of paragraphs (1), (2) and (3) of this Regulation for any oil tanker which engages exclusively on voyages both of 72 hours or less in duration and within 50 miles from the nearest land, provided that the oil tanker is not required to hold and does not hold an International Oil Pollution Prevention Certificate (1973). Any such waiver shall be subject to the requirement that the oil tanker shall retain on board all oily mixtures for subsequent discharge to reception facilities and to the determination by the Administration that facilities available to receive such oily mixtures are adequate.\n\n(6) Where in the view of the Organization equipment required by Regulation 9(1)(a)(vi) of this Annex and specified in sub‑paragraph (3)(a) of this Regulation is not obtainable for the monitoring of discharge of light refined products (white oils), the Administration may waive compliance with such requirement, provided that discharge shall be permitted only in compliance with procedures established by the Organization which shall satisfy the conditions of Regulation 9(1)(a) of this Annex except the obligation to have an oil discharge monitoring and control system in operation. The Organization shall review the availability of equipment at intervals not exceeding twelve months.\n\n(7) The requirements of paragraphs (1), (2) and (3) of this Regulation shall not apply to oil tankers carrying asphalt, for which the control of discharge of asphalt under Regulation 9 of this Annex shall be effected by the retention of asphalt residues on board with discharge of all contaminated washings to reception facilities.\n\nRegulation 16\n\n*Oil Discharge Monitoring and Control System and Oily‑Water Separating Equipment*\n\n(1) Any ship of 400 tons gross tonnage and above shall be fitted with an oily‑water separating equipment or filtering system complying with the provisions of paragraph (6) of this Regulation. Any such ship which carries large quantities of oil fuel shall comply with paragraph (2) of this Regulation or paragraph (1) of Regulation 14.\n\n(2) Any ship of 10,000 tons gross tonnage and above shall be fitted:\n\n(a) in addition to the requirements of paragraph (1) of this Regulation with an oil discharge monitoring and control system complying with paragraph (5) of this Regulation; or\n\n(b) as an alternative to the requirements of paragraph (1) and sub‑paragraph (2)(a) of this Regulation, with an oily‑water separating equipment complying with paragraph (6) of this Regulation and an effective filtering system, complying with paragraph (7) of this Regulation.\n\n(3) The Administration shall ensure that ships of less than 400 tons gross tonnage are equipped, as far as practicable, to retain on board oil or oily mixtures or discharge them in accordance with the requirements of Regulation 9(1)(b) of this Annex.\n\n(4) For existing ships the requirements of paragraphs (1), (2) and (3) of this Regulation shall apply three years after the date of entry into force of the present Convention.\n\n(5) An oil discharge monitoring and control system shall be of a design approved by the Administration. In considering the design of the oil content meter to be incorporated into the system, the Administration shall have regard to the specification recommended by the Organization.[[3]](#footnote-3)* The system shall be fitted with a recording device to provide a continuous record of the oil content in parts per million. This record shall be identifiable as to time and date and shall be kept for at least three years. The monitoring and control system shall come into operation when there is any discharge of effluent into the sea and shall be such as will ensure that any discharge of oily mixture is automatically stopped when the oil content of effluent exceeds that permitted by Regulation 9(1)(b) of this Annex. Any failure of this monitoring and control system shall stop the discharge and be noted in the Oil Record Book. The defective unit shall be made operable before the ship commences its next voyage unless it is proceeding to a repair port. Existing ships shall comply with all of the provisions specified above except that the stopping of the discharge may be performed manually.\n\n(6) Oily‑water separating equipment or an oil filtering system shall be of a design approved by the Administration and shall be such as will ensure that any oily mixture discharged into the sea after passing through the separator or filtering systems shall have an oil content of not less than 100 parts per million. In considering the design of such equipment, the Administration shall have regard to the specification recommended by the Organization.[[4]](#footnote-4)*\n\n(7) The oil filtering system referred to in paragraph (2)(b) of this Regulation shall be of a design approved by the Administration and shall be such that it will accept the discharge from the separating system and produce an effluent the oil content of which does not exceed 15 parts per million. It shall be provided with alarm arrangements to indicate when this level cannot be maintained.\n\nRegulation 17\n\n*Tanks for Oil Residues (Sludge)*\n\n(1) Every ship of 400 tons gross tonnage and above shall be provided with a tank or tanks of adequate capacity, having regard to the type of machinery and length of voyage, to receive the oily residues (sludges) which cannot be dealt with otherwise in accordance with the requirements of this Annex, such as those resulting from the purification of fuel and lubricating oils and oil leakages in the machinery spaces.\n\n(2) In new ships, such tanks shall be designed and constructed so as to facilitate their cleaning and the discharge of residues to reception facilities. Existing ships shall comply with this requirement as far as is reasonable and practicable.\n\nRegulation 18\n\n(1) In every oil tanker, a discharge manifold for connexion to reception facilities for the discharge of dirty ballast water or oil contaminated water shall be located on the open deck on both sides of the ship.\n\n(2) In every oil tanker, pipelines for the discharge to the sea of effluent which may be permitted under Regulation 9 of this Annex shall be led to the open deck or to the ship’s side above the waterline in the deepest ballast condition. Different piping arrangements to permit operation in the manner permitted in sub‑paragraphs (4)(a) and (b) of this Regulation may be accepted.\n\n(3) In new oil tankers means shall be provided for stopping the discharge of effluent into the sea from a position on upper deck or above located so that the manifold in use referred to in paragraph (1) of this Regulation and the effluent from the pipelines referred to in paragraph (2) of this Regulation may be visually observed. Means for stopping the discharge need not be provided at the observation position if a positive communication system such as telephone or radio system is provided between the observation position and the discharge control position.\n\n(4) All discharges shall take place above the waterline except as follows:\n\n(a) Segregated ballast and clean ballast may be discharged below the waterline in ports or at off‑shore terminals.\n\n(b) Existing ships which, without modification, are not capable of discharging segregated ballast above the waterline may discharge segregated ballast below the waterline provided that an examination of the tank immediately before the discharge has established that no contamination with oil has taken place.\n\nRegulation 19\n\n*Standard Discharge Connection*\n\nTo enable pipes of reception facilities to be connected with the ship’s discharge pipeline for residues from machinery bilges, both lines shall be fitted with a standard discharge connection in accordance with the following table:\n\n**STANDARD DIMENSIONS OF FLANGES FOR DISCHARGE CONNECTIONS**\n\n- Description Dimension\n- Outside diameter 215 mm\n- Inner diameter According to pipe outside diameter\n- Bolt circle diameter 183 mm\n- Slots in flange 6 holes 22 mm in diameter equidistantly placed on a bolt circle of the above diameter, slotted to the flange periphery.

Each section of the book shall be signed by the officer or officers in charge of the operations concerned and shall be countersigned by the Master of the ship. The entries in the Oil Record Book shall be in an official language of the State whose flag the ship is entitled to fly, and, for ships holding an International Oil Pollution Prevention Certificate (1973), in English or French. The entries in an official national language of the State whose flag the ship is entitled to fly shall prevail in case of a dispute or discrepancy.\n\n(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 the ship. It shall be preserved for a period of three years after the last entry has been made.\n\n(6) The competent authority of the Government of a Party to the Convention may inspect the Oil Record Book on board any ship to which this Annex applies while the ship is in its port or off‑shore terminals 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 entry. Any copy so made which has been certified by the Master of the ship as a true copy of an entry in the ship’s Oil Record Book shall be made 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 competent authority under this paragraph shall be performed as expeditiously as possible without causing the ship to be unduly delayed.\n\nRegulation 21\n\n*Special Requirements for Drilling Rigs and other Platforms*\n\nFixed and floating drilling rigs when engaged in the exploration, exploitation and associated off‑shore processing of sea‑bed mineral resources and other platforms shall comply with the requirements of this Annex applicable to ships of 400 tons gross tonnage and above other than oil tankers, except that:\n\n(a) they shall be equipped as far as practicable with the installations required in Regulations 16 and 17 of this Annex;\n\n(b) they shall keep a record of all operations involving oil or oily mixture discharges, in a form approved by the Administration; and\n\n(c) in any special area and subject to the provisions of Regulation 11 of this Annex, the discharge into the sea of oil or oily mixture shall be prohibited except when the oil content of the discharge without dilution does not exceed 15 parts per million.\n\nCHAPTER III — REQUIREMENTS FOR MINIMIZING OIL POLLUTION FROM OIL TANKERS DUE TO SIDE AND BOTTOM DAMAGES\n\nRegulation 22\n\n*Damage Assumptions*\n\n(1) For the purpose of calculating hypothetical oil outflow from oil tankers, three dimensions of the extent of damage of a parallelepiped on the side and bottom of the ship are assumed as follows. In the case of bottom damages two conditions are set forth to be applied individually to the stated portions of the oil tanker.\n\n(a) *Side damage*\n\n- (i) Longitudinal extent (*l*c): or 14.5 metres,\nwhichever is less\n- (ii) Transverse extent (tc):\n(inboard from the ship’s side at right angles to the centreline at the level corresponding to the assigned summer freeboard) B or 11.5 metres,\nwhichever is less\n- (iii) Vertical extent (vc): from the base line upwards without limit\n\n(b) *Bottom damage*\n\n|  | For 0.3L from the forward perpendicular of the ship | Any other part of the ship |\n| --- | --- | --- |\n| (i) Longitudinal extent (*l*s): | L    10 | L or 5 metres,   10    whichever is less |\n| (ii) Transverse extent (ts): | B or 10 metres,   6    whichever is less but not   less than 5 metres | 5 metres |\n| (iii) Vertical extent from the base line (vs): | B or 6 metres,    15    whichever is less |  |\n\n(2) Wherever the symbols given in this Regulation appear in this Chapter, they have the meaning as defined in this Regulation.\n\nRegulation 23\n\n*Hypothetical Outflow of Oil*\n\n(1) The hypothetical outflow of oil in the case of side damage (Oc) and bottom damage (Os) shall be calculated by the following formulae with respect to compartments breached by damage to all conceivable locations along the length of the ship to the extent as defined in Regulation 22 of this Annex.\n\n(a) for side damages:\n\n\t![]() (I)\n\n(b) for bottom damages:\n\n\t![]() (II)\n\nwhere: Wi = volume of a wing tank in cubic metres assumed to be breached by the damage as specified in Regulation 22 of this Annex; Wi for a segregated ballast tank may be taken equal to zero,\n\nCi = volume of a centre tank in cubic metres assumed to be breached by the damage as specified in Regulation 22 of this Annex; Ci for a segregated ballast tank may be taken equal to zero,\n\n| ![]() | when bi is equal to or greater than tc, Ki shall be taken equal to zero, |\n| ![]() | when hi is equal to or greater than vs, Zi shall be taken equal to zero, |\n\nbi = width of wing tank in metres under consideration measured inboard from the ship’s side at right angles to the centreline at the level corresponding to the assigned summer freeboard,\n\nhi = minimum depth of the double bottom in metres under consideration; where no double bottom is fitted hi shall be taken equal to zero.\n\nWhenever symbols given in this paragraph appear in this Chapter, they have the meaning as defined in this Regulation.\n\n(2) If a void space or segregated ballast tank of a length less than lc as defined in Regulation 22 of this Annex is located between wing oil tanks, Oc in formula (I) may be calculated on the basis of volume Wi being the actual volume of one such tank (where they are of equal capacity) or the smaller of the two tanks (if they differ in capacity), adjacent to such space, multiplied by Si as defined below and taking for all other wing tanks involved in such a collision the value of the actual full volume.\n\nwhere *l*i = length in metres of void space or segregated ballast tank under consideration.\n\n(3) (a) Credit shall only be given in respect of double bottom tanks which are either empty or carrying clean water when cargo is carried in the tanks above.\n\n(b) Where the double bottom does not extend for the full length and width of the tank involved, the double bottom is considered non‑existent and the volume of the tanks above the area of the bottom damage shall be included in formula (II) even if the tank is not considered breached because of the installation of such a partial double bottom.\n\n(c) Suction wells may be neglected in the determination of the value hi provided such wells are not excessive in area and extend below the tank for a minimum distance and in no case more than half the height of the double bottom. If the depth of such a well exceeds half the height of the double bottom, hi shall be taken equal to the double bottom height minus the well height.\n\nPiping serving such wells if installed within the double bottom shall be fitted with valves or other closing arrangements located at the point of connexion to the tank served to prevent oil outflow in the event of damage to the piping. Such piping shall be installed as high from the bottom shell as possible. These valves shall be kept closed at sea at any time when the tank contains oil cargo, except that they may be opened only for cargo transfer needed for the purpose of trimming of the ship.\n\n(4) In the case where bottom damage simultaneously involves four centre tanks, the value of Os may be calculated according to the formula\n\n\t![]() (III)\n\n(5) An Administration may credit as reducing oil outflow in case of bottom damage, an installed cargo transfer system having an emergency high suction in each cargo oil tank, capable of transferring from a breached tank or tanks to segregated ballast tanks or to available cargo tankage if it can be assured that such tanks will have sufficient ullage. Credit for such a system would be governed by ability to transfer in two hours of operation oil equal to one half of the largest of the breached tanks involved and by availability of equivalent receiving capacity in ballast or cargo tanks. The credit shall be confined to permitting calculation of Os according to formula (III). The pipes for such suctions shall be installed at least at a height not less than the vertical extent of the bottom damage vs. The Administration shall supply the Organization with the information concerning the arrangements accepted by it, for circulation to other Parties to the Convention.\n\nRegulation 24\n\n*Limitation of Size and Arrangement of Cargo Tanks*\n\n(1) Every new oil tanker shall comply with the provisions of this Regulation. Every existing oil tanker shall be required, within two years after the date of entry into force of the present Convention, to comply with the provisions of this Regulation if such a tanker falls into either of the following categories:\n\n(a) a tanker, the delivery of which is after 1 January 1977; or\n\n(b) a tanker to which both the following conditions apply:\n\n(i) delivery is not later than 1 January 1977; and\n\n(ii) the building contract is placed after 1 January 1974, or in cases where no building contract has previously been placed, the keel is laid or the tanker is at a similar stage of construction after 30 June 1974.\n\n(2) Cargo tanks of oil tankers shall be of such size and arrangements that the hypothetical outflow Oc or Os calculated in accordance with the provisions of Regulation 23 of this Annex anywhere in the length of the ship does not exceed 30,000 cubic metres or 4003 DW, whichever is the greater, but subject to a maximum of 40,000 cubic metres.\n\n(3) The volume of any one wing cargo oil tank of an oil tanker shall not exceed seventy‑five per cent of the limits of the hypothetical oil outflow referred to in paragraph (2) of this Regulation. The volume of any one centre cargo oil tank shall not exceed 50,000 cubic metres. However, in segregated ballast oil tankers as defined in Regulation 13 of this Annex, 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 tc.\n\n(4) The length of each cargo tank shall not exceed 10 metres or one of the following values, whichever is the greater:\n\n(a) where no longitudinal bulkhead is provided:\n\n0.1L\n\n(b) where a longitudinal bulkhead is provided at the centreline only:\n\n0.15L\n\n(c) where two or more longitudinal bulkheads are provided:\n\n(i) for wing tanks:\n\n0.2L\n\n(ii) for centre tanks:\n\n(1) if ![]() is equal to or greater than ![]():\n\n0.2L\n\n(2) if ![]() is less than ![]():\n\n— where no centreline longitudinal bulkhead is provided:\n\n(0.5 ![]() + 0.1) L\n\n— where a centreline longitudinal bulkhead is provided:\n\n(0.25 ![]() + 0.15) L\n\n(5) In order not to exceed the volume limits established by paragraphs (2), (3) and (4) of this Regulation and irrespective of the accepted type of cargo transfer system installed, when such system interconnects 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.\n\n(6) Lines of piping which run through cargo tanks in a position less than tc from the ship’s side or less than vc from the ship’s bottom 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 only for cargo transfer needed for the purpose of trimming of the ship.\n\nRegulation 25\n\n*Subdivision and Stability*\n\n(1) Every new oil tanker shall comply with the subdivision and damage stability criteria as specified in paragraph (3) of this Regulation, after the assumed side or bottom damage as specified in paragraph (2) of this Regulation, for any operating draught reflecting actual partial or full load conditions consistent with trim and strength of the ship as well as specific gravities of the cargo. Such damage shall be applied to all conceivable locations along the length of the ship as follows:\n\n(a) in tankers of more than 225 metres in length, anywhere in the ship’s length;\n\n(b) in tankers of more than 150 metres, but not exceeding 225 metres in length, anywhere in the ship’s length except involving either after or forward bulkhead bounding the machinery space located aft. The machinery space shall be treated as a single floodable compartment;\n\n(c) in tankers not exceeding 150 metres in length, anywhere in the ship’s length between adjacent transverse bulkheads with the exception of the machinery space. For tankers of 100 metres or less in length where all requirements of paragraph (3) of this Regulation cannot be fulfilled without materially impairing the operational qualities of the ship, Administrations may allow relaxations from these requirements.\n\nBallast conditions where the tanker is not carrying oil in cargo tanks excluding any oil residues, shall not be considered.\n\n(2) The following provisions regarding the extent and the character of the assumed damage shall apply:\n\n(a) The extent of side or bottom damage shall be as specified in Regulation 22 of this Annex, except that the longitudinal extent of bottom damage within 0.3L from the forward perpendicular shall be the same as for side damage, as specified in Regulation 22(1)(a)(i) of this Annex. If any damage of lesser extent results in a more severe condition such damage shall be assumed.\n\n(b) Where the damage involving transverse bulkheads is envisaged as specified in sub‑paragraphs (1)(a) and (b) of this Regulation, transverse watertight bulkheads shall be spaced at least at a distance equal to the longitudinal extent of assumed damage specified in sub‑paragraph (a) of this paragraph in order to be considered effective. Where transverse bulkheads are spaced at a lesser distance, one or more of these bulkheads within such extent of damage shall be assumed as non‑existent for the purpose of determining flooded compartments.\n\n(c) Where the damage between adjacent transverse watertight bulkheads is envisaged as specified in sub‑paragraph (1)(c) of this Regulation, no main transverse bulkhead or a transverse bulkhead bounding side tanks or double bottom tanks shall be assumed damaged, unless:\n\n(i) the spacing of the adjacent bulkheads is less than the longitudinal extent of assumed damage specified in sub‑paragraph (a) of this paragraph; or\n\n(ii) there is a step or a recess in a transverse bulkhead of more than 3.05 metres in length, located within the extent of penetration of assumed damage. The step formed by the after peak bulkhead and after peak tank top shall not be regarded as a step for the purpose of this Regulation.\n\n(d) If pipes, ducts or tunnels are situated within the assumed extent of damage, arrangements shall be made so that progressive flooding cannot thereby extend to compartments other than those assumed to be floodable for each case of damage.\n\n(3) Oil tankers shall be regarded as complying with the damage stability criteria if the following requirements are met:\n\n(a) The final waterline, taking into account sinkage, heel and trim, shall be below the lower edge of any opening through which progressive flooding may take place. Such openings shall include air pipes and those which are closed by means of weathertight doors or hatch covers and may exclude those openings closed by means of watertight manhole covers and flush scuttles, small watertight cargo tank hatch covers which maintain the high integrity of the deck, remotely operated watertight sliding doors, and side scuttles of the non‑opening type.\n\n(b) In the final stage of flooding, the angle of heel due to unsymmetrical flooding shall not exceed 25 degrees, provided that this angle may be increased up to 30 degrees if no deck edge immersion occurs.\n\n(c) The stability in the final stage of flooding shall be investigated and may be regarded as sufficient if the righting lever curve has at least a range of 20 degrees beyond the position of equilibrium in association with a maximum residual righting lever of at least 0.1 metre. The Administration shall give consideration to the potential hazard presented by protected or unprotected openings which may become temporarily immersed within the range of residual stability.\n\n(d) The Administration shall be satisfied that the stability is sufficient during intermediate stages of flooding.\n\n(4) The requirements of paragraph (1) of this Regulation shall be confirmed by calculations which take into consideration the design characteristics of the ship, the arrangements, configuration and contents of the damaged compartments; and the distribution, specific gravities and the free surface effect of liquids. The calculations shall be based on the following:\n\n(a) Account shall be taken of any empty or partially filled tank, the specific gravity of cargoes carried, as well as any outflow of liquids from damaged compartments.\n\n(b) The permeabilities are assumed as follows:\n\n| *Spaces* | *Permeability* |\n| Appropriated to stores | 0.60 |\n| Occupied by accommodation | 0.95 |\n| Occupied by machinery | 0.85 |\n| Voids | 0.95 |\n| Intended for consumable liquids | 0 or 0.95* |\n| Intended for other liquids | 0 to 0.95† |\n\n* Whichever results in the more severe requirements.\n\n† The permeability of partially filled compartments shall be consistent with the amount of liquid carried.\n\n(c) The buoyancy of any superstructure directly above the side damage shall be disregarded. The unflooded parts of superstructures beyond the extent of damage, however, may be taken into consideration provided that they are separated from the damaged space by watertight bulkheads and the requirements of sub‑paragraph (3)(a) of this Regulation in respect of these intact spaces are complied with. Hinged watertight doors may be acceptable in watertight bulkheads in the superstructure.\n\n(d) The free surface effect shall be calculated at an angle of heel of 5 degrees for each individual compartment. The Administration may require or allow the free surface corrections to be calculated at an angle of heel greater than 5 degrees for partially filled tanks.\n\n(e) In calculating the effect of free surfaces of consumable liquids it shall be assumed that, for each type of liquid at least one transverse pair or a single centreline tank has a free surface and the tank or combination of tanks to be taken into account shall be those where the erect of free surfaces is the greatest.\n\n(5) The Master of every oil tanker and the person in charge of a non‑self‑propelled oil tanker to which this Annex applies shall be supplied in an approved form with:\n\n(a) information relative to loading and distribution of cargo necessary to ensure compliance with the provisions of this Regulation; and\n\n(b) data on the ability of the ship to comply with damage stability criteria as determined by this Regulation, including the effect of relaxations that may have been allowed under sub‑paragraph (1)(c) of this Regulation.\n\n**Appendix I**\n\nLIST OF OILS[[5]](#footnote-5)*\n\n| **Asphalt solutions** | **Gasoline Blending Stocks** |\n| Blending Stocks | Alkylates‑fuel |\n| Roofers Flux | Reformates |\n| Straight Run Residue | Polymer‑fuel |\n| **Oils** | **Gasolines** |\n| Clarified | Casinghead (natural) |\n| Crude Oil | Automotive |\n| Mixtures containing crude oil | Aviation |\n| Diesel Oil | Straight Run |\n| Fuel Oil No. 4 | Fuel Oil No. 1 (Kerosene) |\n| Fuel Oil No. 5 | Fuel Oil No. 1‑D |\n| Fuel Oil No. 6 | Fuel Oil No. 2 |\n| Residual Fuel Oil | Fuel Oil No. 2‑D |\n| Road Oil |  |\n| Transformer Oil | **Jet Fuels** |\n| Aromatic Oil (excluding vegetable oil) | JP‑1 (Kerosene) |\n| Lubricating Oils and Blending Stocks | JP‑3 |\n| Mineral Oil | JP‑4 |\n| Motor Oil | JP‑5 (Kerosene, Heavy) |\n| Penetrating Oil | Turbo Fuel |\n| Spindle Oil | Kerosene |\n| Turbine Oil | Mineral Spirit |\n| **Distillates** | **Naphtha** |\n| Straight Run | Solvent |\n| Flashed Feed Stocks | Petroleum |\n|  | Heartcut Distillate Oil |\n| **Gas Oil** |  |\n| Cracked |  |\n\nFORM OF CERTIFICATE\n\nINTERNATIONAL OIL POLLUTION PREVENTION CERTIFICATE (1973)\n\nIssued under the Provisions of the International Convention for the Prevention of Pollution from Ships, 1973, under the Authority of the Government of\n\n................................................................................................................................(*full designation of the country*)\n\nby ...........................................................................................................................\n\n(*full designation of the competent person or organisation authorized under the provision of the International Convention for the Prevention of Pollution from Ships, 1973*)\n\n| Name of Ship | Distinctive   Number or   Letter | Port of   Registry | Gross   Tonnage |\n\nType of Ship:\n\nOil tanker, including combination carrier[[6]](#footnote-6)*\n\nAsphalt carrier*\n\nShip other than an oil tanker with cargo tanks coming under Regulation 2(2) of Annex I of the Convention*\n\nNew/existing ship*\n\nDate of building or major conversion contract ......................................................\n\nDate on which keel was laid or ship was at a similar stage of  \nconstruction or on which major conversion was commenced ...............................\n\nDate of delivery or completion of major conversion .............................................\n\nPART A ALL SHIPS\n\nThe ship is equipped with:\n\nfor ships of 400 tons gross tonnage and above:\n\n(a) oily‑water separating equipment[[7]](#footnote-7)* (capable of producing the effluent with oil content not exceeding 100 parts per million) or\n\n(b) an oil filtering system* (capable of producing the effluent with oil content not exceeding 100 parts per million)\n\nfor ships of 10,000 tons gross tonnage and above:\n\n(c) an oil discharge monitoring and control system* (additional to (a) or (b) above) or\n\n(d) oily‑water separating equipment and an oil filtering system* (capable of producing the effluent with oil content not exceeding 15 parts per million) in lieu of (a) or (b) above.\n\nParticulars of requirements from which exemption is granted under Regulation 2(2) and 2(4)(a) of Annex I of the Convention:\n\n................................................................................................................................\n\n................................................................................................................................\n\n*Remarks*:\n\nPART B OIL TANKER[[8]](#footnote-8)1, [[9]](#footnote-9)2\n\nDeadweight .....................metric tons.

II**\n\n**REGULATIONS FOR THE CONTROL OF POLLUTION BY NOXIOUS LIQUID SUBSTANCES IN BULK**\n\nFor the purposes of this Annex:\n\n(1) “Chemical tanker” means a ship constructed or adapted primarily to carry a cargo of noxious liquid substances in bulk and includes an “oil tanker” as defined in Annex I of the Present Convention when carrying a cargo or part cargo of noxious liquid substances in bulk.\n\n(2) “Clean ballast” means ballast carried in a tank which, since it was last used to carry a cargo containing a substance in Category A, B, C or D has been thoroughly cleaned and the residues resulting therefrom have been discharged and the tank emptied in accordance with the appropriate requirements of this Annex.\n\n(3) “Segregated ballast” means ballast water introduced into a tank permanently allocated to the carriage of ballast or to the carriage of ballast or cargoes other than oil or noxious liquid substances as variously defined in the Annexes of the present Convention, and which is completely separated from the cargo and oil fuel system.\n\n(4) “Nearest land” is as defined in Regulation 1(9) of Annex I of the present Convention.\n\n(5) “Liquid substances” are those having a vapour pressure not exceeding 2.8 kp/cm2 at a temperature of 37.8°C.\n\n(6) “Noxious liquid substance” means any substance designated in Appendix II to this Annex or provisionally assessed under the provisions of Regulation 3(4) as falling into Category A, B, C or D.\n\n(7) “Special area” means a sea area where for recognized technical reasons in relation to its oceanographic and ecological condition and to its peculiar transportation traffic the adoption of special mandatory methods for the prevention of sea pollution by noxious liquid substances is required.\n\nSpecial areas shall be:\n\n(a) The Baltic Sea Area, and\n\n(b) The Black Sea Area.\n\n(8) “Baltic Sea Area” is as defined in Regulation 10(1)(b) of Annex I of the present Convention.\n\n(9) “Black Sea Area” is as defined in Regulation 10(1)(c) of Annex I of the present Convention.\n\n(1) Unless expressly provided otherwise the provisions of this Annex shall apply to all ships carrying noxious liquid substances in bulk.\n\n(2) Where a cargo subject to the provisions of Annex I of the present Convention is carried in a cargo space of a chemical tanker, the appropriate requirements of Annex I of the present Convention shall also apply.\n\n(3) Regulation 13 of this Annex shall apply only to ships carrying substances which are categorized for discharge control purposes in Category A, B or C.\n\n*Categorization and Listing of Noxious Liquid Substances*\n\n(1) For the purpose of the Regulations of this Annex, except Regulation 13, noxious liquid substances shall be divided into four categories as follows:\n\n(a) Category A — Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a major hazard to either marine resources or human health or cause serious harm to amenities or other legitimate uses of the sea and therefore justify the application of stringent anti‑pollution measures.\n\n(b) Category B — Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a hazard to either marine resources or human health or cause harm to amenities or other legitimate uses of the sea and therefore justify the application of special anti‑pollution measures.\n\n(c) Category C — Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a minor hazard to either marine resources or human health or cause minor harm to amenities or other legitimate uses of the sea and therefore require special operational conditions.\n\n(d) Category D — Noxious liquid substances which if discharged into the sea from tank cleaning or deballasting operations would present a recognizable hazard to either marine resources or human health or cause minimal harm to amenities or other legitimate uses of the sea and therefore require some attention in operational conditions.\n\n(2) Guidelines for use in the categorization of noxious liquid substances are given in Appendix I to this Annex.\n\n(3) The list of noxious liquid substances carried in bulk and presently categorized which are subject to the provisions of this Annex is set out in Appendix II to this Annex.\n\n(4) Where it is proposed to carry a liquid substance in bulk which has not been categorized under paragraph (1) of this Regulation or evaluated as referred to in Regulation 4(1) of this Annex, the Governments of Parties to the Convention involved in the proposed operation shall establish and agree on a provisional assessment for the proposed operation on the basis of the guidelines referred to in paragraph (2) of this Regulation. Until full agreement between the Governments involved has been reached, the substance shall be carried under the most severe conditions proposed. As soon as possible, but not later than ninety days after its first carriage, the Administration concerned shall notify the organization and provide details of the substance and the provisional assessment for prompt circulation to all Parties for their information and consideration.

The Act explicitly permits declaring substances/categories by regulation (ss.18–19).  \n\nWhy this matters (stated purpose and practical implications)\n\n- The Act gives statutory force to detailed international rules intended to prevent and control marine pollution from ships: reporting, certification, equipment standards (oil‑water separators, monitoring systems), tank cleaning and limits on where and how residues can be discharged (see Annex material reproduced in Schedules; ss.13,15,16,20,26).  \n- If you operate ships, cargo tanks, transfer apparatus, or run ports/terminals, the Act sets operational requirements (equipment, monitoring, record‑keeping), mandatory surveys and certificates, potential criminal and civil liability and the prospect of being billed for clean‑up costs (see ss.13–16, 20–25, 27, 33).  \n\nTesting the stated purpose against costs, incentives and trade‑offs\n\n- Intended effect claimed: to prevent and deter marine pollution by imposing strict operational standards and sanctions. This is implemented by: technical requirements (equipment and monitoring systems) and operational controls (where/when discharges are permitted) — see ss.8(6), 15–16, 20(4)–(11).  \n- Direct costs and compliance burden (who pays): shipowners, masters and terminal operators bear equipment and survey costs (oil discharge monitoring systems, separators, slop tanks, certificates — ss.15–16, Regs in Schedules). Ports and States must provide reception facilities and may have to run inspection/survey regimes (see Regulation/Annex material in Schedules and s.35 on fees and orders).  \n- Incentives and behavioural effects: the law raises the marginal cost of discharging at sea and creates incentives to: (a) invest in on‑board treatment and monitoring; (b) use reception facilities ashore; (c) alter routing or timing to meet distance/depth/speed conditions for permitted discharges (see s.8(6), s.20(4)–(11)); (d) change tank cleaning and cargo handling practices. Those adjustments change operating costs and logistic choices for carriers and charterers.  \n- Concentrated benefits / diffuse costs: operators of reception facilities and surveyors (including recognized organizations) gain business from compliance; shipping operators and small vessel owners face concentrated compliance costs (s.35, Schedules re: survey/certificates).  \n- Enforcement trade‑offs and capture risk: the Act delegates significant technical discretion to regulators (prescribed officers, inspectors, Minister, and regulations that adopt outside standards — ss.6, 29, 35, 37). That delegation is necessary for technical implementation but concentrates decision‑making in agencies and raises implementation/consistency risk.  \n- Opportunity cost and substitution effects: where at‑sea discharge is constrained, operators may substitute ashore disposal, increased retention on board, altered ship designs, or changes in cargo mix and contracts. These entail extra cost and can change freight prices.  \n\nImplementation risk and compliance friction\n\n- Complexity and technical detail depend on international standards (Schedules 1–5). That reduces legal ambiguity but creates dependency on evolving international rules and on the State’s ability to provide reception infrastructure and timely inspections.  \n- Practical frictions: record‑keeping, multi‑year retention obligations (Oil Record Books: ss.13–15; Cargo Record Books: ss.23–25), and frequent survey/certification create administrative load for shipowners and port operators.  \n- Prosecutorial and civil enforcement features: there is no time limit for prosecutions (s.30(1)), and authorities can recover cleanup costs as a debt whether or not a conviction occurs (s.27(3)). This increases enforcement leverage but also legal risk for defendants.  \n\nNet effect on private enterprise and markets (brief)\n\n- Compliance raises operating costs (capital and running), which are likely to be passed through in freight and service charges.  \n- Larger operators and ships are better placed to amortise equipment/survey costs; smaller operators bear proportionally higher burdens, potentially reducing competition in some trades.  \n- Ports providing reception facilities can capture service revenue; where reception infrastructure is inadequate, the Act authorises States to require improvement (see s.35 and Annex/Regulation obligations in Schedules).\n\nKey sections to read for operators and port authorities: ss.3 (definitions and incorporation), 8 & 20 (offences for oil and noxious substances), 11–12 & 22 (reporting duties), 13 & 23 (record books), 15–16 (on‑board equipment and monitoring), 27–29 (powers, cost recovery and inspectors), 35 (regulations, exemptions and fees) and Schedules 1–5 (the reproduced MARPOL/Protocol technical rules)."},"summary":{"complexity_score":1,"scope_assessment":{"changed":false,"description":"Scope cannot be assessed as the legislative text was not available for analysis.
