International Convention for the Prevention of Pollution from Ships, 1973

The Parties to the Convention,

Being conscious of the need to preserve the human environment in general and the marine environment in particular,

Recognizing that deliberate, negligent or accidental release of oil and other harmful substances from ships constitutes a serious source of pollution,

Recognizing also the importance of the International Convention for the Prevention of Pollution of the Sea by Oil, 1954, as being the first multilateral instrument to be concluded with the prime objective of protecting the environment, and appreciating the significant contribution which that Convention has made in preserving the seas and coastal environment from pollution,

Desiring to achieve the complete elimination of intentional pollution of the marine environment by oil and other harmful substances and the minimization of accidental discharge of such substances,

Considering that this object may best be achieved by establishing rules not limited to oil pollution having a universal purport,

Have agreed as follows:

Article 1 General Obligations under the Convention

(1). The Parties to the Convention undertake to give effect to the provisions of the present Convention and those Annexes thereto by which they are bound, in order to prevent the pollution of the marine environment by the discharge of harmful substances or effluents containing such substances in contravention of the present Convention.
(2). Unless expressly provided otherwise, a reference to the present Convention constitutes at the same time a reference to its Protocols and to the Annexes.

Article 2 Definitions

For the purposes of the present Convention, unless expressly provided otherwise:

(1)“Regulations” means the Regulations contained in the Annexes to the present Convention.
(2)“Harmful substance” means any substance which, if introduced into the sea, is liable to create hazards to human health, to harm living resources and marine life, to damage amenities or to interfere with other legitimate uses of the sea, and includes any substance subject to control by the present Convention.
(3)
- (a)“Discharge”, in relation to harmful substances or effluents containing such substances, means any release howsoever caused from a ship and includes any escape, disposal, spilling, leaking, pumping, emitting or emptying;
- (b)“Discharge” does not include:
  - (i)dumping within the meaning of the Convention on the Prevention of Marine Pollution by Dumping, of Wastes and Other Matter, done at London on 13 November 1972; or
  - (ii)release of harmful substances directly arising from the exploration, exploitation and associated off-shore processing of seabed mineral resources; or
  - (iii)release of harmful substances for purposes of legitimate scientific research into pollution abatement or control.
(4)“Ship” means a vessel of any type whatsoever operating in the marine environment and includes hydrofoil boats, air-cushion vehicles, submersibles, floating craft and fixed or floating platforms.
(5)“Administration” means the Government of the State under whose authority the ship is operating. 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.
(6)“Incident” means an event involving the actual or probable discharge into the sea of a harmful substance, or effluents containing such a substance.
(7)“Organization” means the Inter-Governmental Maritime Consultative Organization.

Article 3 Application

(1). The present Convention shall apply to:
- (a)ships entitled to fly the flag of a Party to the Convention; and
- (b)ships not entitled to fly the flag of a Party but which operate under the authority of a Party.
(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.
(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.

Article 4 Violation

(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.
(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:
- (a)cause proceedings to be taken in accordance with its law; or
- (b)furnish to the Administration of the ship such information and evidence as may be in its possession that a violation has occurred.
(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.
(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.

Article 5 Certificates and Special Rules on Inspection of Ships

(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.
(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.
(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.
(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.

Article 6 Detection of Violations and Enforcement of the Convention

(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.
(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.
(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.
(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.
(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.

Article 7 Undue Delay to Ships

(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.
(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.

- (b)notify the Organization with complete details of such arrangements for circulation to other Parties and Member States of the Organization.
(3). Whenever a Party receives a report under the provisions of the present Article, that Party shall relay the report without delay to:
- (a)the Administration of the ship involved; and
- (b)any other State which may be affected.
(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.

(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.
(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.

CHAPTER III REQUIREMENTS FOR MINIMIZING OIL POLLUTION FROM OIL TANKERS DUE TO SIDE AND BOTTOM DAMAGES

Regulation 22 Damage Assumptions

(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.
(2)Wherever the symbols given in this Regulation appear in this Chapter, they have the meaning as defined in this Regulation.

Regulation 23 Hypothetical Outflow of Oil

(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.

where:
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,
Ci= 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,

bi = width of wing tank in metres under consideration measured inboard from the ship's side alright angles to the centreline at the level corresponding to the assigned summer freeboard,
hj = minimum depth of the double bottom in metres under consideration; where no double bottom is fitted hi shall be taken equal to zero.
Whenever symbols given in this paragraph appear in this Chapter, they have the meaning as defined in this Regulation.
(2)If a void space or segregated ballast tank of a length less than λe 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.

where λj = length in metres of void space or segregated ballast tank under consideration.
(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.
- (b)Where the double bottom does not extend for the full length and width of the tank involved, the double bottom is considered nonexistent 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.
- (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.
  Piping 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.
(4)In the case where bottom damage simultaneously involves four centre tanks, the value of Os may be calculated according to the formula:
(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.

Regulation 24 Limitation of Size and Arrangement of Cargo Tanks

(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:
- (a)a tanker, the delivery of which is after 1 January 1977; or
- (b)a tanker to which both the following conditions apply:
  - (i)delivery is not later than 1 January 1977; and
  - (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.
(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
(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 λc in length, may be increased to the maximum limit of hypothetical oil outflow provided that the width of the wing tanks exceeds tc.
(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:
  (0.5 bi/B + 0.1) L
  but not to exceed 0.2 L
- b)Where a centreline longitudinal bulkhead is provided inside the cargo tanks:
  (0.25 bi/B + 0.15) L
- c)Where two or more longitudinal bulkheads are provided inside the cargo tanks:
  - (i)for wing cargo tanks:
    0.2 L
  - (ii)for centre cargo tanks:
    
    (1)if bi/B is egual to or greater than one fifth:
    0.2 L
    
    (2)if bi/B is less than one fifth:
    
    Where no centreline longitudinal bulkhead is provided:
    (0.5 bi/B + 0.1) L
    
    Where a centreline longitudinal bulkhead is provided:
    (0.25 bi/B + 0.15) L
- d)“bi” is the minimum distance from the ship's side to the outer longitudinal bulkhead of the tank in question measured inboard at right angels 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) of this Regulation and irrespective of the accepted type of cargo transfer system installed, when such 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 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.

Regulation 25 Subdivision and Stability

(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:
- (a)in tankers of more than 225 metres in length, any where in the ship's length;
- (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;
- (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.
Ballast conditions where the tanker is not carrying oil in cargo tanks excluding any oil residues, shall not be considered.
(2)The following provisions regarding the extent and the character of the assumed damage shall apply:
- (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.
- (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 subparagraph (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.
- (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:
  - (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
  - (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.
- (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.
(3)Oil tankers shall be regarded as complying with the damage stability criteria if the following requirements are met
- (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.
- (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.
- (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.
- (d)The Administration shall be satisfied that the stability is sufficient during intermediate stages of flooding.

(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:

(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.

(b)The permeabilities are assumed as follows:

Spaces	Permeability
Appropriated to stores Occupied by accommodation Occupied by machinery Voids	0.60 0.95 0.85 0.95
Intended for consumable liquids	0 or 0.95*)
Intended for other liquids	0 to 0.95 **)

*) Whichever results in the more severe requirements.
**) The permeability of partially filled compartments shall be consistent with the amount of liquid carried.

(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.
(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.
(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 effect of free surfaces is the greatest.

(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:
- (a)information relative to loading and distribution of cargo necessary to ensure compliance with the provisions of this Regulation; and
- (b)date 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.

Regulation 3 Categorization and Listing of Noxious Liquid Substances

(1)For the purpose of the Regulations of this Annex noxious liquid substances shall be divided into four categories as follows:
- (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.
- (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.
- (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.
- (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.
(2)Guidelines for use in the categorization of noxious liquid substances are given in Appendix I to this Annex.
(3)Noxious liquid substances carried in bulk which are presently categorized as category A, B, C or D and subject to the provisions of this Annex are referred to in appendix II to this Annex.
(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 Government of each Party shall have a period of ninety days in which to forward its comments to the Organization, with a view to the assessment of the substance.

Regulation 4 Other Liquid Substances

(1)The substances referred to in appendix III to this Annex have been evaluated and found to fall outside category A, B, C and D, as defined in regulation 3(1) of this Annex because they are at present considered to present no harm to human health, marine resources, amenities or other legitimate uses of the sea, when discharged into the sea from tank cleaning or deballasting operation.
(2)The discharge of bilge or ballast water or other residues or mixtures containing only substances referred to in appendix III to this Annex shall not be subject to any requirement of this Annex.
(3)The discharge into the sea of clean ballast or segregated ballast shall not be subject to any requirement of this Annex.

In accordance with Regulation 9 of Annex V of the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL 73/78) a record is to be kept of each discharge operation or completed incineration. This includes discharges at sea, to reception facilities, or to other ships.
2.Garbage and garbage management:
Garbage includes all kinds of food, domestic and operational waste excluding fresh fish and parts thereof, generated during the normal operation of the vessel and liable to be disposed of continuously or periodically except those substances which are defined or listed in other annexes to MARPOL 73/78 (such as oil, sewage or noxious liquid substances).
The Guidelines for the Implementation of Annex V of MARPOL 73/78 should also be referred to for relevant information.
3.Description of the garbage
The garbage is to be grouped into categories for the purposes of this record book as follows:
- 1.Plastics
- 2.Floating dunnage, lining, or packing material
- 3.Ground-down paper products, rags, glass, metal, bottles, crockery, etc.
- 4.Cargo residues, paper products, rags, glass, metal, bottles, crockery, etc.
- 5.Food waste
- 6.Incinerator ash
4.Entries in the Garbage Record Book
Entries in the Garbage Record Book shall be made on each of the following occasions:
- a)When garbage is discharged into the sea:
  - (i)Date and time of discharge
  - (ii)Position of the ship (latitude and longitude). Note for cargo residue discharges, include discharge start and stop positions.
  - (iii)Category of garbage discharged
  - (iv)Estimated amount discharged for each category in m³
  - (v)Signature of the officer in charge of the operation.
- b)When garbage is discharged to reception facilities ashore or to other ships:
  - (i)Date and time of discharge
  - (ii)Port or facility, or name of ship
  - (iii)Category of garbage discharged
  - (iv)Estimated amount discharged for each category in m³
  - (v)Signature of officer in charge of the operation.
- c)When garbage is incinerated:
  - (i)Date and time of start and stop of incineration
  - (ii)Position of the ship (latitude and longitude)
  - (iii)Estimated amount incinerated in m³
  - (iv)Signature of the officier in charge of the operation.

  - (iv)Circumstances of disposal, escape or loss, the reason therefore and general remarks.
4.2.Receipts
The master should obtain from the operator of port reception facilities, or from the master of the ship receiving the garbage, a receipt or certificate specifying the estimated amount of garbage transferred. The receipts or certificates must be kept on board the ship with the Garbage Record Book for two years.
4.3.Amount of garbage
The amount of garbage onboard should be estimated in m³, if possible separately according to category. The Garbage Record Book contains many references to estimated amount of garbage. It is recognized that the accuracy of estimating amounts of garbage is left to interpretation. Volume estimates will differ before and after processing. Some processing procedures may not allow for a usable estimate of volume, e.g. the continuous processing of food waste. Such factors should be taken into consideration when making and interpreting entries made in a record.

Internationaal Verdrag ter voorkoming van verontreiniging door schepen, 1973

De Partijen bij het Verdrag,

Zich bewust van de noodzaak tot behoud van het milieu in het algemeen en van het mariene milieu in het bijzonder,

Erkennend dat het opzettelijk, onachtzaam, dan wel bij ongeluk, lozen van olie en andere schadelijke stoffen door schepen een ernstige bron van verontreiniging vormt,

Voorts erkennend het belang van het Internationaal Verdrag ter voorkoming van verontreiniging van de zee door olie, 1954, als de eerste multilaterale overeenkomst die werd gesloten met de bescherming van het milieu als voornaamste oogmerk en haar waardering uitsprekende voor de belangrijke bijdrage die genoemd Verdrag heeft geleverd aan het behoeden van de zeeën en de kustgebieden voor verontreiniging,

Geleid door de wens een einde te maken aan de opzettelijke verontreiniging van het mariene milieu door olie en andere schadelijke stoffen, en de lozing bij ongeluk van dergelijke stoffen tot een minimum te beperken,

Overwegende dat dit doel het beste kan worden bereikt door het opstellen van regels met een universele strekking die niet beperkt zijn tot verontreiniging door olie,

Zijn overeengekomen als volgt:
