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 Polution 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:

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 Convention.

2. Unless expressly provided otherwise, a referrence to the present Convention constitutes at the same time a reference to its Protocol and to the Annexes.

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 sea-bed mineral resources; or

(iii) release of harmful substances for purpose 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.

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 practiable, with the present Convention.

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 Adminsitration 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 therefore under the law of that Party. Whenever and violation occurs, the 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 discharge violations of the present Convention and shall be equally severe irrespective of where the violations occur.

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 verfying 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 proceedings 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.
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 had discharged harmful 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.
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, 6 of the present Convention, it shall be entitled to 
compensation for any loss or damage suffered.

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.

supersedes the International Convention for the Prevention 
of Pollution of the Sea by Oil, 1954, as amended, as between

legal views of any State concerning the law of the sea and 
the nature and extent of coastal and flag State 
jurisdiction.

be construed in the light of international law in force at 
the time of application or interpretation of the present 
Convention.

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

is stationary into clean calm water on a clear day would not 
produce visible traces of oil on the surface of the water or 
upon adjoining shorelines or cause a sludge or emulsion to 
be deposited beneath the surface of the water or upon 
adjoining shorelines. If the ballast is discharged through 
an oil discharge monitoring and control system approved by 
the Administration, evidence based on such a system to the 
effect that the oil content of the effluent did not exceed

assigned number freeboard and the lightweight of the ship.
23. "Lightweight" means the displacement of a ship in metric 
tons without cargo, oil fuel, lubricating oil, ballast 
water, fresh water and feedwater in tanks, consumable 
stores, passengers and their effects.
24. "Permeability" of a space means the ratio of the volume 
within that space which is assumed to be occupied by water

the present Convention is carried in a cargo space of an oil 
tanker, the appropriate requirements of Annex II of the 
present Convention shall also apply.
4. a) Any hydrofoil, air-cushion vehicle and other new type 
of vessel (near-surface craft, submarine craft, etc) whose 
constructional features are such as to render the 
application of any of the provisions of Chapters II and III 
of this Annex relating to construction and equipment 
unreasonable or impracticable may be exempted by the

before the Certificate required under Regulation 5 of this 
Annex is issued for the first time, which shall include a 
complete survey of its structure, equipment, fittings, 
arrangements and material in so far as the ship is covered 
by this Annex. This survey shall be such as to ensure that 
the structure, equipment, fittings, arrangements and 
material fully comply with the applicable requirements of 
this Annex.
b) Periodical surveys at intervals specified by the 
Administration, but not exceeding five years, which shall be 
such as to ensure that the structure, equipment, fittings, 
arrangements and material fully comply with the applicable 
requirements of this Annex. However, where the duration of 
the International Oil Pollution Certificate (1973) is 
extended as specified in Regulation 8 (3) or (4) of this 
Annex, the interval of the periodical survey may be extended 
correspondingly.
c) Intermediate surveys at intervals specified by the 
Administration but not exceeding thirty months, which shall 
be such as to ensure that the equipment and associated pump 
and piping systems, including oil discharge monitoring and 
control systems, oily-water separating equipment and oil 
filtering systems, fully comply with the applicable 
requirements of this Annex and are in good working order. 
Such intermediate surveys shall be endorsed on the 
International Oil Pollution Prevention Certificate (1973) 
issued under Regulation 5 of this Annex.
2. The Administration shall establish appropriate measures 
for ships which are not subject to the provisions of 
paragraph (1) of this Regulation in order to ensure that the 
applicable provisions of this Annex are complied with.

provisions of this Annex shall be carried out by officers of 
the Administration. The Administration may, however, entrust 
the surveys either to surveyors nominated for the purpose or 
to organizations recognized by it. In every case the 
Administration concerned fully guarantees the completeness 
and efficiency of the surveys.
4. After any survey of the ship under this Regulation has 
been completed, no significant change shall be made in the 
structure, equipment, fittings, arrangements or material 
covered by the survey without the sanction of the 
Administration, except the direct replacement of such 
equipment or fittings.
1. An International Oil Pollution Certificate (1973) shall 
be issued, after survey in accordance with the provisions of 
Regulation 4 of this Annex, to any oil tanker of 150 tons 
gross tonnage and above and any other ships of 400 tons 
gross tonnage and above which are engaged in voyages to 
ports or off-shore terminals under the jurisdiction of other 
Parties to the Convention. In the case of existing ships 
this requirement shall apply twelve months after the date of 
entry into force of the present Convention.
2. Such Certificate shall be issued either by the 
Administration or by any persons or organization duly 
authorized by it. In every case the Administration assumes 
full responsibility for the Certificate.
1. The Government of a Party to the Convention may, at the 
request of the Administration, cause a ship to be surveyed 
and, if satisfied that the provisions of this Annex are 
complied with, shall issue or authorize the issue of an 
International Oil Pollution Prevention Certificate (1973) to 
the ship in accordance with this Annex.
2. A copy of the Certificate and a copy of the survey report 
shall be transmitted as soon as possible to the requesting 
Administration.
3. A Certificate so issued shall contain a statement to the 
effect that it has been issued at the request of the 
Administration and it shall have the same force and receive 
the same force and receive the same recogimition as the 
Certificate issued under Regulation 5 of this Annex.
4. No International Oil Pollution Prevention Certificate 
(1973) shall be issued to a ship which is entitled to fly 
the flag of a State which is not a Party.
The International Oil Pollution Prevention Certificate 
(1973) shall be drawn up in an official language of the 
issuing country in the form corresponding to the model given 
in Appendix II to this Annex. If the language used is 
neither English nor French, the text shall include a 
translation into one of these languages.
1. An International Oil Pollution Prevention Certificate 
(1973) shall be issued for a period specified by the 
Administration, which shall not exceed five years from the 
date of issue, except as provided in paragraphs (2), (3) and 
(4) of this Regulation.
2. If a ship at the time when the Certificate expires is not 
in a port or off-shore terminal under the jurisdiction of 
the Party to the Convention whose flag the ship is entitled 
to fly, the Certificate may be extended by the 
Administration, but such extension shall be granted only for 
the purpose of allowing the ship to complete its voyage to 
the State whose flag the ship is entitled to fly or in which 
it is to be surveyed and then only in cases where it appears 
proper and reasonable to do so.
3. No Certificate shall be thus extended for a period longer 
than five months and a ship to which such extension is 
granted shall not on its arrival in the State whose flag it 
is entitled to fly or the port in which it is to be 
surveyed, be entitled by virtue of such extension to leave 
that port or State without having obtained a new 
Certificate.
4. A Certificate which has not been extended under the 
provisions of paragraph (2) of this Regulation may be 
extended by the Administration for a period of grace of up 
to one month from the date of expiry stated on it.

7. Upon transfer of a ship to the flag of another Party, the 
Certificate shall remain in force for a period not exceeding 
five months provided that it would not have expired before 
the end of that period, or until the Administration issues a 
replacement Certificate, whichever is earlier. As soon as 
possible after the transfer has taken place the Government 
of the Party whose flag the ship was formerly entitled to 
fly shall transmit to the Administration a copy of the 
Certificate carried by the ship before the transfer and, if 
availbale, a copy of the relevant survey report.
