in force 6 May 1975
The States Parties to the present Convention,
Conscious of the need to protect the interests of their peoples against the grave consequences of a
maritime casualty resulting in danger of oil pollution of sea and coastlines, convinced that under these
circumstances measures of an exceptional character to protect such interests might be necessary on the
high seas and that these measures do not affect the principle of freedom of the high seas,
Have agreed as follows:
Article I
1. Parties to the present Convention may take such measures on the high seas as may be necessary to
prevent, mitigate or eliminate grave and imminent danger to their coastline or related interests from
pollution or threat of pollution of the sea by oil, following upon a maritime casualty or acts related to
such a casualty, which may reasonably be expected to result in major harmful consequences.
2. However, no measures shall be taken under the present Convention against any warship or other
ship owned or operated by a State and used, for the time being, only on government non-commercial
service.
Article II
For the purpose of the present Convention:
1. “maritime casualty” means a collision of ships, stranding or other incident of navigation, or other
occurrence on board a ship or external to it resulting in material damage or imminent threat of material
damage to a ship or cargo;
2. “ship” means:
(a) any sea-going vessel of any type whatsoever, and
(b) any floating craft, with the exception of an installation or device engaged in the exploration and
exploitation of the resources of the sea-bed and the ocean floor and the subsoil thereof;
3. “oil” means crude oil, fuel oil, diesel oil and lubricating oil;
4. “related interests” means the interests of a coastal State directly affected or threatened by the
maritime casualty, such as:
(a) maritime coastal, port or estuarine activities,
including fisheries activities, constituting an essential means of livelihood of the persons concerned;
(b) tourist attractions of the area concerned;
(c) the health of the coastal population and the well-being of the area concerned, including
conservation of living marine resources and of wildlife;
5. “Organization” means the Inter-Governmental Maritime Consultative Organization.
Article III
When a coastal State is exercising the right to take measures in accordance with Article I, the
following provisions shall apply:
(a) before taking any measures, a coastal State shall proceed to consultations with other States affected
by the maritime casualty, particularly with the flag State or States;
(b) the coastal State shall notify without delay the proposed measures to any persons physical or
corporate known to the coastal State, or made known to it during the consultations, to have interests
which can reasonably be expected to be affected by those measures. The coastal State shall take into
account any views they may submit;
(c) before any measure is taken, the coastal State may proceed to a consultation with independent
experts, whose names shall be chosen from a list maintained by the Organization;
(d) in cases of extreme urgency requiring measures to be taken immediately, the coastal State may take
measures rendered necessary by the urgency of the situation, without prior notification or consultation
or without continuing consultations already begun;
(e) a coastal State shall, before taking such measures and during their course, use its best endeavours
to avoid any risk to human life, and to afford persons in distress any assistance of which they may
stand in need, and in appropriate cases to facilitate the repatriation of ships crews, and to raise no
obstacle thereto;
(f) measures which have been taken in application of Article I shall be notified without delay to the
States and to the known physical or corporate persons concerned, as well as to the Secretary-General
of the Organization.
Article IV
1. Under the supervision of the Organization, there shall be set up and maintained the list of experts
contemplated by Article III of the present Convention, and the Organization shall make necessary and
appropriate regulations in connection therewith, including the determination of the required
qualifications.
2. Nominations to the list may be made by Member States of the Organization and by Parties to this
Convention. The experts shall be paid on the basis of services rendered by the States utilizing those
services.
Article V
1. Measures taken by the coastal State in accordance with Article I shall be proportionate to the
damage actual or threatened to it.
2. Such measures shall not go beyond what is reasonably necessary to achieve the end mentioned in
Article I and shall cease as soon as that end has been achieved; they shall not unnecessarily interfere
with the rights and interests of the flag State, third States and of any persons, physical or corporate,
concerned.
3. In considering whether the measures are proportionate to the damage, account shall be taken of:
(a) the extent and probability of imminent damage if those measures are not taken; and
(b) the likelihood of those measures being effective; and
(c) the extent of the damage which may be caused by such measures.
Article VI
Any Party which has taken measures in contravention of the provisions of the present Convention
causing damage to others, shall be obliged to pay compensation to the extent of the damage caused by
measures which exceed those reasonably necessary to achieve the end mentioned in Article I.
Article VII
Except as specifically provided, nothing in the present Convention shall prejudice any otherwise
applicable right, duty, privilege or immunity or deprive any of the Parties or any interested physical or
corporate person of any remedy otherwise applicable.
Article VIII
1. Any controversy between the Parties as to whether measures taken under Article I were in
contravention of the provisions of the present Convention, to whether compensation is obliged to be
paid under Article VI, and to the amount of such compensation shall, if settlement by negotiation
between the Parties involved or between the Party which took the measures and the physical or
corporate claimants has not been possible, and if the Parties do not otherwise agree, be submitted upon
request of any of the Parties concerned to conciliation, or if conciliation does not succeed, to
arbitration, as set out in the Annex to the present Convention.
2. The Party which took the measures shall not be entitled to refuse a request for conciliation or
arbitration under provisions of the preceding paragraph solely on the grounds that any remedies under
municipal law in its own courts have not been exhausted.
