INTERNATIONAL CONVENTION RELATING TO INTERVENTION ON  
THE HIGH SEAS IN CASES OF OIL POLLUTION CASUALTIES 

(Brussels, 29 November 1969) 

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, onvinced 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 connexion 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.

to the damage, account shall be taken of: 

(a) the extent and probability of imminent damage if

and  
(c) the extent of the damage which may be caused by such  
measures. 

Article VI

those reasonably necessary to achieve the end mentioned  
in Article I.

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
