Issued under provision of
International Convention on Civil Liability for Oil Pollution Damage (CLC)
It is an evidence issued by flag state that the vessel is P&I insured to cover damage from pollution by oil
Requirements for wreck removal certificate are:
The 1992 Protocol allows for States Party to the 1992 Protocol to issue certificates to ships registered in States which are not Party to the 1992 Protocol, so that a shipowner can obtain certificates to both the 1969 and 1992 CLC, even when the ship is registered in a country which has not yet ratified the 1992 Protocol. This is important because a ship which has only a 1969 CLC may find it difficult to trade to a country which has ratified the 1992 Protocol, since it establishes higher limits of liability.
