The bunker certificate concerns liability insurance in connection with pollution damage caused by bunker oil. Danish ships with a gross tonnage of or above 1,000 must have the certificate. The certificate requirement also applies to foreign ships with a gross tonnage of or above 1,000 that intend to call at Danish ports, Danish places of loading or unloading, in the Danish continental shelf area or that intend to operate on a permanent basis in Danish territorial waters.
The Danish Maritime Authority issues the certificate on the basis of an application from the shipping company. The application must, inter alia, inform about the ship's insurance.
