Ballast Waster Management

If a vessel is built with a BWTS before BWM Convention entered into force, and the BWMP states that the vessel complies with both the D-1 and D-2 Standards, after the first IOPP Renewal when the vessel must comply only with the D-2 Standard, should the BWMP be updated also?


In a D2 vessel the BWMP can still mention both the D1 and D2 standards. D1 (ballast exchange) can be a contingency measure, provided that the Flag and Port authorities accept it.
