In accordance with the international MARPOL Annex I regulations and the federal regulations in 33CFR Subchapter O, specific machinery space operations onboard all ships of 400 gross tons or above other than a tanker must be documented in an Oil Record Book. This includes disposal of oil residues and overboard discharge of bilge water that has accumulated in machinery spaces, as well as other operations. Who is responsible for signing the Oil Record Book entry for the specific operation?

Question

Accepted Answer

Option B: The officer in charge of the operation. According to 33 CFR 151.25, each entry in the Oil Record Book must be signed by the officer or officers in charge of the operations concerned. This ensures accountability and provides a clear audit trail for regulatory inspections, verifying that each specific machinery space operation was conducted in compliance with MARPOL standards.
