Question 3131 Deck General

You are correct, the answer is A) Master. Under normal operating conditions aboard a ship, the master (captain) has the overall responsibility for maintaining the Oil Record Book. This is because the master is the person in command of the vessel and is ultimately responsible for all operations and record-keeping on board, including the Oil Record Book, which is a required log of all operations related to the handling of oil and oily waste. The other options are incorrect because the chief engineer, chief mate, and first assistant engineer, while having important responsibilities related to the vessel's engineering and deck operations, do not have the same overarching responsibility for the entire ship's operations and record-keeping as the master.
