Question 3135 Deck General

70% to pass

When oil is discharged overboard, an entry is required in the _______________.

A engine rough log
B deck rough log
C Oil Record Book
D Official Logbook
AI Explanation

The correct answer is C) Oil Record Book. When oil is discharged overboard, either intentionally or accidentally, regulations require that an entry be made in the vessel's Oil Record Book. This is a requirement under Annex I of the International Convention for the Prevention of Pollution from Ships (MARPOL), which applies to all commercial vessels. The Oil Record Book is the official log where all oil-related operations, including discharges, must be documented. The engine rough log, deck rough log, and official logbook do not serve this specific purpose for recording oil discharges.
