Question 3136 Deck General

70% to pass

When oily ballast has been pumped overboard, an entry must be made in the _______________.

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

The correct answer is B) Oil Record Book. When oily ballast is pumped overboard, this must be recorded in the ship's Oil Record Book as per regulations. The Oil Record Book is the official log required by the International Convention for the Prevention of Pollution from Ships (MARPOL) to document all operations involving oil and oily mixtures on board a vessel. The deck rough log, official logbook, and engine rough log are not the proper place to record this information.
