What does the Oil Record Book document?

• A. Garbage Record Book
• B. All oil transfer operations and discharge of oil or oily mixtures.
• C. Ballast Water Management Record
• D. Cargo Manifest and Logs

Answer: (B)

The Oil Record Book tracks all oil-related operations and any discharge of oil or oily mixtures from the ship. This keeps a clear, traceable record of activities that could pollute the sea, such as loading or unloading oil cargo, transferring oil between tanks, ballasting or deballasting with oil-containing ballast, tank washing, and discharges of oily water from the machinery spaces or any oily residues. It’s a requirement under MARPOL Annex I for ships that carry oil in bulk or operate with oil-containing systems, and it’s what inspectors use to verify that oil management and pollution prevention procedures were followed. Other records exist for different purposes—Garbage Record Book covers garbage, Ballast Water Management Record covers ballast water treatment and discharges, and Cargo Manifest and Logs pertain to general cargo operations—so the Oil Record Book is specifically about oil-related transfers and discharges.
