What is the typical content required in the Oil Record Book for bilge water?

• A. Only the time of bilge water generation.
• B. Bilge water generation and discharge, OWS operation, and any transfers.
• C. The total fuel on board.
• D. The vessel speed.

Answer: (B)

The key idea here is how bilge water, an oily mixture from machinery spaces, is tracked and documented to prove MARPOL compliance. The Oil Record Book for bilge water is meant to capture the full handling of that bilge water: when it is generated in the ship’s spaces, what happens to it (whether it is transferred to another tank or treated), and whether any discharge to sea occurred. It also records the operation of the oily-water separator, including when it starts and stops and any relevant measurements or notes about its performance. Logging transfers is important because bilge water might be moved to a holding tank or routed through the OWS before any discharge, and authorities need to see the complete path from generation to final disposition. Choices that focus on total fuel on board or vessel speed don’t describe bilge-water handling and therefore aren’t part of the bilge-water entries in the Oil Record Book.
