🔍 Key Concepts

• 33 CFR oil pollution regulations dealing with oil transfer and discharge • Required official log or record for oil transfers on certain vessels • Difference between a general ship’s log and a specialized pollution/engineering record

💭 Think About

• Ask yourself: when oil is transferred or discharged, which document is specifically REQUIRED by pollution regulations, not just commonly used on board? • Which of these choices is an official, standardized book required by regulation on certain vessels, rather than something each company or master might name differently? • Think about where engineers normally document tank-to-tank transfers, sludge discharge, and bilge water handling: is it a bridge document or an engineering/pollution-control document?

✅ Before You Answer

• Verify which item in the choices is explicitly named in 33 CFR as the place to record oil transfers and discharges. • Check whether the bridge log or master’s log are usually mentioned in oil pollution rules, or if they are used more for navigating and voyage events. • Confirm which option sounds like a formal regulatory record rather than an informal or company‑specific log.
