🔍 Key Concepts

• MARPOL (International Convention for the Prevention of Pollution from Ships) requirements for Oil Record Books • Difference between tankers and passenger/cargo ships in pollution-prevention thresholds • How gross tonnage thresholds trigger different equipment and record-keeping requirements

💭 Think About

• Think about which size of passenger vessels the regulations start to treat as a significant pollution risk for oil discharges. • Recall whether the Oil Record Book requirement begins at the same tonnage for all ships, or if smaller ships are treated differently. • Ask yourself if this tonnage threshold sounds more like one used for safety equipment or for pollution prevention documentation.

✅ Before You Answer

• Verify in MARPOL Annex I or the corresponding sections of 46 CFR what gross tonnage threshold is specified for passenger ships required to keep an Oil Record Book. • Confirm whether the same tonnage threshold applies to all ships other than oil tankers when it comes to Oil Record Books. • Check that you are not confusing tonnage cutoffs used for lifesaving appliances or fire protection with those used for pollution-prevention recordkeeping.
