🔍 Key Concepts

• MARPOL Annex I requirements for the Oil Record Book (Part I – Machinery Space Operations) • Types of operations that involve movement, transfer, or potential discharge of oil versus routine maintenance/inspection • Examples of operations explicitly listed in the Oil Record Book format, such as ballasting/cleaning of fuel tanks, bilge discharge, and fuel transfers

💭 Think About

• Look at each choice and ask: does this operation actually move, transfer, or potentially discharge oil, or is it just checking/adjusting equipment? • Which of these operations is most similar to the examples you see printed in the standard Oil Record Book pages for machinery space operations? • Think about which action would be important for port state control or flag state to trace if there’s ever an oil pollution investigation.

✅ Before You Answer

• Verify which option involves fuel oil tanks being filled, emptied, or cleaned, not just inspected or adjusted. • Check the standard list of machinery space operations that must be recorded (e.g., ballasting/cleaning fuel oil tanks, discharge of bilge water, sludge operations). • Confirm that routine inspections or valve/plate adjustments without actual oil transfer are generally not recorded in the Oil Record Book.
