🔍 Key Concepts

• 33 CFR Part 155 requirements for oil transfer procedures on tank vessels • Specific items that must be written into transfer procedures (person in charge, line diagrams, emergency/operational steps) • The purpose of deck containment systems versus operating/transfer procedures

💭 Think About

• Look up what 33 CFR says must be written in the vessel’s oil transfer procedures and compare each option to that list. • Ask yourself which option describes something that is more of a physical arrangement or equipment description than a step-by-step procedure. • Consider which items are directly related to how the transfer is conducted and controlled, especially near the end of the transfer (topping off).

✅ Before You Answer

• Verify in 33 CFR 155 what elements are explicitly required in the written transfer procedures. • Check whether the person in charge and piping diagrams are specifically mentioned in the regulation as required content. • Confirm whether a deck discharge containment system description is treated as a required part of the written procedures or addressed separately under equipment/arrangement requirements.
