🔍 Key Concepts

• 33 CFR Part 155 – Oil or hazardous material pollution prevention regulations for vessels • Specific requirements for oil transfer operations, including personnel, equipment, and procedures • The purpose and requirement level of discharge containment equipment (drip pans, sorbents, etc.) during transfers

💭 Think About

• Ask yourself which of these choices is a regulatory requirement for every oil transfer on most U.S. vessels, and which are only sometimes required or not required at all. • Consider whether two certificated tankermen are always required, or whether manning requirements can vary by vessel type, size, and route. • Think about whether constant-tension winches are a pollution-prevention requirement, or more related to cargo handling/mooring gear.

✅ Before You Answer

• Verify in 33 CFR Part 155, Subpart B what must be in place before starting any oil transfer, especially regarding discharge containment. • Check if the regulations always require two certificated tankermen on each vessel, or if the rules are more flexible depending on the operation. • Confirm whether the regulations anywhere state that constant-tension winches are a prerequisite for transferring oil.
