🔍 Key Concepts

• 33 CFR Part 155 – Oil or Hazardous Material Pollution Prevention Regulations for Vessels • Specific equipment and arrangements required before oil transfer operations • The difference between requirements for normal transfers vs emergency or spill response gear

💭 Think About

• Which option describes something that must be in place and physically connected as part of the transfer system itself, rather than general safety or pollution-response equipment? • Which choices sound more like spill cleanup/response measures, and which sound like basic engineering/connection requirements for making a tight, leak‑free transfer? • Think about what the regulations are trying to prevent before a spill happens: what has to be secured so oil doesn’t leak at the interface between ship and shore/another vessel?

✅ Before You Answer

• Verify in 33 CFR that the requirement relates to fittings/connections used in the transfer and not general deck arrangements. • Check whether the regulation talks specifically about couplings or connections being secured/fastened before transfer begins. • Confirm that the distractor choices involve items that may be used in special situations (e.g., certain ports, certain vessels, or spill response) rather than a universal requirement for any oil transfer.
