🔍 Key Concepts

• 33 CFR Part 156 – Oil Transfer Operations and its purpose (preventing spills during transfers) • What must be agreed upon and documented in the pre‑transfer conference / Declaration of Inspection before starting the transfer • The difference between conditions that apply to every transfer vs. special/optional practices (like sampling or hose draining)

💭 Think About

• Ask yourself: which option is a regulatory precondition that must be in place before any oil transfer can lawfully begin, regardless of cargo type or hose condition? • Look at each choice and decide: is this something that would mainly happen after transfer, only in some situations, or always before transfer? • Think about spill prevention: which of these, if not done, would most directly increase the risk of overpressure, hose failure, or overflow during the transfer itself?

✅ Before You Answer

• Verify in 33 CFR 156.120 and 156.150 what items must be agreed upon by the persons in charge before starting transfer operations. • Check which items are explicitly listed on the Declaration of Inspection as mandatory for oil transfers. • Confirm whether the regulation talks about flow rate/pressure control versus things that may be good practice but are not stated as universal legal requirements.
