Q

U.S. regulations require an emergency means of stopping the flow of oil or LNG during transfer operations. The emergency means may be which of the following?

🔍 Key Concepts

• 46 CFR requirements for emergency shutdown during oil or LNG transfer • Location and method of operation for emergency shutdown devices • Difference between automatic devices and emergency stop devices that require human action

💭 Think About

• Ask yourself: During a hose or loading arm failure, what type of device would the PIC (person in charge) realistically use to stop the flow of cargo quickly and reliably? • Think about where an emergency stop must be located and how it must be operated according to transfer regulations in 46 CFR (e.g., near the manifolds/cargo deck). • Consider which option matches the idea of a positive "stop the flow now" action versus something that only regulates or moderates flow.

✅ Before You Answer

• Verify in 46 CFR Part 39 (LNG) and 46 CFR Part 154/155 (oil transfers) what is specifically called an "emergency shutdown" or "emergency means of stopping the flow". • Check whether the regulation stresses a simple, clearly identifiable device that can be quickly operated in an emergency, even if power is lost. • Confirm whether the rule is talking about a control/actuator for stopping cargo flow, versus a fitting or regulator that operates automatically under certain conditions.
