Question 1 of 27070

Q

Which of the following represents an emergency procedure used to stop the oil flow aboard tank vessels, of 250 tons or greater, as required by U.S. regulations?

🔍 Key Concepts

• 46 CFR requirements for emergency shutdown systems on tank vessels of 250 gross tons or more • How oil flow is normally stopped in cargo transfer emergencies (think: remote vs local control) • Difference between manual, self-closing, pressure-sensitive, and power-actuated devices

💭 Think About

• Which option reflects a device specifically required by regulation for EMERGENCY stopping of cargo oil flow, not just routine control? • In an emergency, where might crew need to operate the shutdown from—right next to the valve, or from a safer remote location? • Which type of device is commonly tied into an emergency shutdown system used during cargo transfer operations?

✅ Before You Answer

• Verify what 46 CFR Part 32 and related sections say about emergency shutoff valves on tank vessels ≥ 250 gross tons • Check whether the regulation emphasizes remote operation of the shutdown device • Confirm which listed device is normally associated with cargo oil transfer emergency shutdown systems, not pressure control or automatic fittings
