Question 1 of 27070

Q

According to U.S. regulations, when a tank vessel is discharging cargo, each sea suction valve connected to the vessel's oil transfer, ballast, or cargo tank systems must be which of the following?

🔍 Key Concepts

• 33 CFR requirements for oil transfer operations and pollution prevention • The purpose of controlling sea suction valves during cargo discharge on tank vessels • How uncontrolled sea suction openings could affect pollution risk during discharge

💭 Think About

• Ask what could happen if a sea suction valve that connects to cargo or ballast systems were accidentally opened while oil cargo is being discharged • Consider which option would best ensure that no oil can accidentally be pumped or siphoned overboard through a sea connection during cargo discharge • Think about which choices are temporary operational measures versus permanent fittings, and which one the regulations specifically use for "each sea suction valve"

✅ Before You Answer

• Verify which 33 CFR Part (e.g., 33 CFR Part 155 – Oil or Hazardous Material Pollution Prevention Regulations for Vessels) covers this requirement • Check the exact wording about sea suction valves during cargo discharge – does it say must be ___ for each valve? • Confirm whether the regulation is requiring a position/condition of the valve (how it’s secured) or a fitting/device installed on the line
