Question 952 Deck General

The correct answer is C) close valves by closing them down, reopening one or two turns, and re-closing. This is the correct procedure when loading a tanker to avoid sudden pressure surges that can damage the loading equipment. Closing the valves completely can lead to a sudden pressure increase, so it's recommended to close them down, reopen them slightly, and then re-close to gradually reduce the pressure. This helps maintain a controlled, steady flow during the loading process. The other options are incorrect because: A) loading only one tank at a time is overly restrictive, B) keeping a strain on the hoses is not the primary concern, and D) keeping seamen on standby is not directly related to the valve operation procedure.
