To avoid excessive pressures in the fuel oil filling system during bunkering, you should __________.

Correct Answer: Option A — reduce the loading rate when topping off

Reducing the loading rate during the topping-off phase is a standard operational safety procedure. It allows the crew sufficient time to monitor tank levels, adjust valves, and prevent pressure surges or accidental overflows, which are most likely to occur when tanks reach their maximum capacity during bunkering operations.
