Question 200Safety & Environmental - 1st Asst/Chief

The correct answer is B) person in charge. During topping off of bunker tanks, the loading rate must be personally supervised by the person in charge. This is because the person in charge, typically the master or captain of the vessel, is responsible for the overall safe operation and handling of the vessel, including fuel loading procedures. The person in charge has the authority and knowledge to ensure the proper loading rate is maintained to prevent spills or other hazardous situations. The other options are incorrect because the terminal operator may not be present on the vessel, the chief engineer is not the person ultimately responsible for the vessel's operations, and the master is the person in charge, not a separate role.
