Question 2594 Deck General

The correct answer is D) a tankerman-PIC endorsement. To serve as the person in charge of transfer operations on a self-propelled tank vessel, an individual must hold a tankerman-PIC (person in charge) endorsement. This endorsement is required by regulations to ensure the individual has the necessary training, knowledge, and qualifications to safely oversee the loading, unloading, and transfer of cargo on a tank vessel. The other options, such as holding an officer credential or being a certain age, are not sufficient to serve in this role - the tankerman-PIC endorsement is the specific credential required.
