Question 1461 Deck General

The correct answer is C) the designated person-in-charge supervises that procedure. According to U.S. regulations, no person may connect or disconnect an oil transfer hose or engage in any other critical oil transfer operation on a tank vessel unless the designated person-in-charge supervises that procedure. This requirement is specified in the Coast Guard regulations to ensure that a qualified individual is overseeing critical oil transfer operations to maintain safety and prevent spills. The other answer choices are incorrect because: A) holding a port security card is not a requirement for conducting oil transfer operations, B) a license as master, mate, or engineer is not necessary for this specific task, and D) a tankerman assistant endorsement is not required for the designated person-in-charge to supervise the oil transfer.
