Question 322Safety & Environmental - Assistant Engineer

The correct answer is C) unless authorized by the captain of the port. This is because the regulations set forth by the US Coast Guard prohibit a person from being in charge of oil transfer operations on more than one vessel at a time, unless the captain of the port has specifically authorized them to do so. The captain of the port has the authority to grant exceptions to this rule if they deem it necessary or appropriate. The other answer choices are incorrect because they do not align with the actual regulations. Option A is incorrect because the vessels' mooring status is irrelevant to this regulation. Option B is incorrect because radio communication alone does not provide the necessary authorization. Option D is incorrect because there are circumstances where a person can be in charge of oil transfer operations on multiple vessels, as long as they have the captain of the port's authorization.
