Question 3694 Deck General

The correct answer is B) owner or his agent. The designation of the person-in-charge of a mobile offshore drilling unit is the responsibility of the owner or their authorized agent, as per the regulations governing these types of vessels. The Coast Guard and the Minerals Management Service (now Bureau of Safety and Environmental Enforcement) do not directly designate the person-in-charge, but they do have regulatory oversight over the mobile offshore drilling unit and its operations. The other options are incorrect because the operator or their agent, as well as the Coast Guard and the Minerals Management Service, do not have the authority to directly designate the person-in-charge of a mobile offshore drilling unit. This responsibility lies with the owner or their authorized representative.
