Question 3588 Deck General

The correct answer is D) The person in charge. On a mobile offshore drilling unit, the person in charge is responsible for maintaining the logbook. This is in accordance with US Coast Guard regulations, which require the individual in command or charge of the vessel to be responsible for the vessel's logbook and proper record-keeping. The other options are incorrect because the rig superintendent, safety man, and driller are not the designated person in charge of the overall vessel operations and record-keeping. The person in charge, typically the master or captain, holds the ultimate responsibility for the logbook on a mobile offshore drilling unit.
