Question 3815 Deck General

The correct answer is D) record the length of each abandonment drill in the rig's log book. On a mobile offshore drilling unit, the regulations require that the length of each abandonment drill be recorded in the rig's log book. This is to ensure that the crew is properly trained and can quickly and safely evacuate the rig in the event of an emergency. The other answer choices are incorrect because: A) keeping engineering spaces clean is a general requirement, not specific to mobile offshore drilling units; B) checking the Certificate of Inspection of support vessels is not a requirement for the mobile offshore drilling unit itself; and C) inspecting helicopter lifesaving gear is not a mandatory procedure for the rig.
