Question 3776 Deck General

The correct answer is C) The reason for opening or closing each appliance. The reason this is the correct answer is that the Code of Federal Regulations (CFR) requires the master or person in charge of a mobile offshore drilling unit (MODU) to enter the reason for opening or closing each watertight integrity appliance not fitted with a remote operating control or alarm system in the logbook. This requirement is specified in 46 CFR 109.503(a)(3), which states that the reason for opening and closing such appliances must be recorded. The other answer choices are incorrect because they do not align with the specific regulatory requirement. Option A is incorrect as the logbook entry is not about the hull indicators. Option B is incorrect as the name of the person performing the action is not required. Option D is incorrect as the time required to close the appliances is also not a required logbook entry for this specific situation.
