Question 3808 Deck General

The correct answer is B) Nearest Coast Guard Marine Safety Office. According to Coast Guard regulations, a report of casualty to a mobile offshore drilling unit must be made in writing to the nearest Coast Guard Marine Safety Office. This requirement is specified in 46 CFR 4.05-1, which states that the owner, agent, master, operator, or person in charge of a vessel must immediately notify the nearest Coast Guard Marine Safety Office whenever a vessel is involved in a marine casualty. This reporting requirement applies to mobile offshore drilling units, as they are considered vessels under Coast Guard regulations. The other answer choices are incorrect because the Commandant of the Coast Guard (A) is not the appropriate office for this type of report, the owner of the unit (C) is not the designated recipient, and the Captain of the nearest port (D) is not the correct authority for this notification.
