Question 3788 Deck General

The correct answer is B) 3 months. Regulations require certain records related to a casualty on a mobile offshore drilling unit (MODU) to be retained on board for at least 3 months after the report of the casualty. This is specified in the Code of Federal Regulations (CFR) Title 46, Section 109.415, which states that records related to a casualty must be retained for "3months after the casually is reported." The other options are incorrect because 1 month is too short (per the regulations), 6 months is longer than the required 3-month retention period, and 12 months exceeds the regulatory requirement.
