70% to pass

How long shall the Master or person in charge of a MODU maintaining an unofficial logbook retain this logbook on board?

A 6 months
B 1 year
C 5 years
D Until the next inspection for certification
AI Explanation

The correct answer is D) Until the next inspection for certification. The reasoning for this is that under U.S. Coast Guard regulations, the master or person in charge of a Mobile Offshore Drilling Unit (MODU) must maintain an unofficial logbook onboard. This logbook must be retained on the MODU until the next inspection for certification, which typically occurs annually. The other options (6 months, 1 year, 5 years) do not align with the Coast Guard's requirements for maintaining these types of logbooks on MODUs.
