Who is responsible for insuring that each survival craft on a mobile offshore drilling unit is cleaned and inspected once a year?

Correct Answer: Option C — The designated person in charge of the rig

46 CFR 109.227 places the ultimate responsibility for the maintenance and inspection of survival craft on the person in charge. While crew members perform the physical tasks, the person in charge must ensure that these critical life-saving appliances are cleaned, inspected, and fully operational at least annually.
