Question 3826 Deck General

The correct answer is A) on the unit. According to the regulations, a mobile offshore drilling unit crane certificate must be maintained on the unit itself. This is because the crane certificate is required to be readily available for inspection by the Coast Guard or other authorities whenever the unit is in operation. Keeping the certificate on the unit ensures that it can be quickly accessed and verified. The other answer choices are incorrect because the certificate should not be kept in the company office (B), on file with the OCMI (Officer in Charge, Marine Inspection) (C), or on file with the American Bureau of Shipping (D). The certificate must be physically present on the mobile offshore drilling unit at all times.
