Deck General USCG Question #3431 (Set 109)

Consideration should be given in planning for the mooring orientation in a new location so that in adverse weather a crane is available to off-load the supply vessel on what side of the unit?

Official USCG Answer & Rule Citation

Correct Answer: Option C — Leeward side

Proper mooring orientation ensures that supply vessels operate on the leeward side of the mobile offshore drilling unit. This protects transfer operations and crane utility from direct wind, wave action, and adverse weather loads, maintaining safe handling conditions under standard offshore seamanship guidelines.
