Question 4278 Deck General

The correct answer is A) 6.5%. In storm conditions with high winds and waves, the offset of the DEEP DRILLER in 600 feet of water depth is initially 9%. By completely slacking mooring lines 5 and 6, the offset is reduced to 6.5%. This is because slacking the mooring lines reduces the restraining force on the vessel, allowing it to drift and reduce the overall offset from its original position. The other options are incorrect because: B) 5.0% is too low of an offset reduction, C) 2.5% is even lower and unlikely, and D) 0.0% would be an unrealistic complete elimination of the offset in these storm conditions.
