Question 4264 Deck General

The correct answer is B) 5.0%. In storm conditions, with the wind and waves from the starboard bow of the DEEP DRILLER in 600 feet water depth, the offset is 8%. Completely slacking mooring lines 7 and 8 reduces the offset to 5.0%. This is because slacking the mooring lines reduces the tension on the vessel, allowing it to move more freely and reduce the offset in the storm conditions. The other options are incorrect because: A) 6.5% is too high of an offset after slacking the mooring lines. C) 2.5% is too low of an offset and would be an unrealistic reduction. D) 0.0% is not possible, as the vessel would still have some offset even with completely slacked mooring lines.
