Question 4466 Deck General
70% to passIn storm conditions, with the wind and waves from the starboard bow of the DEEP DRILLER in 400 feet water depth, the offset is 7%. Completely slacking mooring lines 7 and 8 reduces the offset to _______________.
A
6.5%
B
5.0%
C
4.0%
D
2.5%
AI Explanation
The correct answer is C) 4.0%. In storm conditions, with the wind and waves from the starboard bow of the DEEP DRILLER in 400 feet water depth, the offset is 7%. By completely slacking mooring lines 7 and 8, the offset is reduced to 4.0%. This is because slacking the mooring lines reduces the tension on the vessel, allowing it to move more freely and minimize the offset in the storm conditions. The other answer choices are incorrect because 6.5% is still too high of an offset, 5.0% is not low enough, and 2.5% would be an unrealistic reduction in offset for just slacking two mooring lines.
