Question 4465 Deck General

The correct answer is B) 275 kips. In storm conditions, when the DEEP DRILLER is in 600 feet of water depth and the high-line tension (HLT) is 350 kips, completely slacking the two leeward mooring line tensions will reduce the HLT to 275 kips. This is because reducing the leeward mooring line tensions will decrease the overall restoring forces acting on the vessel, resulting in a lower HLT. The other options are incorrect because: A) 375 kips is too high, as slacking the leeward mooring lines should reduce the HLT; C) 245 kips and D) 220 kips are too low, as the HLT should not be reduced by that much when only the leeward mooring line tensions are slacked.
