Question 4469 Deck General
70% to passIn storm conditions, with the wind and waves from the port bow of the DEEP DRILLER in 600 feet water depth, the tensions in mooring line 1 and 2 are 400 kips. Completely slacking the mooring lines 5 and 6 reduces the tension in mooring lines 1 and 2 to about _______________.
The correct answer is B) 330 kips. When the vessel is moored in storm conditions, the tensions in the mooring lines are affected by the wind and waves acting on the vessel. Slacking the mooring lines 5 and 6 reduces the tension in mooring lines 1 and 2, as this redistributes the forces acting on the vessel. The reduction in tension is typically around 17-20% of the initial tension, which in this case would result in a tension of approximately 330 kips in mooring lines 1 and 2. The other options are incorrect because A) 375 kips is too high, C) 275 kips is too low, and D) 220 kips is also too low compared to the expected reduction in tension.
