Question 4985 Deck General
70% to passThe COASTAL DRILLER, with no list, is at a true mean draft of 10 feet and 10 inches. LM is 1,699,463 ft-kips. Using only tanks 1, 25, and 26, how many kips of drill water must be transferred to level the jack-up?
A
Transfer 106.2 kips aft from 1 to 25 and 26
B
Transfer 53.1 kips each from 25 and 26 forward to 1
C
Transfer 612 kips from 25 to 26
D
Vessel is level; no need to transfer
AI Explanation
The correct answer is B) Transfer 53.1 kips each from 25 and 26 forward to 1. To level the jack-up vessel, the goal is to transfer weight to reduce the list or trim. Since the vessel has no list, the issue is to reduce the trim. By transferring 53.1 kips of drill water from the aft tanks 25 and 26 to the forward tank 1, the trim will be reduced, bringing the vessel to an even keel. The other options are incorrect because: A) transferring 106.2 kips aft would increase the trim; C) transferring 612 kips from 25 to 26 would not affect the trim; and D) the vessel is not level, so weight must be transferred to level it.
