70% to pass

The DEEP DRILLER is loaded as shown in Sample Load Form #4 (Drilling). What would be the new sum of FSML for Fresh Water if the entire contents of Drill Water Tank #5P are transferred to Tank #5S?

A 3,645 ft-tons
B 3,328 ft-tons
C 317 ft-tons
D 0 ft-tons
AI Explanation

The correct answer is C) 317 ft-tons. When the contents of Drill Water Tank #5P are transferred to Tank #5S, the total amount of fresh water remains the same, but the change in the location of the weight causes a change in the FSML (Free Surface Moment of Liquid). The FSML is reduced by 317 ft-tons, as the weight is shifted from a more forward tank to a more aft tank, reducing the moment arm. The other options are incorrect because: A) 3,645 ft-tons is the original FSML, which does not change when the water is transferred. B) 3,328 ft-tons is the incorrect FSML after the transfer. D) 0 ft-tons is incorrect, as the FSML does change due to the weight shift.
