Question 4267 Deck General

70% to pass

The DEEP DRILLER is operating at a draft of 60 feet. There is 11.5 feet of drill water in each of the drill water tanks (5P and 5S). What would be the improvement in KGL if 5S is filled from 5P?

A 0.56 foot
B 0.49 foot
C 0.18 foot
D 0.08 foot
AI Explanation

The correct answer is D) 0.08 foot. The improvement in KGL (Longitudinal Metacentric Height) when filling 5S from 5P would be 0.08 foot. This is because the shift in weight from one side to the other does not significantly affect the overall stability of the vessel, as the weight is relatively small compared to the overall displacement of the DEEP DRILLER. The other answer choices are incorrect because they overestimate the impact of this small weight shift on the vessel's stability. The change in KGL would be negligible, as the weight of the drill water is insignificant compared to the vessel's total displacement.
