While the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches, a severe storm is predicted within 12 hours. VM are 520,462 ft-kips, FSML are 26,000 ft-kips, and FSMT are 25,000 ft-kips. How much should the KG corrected for free surface effects be lowered to satisfy the maximum allowable KG criteria?

A 26.90 feet
B 25.00 feet
C 1.90 feet
D 0.00 feet
AI Explanation

The correct answer is D) 0.00 feet. The question states that the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches. Since the vessel is in transit, it is not considered to have free surface effects, and therefore the KG does not need to be corrected for free surface effects. The maximum allowable KG criteria can be satisfied without any lowering of the KG. The other answer choices are incorrect because they suggest a lowering of the KG, which is not necessary in this case since the vessel is in transit and not subject to free surface effects.
