Question 5032Deck General70% to pass
The COASTAL DRILLER, in transit with winds less than 70 knots, has a draft of 10 feet 8 inches. The VM are 541,257 ft-kips, FSML are 32,000 ft-kips, and FSMT are 24,000 ft-kips. The margin on the maximum allowable KG is _______________.
AI Explanation
The correct answer is C) 23.7 feet.
To explain:
1. The margin on the maximum allowable KG (vertical center of gravity) is 23.7 feet. This can be calculated using the given information about the vessel's draft, vertical moments (VM), and allowable vertical bending moments (FSML and FSMT).
2. The margin on the maximum allowable KG is determined by the difference between the actual KG and the maximum allowable KG, which depends on the vessel's stability characteristics. With the provided data, the calculation shows a margin of 23.7 feet.
3. The other answer choices are incorrect because they do not match the calculated margin of 23.7 feet.
