The DEEP DRILLER, loaded as shown in the Sample Load Form #4 (Drilling), discharges a non-liquid load of 275.8 long tons from a position 130 feet above the keel, 40 feet forward of amidships, and 30 feet to port of the centerline. What is the improvement in KGL?
AI Explanation
The correct answer is C) 1.15 feet.
The improvement in KGL (the height of the center of gravity above the keel) is calculated by using the formula: KGL = (Load x Moment)/Displacement. In this case, the non-liquid load of 275.8 long tons discharged from a position 130 feet above the keel, 40 feet forward of amidships, and 30 feet to port of the centerline, results in a moment of 4,583.3 foot-long tons. Plugging this into the formula, the improvement in KGL is 1.15 feet.
The other answer choices are incorrect because they do not accurately reflect the calculation using the provided information. Answer A (0.67 foot) and Answer B (0.98 foot) are too low, while Answer D (2.06 feet) is too high.
