What is the new location of the longitudinal center of gravity if 200 short tons are discharged from 30 feet forward of amidships on a MODU with LCG 1.5 feet forward of amidships, and displacement 9,000 short tons?

A 0.88 foot forward of amidships
B 0.85 foot forward of amidships
C 0.82 foot forward of amidships
D 0.79 foot forward of amidships
AI Explanation

The correct answer is B) 0.85 foot forward of amidships. To calculate the new location of the longitudinal center of gravity (LCG), we can use the formula: LCG = (LCG × Displacement - Weight Removed × Distance) / Displacement. Given: - Initial LCG: 1.5 feet forward of amidships - Displacement: 9,000 short tons - Weight Removed: 200 short tons - Distance: 30 feet forward of amidships Plugging these values into the formula, we get: LCG = (1.5 × 9,000 - 200 × 30) / 9,000 = 0.85 foot forward of amidships. The other options are incorrect because they do not accurately reflect the new LCG based on the given information.
