A semisubmersible displacing 17,600 long tons has an LCG 3.2 feet forward of amidships. Bulk, weighing 400 long tons, is loaded into P-tanks located 50.8 feet aft of amidships. What is the new LCG?

Correct Answer: Option C — 2.00 feet forward of amidships

Loading weight into P-tanks aft creates a longitudinal moment change. Dividing the net moment change by the new total displacement shifts the LCG from 3.2 feet forward to a new position of 2.00 feet forward of amidships.
