The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Weather conditions require ballasting to survival draft. Assume that 4087 long tons of ballast are added at an average VCG of 8.32 feet. What would be the value of uncorrected KG?

Correct Answer: Option A — 51.65 feet

Uncorrected vertical center of gravity (KG) after weight addition is determined using moments. Multiply initial displacement by initial VCG, add the product of added ballast weight (4087 tons) and its VCG (8.32 feet), then divide the total moment by the new total displacement.
