The DEEP DRILLER is drilling at 60 feet draft at a corrected KG of 54.0 feet. Ballast added or discharged to remain at a constant draft is at a VCG of 10 feet. How much non-liquid load would have to be removed from an average height of 130 feet above the keel to meet the maximum allowable KG at a draft of 60 feet for winds greater than 70 knots?
Official USCG Answer & Rule Citation
Correct Answer: Option D — 302 long tons
Solving for required weight removal to lower the center of gravity to the maximum allowable KG limit at 60 feet draft involves moments conservation equations, indicating that 302 long tons removed from 130 feet VCG satisfies survival criteria for winds exceeding 70 knots.
