The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the shift in LCG if 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials?

Correct Answer: Option A — 0.06 foot aft

Longitudinal weight shifts change the LCG according to the moment formula: weight added times distance from the reference point divided by new total displacement. Adding 100.76 long tons to Ballast Tank #8S shifts the overall LCG 0.06 foot aft.
