The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of 6 and 7 drill water tanks are discharged, what is the new height of the center of gravity corrected for transverse free surface effects?

Correct Answer: Option C — 50.82 feet

Calculating the final vertical center of gravity (VCG) after discharging fluid requires taking the final solid VCG and adding the free surface correction (FSC), which increases the effective height of the center of gravity due to liquid shift moments.
