While loaded as shown in Sample Load Form #5 (Survival), an estimated 250 long tons of snow and ice accumulates on the DEEP DRILLER at an estimated height of 127 feet. Assuming no corrective ballasting, what is the rise in the height of the center of gravity corrected for longitudinal free surface effects?

Question

Accepted Answer

Option C: 1.03 feet. Topweight accumulation such as ice increases the vessel's vertical center of gravity. Adding 250 long tons at an elevation of 127 feet on the DEEP DRILLER raises the height of the center of gravity by 1.03 feet after accounting for free surface effects.
