While loaded as shown in the DEEP DRILLER Sample Load Form #4 (Drilling), all of the liquid mud is dumped. What is the new position of the longitudinal center of buoyancy?

Correct Answer: Option D — 2.29 feet

Removing weight from the vessel shifts the center of buoyancy opposite to the removed mass vector. Utilizing the DEEP DRILLER stability booklet and hydrostatic tables for Sample Load Form #4, discharging all liquid mud recalculates the underwater volume geometry, resulting in a new LCB of 2.29 feet.
