Question 4674 Deck General

The correct answer is C) 62.35 feet. When the DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival) and all the bulk materials are discharged, the height of the longitudinal metacenter will increase. This is because the removal of the heavy bulk materials will reduce the vessel's draft and increase the vessel's metacentric height (GM). The formula for calculating the longitudinal metacenter height (KM) is KM = KB + BM, where KB is the height of the center of buoyancy and BM is the transverse metacentric radius. With the reduced draft, the value of BM will increase, resulting in a higher KM value, which in this case is 62.35 feet. The other options are incorrect because they do not accurately reflect the change in the longitudinal metacenter height due to the discharge of the bulk materials.
