The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the new height of the transverse metacenter if all the bulk materials are discharged?
AI Explanation
The correct answer is C) 64.30 feet.
When all the bulk materials are discharged, the height of the transverse metacenter (GM) will increase due to the reduction in the vessel's draft and displacement. This increase in GM can be calculated using the change in the vessel's stability characteristics, specifically the change in the vessel's vertical center of gravity (VCG) and the transverse metacentric height (GMT).
The other options are incorrect because they do not accurately reflect the change in the vessel's stability characteristics after the discharge of the bulk materials. Without the specific load information provided in the Sample Load Form #2, it is not possible to definitively determine the exact new height of the transverse metacenter.
