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 would be the new height of the transverse metacenter?

Correct Answer: Option C — 136.38 feet

Removing liquid loads from drill water tanks changes the vessel's displacement and vertical center of gravity. Using hydrostatic curves and stability booklets, recalculating the vertical center allows determination of the transverse metacenter height, establishing a new KM of 136.38 feet.
