Question 4398 Deck General

The correct answer is A) KGT. Adding the transverse free surface correction to the uncorrected height of the center of gravity of a MODU (Mobile Offshore Drilling Unit) yields the corrected height of the center of gravity, known as KGT. The transverse free surface correction accounts for the effect of free surfaces of liquids within the MODU's tanks, which can raise the center of gravity and impact the vessel's stability. The other options are incorrect because: B) FSCT is the transverse free surface correction itself, not the result of adding it to the uncorrected KG; C) GMT is the corrected metacentric height, which is a different stability parameter; and D) KG is the uncorrected height of the center of gravity, before the free surface correction is applied.
