Question 4749 Deck General

You are correct, the answer is A) an off-center TCG. An inclined semisubmersible with a very short rolling period about a constant angle of list is likely to have an off-center TCG (Transverse Center of Gravity). This is because the vessel's stability characteristics are altered due to the inclined position, which can shift the TCG away from the vessel's centerline. The other options are incorrect because: B) a negative GM (Metacentric Height) is not a likely characteristic of this type of vessel; C) an LCG (Longitudinal Center of Gravity) greater than the level vessel's LCB (Longitudinal Center of Buoyancy) is not directly related to the given scenario; and D) excessive free surfaces are not necessarily a characteristic of an inclined semisubmersible with a short rolling period.
