Question 4696Deck General70% to pass
A semisubmersible which flops between forward and aft angles of trim is likely to have _______________.
AI Explanation
The correct answer is D) KML less than KGL.
A semisubmersible that flops between forward and aft angles of trim is likely to have a KML (transverse metacentric height) that is less than the KGL (longitudinal metacentric height). This is because the vessel's stability characteristics in the transverse direction are insufficient to maintain an upright position, leading to the unstable trim behavior.
The other options are incorrect because they do not directly relate to the floping trim behavior described in the question. A greater KML, an off-center LCG, or an LCG greater than the LCB would not necessarily cause the semisubmersible to exhibit the described trim instability.
