For a MODU with longitudinal inclination, an increase in GML causes _______________.

AI Explanation
The correct answer is B) trim to decrease. When a MODU (Mobile Offshore Drilling Unit) experiences longitudinal inclination, an increase in the metacentric height (GML) will cause the trim to decrease. This is because an increase in GML results in greater stability, which in turn reduces the vessel's tendency to trim or list. By decreasing the trim, the MODU will become more stable and better able to maintain an upright position. The other options are incorrect because: A) An increase in GML would not cause the trim to increase, as that would make the vessel less stable. C) Stabilizing at an angle of loll is not the correct response to an increase in GML. D) Stabilizing at an angle of loll is also not the correct response to an increase in GML.
