For a MODU with list, a decrease in GM will cause the angle of inclination to _______________.
AI Explanation
The correct answer is B) increase.
A decrease in GM (metacentric height) for a MODU (Mobile Offshore Drilling Unit) will cause the angle of inclination to increase. This is because a lower GM reduces the vessel's stability, allowing the MODU to heel over to a greater angle when subjected to an external force or moment.
The other options are incorrect because:
A) A decrease in GM would not cause the angle of inclination to decrease, as that would be contrary to the loss of stability.
C) The angle of inclination cannot remain constant when the GM decreases, as the vessel would become less stable.
D) The angle of inclination would not stabilize at an angle of loll, as that would require the GM to become negative, which is an unsafe condition.
