Question 4760 Deck General

The correct answer is B) It lowers the center of gravity. Jettisoning topside weight from a MODU (Mobile Offshore Drilling Unit) serves to lower the center of gravity of the vessel. This is important because a lower center of gravity increases the MODU's stability and ability to withstand heeling forces, such as wind and waves. Lowering the center of gravity reduces the vessel's tendency to capsize or become unstable, which is crucial for the safe operation of a MODU. The other options are incorrect because: A) Returning the MODU to an even keel is not the primary purpose of jettisoning topside weight. C) Reducing free surface effect is not the main reason for jettisoning topside weight. D) Raising the center of gravity would actually decrease the stability of the MODU, which is the opposite of the desired effect.
