Question 4707 Deck General

The correct answer is A) midway between the forward and aft draft marks. The mean draft of a mobile offshore drilling unit (MODU) is the average of the forward and aft draft marks, which indicates the draft at the midpoint of the vessel. This is the standard method for determining the mean draft, as it provides a representative measurement of the overall draft of the MODU. The other options are incorrect because: B) the center of flotation is not necessarily the same as the mean draft, C) the load line is a separate measurement, and D) the center of buoyancy is a different characteristic than the mean draft.
