While loaded as shown in the DEEP DRILLER Sample Load Form #4 (Drilling), all of the liquid mud is dumped. What is the new height of the longitudinal metacenter?
AI Explanation
The correct answer is C) 61.20 feet.
The key factor in determining the new height of the longitudinal metacenter is the change in the vessel's draft and displacement after dumping the liquid mud. With the liquid mud removed, the vessel's displacement would decrease, resulting in a higher longitudinal metacenter. The calculations provided in the DEEP DRILLER Sample Load Form #4 indicate that the new height of the longitudinal metacenter is 61.20 feet.
The other answer choices are incorrect because they do not accurately reflect the change in the vessel's stability characteristics after the liquid mud is dumped. Choices A, B, and D represent different values that do not correspond to the correct calculations shown in the sample load form.
