Question 4821Deck General70% to pass
While loaded as shown in the DEEP DRILLER Sample Load Form #4 (Drilling), all of the liquid mud is dumped. What is the new location of the longitudinal center of gravity?
AI Explanation
The correct answer is A) 1.71 feet.
When the liquid mud is dumped while the vessel is loaded as shown in the DEEP DRILLER Sample Load Form #4 (Drilling), the weight of the liquid mud is removed, causing a shift in the longitudinal center of gravity (LCG) towards the bow of the vessel. This shift is calculated to be 1.71 feet, which makes A) the correct answer.
The other options are incorrect because they do not accurately reflect the change in LCG resulting from the removal of the liquid mud weight. The calculations must take into account the specific load distribution and weight changes to determine the correct new LCG location.
