Question 4862Deck 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 uncorrected KG?
AI Explanation
The correct answer is B) 52.20 feet.
This is the correct answer because when the liquid mud is dumped, the total weight of the vessel decreases, resulting in a higher vertical center of gravity (KG). The Sample Load Form #4 provides the necessary information to calculate the new uncorrected KG after the liquid mud is dumped.
The other options are incorrect because they do not accurately reflect the change in KG caused by the reduction in weight from the dumped liquid mud. Option A (52.09 feet) is too low, while options C (53.23 feet) and D (55.36 feet) are too high.
