Question 5013 Deck General

70% to pass

While loaded as shown in the COASTAL DRILLER sample load form 3 (drilling), all of the casing is discharged. What is the change in LCG?

A 1.98 feet forward
B 1.95 feet forward
C 0.02 foot forward
D 0.02 foot aft
AI Explanation

The correct answer is C) 0.02 foot forward. When the casing is discharged, the weight of the casing is removed from the vessel, resulting in a shift in the longitudinal center of gravity (LCG) forward by 0.02 feet. This is because the casing is located forward of the vessel's center of gravity, so removing its weight causes the LCG to move slightly forward. The other answer choices are incorrect because they do not accurately reflect the small magnitude of the LCG shift caused by the casing discharge. Options A and B overestimate the change, while option D is incorrect as the LCG shifts forward, not aft.
