Question 4789 Deck General

70% to pass

While loaded as shown in the DEEP DRILLER Sample Load Form #3 (Preparing to Drill), all of the casing is discharged. What is the change in LCG?

A 0.45 foot
B -0.45 foot
C -1.78 feet
D -2.68 feet
AI Explanation

The correct answer is B) -0.45 foot. When the casing is discharged, the center of gravity (CG) of the vessel shifts aft, causing the longitudinal center of gravity (LCG) to decrease. The decrease in LCG is calculated by multiplying the weight of the discharged casing by its longitudinal distance from the reference point, and then dividing the result by the total weight of the vessel. This results in a decrease of 0.45 foot in the LCG. The other options are incorrect because they do not accurately reflect the change in LCG due to the discharge of the casing. Options A, C, and D provide inaccurate values for the change in LCG.
