The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). What is the new height of the center of gravity corrected for transverse free surface effects if the entire contents of Salt Water Ballast Tanks 1P and 1S are discharged?

A 65.95 feet
B 66.85 feet
C 67.66 feet
D 68.59 feet
AI Explanation

The correct answer is D) 68.59 feet. The height of the center of gravity (VCG) is corrected for the transverse free surface effects when the contents of the salt water ballast tanks are discharged. This causes the VCG to shift higher, increasing the overall height of the center of gravity. The calculation to determine the new VCG considers the change in weight and moment due to the discharged ballast, which results in the VCG increasing to 68.59 feet. The other options are incorrect because they do not accurately reflect the change in VCG after the ballast tanks are discharged. The correct answer of 68.59 feet is the proper calculation considering the transverse free surface effects.
