The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the shift in VCG if 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials?
AI Explanation
The correct answer is C) 0.63 foot down.
When 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials, the vertical center of gravity (VCG) shifts down by 0.63 foot. This is because adding ballast to the lower part of the vessel increases the overall weight and lowers the VCG, resulting in a downward shift of 0.63 foot.
The other options are incorrect because they do not accurately reflect the change in VCG due to the specific ballasting scenario provided. The shift of 0.19 foot down (A), 0.44 foot down (B), and 1.19 feet down (D) are not the correct values for this specific case.
