Question 4887Deck General70% to pass
The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of 6 and 7 drill water tanks are discharged, what would be the new VCG?
AI Explanation
The correct answer is D) 49.16 feet.
When the contents of the 6 and 7 drill water tanks are discharged, the overall weight of the vessel decreases, but the vertical center of gravity (VCG) increases. This is because the water tanks are located lower in the vessel's structure, so removing their contents raises the VCG. The calculation shows that the new VCG is 49.16 feet, which is the highest of the given options.
The other options are incorrect because they do not accurately reflect the change in VCG when the weight of the water tanks is removed from the lower part of the vessel.
