Question 4909Deck 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 is the new height of the center of gravity corrected for transverse free surface effects?
AI Explanation
The correct answer is C) 50.82 feet.
To arrive at this answer, we need to consider the effects of discharging the contents of the 6 and 7 drill water tanks on the center of gravity of the vessel. Discharging the water will decrease the weight of the vessel and shift the center of gravity upward, resulting in a higher center of gravity.
The calculation to determine the new height of the center of gravity, corrected for transverse free surface effects, takes into account the change in weight and the shift in the center of gravity. The provided information and calculation indicate that the correct answer is 50.82 feet.
The other options are incorrect because they do not accurately reflect the new height of the center of gravity after the water discharge.
