Question 5012Deck General70% to pass
Because there is a possibility of fuel oil being discharged overboard from a full fuel oil tank, it is decided to transfer 25 kips from tank 14 to tank 20. See COASTAL DRILLER Sample Load Form Number 1 (Rig Move). What would be the change in longitudinal moments with this transfer?
AI Explanation
The correct answer is A) 565 ft-kips.
When transferring 25 kips of fuel oil from tank 14 to tank 20, the change in longitudinal moments is calculated by multiplying the weight transferred (25 kips) by the distance between the two tanks' longitudinal centers of gravity. Based on the information provided in the COASTAL DRILLER Sample Load Form Number 1, the distance between the longitudinal centers of tanks 14 and 20 is 22.6 feet. Multiplying the weight transferred (25 kips) by the distance (22.6 feet) results in a change in longitudinal moments of 565 ft-kips.
The other answer choices are incorrect because they do not accurately reflect the change in longitudinal moments based on the given information and calculation.
