Question 4955Deck General70% to pass
An elevated jack-up weighs 14,000 kips. Its TCG is located 1.0 foot to port of the centerline. What would be the new TCG for the jack-up if the drill floor, weighing 700 kips, is skidded 10 feet to starboard?
AI Explanation
The correct answer is D) 0.50 foot port.
The reasoning is as follows:
1) The initial TCG of the 14,000 kips jack-up is 1.0 foot to port of the centerline.
2) When the 700 kips drill floor is skidded 10 feet to starboard, the new overall center of gravity shifts towards the starboard side.
3) The new TCG will be 0.50 foot to the port side, as the shift in weight to starboard is not enough to overcome the initial 1.0 foot port offset.
4) The other options are incorrect as they do not accurately reflect the shift in the center of gravity caused by the drill floor movement.
