An elevated jack-up weighs 14,000 kips. Its TCG is located 1.0 foot to starboard 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 port?

A 9.00 feet port

B 0.50 foot starboard

C 0.50 foot port

D 1.00 foot port

AI Explanation

The correct answer is B) 0.50 foot starboard. The reasoning is as follows: 1. The initial TCG of the jack-up is 1.0 foot to starboard of the centerline. 2. When the 700-kip drill floor is skidded 10 feet to port, it creates a moment that shifts the TCG towards port. 3. The new TCG is calculated by taking the original TCG and adjusting it based on the moment created by the drill floor skidding. 4. The calculation results in a new TCG that is 0.50 foot starboard of the centerline, making B the correct answer. The other options are incorrect because they do not accurately reflect the shift in TCG based on the given information.
