Question 5004 Deck General

The correct answer is B) 1 foot 2 inches by the stern. The explanation is as follows: 1. The jack-up is initially trimmed 6 inches by the bow. To change the trim by 1 inch, a moment of 1200 foot-kips is required. Transferring 200 kips of drill water from a tank with an LCG of 20 feet to a tank with an LCG of 140 feet results in a moment of 24,000 foot-kips (200 kips x 120 feet). This moment will change the trim by 20 inches, resulting in a final trim of 1 foot 2 inches by the stern. 2. This calculation is based on the principles of ship stability and trim, which are essential for ensuring the safe operation of vessels, including those operated by the US Coast Guard. 3. The other options are incorrect because they do not accurately reflect the final trim of the jack-up based on the given information.
