A semisubmersible, with a TCG of 0.5 foot to port, displaces 20,000 long tons. Bulk, weighing 400 long tons, is loaded in P-tanks located 50 feet starboard to the centerline. What is the new TCG?

A 0.49 foot starboard of centerline
B 0.51 foot starboard of centerline
C 0.99 foot starboard of centerline
D 1.49 feet starboard of centerline
AI Explanation

The correct answer is A) 0.49 foot starboard of centerline. To calculate the new TCG, we need to use the formula: (Current TCG * Current Displacement + Shift in CG * Weight of Shift) / New Displacement. Given: - Current TCG: 0.5 foot to port - Current Displacement: 20,000 long tons - Bulk Loaded: 400 long tons - Bulk Location: 50 feet starboard to the centerline Plugging in the values, we get: New TCG = ((-0.5) * 20,000 + 50 * 400) / 20,400 = -10,000 + 20,000 / 20,400 = 0.49 foot starboard of centerline The other options are incorrect because they do not match the calculated value of 0.49 foot starboard of centerline.
