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?
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.
