A semisubmersible with displacement of 19,700 long tons and KG of 50.96 feet loads 300 long tons of barite into P-tanks located 120 feet above the keel. What is the change in KG?
AI Explanation
The correct answer is C) 1.04 feet upward.
To calculate the change in KG, we need to use the formula: New KG = (Original KG * Original Displacement + Change in Height * Additional Load) / (Original Displacement + Additional Load).
Given:
- Original Displacement: 19,700 long tons
- Original KG: 50.96 feet
- Additional Load: 300 long tons
- Change in Height: 120 feet
Plugging these values into the formula:
New KG = (50.96 * 19,700 + 120 * 300) / (19,700 + 300)
= 52.00 feet
The change in KG is therefore 52.00 feet - 50.96 feet = 1.04 feet upward, which matches answer choice C.
The other answer choices are incorrect because they do not match the calculated value of 1.04 feet upward.
