Question 4820Deck General70% to pass
A semisubmersible, while floating level, displaces 25,000 long tons. LCG is 2 feet forward of amidships. Bulk, weighing 300 long tons, is placed in P-tanks located 50 feet aft of amidships. What is the new LCG?
AI Explanation
The correct answer is B) 1.38 feet forward of amidships.
To explain the reasoning:
The location of the new LCG (Longitudinal Center of Gravity) can be calculated using the formula: LCG = (25,000 x 2 - 300 x 50) / (25,000 - 300) = 1.38 feet forward of amidships.
The other options are incorrect because they do not align with the calculated result. Option A is too large, Option C is too small, and Option D is also too small.
