Question 4819 Deck General

70% to pass

A semisubmersible, while floating level, displaces 18,000 long tons. Bulk, weighing 400 long tons, is placed in P-tanks located 80 feet to starboard of the centerline. What is the new TCG?

A 0.02 foot starboard of centerline
B 0.32 foot starboard of centerline
C 1.74 feet starboard of centerline
D 1.78 feet starboard of centerline
AI Explanation

The correct answer is C) 1.74 feet starboard of centerline. To calculate the new TCG (transverse center of gravity), we need to use the formula: TCG = (Bulk Weight x Bulk Offset) / Total Displacement. The bulk weighs 400 long tons and is placed 80 feet to starboard of the centerline. The original displacement is 18,000 long tons. Plugging these values into the formula, we get: TCG = (400 x 80) / 18,000 = 1.74 feet starboard of centerline. The other options are incorrect because they do not properly account for the weight and location of the bulk in relation to the original displacement.
