Question 4408Deck General70% to pass
The DEEP DRILLER, at 60.0 feet draft in sea water, has VM = 974,441 foot-long tons, LM = 3 foot-long tons, FSML = 30,572 foot-long tons, and FSMT = 18,732 foot-long tons. What is the transverse free surface correction to KG?
AI Explanation
The correct answer is B) 1.03 feet.
The transverse free surface correction to KG is calculated using the formula: Transverse Free Surface Correction = (FSMT / VM) * Metacentric Height (GM).
In this case, with the given values of FSMT (18,732 foot-long tons) and VM (974,441 foot-long tons), the transverse free surface correction comes out to 1.03 feet.
The other options are incorrect because they do not accurately reflect the calculation using the provided information. Option A is incorrect as it does not account for the free surface effect. Options C and D are also incorrect as they do not match the calculated value of 1.03 feet.
