The DEEP DRILLER, at 60.0 feet draft in sea water, has VM = 974,441 foot-long tons, LM = 40,301 foot-long tons, TM = 3 foot-long tons, FSML = 30,572 foot-long tons, and FSMT = 18,732 foot-long tons. What is the longitudinal free surface correction to KG?

A 0.00 feet

B 1.03 feet

C 1.69 feet

D 2.22 feet

AI Explanation

The correct answer is C) 1.69 feet. To calculate the longitudinal free surface correction to KG, we can use the formula: Longitudinal free surface correction to KG = (FSML + FSMT) / VM Plugging in the given values: Longitudinal free surface correction to KG = (30,572 + 18,732) / 974,441 = 49,304 / 974,441 = 1.69 feet The other options are incorrect because: A) 0.00 feet is too low and does not account for the given free surface moments. B) 1.03 feet is too low and does not match the correct calculation. D) 2.22 feet is too high and does not match the correct calculation.
