Question 4795 Deck General

70% to pass

The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). What is the new transverse free surface correction (FSCT) if the entire contents of Salt Water Ballast Tanks 1P and 1S are discharged?

A 0.46 foot
B 0.71 foot
C 1.08 feet
D 1.44 feet
AI Explanation

The correct answer is A) 0.46 foot. When the contents of the Salt Water Ballast Tanks 1P and 1S are discharged, the free surface effect (FSE) is reduced, which in turn reduces the transverse free surface correction (FSCT). The reduction in FSCT is calculated based on the change in the free surface moment (FSM) of the tanks. Since the entire contents of the tanks are discharged, the new FSM becomes zero, and the new FSCT is calculated to be 0.46 foot. The other options are incorrect because they do not accurately reflect the change in FSCT due to the discharge of the ballast tanks.
