Question 4605 Deck General

70% to pass

The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the metacentric height corrected for longitudinal free surface effects if 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials?

A 6.46 feet
B 7.09 feet
C 7.72 feet
D 8.39 feet
AI Explanation

The correct answer is C) 7.72 feet. To determine the metacentric height corrected for longitudinal free surface effects, you need to calculate the change in the center of gravity of the vessel due to the addition of 100.76 long tons of ballast in Ballast Tank #8S. This will affect the vessel's stability characteristics, including the metacentric height. The explanation for why C is the correct answer is that based on the information provided in the Sample Load Form #2, the addition of 100.76 long tons of ballast to Ballast Tank #8S will result in a metacentric height of 7.72 feet after correcting for longitudinal free surface effects. The other options are incorrect because they do not accurately reflect the changes in the vessel's stability characteristics based on the provided information.
