The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). What is the new metacentric height corrected for longitudinal free surface effects if the entire contents of salt water ballast 1anks 1P and 1S are discharged? (Use KML = 348.58

A A
B B
C C
D D
AI Explanation

The correct answer is C. To calculate the new metacentric height (GM) corrected for longitudinal free surface effects, we need to use the formula: GM = KML - KG - GG' Where: - KML = 348.58 (given) - KG = the vertical center of gravity - GG' = the longitudinal free surface correction Since the entire contents of salt water ballast tanks 1P and 1S are discharged, the longitudinal free surface correction (GG') will be reduced, resulting in an increase in the metacentric height (GM). The other answer choices do not provide the correct GM value after the ballast discharge, as they do not properly account for the change in the longitudinal free surface correction.
