The DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the metacentric height corrected for transverse free surface effects if 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials?
AI Explanation
The correct answer is D) 12.13 feet.
The metacentric height (GM) corrected for transverse free surface effects can be calculated using the formula: GM = KB + BM - KG - GML, where KB is the height of the center of buoyancy, BM is the transverse metacentric radius, KG is the height of the center of gravity, and GML is the free surface correction.
By adding 100.76 long tons of ballast to Ballast Tank #8S, the free surface effect is reduced, which increases the GM value. The provided information indicates that the DEEP DRILLER is loaded in the "Ballasting to Survival" condition, and the correct GM value is 12.13 feet.
The other answer choices are incorrect because they do not accurately reflect the GM value for the given loading condition and ballast addition.
