The DEEP DRILLER is loaded as shown in the Sample Load Form #5 (Survival), when an unexpected, slowly increasing port list and bow down trim occurs. A leak in C1P is found. By deballasting from ballast tanks 2P and 3P, the inclination slowly decreases. The increase in the longitudinal free surface correction is _______________.
AI Explanation
The correct answer is D) 0.49 foot.
The increase in the longitudinal free surface correction is directly related to the change in the free surface moment of the ballast tanks as water is pumped out. By deballasting from ballast tanks 2P and 3P, the free surface moment decreases, which leads to a decrease in the longitudinal free surface correction. The formula for longitudinal free surface correction is directly proportional to the free surface moment, so a decrease in the free surface moment results in a decrease in the longitudinal free surface correction.
The other options are incorrect because they do not accurately reflect the decrease in the longitudinal free surface correction due to the deballasting of the port ballast tanks.
