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 __________.
Official USCG Answer & Rule Citation
Correct Answer: Option D — 0.49 foot
Longitudinal free surface correction changes derive from the shifting moments of inertia within modified tank configurations. Mathematical evaluation using sample load form data confirms the resulting longitudinal free surface correction increase equals 0.49 foot.
