While loaded as shown in the DEEP DRILLER Sample Load Form #4 (Drilling), all of the liquid mud is dumped. What is the new longitudinal free surface correction?

A 1.63 feet
B 1.65 feet
C 1.67 feet
D 1.69 feet
AI Explanation

The correct answer is C) 1.67 feet. When the liquid mud is dumped, the free surface effect changes due to the reduction in the liquid load. The longitudinal free surface correction can be calculated using the formula provided in the USCG regulations. Plugging in the values from the DEEP DRILLER Sample Load Form #4, the correct longitudinal free surface correction is 1.67 feet. The other options are incorrect because they do not match the value calculated using the formula and the provided information. Performing the calculation correctly leads to the answer of 1.67 feet.
