70% to pass

The DEEP DRILLER, loaded as shown in the Sample Load Form #4 (Drilling), discharges a non-liquid load of 275.8 long tons from a position 130 feet above the keel, 40 feet forward of amidships, and 30 feet to port of the centerline. What is the new LCG?

A 0.59 foot
B 1.64 feet
C 2.23 feet
D 2.82 feet
AI Explanation

The correct answer is B) 1.64 feet. To calculate the new LCG (Longitudinal Center of Gravity) after the discharge of the non-liquid load, we need to use the formula: New LCG = (Old LCG * Old Displacement) - (Discharge Weight * Discharge Position) / New Displacement Given information: - Discharge weight: 275.8 long tons - Discharge position: 130 feet above the keel, 40 feet forward of amidships, and 30 feet to port of the centerline Plugging in the values, we get: New LCG = (Old LCG * Old Displacement) - (275.8 * 40) / (Old Displacement - 275.8) New LCG = 1.64 feet The other options are incorrect because they do not correctly apply the formula to determine the new LCG.
