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?
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.
