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 KGL?
AI Explanation
The correct answer is C) 54.32 feet.
To calculate the new KGL (Keel to Gravity Line) after the non-liquid load is discharged, we need to consider the changes in the vessel's weight distribution. The discharge 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 will affect the vessel's KGL. The formula to calculate the new KGL is: KGL = (W1 * h1 + W2 * h2) / (W1 + W2), where W1 is the original weight, h1 is the original KGL, W2 is the weight of the discharged load, and h2 is the height of the discharged load above the keel. Plugging in the given values, the calculation results in the new KGL of 54.32 feet, which is the correct answer.
