Question 4804 Deck General
70% to passThe 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 KGT?
The correct answer is B) 53.65 feet. To calculate the new KGT (Vertical Center of Gravity of the Total Load), we need to use the formula: KGT = (KG x W + (discharge weight x discharge height)) / (W - discharge weight) Where: - KG is the original Vertical Center of Gravity of the Total Load - W is the original Total Weight - Discharge weight is the weight of the discharged non-liquid load - Discharge height is the vertical position of the discharged load Plugging in the given values, we get: KGT = (KG x W + (275.8 x 130)) / (W - 275.8) This formula correctly accounts for the change in weight and vertical position of the load, resulting in the new KGT of 53.65 feet, which is the correct answer. The other options are incorrect because they do not properly apply the formula to calculate the new KGT based on the given information.
