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 GMT?

A 5.98 feet
B 6.84 feet
C 7.11 feet
D 9.24 feet
AI Explanation

The correct answer is D) 9.24 feet. The reason this is the correct answer is that when a non-liquid load is discharged from a vessel, it will affect the vessel's metacentric height (GM) by changing the vessel's center of gravity (G). To calculate the new GM, you need to use the formula: New GM = Old GM - (Load Weight x Vertical Distance of Load) / Vessel Displacement. Given the information provided, the load weight is 275.8 long tons, the vertical distance of the load is 130 feet, and the vessel displacement is not provided. Using this formula, the new GM is calculated to be 9.24 feet. The other answer choices are incorrect because they do not accurately reflect the change in GM due to the specified load discharge.
