Question 4803 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 TCG?
A
-0.26 foot
B
-0.46 foot
C
0.46 foot
D
0.61 foot
AI Explanation
The correct answer is C) 0.46 foot. The new Transverse Center of Gravity (TCG) can be calculated by taking the moment created by the discharged load and dividing it by the vessel's displacement. The moment is calculated by multiplying the weight of the discharged load (275.8 long tons) by its distance from the centerline (30 feet to port). This gives a moment of 8,274 foot-long tons. Dividing this moment by the vessel's displacement results in a new TCG of 0.46 foot to port. The other answer choices are incorrect because they do not properly account for the moment created by the discharged load and its effect on the vessel's TCG.
