Question 4638 Deck General
70% to passThe DEEP DRILLER is loaded as shown in the Sample Load Form #2 (Ballasting to Survival). What is the shift in LCG if 100.76 long tons of ballast are added to Ballast Tank #8S to replace the discharge of all bulk materials?
A
0.06 foot aft
B
0.14 foot aft
C
0.27 foot aft
D
0.40 foot aft
AI Explanation
The correct answer is A) 0.06 foot aft. When 100.76 long tons of ballast are added to Ballast Tank #8S, the longitudinal center of gravity (LCG) of the DEEP DRILLER shifts aft by 0.06 foot. This is because the addition of ballast in the aft tank moves the overall center of gravity of the vessel slightly aft. The other answer choices are incorrect because they do not accurately reflect the small shift in LCG caused by the addition of 100.76 long tons of ballast in the specific tank. The shift in LCG is relatively minor compared to the overall size and weight of the vessel.
