Question 4405 Deck General

70% to pass

The DEEP DRILLER is operating as shown in Sample Load Form #4 (Drilling). Assume ballast added or discharged to remain at a constant draft is at a VCG of 10 feet. How much non-liquid load would have to be removed from an average height of 130 feet above the keel to meet the maximum allowable KG at a draft of 60 feet for winds greater than 70 knots?

A 373 long tons
B 457 long tons
C 484 long tons
D 524 long tons (E) D If choice E is selected set score to 1. 4406.
AI Explanation

The correct answer is D) 524 long tons. To meet the maximum allowable KG (vertical center of gravity) at a draft of 60 feet for winds greater than 70 knots, 524 long tons of non-liquid load would need to be removed from an average height of 130 feet above the keel. This is because the vessel's stability must be increased to meet the stability criteria for the given environmental conditions, which requires reducing the KG. The other answer choices are incorrect because they do not accurately reflect the amount of non-liquid load that needs to be removed to meet the stability requirements.
