Question 4400 Deck General
70% to passThe DEEP DRILLER is drilling at 60 feet draft at a corrected KG of 54.0 feet. 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?
The correct answer is D) 302 long tons. The reasoning is as follows: 1. The DEEP DRILLER has a draft of 60 feet and a corrected KG (vertical center of gravity) of 54.0 feet. 2. To meet the maximum allowable KG at a draft of 60 feet for winds greater than 70 knots, the non-liquid load would need to be removed from an average height of 130 feet above the keel. 3. The amount of non-liquid load that needs to be removed is 302 long tons, as this would reduce the KG to the maximum allowable level. 4. The other options are incorrect because they do not accurately reflect the necessary reduction in non-liquid load to meet the maximum allowable KG for the given conditions.
