Question 3434 Deck General

70% to pass

The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Excessive motion makes it necessary to ballast down to survival draft. It is decided to check the stability at the intermediate draft of 32 feet. If the added ballast has an average VCG of 9.03 feet, and the sum of free surface moments is 56,244 foot-tons, what is the new margin on the maximum allowable KG?

A 6.23 feet
B 5.11 feet
C 4.86 feet
D 4.06 feet
AI Explanation

The correct answer is D) 4.06 feet. The key information given in the problem is the intermediate draft of 32 feet, the added ballast VCG of 9.03 feet, and the sum of free surface moments of 56,244 foot-tons. Using this information, along with the stability criteria for the maximum allowable KG, the new margin on the maximum allowable KG can be calculated to be 4.06 feet. The other answer choices are incorrect because they do not correctly apply the stability criteria and the given information to determine the new margin on the maximum allowable KG.
