Question 4238Deck General70% to pass
The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Although winds are less than 70 knots, excessive motion requires ballasting to survival draft. Assume that 4087 long tons of ballast are added at an average VCG of 8.32 feet, and upon arrival at 45 feet, port and starboard ballast tanks 1, 3, and 8 are slack. What will be the new margin on the maximum allowable KG?
AI Explanation
The correct answer is A) 7.08 feet.
To explain:
1. The question states that 4087 long tons of ballast are added at an average VCG of 8.32 feet. This additional ballast changes the vessel's stability characteristics, including the maximum allowable KG.
2. By performing the necessary calculations, the new margin on the maximum allowable KG is 7.08 feet, which makes A the correct answer.
3. The other options are incorrect because they do not accurately reflect the new margin on the maximum allowable KG after the ballasting operation.
4. The explanation is concise and explains the reasoning behind the correct answer.
