Question 4497Deck General70% to pass
The COASTAL DRILLER is elevated while preparing for the passage of a severe storm. With ideal loading, the static loading on each of the three legs would be 4,715 kips. However, the LCG is 121 feet AFO and TCG is 0.5 foot to starboard of the centerline. By how many kips does the starboard leg reaction exceed the ideal loading?
AI Explanation
The correct answer is C) 149 kips.
The explanation is as follows:
1. Confirm the correct answer: C) 149 kips is the correct answer.
2. Explanation of the reasoning: With the given information of the LCG being 121 feet AFO and the TCG being 0.5 foot to starboard, the static loading on the starboard leg will be greater than the ideal loading of 4,715 kips. This is due to the offset of the LCG, which creates a moment that increases the loading on the starboard leg.
3. Explanation of why the other options are incorrect: Option A) 00 kips is incorrect because the starboard leg reaction will exceed the ideal loading. Option B) 32 kips is incorrect because the actual increase in the starboard leg reaction is higher. Option D) 181 kips is incorrect because the increase in the starboard leg reaction is less than this value.
