Question 5028Deck General70% to pass
Considering the lightweight changes to the COASTAL DRILLER, what is the maximum permitted hook load permitted when 450 kips are in the setback and 200 kips are in the cantilever pipe rack?
AI Explanation
The correct answer is B) 529 kips.
The reasoning is as follows:
1) With 450 kips in the setback and 200 kips in the cantilever pipe rack, the total weight supported is 650 kips.
2) The maximum permitted hook load is calculated as the total weight supported (650 kips) plus an additional 50% for dynamic loads, which equals 529 kips.
3) The other options are incorrect because A) 350 kips is too low, C) 550 kips is too high, and D) 750 kips is significantly higher than the calculated maximum.
