What is the maximum permitted hook load for the COASTAL DRILLER when 450 kips are in the setback and no other loads are on the cantilever?

Correct Answer: Option B — 529 kips

Consulting the COASTAL DRILLER cantilever and setback load limitation diagrams shows that with 450 kips in the setback, structural and stability limits allow a maximum hook load of 529 kips without exceeding allowable combined bending moments.
