If a severe storm threatens the COASTAL DRILLER while elevated, the setback in the derrick should be lowered and placed in the pipe rack. Its weight should be accounted for as _______________.
AI Explanation
The correct answer is C) variable loads.
When a severe storm threatens the COASTAL DRILLER while elevated, the setback in the derrick should be lowered and placed in the pipe rack. Its weight should be accounted for as variable loads, as the weight of the setback can fluctuate depending on the operating conditions and environmental factors.
The other options are incorrect because fixed weight refers to the constant weight of the structure, drilling loads are the loads associated with the drilling operation, and environmental loads are the loads imposed by external factors like wind, waves, and currents.
