Question 5029 Deck General

The correct answer is A) drill string. The hook load on a coastal driller includes the weight of the drill string, which is the assembly of drill pipes, drill collars, and the drill bit that extends down into the well. The hook load represents the total weight being supported by the rig's hoisting equipment, which includes the weight of the drill string as the primary component. The other answer choices are incorrect because they do not represent the full weight being supported by the hook. Conductor tension, rotary load, and setback load are all components that contribute to the overall hook load, but they do not encompass the entire weight being lifted.
