What is the term for the part of the drilling rig that rises above the substructure and houses the crown block and draw works?

• A. Derrick
• B. Drill Floor
• C. Crown Block
• D. Drawworks

Answer: (A)

The main idea is the vertical structure on a drilling rig that supports the hoisting system. That tall tower rises above the substructure and provides the height needed to handle long sections of pipe, with the crown block at its top and the hoisting gear connected to it. This entire structure is known as the derrick. The drill floor is where the crew works at the base, the crown block is the set of pulleys mounted at the top of the tower, and the drawworks is the hoisting winch system that reels the drill line. While those components are part of the hoisting system, they’re not the overall structure itself, which is why derrick is the correct term.
