English term or phrase: derrick
Definition from Petex:
a large load-bearing structure, usually of bolted construction. In drilling, the standard derrick has four legs standing at the corners of the substructure and reaching to the crown block. The substructure is an assembly of heavy beams used to elevate the derrick and provide space to install blowout preventers, casingheads, and so forth.

Example sentence(s):
  • A worn bit can be detected by the noise on the derrick floor that the rotating drill pipe makes and by a decrease in rate of drill penetration. Foster Learning Inc.
  • The downward force on the drill bit is the result of the weight of the overhead drill stem (steel pipe, pipe joints called collars) and drilling equipment on the derrick all of which can amount to thousands of pounds. Tidal Petroleum
  • The worker in the photo below is known as a derrick man. He works up at the top of the oil rig and stacks the "stands" or combined joints of pipe back against the derrick. energyindustryphotos.com
