  • threaded connections known as tool joints
  • the process of threadably coupling adjacent pipe joints together is a time consuming process that requires a significant amount of pipe handling by the drilling rig's crew.
  • Drill collars - which are essentially thick-walled sections of drill pipe - are connected together to form the bottom hole assembly section of the drill string.
  • the drill collars are used to provide sufficient weight on the drill bit as the drill bit is rotated in the borehole to drill deeper.

  • drill pipe stands typically consist of two, three, or even four pipe joints threadably connected together.

Specifically, in the prior art systems, a first joint of drill pipe is lifted from the V-door ramp of the drilling rig and placed in a first off-line hole in a platform attached to the drilling rig that supports an off-line roughneck. A second joint of drill pipe is then lifted from the V-door ramp and placed in a second off-line hole in the off-line roughneck platform.
