  • a tool joint seam (e.g., a location of the connection of the pin connector and the box connector) may be calculated using stored information about the tubular segments (e.g., the length of the respective tubular segments) and the current position of a tubular string including the tubular segments, as determined through one or more indirect measurements of the tubular segment positions (e.g., through measurements of a portion of drawworks supporting the tubular string).
  • activation of one or more slips to secure one of the tubular segments may be controlled based upon the calculated tool joint seam to allow for attachment or detachment of the tubular segments.

  • the spinner 60 and the makeup/breakout jaws 58 may provide rotational torque.
  • the spinner 60 may engage the first tubular segment 44 and provide a relatively high-speed, low-torque rotation to the first tubular segment 44 to connect the first segment 44 to the second segment 46.
