  • Tubular stabbing guide
    Patent number: 10619431
    Abstract: A tubular stabbing guide (10) used to assist in the location of a pin end connection of a tubular in a box end connection (14) of another tubular forming the upper end of a drill string held and supported from the drill floor (16) of a rig. The stabbing guide (10) has a mounting frame (22) for location on the drill floor (16) and funnel-forming members (32) mounted on the frame (22). In use, the funnel-forming members (32) are moved from a retracted location spaced from the box end connection (14) to an active location surrounding the box end connection (14), such that the funnel-forming members (32) form a funnel for guiding the pin end connection into the box end connection (14).

  • Safety interlock for control lines
    Patent number: 7717184
    Abstract: A protection tool is provided to protect a control line in a safe area while one or more slips of a spider are being closed. In another embodiment, a safety interlock system is provided to prevent the closing of the slips before the control line is pulled away from the tubular string. In yet another embodiment, a safety interlock system includes a safety interlock trigger adapted to be actuated by a protection tool. The safety interlock trigger is adapted to detect the physical presence of the protection tool, and thereafter send a signal to the interlock system to enable an operator or a control mechanism to safely close the slips.
