Abstract:
An operational system and method and improved apparatus for positioning and stabbing well tubulars wherein: the grasping members of the apparatus can be folded and unfolded; the boom assembly can be pivoted to a downward clearance position; a plurality of stabbing apparatuses can be placed and used in a stacked position in the derrick; the grasping members can opened at an angle with respect the boom; the grasping members can be mounted on either lateral side of the boom; a sensor monitors the relative position of the rig top drive with respect to the stabbing apparatus; the grasping members and/or the boom will automatically pivot to a breakaway position if impacted; and/or the system is programmed and configured to prevent the accidental performance of critical operations out of sequence.
