Abstract: A fall arrest safety system for overhead rotating tools includes a tether ring assembly having an inner ring and an outer ring. The inner ring clamps onto the rotating tubular and the outer ring is tethered to the top drive unit. In the event of a disconnect, the tethered assembly holds the load.

Abstract: A tubular lift ring for positioning a tubular for making up a string. The ring includes internal threads that match a portion of the external threads on the end of the tubular. The ring further includes an upset that contacts the setting plate of an elevator for clamping about the tubular and lifting it into place above the borehole.

Abstract: A device and method for installing a pipe into a rotating control device (RCD) head and for removing a pipe out from a RCD head are described. The device includes a body section for receiving and securing a RCD head placed thereon; and a scoping section configured to secure a first end of the pipe, and to push the first end of the pipe into a bore of the RCD head or to pull the first end of the pipe out from bore of the RCD head. The body section is configured to be substantially stationary when the scoping section pushes the first end of the pipe into the bore of the RCD head, or when the scoping section pulls the first end of the pipe out from the bore of the RCD head.

Abstract: A portable bucking frame for making and breaking tubular connections includes a base, a pair of back-up jaws movably mounted to the base for receiving a pipe and an adapter plate mounted on the front end of the base. The adapter plate is configured to receive one of a plurality of power tongs for making or breaking pipe connections.

Abstract: A saw for cutting a surface with a rotatable blade. The saw includes a rotary motor having a rotatable rotor and a rotatable output shaft. A rotatable blade mounting member is operatively coupled to the output shaft of the rotary motor such that rotation of the output shaft causes rotation of the blade mounting member. A steering assembly having one or more wheels provides steering control of the saw.
