Abstract: A pipe ram blowout preventer may be used for sealing about an object positioned in a vertical bore extending through the blowout preventer. The blowout preventer includes a pipe ram assembly movable towards the tubular, the pipe ram assembly including a packer assembly comprising an elastomeric body for sealing against the object. The packer assembly includes an upper plate position above the elastomeric body which includes a tab extending from the upper plate. The tab resists extrusion of the elastomeric body in high temperature environments by containing the elastomeric material and forming a metal-to-metal seal about the object positioned in the blowout preventer vertical bore.

Abstract: A pipe ram blowout preventer (“BOP”) may be used for sealing about an object positioned in a vertical bore extending through the BOP. The BOP includes a pipe ram assembly movable towards the tubular, the pipe ram assembly including a packer assembly comprising an elastomeric body for sealing against the object. The packer assembly includes a packer insert within the elastomeric body, the packer insert comprising a generally interlaced structure, such as a wire mesh. The packer insert reduces deleterious effects of using a pipe ram assembly in high temperature environments by resisting crumbling of the elastomeric material when it becomes brittle.

Abstract: A blowout preventer (“BOP”) includes a housing comprising a vertical bore extending through the housing, and a pair of opposing shear rams configured to move into the vertical bore. The shear rams comprise an engagement feature configured to engage with a corresponding engagement feature and urge the shear rams into axially towards each other with respect to an axis of the vertical bore when the shear rams are located in the vertical bore.

Abstract: A door breach training system comprising a first restraint assembly connecting a door to a frame. The door is attached to a lock jamb of the frame with a first restraint assembly that exposes a shear joint to impact from a projectile, such as shotgun round. Another embodiment further comprises attachment of the door to the hinge jamb with at least one second restraint assembly that functionally simulates a typical door hinge and exposes a shear joint to impact from a ballistic round. The preferred embodiment includes replaceable lock panels and hinge panels that are designed to break in a known manner in order to replicate those same failure modes for both door locks and door hinges in typical residential and commercial construction environments.

Abstract: A packable battering ram quickly disassembled for transport by two or more persons. In the preferred embodiment, the invention has first and second body members that are symmetrical, but otherwise identically shaped and sized. When assembled, the first and second body members form a lower surface that has a concave portion that approximates the natural curvature of the back of an adult male. The packable battering may be disassembled to distribute the weight between multiple people, yet quickly assembled for use upon arrival at a emergency response location.

Abstract: A method and apparatus for positioning and supporting the work platform of a mobile workover rig is disclosed. The work platform of the preferred embodiment of the present invention utilizes a unique support structure and automated positioning system for positioning the work platform at the desired height above the wellhead equipment. The preferred embodiment of the present invention utilizes a specialized automated “pinning” system that secures the work platform at the desired height. Additionally, the present invention utilizes one or more support cylinders to position and support the work platform in the horizontal position over the wellhead equipment. The automated positioning and pinning system of the present invention is a unique system that significantly reduces the time required to position the work platform of a mobile workover rig in the operating position, as well as significantly reduces the risk of injury to rig personnel assisting in the positioning operations.

Abstract: Various embodiments of a media drive containment apparatus and methods are provided. In one representative embodiment a media drive containment apparatus includes a drivecage which supports at least one media drive. The drivecage is moveable along an axis from an operating position to a release position and the movement of the drivecage to the release position unlocks the media drive from the drivecage.
