  • Method for coupling connectors using an anti-rotation device
    Patent number: 7146704
    Abstract: The present invention is generally directed to an anti-rotation device for mating connectors, and methods of using same. In one illustrative embodiment, the method comprises coupling a first connector to a second connector, removing at least a portion of the second connector after the first and second connectors are coupled together to thereby define a recess in the second connector, and coupling an anti-rotation member to at least one of the first and second connectors, wherein the anti-rotation member engages at least a portion of the first connector and is adapted to engage at least a portion of the recess in the second connector.

  • Large diameter flush-joint pipe handling system
    Patent number: 7044216
    Abstract: An elevator for assembling a plurality of a large diameter pipe joints into a pipe string with a drilling rig is disclosed. The first one of a number of large diameter pipe joints is adapted to threadingly engage another large diameter pipe joint. The elevator is detachably securable to the upper end of the first joint, and is adapted to both lift and position the first joint while it is stabbed and tightened onto the string. The elevator is further adapted to co-operatively engage the rotary table of the drilling rig to rotatably tighten the second joint to the first joint as the second joint is added to the string.
