  • Pipeline recovery tool
    Patent number: 6402428
    Abstract: A pipeline recovery tool is made from steel plates welded together instead of forging and machining. The rigged-up tool is lowered over the pipeline and engaged with the pipeline such that a fixed claw engages the collar on the pipeline. An ROV is used to cause a movable dog on the tool to engage the collar and then lock the fixed claw in position. Rigging on the fixed claw side of the tool is released. The pipeline is then lifted to the surface by a lift arm on the first end of the tool.
