Pipe Handling Tools


  • A Pipeline Retrieval Tool provides the connection between the pipeline and the recovery cable required to handle or manoeuvre the pipeline end. The Pipeline Retrieval Tool engages in the pipeline bore to provide a secure but controllable facility for the connection of the retrieval cable.

    Tapered locks featuring the Diamondlock™ tooth profile operate on a wedge principle, improving the connection efficiency as the load increases.

    The laying of subsea pipelines involves the placement of large diameter tubulars in an environment where extreme forces or motions may result in buckling and flooding the pipeline. In this event, the damaged pipe section must be removed and a repair process implemented. The replacement pipe may be tied-in using hyperbaric welding facilities, or the pipeline end may be recovered to the pipe lay vessel for surface repairs.

    Once set, this fail-safe mode of operation enables the mechanical connection with the pipeline to remain secure independent of the tool hydraulic activation system. A seal and vent system within the Pipeline Retrieval Tool assembly enables the pipe to be de-watered prior to the lifting operation.

    The acquisition and development of Tecnomarine technologies, has enabled STATS to develop a comprehensive range of Pipeline Retrieval Tools. The combined track record in this highly specialised engineering and manufacturing sector includes tools in a range of 16 to 44 diameter.
