Abstract
A pipeline reconditioning system and process is provided for reconditioning corroded or damaged pipelines. The reconditioning system includes a mobile topside unit storing and providing reservoirs and supplies of substances used in the pipeline reconditioning and the equipment for the reconditioning system, a management and towing units that are securely anchored in the pipeline at remote access points, and a towed delivery system array that includes a deployment sled that processes the substances and dispenses the reconditioning material, such as a composite epoxy resin with chopped glass or basalt filament fibers, between access points to the pipeline interior.
Claims20
A pipeline reconditioning system comprising:
- a pipeline delivery system comprising a control unit and a towable deployment sled configured to deliver and dispense a layer of a reconditioning material to an inner surface of a pipeline;
- a topside unit comprising one or more material reservoirs and a plurality of spools of pipe for delivering materials from the one or more material reservoirs to the pipeline delivery system;
- and
- a delivery system management unit configured to be securely anchored in the pipeline at a first pipeline access point and to communicate with the control unit of the pipeline delivery system.
A pipeline reconditioning method comprising:
- arranging within a pipeline, a pipeline delivery system comprising a control unit and a towable deployment sled configured to dispense a layer of a reconditioning material to an inner surface of the pipeline;
- providing one or more materials to the pipeline delivery system from one or more material reservoirs disposed in a topside unit comprising the one or more material reservoirs and a plurality of spools of pipe for delivering the one or materials from the one or more material reservoirs to the pipeline delivery system;
- and
- towing, by a delivery system management unit, the towable deployment sled through the pipeline while the towable deployment sled is dispensing the reconditioning material to the inner surface of the pipeline, the delivery system management unit comprising configured to be securely anchored in the pipeline at a first pipeline access point and to communicate with the control unit of the pipeline delivery system.
