Methods for repairing a defect in a pipeline. In some embodiments, the method includes filling the defect with a paste such that an outer surface of the defect is substantially flush with an adjacent outer surface of the pipeline, curing the paste, manually wrapping a reinforcing material around the pipeline over the defect region for a plurality of turns, coupling the reinforcing material to the pipeline, wherein a pressure load applied to an inner surface of the pipeline is transferred through the pipeline and the paste to the reinforcing material so as to increase a safe operating pressure of the pipeline, and electrically coupling the reinforcing material and the pipeline, whereby an electrical potential in the pipeline is transmitted to the reinforcing material. |
