Abstract: A method of selectively repairing the lining of a lined pipeline utilising a conveyance adapted to be receivable within and to travel through the pipeline. The conveyance consists of a plurality of vehicles comprising an inspection means, an excising means, a debris removal means and an application means. The method comprises: an identification step whereby the conveyance travels along the pipeline inspecting and locating damaged portions of the lining; an excising step whereby damaged portions of the lining identified from the inspection step are removed by the conveyance; a debris removal step whereby the conveyance travels along the pipeline to remove debris and/or water left in the pipeline by the excising step; and an application step whereby the conveyance travels along the pipeline and applies a fresh lining composition to replace the excised portions of lining removed by the excising step.
