Abstract
A multi-layered liner for lining a pipeline which has an external jacket, an interior liner, a woven intermediate layer between the external jacket and the interior liner. At least one optical fiber is in the woven intermediate liner for purposes of monitoring stress or for communication, and a capacitance leak detection circuit is also in the multi-layered liner for the purpose of detecting leaks in the multi-layered liner. Also included is the method of monitoring a pipeline for stress or leakage by use of a stress detector connected to an optic fiber in a multi-layered liner installed in the pipeline and a leak detector connected to a capacitance circuit in a multi-layered liner installed in a pipeline.
