Abstract
Flexible liners for relining fluid transport pipelines contain at least one integral conduit which has no fluid communication with either the interior of the lining of the relined pipeline, or with the inside wall of the pipeline itself. The integral but substantially fluid-isolated conduit may serve to carry telecommuncations or other cables, thus providing an economical means of introducing telecommuncations through existing pipeline infrastructure without necessitating abandonment of the fluid transport capabilities of the pipeline.
