A submerged marine pipeline (201) is electrically insulated from sea water and is heated by alternating current that flows through the pipeline, where the AC power supply (212) is grounded to ambient sea water (206). The insulating material is cast between an assembled length of a pipeline or bundle of pipelines and molds that are continuous, or directly to one another along and around the assembled length, before it has been placed at its final destination. |
