The continuous development of the remote controlled high pressure pipeline isolation technology has resolved a range of operational problems caused by faulty pipeline valves and fittings. Recent applications includes change of a faulty insulation joint on a 42” pipeline in Georgia, rerouting of the Frigg and Heimdal to St. Fergus pipelines during Frigg Decommissioning, repair of a faulty subsea clamp on a 26 inch pipeline in GOM, all on live pressurized gas pipelines. The piggable high-pressure isolation train can include a pressure test barrier allowing leak test or pressure test upon completed repair work. Other recent applications include protection of pressurized pipelines during heavy lift operations. This paper describes a range of application focusing on the time and cost saving achieved by the operator whilst minimizing environmental impact.
