Unique Pipeline Isolation Application During Platform Upgrade in the East China Sea

Offshore pipeline isolation involves temporarily blocking a section of the pipeline so that maintenance, repairs or modifications can be performed safely without having to remove the pipeline content or shutting down production for a longer period. The isolation process can be challenging in an offshore environment due to several factors including variable weather and harsh sea conditions, accessibility or with operation taking place partly subsea. In the case study below, the isolation solution and the technical expertise of TDW provided multimillion-dollar savings in potential lost production while maintaining safe isolation for more than 80 days to facilitate modification work at the offshore platform. The method involved the deployment of a Dual Module SmartPlug庐 isolation tool with gas production diverted through a bypass line on the gas export riser during the construction period.
