Pipeline engineering specialist, STATS Group, has completed an isolation project on a 16” subsea pipeline in the Dutch sector of the North Sea on behalf of Wintershall Noordzee BV. The isolation enabled the client to disconnect a flexible gas export pipeline so it could be replaced with a new rigid gas export pipeline. STATS deployed its Tecno Plug tool for the isolation which prevented a costly depressurisation of the main trunk line, and reduced environmental impact, costs and production losses.
