Utilising double block isolation tools to reroute live pipelines without affecting production
Abstract
There are many reasons for rerouting or removing a section of pressurised pipeline, this can be due to city expansion where highly critical pipelines are relocated away from densely populated areas or at river crossings where buried pipelines have become damaged due to riverbed movement. Additionally, as pipelines reach the end of their design life they are required to be replaced or decommissioned.
As global demand for energy increases so do the consequences of any potential pipeline outage. Interference to this flow can have major consequences both commercially for the operator and more critically a potential shortfall in fuel supply to the client.
In cases where pipelines are required to be rerouted, without suitable double block isolation tools installed, it will be necessary to depressurise the entire section of pipeline to allow safe rerouting of the new section.
This webinar will discuss proven double block and bleed isolation technology that can be utilised to minimise or prevent shutting down critical pipelines while safely removing or rerouting pressurised pipelines.
