Hari Vamadevan, Regional Director UK & Ireland, Senior Vice President with DNV’s Energy Systems business area, states: “We are seeing globally the drive from industry and governments to proceed with CCS and all major routes to successfully decarbonizing gas rely on the large-scale uptake of the technology. This RP gives guidance to the industry to contribute and ensure that safe and reliable operations continue to take place as CCS begins to scale worldwide. It also supports the fact that the re-purposing of existing infrastructure can be carried out safely in the future.”

Transport of CO2 can be done either through the use of existing pipelines or the construction of new pipeline systems. DNVGL-RP-F104 is supporting both the design of new pipelines and the reuse of existing infrastructure by describing a process of how to re-qualify the pipelines for CO2 transport through various steps. Requirements for re-qualification is primarily identified through a change of medium in the pipeline, for example, from natural gas as in the original design, to CO2.

Both for new CO2 pipelines and re-qualification of existing pipelines, the operators of the pipelines need to fully understand the threats, failure mechanisms, consequences and probabilities of pipeline failures in order to ensure that they are operated safely.
