New CO2 transportation standard

DNV, together with major industry partners, is developing a new standard for transportation of CO2 in pipelines. Specific issues related to CO2 in dense, high-pressure phases are not covered in existing pipeline standards or regulations. Relating to CO2 pipeline transmission, stakeholders today demand a robust, traceable and transparent approach that gives credibility to the proper management of the risks and uncertainties. Unfortunately, the current pipeline standards do not take into account considerations related to the pipeline transmission of CO2 from large-scale capture plants to suitable storage sites. This serves as a barrier to the effective large-scale deployment of CCS. DNV has therefore initiated a specific industrial collaboration to develop a standard reference guideline for the onshore and submarine pipeline transmission of dense, high pressure CO2. The project’s partners are StatoilHydro, BP, Shell, Petrobras, Vattenfall, Dong Energy, ArcelorMittal, Gassnova, Gassco and ILF. The Technical Reference Group consists of government representatives from the UK, The Netherlands and Norway. The European Commission is also supporting this DNV initiative. The guideline is intended to help designers and operators limit and manage uncertainties and risks related to the pipeline transmission of CO2 by incorporating current knowledge related to both offshore and onshore operations. It will state rules for managing risks and uncertainties throughout the pipeline’s lifetime, including the design, testing, inspection, operation, maintenance and de-commissioning phases. It will also incorporate the lessons learned from existing and previous projects.
