DNV, along with other industry partners, has developed the world’s first guideline for the transmission of CO2.

Its unified approach will ensure that CO2 is transmitted in offshore and onshore pipelines in a reliable, safe and cost-effective manner.

Existing pipeline standards had to be extended to incorporate specific guidelines for the transmission of CO2.

The joint industry project, named CO2Pipetrans involved partners Arcelormittal, BP, Chevron, Dong Energy, Gassco, Gassnova, ILF, Petrobras, Shell, StatoilHydro and Vattenfall.

Special acknowledgement is also given to representatives of the Health and Safety Executive in the UK, the State Supervision of Mines in the Netherlands and the Petroleum Safety Authority in Norway.

The head of the Carbon Capture and Storage section at DNV, Froydis Eldevik, explains that the guideline provides guidance and sets out criteria for the development, design, construction, testing, operation and maintenance of steel pipelines.

It applies to offshore and onshore pipelines for the transportation of fluids containing CO2, the conversion of existing pipelines, the pipeline transportation of CO2 captured from hydrocarbon streams and from anthropogenic CO2 (from combustion processes and capture facilities), the pipeline transportation of natural (geological) sources for the purpose of enhanced oil recovery, and to other larger scale transportation of CO2.

Gaseous, liquid and dense phase operation conditions are included.

The guideline will be a supplement to current pipeline standards like ISO 13623, DNV OS-F101, ASME B31.4 and others.

It will provide support relating to specific CO2 transportation issues for carbon capture and storage developers, pipeline engineering and construction companies, pipeline operating companies, authorities and certification companies.
