Corinth Pipeworks is awarded a pipe manufacturing contract for the Porthos offshore Carbon Capture & Storage project in the Netherlands





Brussels, 18 October 2023


Cenergy Holdings announces that Corinth Pipeworks, its steel pipe segment, was awarded a contract in excess of EUR 30 million, to manufacture and supply High Frequency Welded (HFW) steel pipes for the Porthos CO2 transport and storage project.

The 16-inch, 22-kilometer offshore pipeline will include anti-corrosion coating, thermal insulation, as well as concrete weight coating (CWC).  The pipeline will transfer CO2 from a compressor station to the P18-A platform in the North Sea.  The existing gas platform P18-A will be repurposed for CO2 storage.  The platform will be outfitted with the necessary equipment for transporting the collected CO2 to the injection wells. The pipes will be manufactured at Corinth Pipeworks’ facilities in Greece, and offshore installation work will commence according to schedule within 2026.

Carbon Capture and Storage (CCS) is a low-cost method of preventing huge volumes of CO2 from entering the atmosphere with permanent storage in geological reservoirs. CCS is a crucial strategy to help accomplish climate targets, particularly if the industry has few options for making major short-term CO2 emission reductions. Once operational, the Porthos project intends to permanently store CO2 from industry in the Port of Rotterdam in empty gas fields deep beneath the North Seabed.  

CCS technologies have the potential to play a significant and diverse role in achieving global energy and climate goals. The European Union has recognized Porthos as an important project in meeting climate targets, designated it a Project of Common Interest and made €102 million in funding available for it.

For the past 15 years, Corinth Pipeworks has manufactured pipelines transporting CO2 totaling over 1,150km in length. The company’s North American onshore and now European offshore CO2 pipeline experience demonstrates its readiness to contribute to the development of many planned CCS projects around the world.
