Corinth Pipeworks is awarded the contract for the N05-A pipeline






Brussels, 28 March 2023


Cenergy Holdings announces that Corinth Pipeworks, its steel pipes segment, was awarded a contract by ONE-Dyas B.V. to provide High Frequency Welded (HFW) steel pipes for the N05-A platform.

The N05-A platform is located in the North Sea, about 20 km north of the Ems estuary.  This offshore gas production project will run entirely on renewable energy from the nearby Riffgat wind farm, which actively contributes to the energy transition and the achievement of the Paris Climate Agreement’s goals.

The contract covers approximately 16km of 20” diameter High Frequency Welded (HFW) pipeline, and includes external 3-layer polypropylene and concrete (cement) weight coating applied at the same location as pipe manufacturing.  The HFW pipes will be manufactured in Corinth Pipeworks’ facility in Greece and will be delivered within 2023. 

Furthermore, the pipeline will be certified according to the ASME B31.12 option B certification code for hydrogen pipelines, supporting the plans for future transportation of up to 100% hydrogen.

This project is important in the effort to reduce the environmental footprint of natural gas production with the assistance of electricity from renewable sources, such as offshore wind farms. Electricity from the wind farm will be able to be converted into green hydrogen and transported via pipelines to the onshore grid.
