Jan De Nul Group has signed a contract with Sumitomo Electric Industries, Ltd. (Sumitomo Electric) for the installation of two subsea HVDC cables and one fibre optic cable that will link the existing electricity grids in Ireland and the United Kingdom.

Jan De Nul is responsible for the end-to-end subsea cable laying and cable protection works. At the shore sides, Jan De Nul will perform the Horizontal Directional Drillings starting later this year in 2022. The offshore installation campaigns will be performed in 2023 and 2024. 

Greenlink is a subsea and underground electricity interconnector linking the power markets in Ireland and Great Britain and is due for commissioning in 2024. Being awarded the status of Project of Common Interest by the European Union, it is one of Europe’s most important energy infrastructure projects, bringing green electricity to approximately 380,000 homes.
