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. The subsea cable route for the 500 MW Greenlink Interconnector is about 160 km long between County Wexford in Ireland and Pembrokeshire in Wales.
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. Jan De Nul’s cable-laying vessel Connector will install the subsea cables which will predominantly be buried in the seabed. Where the seabed does not allow cable burial, the cables will be protected by the installation of rock or concrete mattresses on top of the cables.
Harada Kazuhira, Executive Officer and General Manager of Power Project Division at Sumitomo Electric: “We are delighted to be working with our partner Jan De Nul to build the Greenlink between Ireland and UK. This interconnector will form a critical part of the infrastructure to achieve net-zero emissions.”
Wouter Vermeersch, Manager Offshore Cables at Jan De Nul Group: “We are honoured to work alongside Sumitomo Electric to establish this important link for the electricity grids between Ireland and UK. Jan De Nul and Sumitomo Electric have been developing the installation solution in close collaboration over the last 2 years and we are now ready to fully engage in the actual realisation of it.”
