Jan De Nul Group has signed a contract with Sumitomo Electric Industries for the installation of two subsea HVDC cables and one fibre optic cable that will link the existing electricity grids in Ireland and the UK.The subsea cable route for the 500MW 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. Greenlink is a subsea and underground electricity interconnector linking the power markets in Ireland and Great Britain and due for commissioning in 2024.
