Deme has been awarded two contracts from Prysmian for the engineering and installation works for the IJmuiden Ver Alpha and Nederwiek 1 offshore grid systems in the Netherlands.
The contracts encompass cable installation, landfall and rock placement, dredging, and marine infrastructure works. This includes the engineering and the installation works of two 12-km long 525 kV HVDC cable systems within the lake "Veerse Meer" and 126 km of 525 kV HVDC cable system offshore. Additionally, Deme will carry out preparation and supporting works for IJmuiden Ver Alpha, comprising route preparation, surveys, landfalls and rock placement, as well as pre-sweeping and rock placement works for the Nederwiek 1 project. The works are scheduled to begin in stages from 2025.
IJmuiden Ver Alpha and Nederwiek 1 are offshore grid connection systems operated by TenneT that will link two future offshore wind farms in the Dutch North Sea to the province of Zeeland in the southwestern part of the Netherlands. The first connection will be operational in 2029, and the second in 2030.
