DEME has been awarded two contracts from cable solutions provider Prysmian for engineering and installation work for the IJmuiden Ver Alpha and Nederwiek 1 offshore grid systems in the Netherlands
The company said that, combined, the deals are the most extensive cabling award in DEME’s history and the first involving the installation of Prysmian’s 525-kV HVDC cable technology, which provides increased transmission capacity compared with earlier technology
The company will be responsible for the engineering and installation of two 12-km long 525-kV HVDC cable systems in the Veerse Meer and 126 km of 525-kV HVDC cable system offshore. The work is scheduled to begin, in stages, in 2025.
DEME will also carry out preparatory and support work 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.
DEME will deploy a variety of vessels from its fleet, including cable installation vessels, hopper dredgers and a fallpipe vessel. In addition, the project will encompass the beach works and cofferdam structures at the cable landing locations.
IJmuiden Ver Alpha and Nederwiek 1 are offshore grid connection systems operated by TenneT that will link two offshore windfarms 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.
