ZWIJNDRECHT, BelgiumPrysmian has awarded DEME two engineering and installation contracts for the IJmuiden Ver Alpha and Nederwiek 1 offshore grid systems in the Dutch North Sea.

It is DEME’s most extensive cabling award to date and its first involving Prysmian’s 525-kV HVDC cable technology, designed for increased transmission capacity.

The workscope covers cable installation, landfall and rock placement, dredging, and marine infrastructure activities. DEME will install two 12-km-long 525-kV HVDC cable systems across the Veerse Meer and 126 km of a 525-kV HVDC cable system offshore.

For IJmuiden Ver Alpha, the company will perform route preparation, surveys, landfalls and rock placement, and pre-sweeping/rock placement works for the Nederwiek 1 project.

DEME will deploy cable installation vessels, hopper dredgers and a fallpipe vessel from its fleet. The project scope also covers the beach works and cofferdam structures at the cable-landing locations.

Works will take place in stages from 2025.

IJmuiden Ver Alpha and Nederwiek 1, both operated by TenneT, will link two future offshore wind farms in the Dutch North Sea to the province of Zeeland in the southwestern Netherlands. The first connection should be operational in 2029 and the second in 2030.
