Transmission system operator TenneT has awarded a cable supply contract worth around €140m to Prysmian for the 900MW Dolwin 5 offshore grid connection in the German North Sea.
DolWin5 is set to go live in 2024 and will connect the wind farms Borkum Riffgrund West I and II and Northern Energy OWP West to the grid.
The contract involves the supply, installation and commissioning of a high-voltage direct current 320 kilovolt submarine and land power cable connection.
The Italian company would also supply an associated fibre optic cable system, comprising a land route of 30km and a subsea route of 100km.
Cable will be manufactured at Prysmian facilities in Pikkala, Finland and Gron, France and installation will be handled by cable-laying vessels Cable Enterprise and Ulisse.
Completion of the cable project is scheduled for the middle of 2024.
“The Dolwin5 project continues our valued long relationship with the major TSO TenneT and demonstrates our ability to provide tailor-made submarine cable solutions for challenging projects,” Prysmian executive vice-president projects Hakan Ozmen said.
TenneT chief operating officer Tim Meyerjürgens said: “We recognise Prysmian as an experienced partner with whom we will be able to accomplish this important energy transition project successfully.”
Danish wind farm developer Orsted is planning to bring the 660MW Borkum Riffgrund West 1&2 and 240MW OWP West projects online in 2024 and 2025.
