Amprion has begun preparations for offshore cable installation for the 900MW DolWin4 grid connection project around Norderney in Germany.
The company said work will start with site setup in early May before cable installation at Oase beach and the nearshore area.
Amprion added that cables will be laid across the exclusive economic zone, coastal waters and onshore between the coast and Lingen.
Prysmian has been contracted for cable manufacturing and installation following approval for an early construction start under environmental conditions.
Cable laying at the beach is expected to begin in late May or early June, with completion scheduled for early July.
The project involves installation using the vessel Prysmian Marco Polo and the cable laying barge Barbarossa I, which will bring cables ashore and lay them along the beach before burial.
“The early start of construction is good news for tourism on the island: we can keep a large part of the restrictions out of the main holiday season in July and August,” said Stefan Sennekamp, project spokesperson at Amprion.
“So we can ensure that the impact on nature is reduced to a minimum.”
After beach works, installation will continue in the Wadden Sea and Riffgat fairway, with further cable laying activities expected from mid-August.
Amprion said DolWin4 and BorWin4 are scheduled to enter operation in 2028 and will replace 1.8GW of generation capacity with offshore wind energy.
The company added that BalWin1 and BalWin2 grid links, with 2GW capacity each, are also planned to connect North Sea wind farms to the transmission network by 2030 and 2031.
