Offshore staff
ARNHEM, the Netherlands — TenneT has awarded installation contracts covering 525-kV HVDC cable systems for offshore wind developments in northwest Europe.
The contracts, with a combined value of about €5.5 billion ($6.06 billion), went to NKT, Nexans and a consortium of Jan De Nul, LS Cable and Denys.
NKT will manage the connections for Nederwiek 3, landing onshore at either Geertruidenberg or Moerdijk, and also the connections for Doordewind 1 and Doordewind 2, landing at Eemshaven.
Nexans will connect cables for BalWin3 and LanWin4 at Wilhelmshaven and LanWin2 in Lower Saxony, in the Heide area in Schleswig-Holstein, northern Germany.
The consortium of Jan De Nul, LS Cable and Denys will implement connections in Lower Saxony, to BalWin4 and LanWin1, both to be linked in the Unterweser area, and LanWin5 in the Rastede area.
The same group will handle the TenneT part of the onshore 525-kV DC corridor NordOstLink in Schleswig-Holstein, where the other partner is 50Hertz.
The scope of work for these programs covers cable design, engineering, production, delivery, project management, offshore-, onshore- and nearshore installation of 525-kV HVDC cables, and all jointing works in the submarine sections and on land. Activities should start this year, with offshore cablelay taking place in 2026.
All 2-GW offshore projects should be operational by 2031.
