TenneT has commissioned subsea cable manufacturer Zhongtian Technology Submarine Cable (ZTT) for two offshore wind connections in Germany.
ZTT will deliver cable systems to link offshore wind farms to HelWin beta and DolWin kappa converter platforms in the North Sea, with the cable routes being five and 16 kilometre respectively.
The cable systems will be produced at ZTT’s manufacturing base in Nantong, China, and then transported to Europe, with the cable-laying operations to be carried out by the subcontractor asso.subsea from Greece.
The first cable laying is planned for summer 2022 to connect the Kaskasi II project and the second one is expected to take place the following year for the Gode Wind 3 offshore wind farm.
The connections will be for five and 16 kilometres, respectively, TenneT said.
The cable systems will be produced at one of Zhongtian s manufacturing facilities in Nantong, China, and then transported to Europe.
Installation will be carried out by Greek subcontractor Asso Subsea.
The first cable laying is planned for summer 2022 to connect Kaskasi 2 offshore wind farm.
Two cable systems with a conductor cross-section of 630 square millimetres will be used to transmit 342MW on the five-kilometre long route between the wind farm s transformer station and HelWin beta.
From the HelWin2 grid connection, electricity is transported over 130 kilometres to the land station at Buttel in Schleswig-Holstein.
