Axess Technologies has been awarded a cable installation contract by Greece-headquartered Hellenic Cables for the Ostwind 3 grid connection project, located in the German Baltic Sea.
The scope of work comprises planning and pulling internal platform cables into the offshore high-voltage (HV) substation, covering both 66 kV and 220 kV cable systems .
The engineering phase is already underway, with the execution phase scheduled to begin in the second quarter of 2025 at HSM’s Stormpolder yard in the Netherlands, said Axess Technologies.
Ostwind 3 is being developed by the German transmission system operator (TSO) 50Hertz. The Dutch-Belgian joint venture (JV) comprising HSM Offshore Energy, Smulders, and Iv-Offshore & Energy is responsible for the delivery of the HV offshore substation for the Ostwind 3 grid connection project.
In October 2022, 50Hertz awarded Hellenic Cables a contract for the design, supply, storage, installation, jointing, termination, testing, and commissioning of a 105-kilometre submarine three-core export cable (220 kV) as well as 13.5 kilometres of onshore export cable, a 2-kilometre platform cable (220 kV), and a 2-kilometre platform cable (66 kV).
The Ostwind 3 project will connect a segment of the Windanker offshore wind farm, developed by Iberdrola, to the German extra-high voltage transmission grid.
Once completed in 2026, a capacity of 300 MW of renewable energy will be supplied to the German grid, enough to power around 260,000 households, according to Axess Technologies.
Located in the Baltic Sea next to the island of Rügen, the Windanker offshore wind farm will comprise Siemens Gamesa 15 MW wind turbines installed on top of monopiles supplied by the consortium of Navantia Seanergies and Windar Renovables.
