Asso.subsea Ltd. was awarded on 11 January 2023 by Hellenic Cables (the cable turnkey contract holder) the transportation, installation, and protection contract for the single 220 kV export submarine cable system on Ostwind 3. The scope covers more than 100 km of route from the Jasmund offshore substation through the Bay of Greifswald to landfall near Vierow/Lubmin, including shallow waters, HDD landfall pull-in, boulder fields, third-party cable/pipeline crossings, and varied seabed conditions.

This is a turnkey subcontract awarded by Hellenic Cables, not a direct contract with 50Hertz, and the role is linked to Hellenic via client_organisation_id.
