Offshore Windpark Arcadis Ost 1

Project: Offshore Wind Energy
Client: Parkwind NV
Location: Baltic Sea
Year: 2020 - 2023

Project description:

The Offshore Wind farm Arcadis Ost 1 is developed by Parkwind NV in the German economic zone of the Baltic sea. The windfarm is located at 19 km to the north-east of the island Rügen. Arcadis Ost 1 consists of 27 wind turbines from manufacturer Vestas of 9,5MW each. The turbines are connected by 7 strings of 33kV submarine cables. The produced energy is collected at the Offshore Station (OSS), where the voltage will be transformed to 225kV. And connected tow the German national grid, operated by TSO 50 Hertz. The OSS is developed and operated in cooperation with 50 Hertz.

Activities of Energy Solutions:

Energy Solutions delivered a significant contribution to the Arcadis Ost 1  project, commissioned by Parkwind NV. In the design phase, Energy Solutions contributed to the design and verification of the electrical infrastructure of the wind farm. During the construction phase, Energy Solutions supervised the installation of the electrical infrastructure. The following activities have been executed in cooperation with Parkwind NV:

  • Project support during the (pre-)engineering and tender process for the electrical infrastructure of the wind farm and support with the wind turbine manufacturer as well the grid operator on the 225kV grid connection at the OSS.
  • Calculations and simulations for the cable connections and grid connection
    Compose the technical specifications for the various contracts for procurement and installation of the 33kV submarine cables and the 33/225kV OSS.
  • Technical support during the tender process for the contracts mentioned above.
  • Project management as Deputy Package Manager Electrical Infrastructure during construction.
  • Project support during construction.
    Quality checks and factory acceptance tests of the 33kV/225kV Offshore Station.
  • Quality checks and factory acceptance tests of the 45 kilometre 33kV submarine cables connecting the wind turbines to the OSS.
  • Supervision of the commissioning of the electrical infrastructure.
