Parkwind, 50 Hertz and Bladt Industries have announced the installation of the offshore substation (OSS) for the
Arcadis Ost 1 wind farm. The 2380 ton structure was installed by the Scaldis crane vessel Gulliver on its monopile foundation.

The 30 metre high OSS in the center of the wind farm will collect the green power created by the 27 wind turbines, transform the power to a level of 220kV and export it onshore to the German 50Hertz grid connection point in Lubmin.

The substation's monopile foundation, with a weight of around 2100 tons, was erected on 8 June 2022. The final installation of the platform took place yesterday around 12 noon. In total, the offshore transformer platform together with its foundation weighs over 5,000 tons.

The OSS was designed, fabricated, and installed by the Danish contractor Bladt Industries. The substation was pre-fabricated in Poland and final assembly and equipment took place at Bladt Industries in Aalborg, Denmark from mid-2021. Semco Maritime provided design, installation and commissioning of the high, medium and low voltage equipment.

Manfred Dittmer, Parkwind’s Country Manager Germany, commented: “With the installation of the Arcadis Ost 1 substation, we reach another key milestone and maintain our tight installation schedule. We have surrounded ourselves with trusted partners like Bladt Industries and Semco to deliver an offshore substation of the highest-standards. Jointly developed with 50Hertz, this substation is a good example of European collaboration and is setting new standards for future offshore energy in Germany.”

Stefan Kapferer, CEO of 50Hertz, added: “I congratulate everyone involved on the successful installation of the Arcadis Ost platform in the Baltic Sea! We have thus reached an important milestone on the way to commissioning a great European joint project. As soon as our grid connection system Ostwind 2 goes into operation, more than half a million households will be able to be supplied with electricity from renewable offshore wind energy. This will increase our energy sovereignty, make us less dependent on fossil fuels and help us achieve our climate targets. We can't do this alone, but in good cooperation. We will steadily expand cooperation with our European partners in the coming years.”

Bladt Industries CEO Anders Søe-Jensen also commented: “We are pleased to have reached this important milestone in collaboration with our partner Semco Maritime. It is great to be part of another project for our customers Parkwind and 50Hertz, together contributing to the green energy transition and clean energy supply in Germany."

Arcadis Ost 1 wind farm will have a capacity of about 257 MW and is located in the Baltic Sea, 19 km north-east of the island of Rügen, within the 12 nautical mile zone of the Federal State Mecklenburg-Western Pomerania, Germany. Parkwind secured grid capacity for the project in the offshore wind auction in Germany back in 2018. Offshore installation works are expected to start works in 2022. It is expected to be operational in 2023, and will be capable of generating enough green electricity for the annual power consumption of more than 290,000 homes.
