ZWIJNDRECHT, Belgium – Parkwind has awarded DEME Offshore an EPCI contract for the foundations for the Arcadis Ost I wind farm offshore Germany.

The 257-MW wind farm will be located in the Baltic Sea, northeast of the island of Rügen in the coastal waters of Mecklenburg-Vorpommern, Germany.

Manufactured by Steelwind in Germany, the 28 XXL monopile foundations will be about 100 m (328 ft) long and weigh around 2,000 metric tons each. According to DEME, the XXL monopiles will be the largest ever installed in Europe.

One of the 28 foundations will support the offshore substation. The monopiles for the wind turbines will not be equipped with common transition pieces but will have a direct connection with the turbine tower, the company said.

The company will deploy the DP-3 offshore installation vessel Orion for this project. The vessel will be equipped with a tailor-made, motion compensated gripper system able to handle foundations of up to 2,500 metric tons.

Production of the monopile foundations is expected to start in 2021, while the installation campaign is planned to start before the summer 2022. Arcadis Ost I is scheduled to be fully commissioned in 2023.
