The Arcadis Ost 1 wind farm is developed by the Belgian offshore wind specialist Parkwind and has a capacity of 257 MW. The 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 metres long and weigh around 2000 tonnes each, making them 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.
DEME Offshore will deploy the DP3 offshore installation vessel ‘Orion’ for this project. ‘Orion’ is a front runner in the industry - effectively a mega monopile installation machine - and will be equipped with a tailor-made, motion compensated gripper system able to handle enormous foundations of up to 2,500 tonnes.
“Being awarded such a pioneering project highlights how Parkwind has confidence in the game-changing DP3 offshore installation vessel ‘Orion’” said Bas Nekeman, Business Unit Director DEME Offshore. “DEME Offshore is delighted that it will be the first company to install these XXL monopiles, as the offshore wind industry takes the next step forward. With ‘Orion’ we will be strongly positioned to offer solutions for the installation of larger foundations and turbines, and large-scale wind farm projects such as Arcadis Ost 1, delivering energy at lowers costs.”
Clement Helbig de Balzac, Arcadis Ost I Project Manager, added that the signing of the foundation EPCI contract with DEME Offshore is another important step towards the realisation of Arcadis Ost I and that the project is pushing the limits of what has been done to date in offshore wind in terms of foundation technology. It was therefore key for the project’s success to select a strong and highly experienced EPCI contractor such as DEME Offshore, deploying state of the art installation vessels and technology.
Production of the monopile foundations will start in 2021, while the installation campaign is planned to start before the summer 2022. Arcadis Ost 1 is scheduled to be fully commissioned in 2023.
