Arcadis Ost 1 monopile foundation contract awarded to Steelwind

In the presence of Lower Saxony’s Minister for Environment and Energy, Olaf Lies,  Parkwind and Steelwind have signed a contract for the fabrication of the monopile (MP) foundations for the Arcadis Ost 1 offshore wind farm this Friday, July 3rd, at Steelwind HQ in Nordenham, Germany.

This signature follows the recently announced OSS contract with Bladt and further secures Parkwind’s planning for the project.

As one of the key market players in monopile fabrication, Steelwind will deliver 27 WTG and one OSS next generation XXL-Monopile units.

Arcadis Ost 1 Project Manager, Clément Helbig de Balzac from Parkwind commented: “We believe the signature of this agreement sends a strong positive message during a difficult COVID-19 context. The impact generated by this contract fits into EU’s Green Deal initiative and demonstrates the offshore industry’s role in helping Germany reach its ambitious CO2 reduction targets as well as in stimulating the economy and local employment during a particularly difficult COVID-19 context. ”

Dr.Ralf Hubo and Alexander Morber, managing directors of Steelwind added: “These single-piece monopile foundations beyond XXL will be the biggest monopiles so far for German windfarms. The integration of some parts of the transition piece into the monopiles offers a new chance to reduce costs although the dimensions are really large. Our fabrication technology is very well adapted to these kind of monopiles and we are very proud that we have got this innovative order from Parkwind.

The monopile production starts 2021. Europe’s leading producer of heavy plate Dillinger will supply the heavy steel plates for the monopiles.

About Steelwind Nordenham GmbH

Steelwind Nordenham GmbH, a Dillinger Group company, has been manufacturing monopiles and transition pieces in Nordenham since 2015, and now also produces “single-piece” monopile foundations with unit weights of up to 2,400 metric tons. The single-piece monopile foundation replaces the previous design with a separate monopile and transition piece by integrating certain parts of the transition piece into the monopile. The monopile can then be up to 120 meters long. The steel for the foundations comes from Dillinger – the European heavy plate market leader located in Saarland. For more information, see
