Van Oord to install RWE’s Nordseecluster foundations

Van Oord has been awarded the contract for the transport and installation (T&I) of the monopile foundations for the 1.6 GW Nordseecluster offshore wind project in Germany. The news follows after RWE announced the final investment decision for the projects yesterday.

Van Oord’s scope includes the installation of 104 extended monopiles as well as the installation of the scour protection. In 2025, 44 monopiles are planned for installation in 2025 and the remaining 60 monopiles in 2027. The monopiles are manufactured by Dajin Offshore. They will support the Vestas 15 MW wind turbines.

First time for Boreas

This project award is a major milestone for Van Oord because it will be the first project for the brand-new offshore installation vessel Boreas, which is currently under construction.

The Boreas will be the largest offshore installation vessel of its kind, purpose-built for the transport and installation of the next generation foundations and turbines for offshore wind farms. The jack-up vessel, with a crane capacity of more than 3,000 tonnes, can install up to 20 MW wind turbines at sea. It has the capability to fully operate on methanol, drastically reducing its carbon footprint. Green methanol is one of the most promising future fuels as it is produced using only renewable energy sources. As such, it can reduce the carbon footprint of Boreas by more than 78%. This is in line with Van Oord’s ambition to reduce emissions and to achieving net-zero emissions by 2050.


The Nordseecluster is located in the eastern part of the German part of the North Sea, about 50 kilometers north of the island of Juist. The Nordseecluster is being implemented in two phases – Nordseecluster A and B. Nordseecluster A has a total capacity of 660 MW. Manufacturing of some key components has already started. Construction at sea is scheduled to begin next year. By the beginning of 2027, all 44 wind turbines shall be connected to the grid. Nordseecluster B will add a further 900 MW of capacity. The 60 turbines are scheduled to start commercial operation from the beginning of 2029. Source: Van Oord/ RWE
