Germany, North Sea: Installation of the two offshore substation foundations for the Nordseecluster wind farm has been completed in the German North Sea, marking a major construction milestone for the project’s first phase.
RWE Offshore Wind confirmed that a jacket foundation, consisting of four piles and a transition piece, was successfully installed at the site at the end of last week. The structures were transported from the Port of Rotterdam, making an 18-hour journey before offshore installation.
Heerema Marine Contractors’ semi-submersible crane vessel Sleipnir performed the transport and heavy-lift operations for the components, each weighing over 2,000 t. The two substation topsides are scheduled for installation in 2026.
The offshore platforms are being built by Atlantique Offshore Energy, the marine energy division of Chantiers de l’Atlantique. Their foundations were supplied by Italy-headquartered Rosetti Marino, following a contract awarded in September 2023.
With the latest installation, all foundation structures for Nordseecluster A are now in place. This phase will deliver 660 MW using 44 Vestas V236-15.0 MW turbines and is expected to be fully operational in 2027. A second phase, Nordseecluster B, will add a further 900 MW through 60 additional turbines.
The Nordseecluster development is jointly owned by RWE and Norges Bank Investment Management, and will significantly increase offshore wind capacity supplied to the German electricity system.
