Eiffage Secures Second Contract for Offshore Platform in the North Sea

A Second Conversion Platform Awarded by 50Hertz

Eiffage, through its Belgian subsidiary Smulders and as a member of the joint venture NSORe (Neptun Smulders Offshore Renewables), has been designated by 50Hertz, which manages the transmission network in northern and eastern Germany, for a second contract concerning an offshore conversion platform.

NSORe is an equal partnership joint venture between Smulders and Neptun Werft, a subsidiary of Meyer Werft, dedicated to HVDC (high voltage direct current) offshore substation projects. The new contract concerns the construction of a 2 gigawatt conversion platform intended for the LanWin3 project in the North Sea.

Turnkey Delivery and Distributed Manufacturing

As with the LanWin6 project, Siemens Energy will be responsible for supplying the high voltage components for the LanWin3 project. NSORe is responsible for the complete implementation and turnkey delivery of the facilities, which includes overall system design, component procurement, construction, installation onshore and offshore, as well as commissioning.

Key components, such as the topside (main structure of the offshore platform), must be built at the NSORe shipyard in Rostock-Warnemünde. Smulders will manufacture the steel substructure (jacket) at its own shipyard in Flushing, the Netherlands.

A First Contract Awarded in June 2026

In June 2026, NSORe, within a consortium with Siemens Energy, had already been awarded by 50Hertz the contract for the construction of a 2 gigawatt conversion station for the LanWin6 offshore grid connection project.

According to Eiffage, these two contracts will enable the generation of offshore wind electricity volumes from the North Sea for the German electrical grid and strengthen NSORe's positioning in offshore wind projects.
