Deme Offshore and Eiffage Métal have completed the installation of 80 foundations at the Saint-Nazaire offshore wind farm in France. Installation of the foundations started in spring 2021.
Deme and its partner Herrenknecht, a provider of tunnel boring machines, jointly designed a 350-tonne Offshore Foundation Drill (OFD) to perform the drilling work for the monopiles. The company also deployed the Modiga. At nearly 60 m high, the Modiga encapsulates the drilling and installation operations, protecting them from the adverse Atlantic marine conditions. The complete technological solution has been deployed from the offshore installation vessel ‘Innovation’. The Saint-Nazaire wind farm will have a total capacity of 480 MW. The wind farm is being developed by EDF Renouvelables, Enbridge and CPP Investments.
