DEME Offshore has announced that it has reached its halfway installation milestone with foundation installation for the Saint-Nazaire offshore wind farm in France. Since starting construction in Spring 2021, 40 out of a total of 80 XL foundations are now installed.

For the installation, DEME Offshore for the first time is deploying its 350-tonne Offshore Foundation Drill (OFD). It is also using its tailor-made ‘MODIGA’ system which supports the drilling and installation operations by shielding them from the adverse Atlantic marine conditions.

The OFD was developed with Herrenknecht and the design and development of the MODIGA happened together with TMS. The complete technological solution is being deployed from DEME Offshore’s installation vessel ‘
Innovation’ .

“Today’s achievement is a testament to the commitment of our entire team and solidifies our reputation as the number one wind farm contractor in the world. Not only are we the first to install a wind farm in rock with industry-first technology, the Saint-Nazaire project is also being carried out in harsh Atlantic conditions. Together with our client Parc éolien en mer de Saint-Nazaire and our partner Eiffage Métal, we will continue our excellent cooperation for the remaining foundations,”
said Bart De Poorter, General Manager DEME Offshore.

The 480 MW
Saint-Nazaire wind farm, currently owned by EDF (50%), Enbridge (25.5%) and CPP (24.5%), is expected to be fully commissioned by the end of 2022. It is located between 12 and 20 kilometres off the Loire-Atlantique coast. It will consist of 80 GE Haliade 150-6MW wind turbines. According to GE, each Haliade turbine powers 5,000 homes; the project is expected to generate the equivalent of 20% of the Loire-Atlantique’s electricity consumption.
