France – The installation of 80 foundations at the Saint-Nazaire offshore wind farm in France was completed by DEME Offshore and Eiffage Métal.
To install the foundations in solid rock and increase operational working time, industry-first technology was used. The foundations were started in the spring of 2021. DEME and its partner Herrenknecht collaborated on the design of a 350-tonne Offshore Foundation Drill (OFD) for the XL monopile drilling. The MODIGA is another unique piece of equipment stationed in Saint-Nazaire.
The MODIGA, which stands nearly 60 meters tall, encloses the drilling and installation operations, protecting them from the harsh Atlantic marine conditions and increasing operational working time. The offshore installation vessel Innovation has deployed the entire technological solution.
The Saint-Nazaire wind farm will have a total capacity of 480 MW, which is enough to meet 20% of the electricity needs of the French department Loire-Atlantique. EDF Renouvelables, Enbridge, and CPP Investments are developing the wind farm.
