Jan De Nul Group carried out the transport and installation of all wind turbines and monopile foundations at the Saint-Nazaire offshore wind farm, using the jack-up installation vessel Vole au vent. Jan De Nul also performed preparatory seabed works (rock fragmenting/seabed smoothing) with the cutter suction dredger Fernão de Magalhães to enable safe jacking and installation on uneven rocky seabed conditions at Banc de Guérande.
