Eiffage, through its subsidiary Smulders, was awarded by RTE an EPCIC (engineering, procurement, construction, installation and commissioning) contract to develop and build three 750 MW alternating-current offshore substations to connect the Bretagne Sud (AO5), Narbonnaise Sud-Hérault and Golfe de Fos (AO6) offshore wind farms and their future extensions (AO9, including Golfe de Fos 2). The scope includes design and construction of jacket foundations and topside structures housing the electrical equipment. For the Narbonnaise Sud-Hérault and Fos substations, jackets are approximately 110 m high and topsides weigh about 5,000 tonnes; jackets are to be assembled at Eiffage Métal’s Fos-sur-Mer site and topsides assembled in Vlissingen (Netherlands). The overall contract value was stated as more than €1.5 billion.
