‘Orion’ has now installed the 1,300-tonne jacket and the 2,200-tonne topside, completing the project on schedule on August 11. Just four months previously, DEME carried out the pre-installation of the offshore substation’s foundations utilising another member of the fleet, the DP2 jack-up vessel ‘Sea Installer’. DEME Offshore used its subsea template to achieve a seamless installation in challenging environmental and soil conditions.
In August 2021, DEME installed the very first offshore substation in France at the Saint-Nazaire offshore wind farm, deploying Allseas’ heavy lift vessel ‘Pioneering Spirit’. The Fécamp and Saint-Nazaire successful substation installations bear witness to DEME Offshore’s capability to carry out technically demanding and pioneering projects. Transmission Substation
Fécamp’s electrical substation was constructed by a consortium including Atlantique Offshore Energy, the business unit of Chantiers de l’Atlantique dedicated to renewable marine energies, GE Grid Solutions and DEME Group’s French subsidiary SDI.
