DEME Offshore has completed installation of the foundation for the offshore substation for the 480MW Saint-Nazaire offshore wind farm off France.
The Sea Installer vessel carried out the work in record time, even though the four subsea foundation piles were drilled into rock in the challenging Atlantic marine conditions, the company said.
DEME Offshore said it used its in-house designed subsea template, tailor-made drilling equipment and methodology to accomplish this phase of the project.
“The lessons learnt from this achievement will be implemented for the next installation of the pile foundations for the Fecamp and Courseulles offshore substations,” the company said.
It added that the offshore installation vessel Innovation will now start installation of the 80 monopile foundations and XL monopile rock drilling at Saint-Nazaire.
A consortium of SDI/DEME Offshore, Atlantique Offshore Energy and GE Grid Solutions was awarded the EPCI contract for the electrical substation for Saint-Nazaire by Parc du Banc de Guerande.
Parc du Banc de Guerande is a subsidiary of Eolien Maritime France, a consortium made up of EDF Renouvelables and Enbridge.
