Wind Energy – Grouting
DEME Offshore and the grouting experts from former MBCC Group, now Sika, have signed an agreement on the supply of the grout material MasterFlow 9650 to the Noirmoutier offshore wind farm.
This highly specialized offshore grout will be used for the structural connections between the steel monopile foundations and the rock bed, the foundation will be anchored to. Furthermore, the grout will also be installed as skirt backfill between the transition piece and the monopile foundation.
The first supply of the MasterFlow 9650 grout is planned for early 2024 and the installation of the foundations in the rock bed will commence soon thereafter. It is estimated that the supply and installation will continue throughout a full year.
The Noirmoutier offshore wind farm will be located in the Bay of Biscay, approximately 17 km off the French coast near Challans and Saint Nazaire.
This wind farm will be constructed south of the neighbouring offshore windfarm St. Nazaire that was earlier already constructed by DEME Offshore. 61 foundations, of the grouted monopile/transition piece type with bolted connections, will be installed in this windfarm that has a total capacity of 496MW.
