Work kicks off for Calvados O&M base


Work on the Operation and Maintenance (O&M) base which will support the
Calvados offshore wind farm has kicked off at the Port of Caen-Ouistreham. The base will accommodate around one hundred people from 2023.

Construction of the foundations for the building and its framework is scheduled for completion in Spring 2022 followed by the shell of the building in summer 2022. The interior design work will then begin, which will continue until the end of 2022. The project team is expected to begin operations from the site in early 2023.

The maintenance base will consist of a control and telecommunications room, changing rooms, offices as well as a warehouse area to store equipment.

Since 2019 Ports de Normandie has been executing an investment program of nearly €28 million in the Port of Ouistreham. This includes the  installation of an entry system in the locks to accommodate larger ships and , an extension of 3 ha of the eastern pier to accommodate the future maintenance base for the Calvados offshore wind farm (€2.5 million).


In November 2021, the last phase of work (€9 million) began, involving, among other things, supporting the vessels transporting the operating and wind farm's maintenance staff.


Totalling an estimated €2 billion, the
Calvados project involves the construction of 64 wind turbines, located over 10 km off the French coast. With a capacity of 450 MW, it is expected to produce the equivalent of the annual electricity use of 630,000 people, i.e. over 90% of the population of Calvados. It is expected to enter service in 2024. It is being developed by Éolien Maritime France, a consortium including EDF Renewables, EIH S.à.r.l, (a subsidiary of Enbridge Inc., CPP Investments) and wpd.
