The first offshore wind turbine was installed in April and the wind farm delivered its first power to the French national grid a couple of months ago.

Louis Dreyfus TravOcean (LDTVO) finished with the installation of all 80 inter-array cables at the 480 MW Saint-Nazaire last month for which the company used its cable-laying vessel Olympic Triton.

Back in 2018, Louis Dreyfus TravOcean (LDTVO) and Prysmian secured the contract for the supply and installation of inter-array cables.

Under the agreement, Prysmian was responsible for cable manufacturing, while LDTVO is responsible for transporting the cables to the Montoir-de-Bretagne logistics base, storing, and installing them between the wind turbines.

At the end of May, all 80 foundations were installed using DEME Offshore’s installation vessel Innovation.
