Between June and November 2020, teams from Université Bretagne Sud (UBS) and Morbihan Hydro Energies carried out a series of hydrodynamic measurement campaigns and environmental characterisation of the Morbihan site in Brittany, France.

From 1 May to 16 June 2020, UBS, Morbihan Hydro Energies, along with Alpha & Co deployed an Acoustic Doppler Current Profiler (ADCP V50) to collect currents and wave data over a period of six weeks. The measures of this ADCP deployment will be used to validate hydrodynamic modelling of Sabella D8 turbines that will be installed on the site as part of the TIGER project.

Also, from 5 June to 16 November 2020, the UBS team carried out two measurement missions on the intertidal zone of the landing site of the experimental tidal energy project in Morbihan (Arzon Municipality).

The main objectives of these two missions were to obtain information on:

  • Morphological and altimetric characterisation of the site (photogrammetric monitoring by drone)
  • Sedimentary characterisation of the site (cores and sedimentary sampling)
  • Inventory of the fauna and flora of the site (cores and quadrat sampling)

The information gathered will strengthen the environmental knowledge on the site. Furthermore, this initial environmental characterisation of the site would provide elements for the Morbihan Data Centre and constitute the baseline for the environmental monitoring of the site that will be set up following the installation of the two turbines on the site.
