Ecole Centrale de Nantes (ECN) leads the project management and realisation of SEM-REV. The wave energy test site program is registered as the French Project contract  “Etat Région 2001-2013".

ECN and CNRS are actively committed to the development of marine energy devices through the research laboratory in Hydrodynamics, Energy and Atmospheric Environment (LHEEA). As such, ECN plays an important role in the evolution of new energy production systems.

To this end, ECN has been in charge of :

- obtaining the concession for the 1km² test site (0.39 mile²),

- preventing navigation by beaconing and delimiting the test area,

- equipping the site with an extensive measurement network in order to obtain high-quality wave, current and weather data across the facility,

- investing in an oceanographic vessel for an easy and fast access to the test site during maintenance operations.

The geographical area used for the project was selected based on several feasibility studies involving technical and economical constraints and ease of access. The 1km2 wide offshore area is located north of Le Croisic peninsula and faces the Guérande Bay. The site selection was also completed by a public consultation with the local population and the users of the maritime domain.

The zone is precisely situated:

  • 6.5 nautical mile south west (225°) of the "Four" lighthouse
  • 10 nautical mile West-South-West (252°) of Le Croisic’s cape
  • 5.4 nautical mile South-South-West (202°) of “grands cardinaux” (Island group of Hoëdic)

The onshore facility will welcome scientists and research staff as well as all sort of emission/reception devices (antennas, etc.). It will be also connected to the French national electrical network EDF.

The wave energy prototypes will be connected to four possible berths within the test site.

A submarine cable with fiber optics will permit the electric connection to the shore in order to collect and drive the energy produced by the devices to the substation.

The facilities for monitoring and controlling the systems are currently available on the site.

The electrical network of the SEM-REV has been constantly reconsidered and optimized.

The final decision for the site's construction has been taken by a joint committee composed of the project management team and subcontractors who have worked for the program.
