SEM-REV, Offshore multi-technology test site

SEM-REV is Centrale Nantes' offshore test site. It has all the equipment on- and off-shore required to develop, under operational conditions, marine energy recovery systems - mainly from offshore wind and wave. It will play a decisive role in developing this new industrial sector in France.

Missions

• Provide a dedicated site for technology installation and operations. 
• Manage the resale of electricity produced by the prototypes tested.
• Store or redistribute electricity for off-grid projects
• Provide access to offices and data (meteorological / oceanographic and control devices) for test supervision.
• Maintenance of equipment and tools under operational conditions.
• Links with local marine stakeholders (users of the sea, state services, operators, marine authorities etc) and local players in the value chain (construction, installation, operation, sensors etc).
• Environmental impact assessment for both the test site and the devices.

• Land station: research centre and electrical substation.
• Export cable: 20kV and 24 fibre optics.
