This accompanying measure concerns the testing of a system to avoid bird collisions with the blades of operating wind turbines. The system consists of a network of cameras, which detect the trajectories of different categories of birds, connected to a sound scaring system, which is activated once a bird enters a risky perimeter around the turbine rotor. Various systems are available on the market and have been operational for a number of years on onshore wind farms. Marine-based versions adapted to offshore sea conditions are currently being developed, however they do not benefit from as much feedback as their onshore counterparts. For this reason, the choice of system has not been fixed in the prefectoral authorization decrees.
This measure aims to test an existing system, at a rate of 3 devices each attached to a wind turbine, distributed at the south and north ends as well as in the centre of the wind farm (see figure below).
Ailes Marines has approached potential suppliers and a call for tenders will be issued shortly.
