Groix & Belle-Île buoy assembly

A buoy to study biofouling

Preparations are underway to launch a 2-tonne buoy on the exposed North Atlantic site of the future Groix & Belle-Île pilot farm. Once deployed and instrumented, this equipment will enable studies on biofouling to be carried out in the framework of two collaborative projects: APPEAL and ABIOP+.

This rather unusual buoy was dimensioned by Cerema and designed by France Energies Marines, under the scientific supervision of the University of Western Brittany. Its originality lies in its double mooring system: the first line is used for on-site stowage at a depth of 65 m, the second is equipped with self-orienting collecting frames, fixed every 10 m for the study of biocolonisation as a function of depth, and outriggers to prevent the two chains from becoming entangled. The procedure for launching the buoy is currently being finalised.

The operations will continue in a few weeks…
