High frequency monitoring buoy

Bouée houlomotrice de monitoring


The SMILE project is an High Frequency instrumented wave energy buoy. This operational prototype wave energy buoy is the result of a partnership between Ifremer, The University of Caen, and nke-instrumentation. The project is co-funded by the Water Agency Seine Normandie and Basse-Normandie ERDF.

This measuring buoy is undergoing certification by the SOMLIT network implemented by the CNRS. It provides data every 20 minutes and subsurface (-1,50m).

On-board equipment:

  • Multiparameter probe (T ° C, salinity, DO, Fluorimetry, turbidity)
  • PAR Sensor
  • PAM Production Sensor Primary
  • Weather Channel.

The project partners were looking for a compact float able to guarantee a high energy production and overcome availability problems, detected by previous programs with 100% solar buoys.

GEPS Techno has provided its wave energy buoy OCTOPUSEA solution and coordinated the integration of different means of measurement on the float.
