High resolution local analysis of sea states and breaking waves variability from satellite imagery

Duration: 9 months


For offshore renewable energies (ORE) to integrate effectively into the French energy mix, it is essential that they increase their competitiveness in the short and medium term. The under- and overdimensioning of energy converters and their peripheral components leads to increases in OPEX (repairs) or CAPEX (additional system costs) respectively. Insufficient knowledge of the hostile environments in which ORE systems are deployed therefore affects their CAPEX and OPEX. It is crucial to remove this scientific barrier to de-risk ORE projects, attract investors and allow the sector to develop.
Lack of knowledge of sea states is particularly critical in coastal areas where future commercial farms will be located, because waves undergo significant changes due to their interaction with the bottom. These processes are difficult to simulate, so model errors in these areas are significantly larger than offshore.
The other critical point concerns breaking waves. These can induce loadings several times higher than those caused by non-breaking waves and can severely damage structures at sea. Breaking waves are poorly understood physical process that cannot be accurately predicted.


To characterise coastal sea states and breaking waves using satellite observations.

Scientific content

  • Modelling of sea states in coastal and inshore areas.
  • Development and implementation of innovative methods for extracting very local and quantitative parameters from high resolution satellite imagery.
  • Use of observation analysis to assess modelling results.
