Tools and methods for site characterisation

The objective is to have measurement, characterisation and simulation methods to provide an accurate description of the physical environment (wind, wave, current, temperature) and the seabed of sites suitable for the installation of MRE farms.

The main challenge is to acquire a better understanding and mastering of the marine environment in order to better select the areas where the farms are to be located, to optimise the overall performance of the machines by improving understanding of interactions between ORE technologies and the marine environment, but also by providing reliable information for a better consideration of environmental impacts.

Meteocean

  • Spatialisation of observations
  • Measurement and modeling of extreme events
  • Characterisation of the high frequency dynamics of resources
  • Improved wind-wave-current coupling

Marine geology and geophysics

  • Characterisation of sediment dynamics
  • Ground characterisation through geophysic
  • Seismic risk prevention / slope stability, human activities
