Resource and site characterisation

IN PARTNERSHIP WITH

The list of partners indicated in this page is progressive and non-exhaustive.

OUR OFFER

Support to farm developers and government offices in quantification of the energy resource and characterisation of sea states at ORE sites

  • Types of resources
    • Waves: precise characterisation of wave breaking, coast and extreme sea states by coupling modeling with in-situ and satellite observations
    • Tidal streams: characterisation of current and associated turbulence by coupling in-situ measurements and numerical modelling
    • Winds: precise characterisation of winds and associated turbulence by coupling modelling and satellite observations
  • Scope
    • Selection of characterisation means (waves, currents, winds)
    • Support for the preparation of measurement campaigns
    • Assistance in the processing and analysis of collected data
    • Selection of models and development of customised codes
    • Preparation of digital studies integrating the parametrisation of models
    • Short-term wind forecast for farm operation (under development)

OUR REFERENCES

Several collaborative R&D projects on the characterisation of offshore wind and tidal sites

  • Tank tests and measurement campaigns from La Jument lighthouse, in the Alderney Race and in the Ria d’Etel (DIME, ELEMENT, HYD2M, PHYSIC and THYMOTE projects)
  • Capturing high-resolution spatial variability of wind fields (CARAVELE project)
  • Improvement of the representation of sea states in the Atlantic and Mediterranean Sea (DIME and DIMPACT projects)
  • Improvement of the knowledge of hydrosedimentary processes and turbulence in the Alderney Race (HYD2M, PHYSIC and THYMOTE projects)
  • Development of the site characterisation module of the DTOcean+ software suite dedicated to the optimisation of tidal and wave farms (DTOCEANPLUS project)
