How to optimise wind turbines design and offshore operations according to sea states?

Our offer

Supporting technology and farm developers to optimise system design and offshore operations based on solid experience in sea state observation and modelling

  • Extreme sea states: estimation of 50-year design sea states for a given site
  • Slamming: definition of slamming loads on an offshore wind turbine
  • Dangerous areas: characterisation of high-amplitude wave areas at the ORE sites
  • Coastal hydrodynamics: 3D wave field reconstruction using stereoscopy

Our references

  • Leading and scientific contribution to the COASTWAVE, DIME and DIMPACT collaborative projects
    • Improvement of the representation of extreme sea states in the Atlantic and Mediterranean
    • Characterisation of coastal sea states and breaking waves using satellite observations
    • Instrumentation and measurement campaigns from offshore observatories: La Jument lighthouse in North Brittany, Unitech Zefyros floating wind turbine off Norway
    • Recommendations for the industrial sector
  • Service provided for a private player in the water sector
    • Measurement campaign and numerical reconstruction of waves to better understand sea states and submersion on the Grande Plage of Biarritz in South West France
