Wind turbine and Foundation coupling specialists

Wind turbine and offshore foundation are complex systems. They are loaded for more than 20 years with external components (turbulent wind, irregular sea states). The response of each component impacts the other ones (foundation motions, wind turbine cyclic loadings) and shall be assessed with care.

Analysing and optimising the behaviour of such complex coupled systems requires setting up full numerical models. This is WINDGLAZ ‘s field of expertise.

Environmental conditions

Collection, interpretation and justification of environmental conditions for a specific site are the starting points for any offshore wind project. We have been responsible of the specification and assessment of this data for many offshore wind projects. WINDGLAZ assists you in the analysis and definition of environmental conditions, relating to certification requirements.

Type of studies

  • Oceano meteo conditions processing
  • Loading situation definition
  • Environmental condition representativity assessment
  • Turbulent and deterministic wind modelling
  • Cyclonic and deterministic wind modelling
  • Swell impact loading calculation
  • Justification and documentation with certification body

Numerical models calibration and validation

Numerical models for offshore wind turbine analysis cover several of our core skills : aerodynamics, hydrodynamics, structure behavior and soil interaction. With its multidisciplinary team, WINDGLAZ assists you in the setup, calibration and validation of these models.

Type of studies

  • Equivalent turbine model setup
  • Hydrodynamic model setup and calibration
  • Structural model setup and calibration
  • Modal analysis
  • Hydrodynamic data base calculation (diffraction radiation)
  • Hydrodynamic and soil damping calculation
  • Tank test specification and follow up
  • Justification and documentation with certification body

Calculation loop, sensitivities and optimisation

Analysing an offshore wind system requires a large number of simulations due to the important impact of fatigue loadings and extreme events.
With a strong experience and performant computation capabilities, WINDGLAZ assists you in the system loads calculation and assessment.

Type of studies

  • Coupled calculation methodology definition and documentation
  • Aerodynamic loadings calculation and analysis
  • Hydrodynamic loadings calculation and analysis
  • Coupled loadings calculation (turbine – Foundation – Soil)
  • Clustering study
  • Specific Sensitivity study
  • Optimisation loop
  • Fatigue and Extreme loads postprocessing following standards and norms
  • Load reports
