SITE CLASSIFICATION STUDIES

We routinely provide clients with an assessment of site compliance with IEC or GL wind turbine design criteria, including:

• Extreme wind analysis
• Turbulence intensity estimate at each turbine location
• Extreme temperatures, seismic risk, inflow angles and corrosion class

These predictions are a vital stage in the design and financing of a wind farm project, ensuring that turbine selection is optimised for the prevalent climatic conditions of the site, and further ensuring that climatic risks are understood and properly managed. In complex terrain and forested sites we employ our VENTOS CFD methodology - our site classification service for complex and forested projects. CFD is preferred to linear models such as WAsP in cases of complex flows. VENTOS site classification delivers for each turbine location: wind speed, turbulence intensity, vertical inflow angle, shear across the rotor, veer and indications of flow separation.
