Nabla wind hub\'s preconstructive analysis is the process for which the causes of structural life consumption of wind turbines Security SSCs (Structure, System or Component) are modeled and analyzed per each wind site in order to:

  • Redefine Design Life of turbine components
  • Identify the scope of selective retrofits and maintenance actions

It is based on a simple principle:

  • Turbines are designed against standard and regulated wind conditions which are usually exceed real site wind records.
  • This implies that in spite of wind turbines being designed typically for a 20-year life, in reality their design life can vary from site to site and usually can be extended.

This way, in order to best assess the real effects of each site-specific conditions on the turbine’s life, the boundary conditions are modeled in detail:

  • Site-specific wind conditions
  • Particular operation conditions
  • Turbine morphology and reality of supplied components

The effect of these real conditions on the turbines are merged and evaluated together in a simultaneous and coupled analysis by means of a very detailed Aeroelastic Loads Calculation for which the turbines dynamic performance is simulated according the specific conditions and compared with the design conditions.
