How do deal with new designs & upgrades


       {A sentence or two about the new design & upgrade concepts}



  • RomaxWind model of the rotor and main bearing closely simulates bearing loads and is tuned to match field failure data and contact pattern
  • The model can then be used to simulate performance of design upgrades and retrofits

OPEX forecast : Lessons learned



  • same regions
  • same operating conditions
  • two manufacturers 2MW WTG
  • two OEM services teams




  • same site
  • same turbine
  • different gearbox manufacturer




  • same turbine
  • different site-operating conditions (turbine, capacity factor, wind shear)
