Tales of Wind #12 - End of warranty inspection

The End of Warranty campaign happens 2 to 5 years after the commissioning date (depending on the O&M provider) and corresponds to the end of the O&M warranty over the wind turbines.

The EoW has 3 main goals :

• Defect or failures identification
• Performance evaluation
• Turbine longevity maximization

During this period, several inspections of major components are performed to evaluate the over all condition and performance, rectifying any defects to ensure that the turbine is handed over to the owner without significant damages.

The end of warranty campaign includes :

• Blade inspection
• LPS check
• Gearbox endoscope inspection
• Vibration analysis
• Oil analysis
• Tower oscillation analysis
• Transformer inspection
• Turbines inspections
