Current Maintenance Practices for Wind Turbines

Compination of corrective and preventive maintenance\

• Onshore typically serviced twice a year
• Remote Offshore are serviced based on a database of components and their failure rate, variability of the site conditions, etc...
• Offshore Windfarm Operation and Maintenance contributes between 15-30% of the cost of energy, as they usually are less reliable

Reliability Centered Maintenance (RCM)
