Predictive Maintenance Driving Value for the Wind Industry
A predictive or condition-based maintenance strategy lies at the "sweet spot" between preventive and reactive maintenance. By predicting machinery condition and future component failures, maintenance can be performed as and when required, before expensive and potentially catastrophic failures occur. Predictive maintenance delivers optimised O&M cost through minimising maintenance costs whilst minimising consequential costs due to failures. However, there is one critical barrier to employing predictive maintenance today – specific technologies are required to infer the condition of a wind turbine and predict future failures. These technologies are not widely adopted today and those that are – such as basic CMS – tend not to give sufficient lead time before failure to enable a purely predictive maintenance strategy.
