Uptower Inspection of Winergy PEAB 4425.4 Gearbox

Comprehensive uptower boroscopy inspection of a Winergy PEAB 4425.4 gearbox for Vestas V100 to assess internal condition without dismantling.

We performed a specialized uptower boroscopy inspection on a Winergy PEAB 4425.4 gearbox installed in a Vestas V100 wind turbine. With a power output of 2 MW, ensuring the operational integrity of this unit is crucial for maximizing energy production in the Czech region.

Our field service team executed a precise visual examination of the internal components—including high-speed bearings and planetary gears—directly within the nacelle. This non-intrusive diagnostic approach allows for the early detection of wear patterns and potential issues without the costly need for crane mobilization or gearbox removal. By providing a detailed condition report, we enabled the operator to plan maintenance proactively, minimizing downtime and extending the asset's lifecycle.
