Gearbox vulnerability map - TRL4

A reliability-based inspection and maintenance map for wind turbine gearboxes was developed by a NTNU PhD candidate.

Gearbox vulnerability map

This can have impact on monitoring and inspection of those components which holds higher probability of damage. It can reduce the downtime for fault detection and routine inspection.

Further plan is to promote the method within the wind turbine industry. It has already received positive feedback, but the gearbox manufacturer are those who should be encouraged to produce such maps.
