Periodic manual inspections are carried out to collect information on the health status of the main shaft of a wind turbine.

LEO is an autonomous on-board system that allows:

• Service-life extension. Since inspection can be done with an hourly frequency, the minimum utilisation is 96% of the shaft’s useful life.
• Programme several detection and advancement of the cracks, so as the crack progresses the system informs of the need to manage the stock and the scheduling of the stop.
• Automatic inspections without stopping the machine: production optimisation.
• Virtually no variable costs.

• Wind farms
• Models of higher interest: G5X, G8X, Bonus 1300, MadeEA46

• TRL 9
• The system has been validated for field work and is currently installed in a set of 95 wind turbines
