5. • A wind turbine manufacturer started to use the
OilWear Sensor in 2015 at their repair shop located
in Spain
• Using OilWear, they identified particles in a repaired
1,5 MW gearbox.
• The sensor allowed them to identify different kind
of problems in the gearbox:
• Fatigue
• Sliding wear
• External contamination with fiber.
• This early diagnosis avoided a fatal failure in the
gearbox, a major repair and a warranty claim.
Root Cause analysis
Success Case
The Customer estimated the cost saving about
≈100.000 €.
As reference, the renting for two cranes required during the installation
maneuver is about 20.000 €.

6. • Gearbox are tested to warrant high quality levels
• Based on the OEM standards these gearboxes are
subjected to endurance tests
• Using OilWear, OEM and Wind turbines operators
may:
• Identify the level of wear in the critical
components
• Link the impact of operational modess in
Gearbox Condition
• Optimize the control and operation in the
Wind Turbines
• Make decisions based on early diagnose of
potential failure.

8. Atten2 provides a solution oriented to reduce the operational risk, through the On-line
monitoring of the level of wear that takes place in the machine,
Risk Reduction
Certain kind of inspections such as the bearing, gearbox and shaft, may be accomplished when the
machine condition needs it, instead a calendar base strategy. As added value, the customer will
receive an on-line report about his machine condition and how the operation affects its reliability.
Productivity
Implementing this Technology may have an impact in cost reduction by:
• Reducing oil changes,
• Reducing important failures in gearboxes and bearings
• Reducing costs in down tower maintenance
• Optimizing maintenance planning and resources
Cost Out
This technology together with operational data, may provide an in-depth information of the
machine condition and may add a new perspective about maintenance policies
