End of Warranty (EOW) Approaching

End of Warranty (EOW) approaching?

Cut the guess work out of EOW gearbox inspections. Use Poseidon Wear Debris Monitoring to implement a data-driven approach to save time and money while ensuring you catch every issue.

Gearbox borescope inspections are exceedingly difficult. Even the most skilled technicians will end up missing damage because of difficulty accessing certain gear/bearing positions and time constraints. 100% borescope sweeps for EOW are inefficient and ineffective. Wear debris data can provide an extremely high degree of confidence such that owners can make the decision to forego inspection on most gearboxes and focus inspection efforts only on gearboxes generating high amounts of debris.

Data-Driven Approach

Wear debris monitoring provides incredible insight into the overall health of the gearbox. Comparative analysis across a site will identify outlying gearboxes that are producing more debris. Inspection efforts should be focused on these gearboxes first to capitalize on inspection man-hours. Using this data saves hundreds of man-hours from the process as there is no need to inspect gearboxes that aren’t generating metal.

Maximizing Warranty Coverage

Higher debris generating gearboxes are more likely to contain visually identifiable damage that can result in warranty claims. By proactively identifying and addressing gearbox issues through wear debris monitoring, wind farm operators can ensure that any necessary repairs or replacements are carried out while the turbines are still under warranty. This helps in maximizing the cover- age provided by the manufacturer’s warranty, saving significant costs that would otherwise be borne by the wind farm owner post-warranty.

Cost Avoidance and ROI

Utilizing the data-driven approach that Wear Debris Monitoring enables will ensure a higher likeli- hood of identifying issues while the equipment is still under warranty. Across a given wind farm, if Poseidon wear debris monitoring identifies a single gearbox issue that would otherwise be missed by traditional EOW inspections and vibration CMS, the cost avoidance of that gearbox replacement under warranty more than justifies the cost of implementing Poseidon equipment on every turbine. This ROI scenario is nearly immediate, and the wind farm will benefit from this technology for the remainder of its lifecycle.

Long-Term Asset Management

Beyond the warranty period Wear Debris monitoring can lead to improved overall reliability of a wind project. Through early fault detection, damage progression tracking, and utilization as a life extension gauge, Owners will be able to consolidate gearbox repairs and replacements during periods of fare-weather to achieve economies of scale through on repair costs as well as gearbox and gear/bearing purchases.


Only turbines 1 through 7 showed signs of abnormal wear through online oil debris monitoring, so the customer only performed borescope inspection on these gearboxes, as the chart below shows. Turbines 8 through 15 did not have significant wear detected, meaning there would be nothing for the inspection to find.

Poseidon Systems Wear Debris data can contribute to a comprehensive asset management strategy. This data-driven approach enables condition-based machine maintenance rather than time based. This results in better decision- making for maintenance, component replacement, and potential upgrades, ensuring the long-term profitability and sustainability of the wind farm.
