Root Cause Analysis & Failure Investigation
Independent investigation of failures, defects and recurring technical issues across wind turbines and renewable energy assets.
Evoegy combines engineering review, operational data, inspection evidence and practical asset experience to identify failure mechanisms, contributing factors and root causes. Our investigations are structured to support clear technical decisions, remediation and risk reduction.
What we support
- wind turbine component failures and recurring defects
- main bearing, gearbox and drivetrain investigations
- blade damage, lightning and structural defects
- generator, transformer and electrical-system failures
- pitch, yaw, braking and auxiliary-system issues
- construction and installation non-conformities
- lubrication, wear and material-related failures
- fleet-wide and common-mode defect assessment
Practical engineering review
Failure investigation requires more than identifying the damaged component.
Evoegy reviews the available technical evidence, including operational and SCADA data, maintenance history, inspection findings, drawings, specifications, OEM information, laboratory results and previous interventions. Potential failure mechanisms are assessed against the evidence to distinguish between the immediate failure, contributing conditions and the underlying root cause. Where further evidence is required, we can define and coordinate targeted inspections, testing or specialist analysis.
Independent technical advice
Our role is to provide an independent technical position that supports the next decision.
This may include defining immediate containment actions, assessing fleet exposure, developing inspection or monitoring programmes, reviewing repair strategies, evaluating OEM proposals or supporting broader remediation. Evoegy can remain involved through implementation and close-out, providing technical oversight of corrective actions and helping confirm that the identified risks have been properly addressed.
