Failure Analysis - Wind Turbines
Utilise Lucideon's decades of expertise in qualifying and evaluating power generation materials to identify the root causes of failure in wind turbine hardware and systems. We perform failure investigations on materials ranging from concrete in the base support system to gearbox and complete generator failure, to support OEMs, owners, operators and insurance companies.
Examples of our work include:
- Turbine blade failure, and all turbine hardware
- Premature bearing failure
- Corrosion and wear-related failure of seal rings in an electric utility generator
- Root cause of deposit build-up on process equipment
- Trip failure in electrical relays
- Root cause analysis of failed rotor lead tabs
- Evaluation of crevice corrosion in generator stator bar brazed joints, leak path and insulation failure investigations
- Total generator failure
- Petrographic analysis of deteriorated concrete support systems.
Research & Development / Quality Control
Analyzing failures during the research and development stage, or during quality control testing, provides fundamental understanding of the material properties required for your specific application and environment, expediting the design phase and supplier quality validations.
Manufacturing - Optimization & Troubleshooting
Determining the root causes for variations in production can be utilized to determine processing windows, create stricter material specifications, and reduce creation of faulty parts.
Failures in Service
Lucideon provides independent failure investigation services that includes materials testing governed by the rigorous quality management system requirements of UKAS, ISO 17025, 10CFR50 Appendix B (nuclear), Nadcap (aerospace & defense), and GE S-400.
We can conduct site visits to examine the failure in its environment and provide advice on appropriate sample collection techniques and photographic documentation of evidence.
