Root cause analysis for wind turbine blades

What is a root cause analysis?

A root cause analysis (RCA) is a systematic process used to identify the underlying causes of a problem or failure. When it comes to wind turbine blade failures, conducting an RCA is crucial for several reasons.

Firstly, wind turbine blade failures can have significant consequences, both in terms of safety and financial impact. Understanding why these failures occur is essential for preventing future incidents and ensuring the continued operation and safety of wind turbines.

An RCA involves digging deep into the factors contributing to the failure. This often requires collecting and analyzing data from various sources, including maintenance records, inspection reports, and operational data. By examining these sources, analysts can identify patterns, trends, and anomalies that may shed light on the root causes of the failures.

Identifying the root causes of wind turbine blade failures is not always straightforward. It may involve looking beyond immediate or surface-level factors and considering broader issues such as design flaws, manufacturing defects, material fatigue, environmental conditions, or human erro

How do engineers start the root case analysis for wind turbine blades?

Upon receiving a request for a root cause analysis, our team of proficient engineers initiates an investigation. This begins with a Request For Information (RFI), where we examine data pertaining to the damaged wind turbine blade. Based on the information our engineers analyze the data to formulate a strategy for the RCA process.

What are the reasons for blade failures?

Wind turbine blade failures can be caused by a multitude of factors, each of which requires careful examination to understand its role in the incident. These factors span a wide range, including environmental influences such as lightning strikes, hailstorms, and sudden changes in wind direction, as well as damages induced by fatigue, human error, or issues related to production quality.Depending on the nature of the failure and the available data, we may proceed solely based on the information provided in the RFI, through remote inspection methods, or by conducting an onsite assessment. Our dedicated blade team is adept at handling each scenario with precision and expertise.

The process of investigation can vary depending on factors such as the nature of the failure and the availability of data. In some cases, it may be possible to proceed solely based on the information provided in a Request for Information (RFI), leveraging remote inspection methods to gather additional data. In other instances, conducting an onsite assessment may be necessary to obtain a more detailed understanding of the situation.

Regardless of the approach taken, our dedicated blade team is equipped with the expertise and experience to handle each scenario with precision. Whether it’s analyzing remote data, conducting onsite inspections, or interpreting complex findings, our team is committed to delivering thorough and insightful assessments to support effective decision-making and problem-solving.


The handover meeting: Ensuring Transparency and Reliability

As part of our dedication to delivering an impartial assessment, we prioritize transparency and reliability in our findings. To ensure a comprehensive understanding of the wind turbine blade failure, we will schedule a handover meeting to discuss all the insights uncovered in the report.
