Forensic Analysis of Failures in Wind Turbine Components
Forensic Engineering
Wind Turbine Failure Analysis
Forensic engineering applied to wind turbines involves the structured technical investigation of structural, mechanical, or functional failures, aiming to determine their root cause and assess their operational and economic impact. Our approach combines advanced Root Cause Analysis (RCA) methodologies, structural modeling, specialized inspections, and review of operational history to accurately reconstruct the failure sequence and its underlying mechanisms.
Based on verifiable technical evidence, we provide robust conclusions that support claims processes, assignment of responsibilities, mitigation plans, structural redesigns, and Aging Management Plans (AMPs). Beyond identifying the root cause of failures, our work focuses on reducing recurrence, optimizing asset reliability, and preserving performance over time.
Integrated within the overall O&M strategy, forensic analysis becomes a key tool for asset managers and owners seeking to minimize technical uncertainty, strengthen decision traceability, and protect asset value.

Structured Failure Analysis Capabilities for Wind Turbines:
Structured Technical Investigation
Detailed reconstruction of the failure sequence through specialized inspections, non-destructive testing (NDT), document analysis, and review of operational history, with full traceability of technical evidence.
Evidence-Based Root Cause Analysis (RCA)
Application of advanced RCA methodologies combined with structural modeling and correlation with operational data to identify failure mechanisms, contributing factors, and deviations from design or nominal conditions.
Support in Technical Claims and Disputes
Preparation of independent expert reports supporting OEM warranty processes, contractual claims, or technical litigation, providing robust and defensible conclusions.
Quantification of Technical and Economic Impact
Assessment of the failure’s effect on structural integrity, remaining life, availability, and future costs, including mitigation, repair, or redesign scenarios.
Recurrence Mitigation and Prevention
Definition of corrective and preventive actions, structural reinforcements, and Aging Management Plans (AMPs) aimed at improving reliability and preserving asset value.
Claims Processes for Wind Assets
At Nabla, we support asset managers, owners, and operators throughout the entire technical and contractual claims process, providing independent support for resolving issues arising from component failures, performance deviations, or contractual non-compliance. Our approach integrates forensic engineering, Root Cause Analysis (RCA), evaluation of technical evidence, and document review to ensure that each claim is grounded in objective and verifiable foundations.
Each process is carried out through a rigorous analysis of the failure’s root cause, its operational impact, and contractual implications, defining a solid technical strategy aligned with the project’s legal and financial framework.
Key benefits include:
- Structured technical and documentation support for claims, negotiations, and arbitrations.
- Objective quantification of the technical and economic impact of the incident.
- Definition of mitigation, repair, or redesign strategies to limit future risks.
- Optimization of contractual position and reduction of financial exposure.
This approach ensures that claims are not limited to resolving individual conflicts, but are integrated into a strategic asset lifecycle management process, strengthening technical traceability, operational reliability, and the preservation of asset value.
Advanced Engineering
Applied to Claims Processes
Our approach to technical claims relies on advanced engineering tools and our extensive experience in Root Cause Analysis (RCA) for wind turbines. We combine structural modeling, load analysis, and operational knowledge to technically support each claim with a solid and defensible foundation.
Technical Reconstruction of the Event
Structural modeling and load analysis to recreate the real conditions that led to the failure, integrating SCADA data, operational history, and type-site characteristics. This process enables demonstration of the technical sequence of the event and its consistency (or deviation) with the original design.
Advanced Root Cause Analysis (RCA)
Application of structured RCA methodologies combined with physical-structural analysis to identify damage mechanisms, contributing factors, and technical responsibilities. Our approach enables differentiation between expected wear, design or manufacturing defects, and operational or maintenance issues.
Structural and Economic Impact Quantification
Assessment of the failure’s effect on structural integrity, remaining life, and future availability, including repair, reinforcement, or replacement scenarios. This analysis translates technical damage into objective economic metrics for negotiation or arbitration.
Technical Support for Contractual Strategy
Preparation of structured technical reports aligned with the contractual framework (EPC, O&M, OEM warranties, PPA), providing defensible arguments for claims, negotiations, or dispute resolution.
Independent technical analysis based on forensic engineering, structural modeling, and document review provides a verifiable evidence base to support claims. This approach facilitates the resolution of technical and contractual disputes, clarifies responsibilities, and supports decisions aimed at safeguarding asset value.
