Root Cause Analysis for wind turbine blades
Independent insight that strengthens underwriting and claims decisions
Trusted technical clarity for the insurance market
Wind turbine blades are some of the most highly loaded structures in the energy sector, and when an incident occurs insurers need clarity they can rely on. With complex interactions between design, manufacturing and operational loading, understanding why a blade has failed is rarely straightforward. This insight is essential for accurate underwriting, clear liability assessment and confident claims decisions.
Our Root Cause Analysis (RCA) service provides insurers, brokers and risk managers with independent evidence-based technical insight that supports fair liability determination. Supported by one of the industry’s most extensive blade damage databases and long-standing structural expertise, we deliver a clear explanation of what happened, why it occurred and how it affects long-term performance.
Because we are fully independent from OEMs and certification bodies, our conclusions are unbiased and evidence based. This gives insurers the confidence to make fair and informed decisions throughout the policy lifecycle from underwriting and risk evaluation to negotiations and repair validation.

Turning blade failure into a winning claim
Bladena was brought in after a disputed blade‑break claim. Our independent RCA overturned the original narrative by proving the real failure cause: sound manufacturing, but operator pushed the blades beyond design limits.
Through data‑driven analysis and precise technical refutation, we armed the insurer with a defensible arbitration position, demonstrating the power of expert RCA in high‑stakes blade‑failure disputes.
Bladena is part of RES, the world’s largest independent renewable energy company. We continue to operate independently but benefit from RES’ insight as a major developer and operator.
This unique connection helps us stay focused on what matters most in the field, including reliability, performance, and lifetime value.
