Wind turbine lifetime extension – everything from a single source

The design lifetime of a wind turbine does not have to be its final word. With a thorough assessment and review for continued operation (BPW), the operating life of your turbine or wind farm can be extended in a targeted and safe manner – based on currently applicable standards and with a partner who covers the entire process.

What sets us apart

While most providers specialise in individual sub-areas, we offer the complete BPW process in-house – from turbulence analysis through computational assessment to on-site inspection. No interface losses, no external dependencies – everything from a single source.

Turbulence analysis – the foundation of every assessment

A reliable BPW stands or falls with the quality of the turbulence report. We produce this ourselves – site-specific and simulation-ready. This means that real site conditions flow directly and consistently into our load calculations, without any translation losses through third-party providers.

Analytical part – computational remaining service life

Based on our own turbulence report, we determine component by component when load-bearing parts reach the limits of their service life. We compare the actual site loads that have occurred with the original design loads specified by the manufacturer.

  • Actual operating hours, downtime and yield data
  • Site-specific turbulence from our own report
  • Simulation of future loads under continued operation conditions

This allows the remaining life reserve of each component to be determined precisely – and the safe continued operation period to be clearly defined.

Practical part – on-site inspection

The practical part comprises a structured on-site inspection of all safety-relevant components. The results are fully integrated into the overall assessment – since analytics and inspection come from a single source with us, a consistent, non-contradictory overall picture emerges.

Result – expert report and certificate

All three components culminate in an expert opinion with a certificate on the determined remaining life reserve. The verifiable analytical report serves as a structural stability assessment for submission to the responsible building authority.
