Fatigue assessment of WTG secondary steelwork

Blackfish supported a leading wind turbine manufacturer in assessing a fatigue-related concern affecting secondary steelwork. Using finite element fatigue analysis alongside practical engineering experience, the team provided evidence to support the selected design direction, reducing technical risk and supporting a rapid engineering response.

Blackfish supported a leading wind turbine manufacturer in assessing a fatigue-related concern affecting secondary steelwork.

Fatigue assessment provides evidence to support engineering decisions where cyclic loading, structural durability and long-term operational performance are critical to project success.

Using finite element fatigue analysis alongside practical engineering experience, Blackfish evaluated multiple design concepts, supporting option development, comparison and down-selection under accelerated project timescales.

The resulting assessment provided evidence to support the selected design direction, reducing technical risk and increasing confidence in implementation.

Challenge

A leading wind turbine manufacturer had identified a fatigue-related concern within secondary steelwork and required a rapid engineering assessment. Any proposed solution needed to address the fatigue issue while remaining practical to implement within project timescales.

Approach

The Blackfish team combined practical design experience with detailed finite element fatigue analysis to evaluate potential solutions. Multiple concepts were developed and assessed collaboratively, allowing options to be compared and refined before supporting the down-selection process.

Outcome

Blackfish delivered practical, analysis-backed solutions that addressed the fatigue concern while remaining feasible to implement within project constraints. The work supported a rapid engineering response, reduced technical risk and provided evidence to support the selected design direction.
