Fatigue assessment of WTG secondary steelwork

Blackfish was brought in to address a critical fatigue issue on wind turbine secondary steelwork, with an expedited response a priority for the client. The team delivered practical, analysis-backed concepts under tight timescales.

Blackfish supported a leading wind turbine manufacturer in investigating and resolving a critical fatigue issue affecting secondary steelwork.

The client required an expedited response to a technically sensitive fatigue problem, with limited time available to develop and assess viable solutions.

The team combined practical design experience, collaborative concept development and detailed finite element fatigue analysis to compare options and support the down-selection process.

Blackfish presented practical, analysis-backed concepts to the client and worked effectively alongside consultants and stakeholders to support a rapid engineering response.

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 and provided the client with confidence in the selected design direction.
