Due to decreasing rotor distances, the planning of new wind turbines often results in certain design values, e.g. turbulence intensities, being exceeded in existing turbines. Sectorial operating restrictions are a potential consequence, which in turn can lead to considerable yield losses. With decades of experience in the field of load calculations for wind turbines and modern simulation technology, we can check whether the bearing capacity of the affected turbines is at risk. Often, measures to protect the affected turbines can be avoided without endangering their stability.
Expertise and experience
With decades of experience in the development of wind turbines – load simulation, design, calculation and highly interdisciplinary work, from the determination of wind potential to mechanical engineering and structural engineering subjects such as the load calculation of wind turbines and modern simulation technology, we can check whether the bearing capacity of the turbines concerned is at risk.
Often, measures to protect these plants can be avoided without endangering their stability. We have a uniform view of possible solutions.
What benefits do we offer?
- Avoidance of operating restrictions: assessment for existing WTGs always possible
- Evaluation of different options and optimisation already during the financing of the windpark
- We work quickly and flexible: we deliver a basis for your decision within 14 days
- Close cooperation with turbulence assessors: we take care of a successful approval process
- No dependency on a specific manufacturer: we evaluate all types of turbines
Our calculation methods
The assessment of site suitability is carried out by comparing certain wind and site parameters with those assumed in the design of the wind turbine.

If individual values are exceeded at the site, further consideration is required. In the case of newly planned plant types that may not yet be type-certified, this is done by the manufacturer of the plant. Evaluating the impact on other plants at the site is often difficult, especially if the manufacturer of the affected plant no longer exists on the market. Based on the past 20 years, we have already been able to convert and use many of these plants in our own models. Furthermore, we are able to create and use our own models in a way that is suitable for testing:
Based on the information available to us, we set up a simulation model of the plant that allows us to evaluate the fatigue reserves of the critical plant components in different load situations. This allows us to investigate for each component whether the stability of the entire plant is actually at risk, or whether exceeding individual design parameters in a particular situation is not problematic.

While the park planning is still in the optimisation process, the project planner has to quickly take many decisions. After we have received all the necessary information, we can, on request, provide a calculation result after a maximum of 14 days.

further Infos
After the preliminary calculation, we can either make further optimizations to increase the overall performance of the turbines in the park or document the result already available in the short term. We attach great importance to comprehensible documentation in order to make the cooperation with turbulence experts and the responsible building authorities as smooth as possible.
