Nabrawind presents the benefits of stiff towers in the 6th International Conference of Wind Turbine Towers
Nabrawind Technologies has been invited for the second year running to participate in the International Conference of Wind Turbine Towers, celebrated in Bremen from 29th to 31st of August. Participants in this conference included experts from some of the major wind energy companies such as Vestas, Siemens-Gamesa, Goldwind, Envision, General Electric and Nordex-Acciona Windpower.
Cristina Garcia, senior engineer from Nabrawind and expert in load calculations, presented her investigation regarding the influence of tower stiffness on loads induced in the tower itself and the foundation. This study concludes that towers with higher rigidity (soft-stiff, like Nabralift self erecting tower), compared to more flexible metallic alternatives (soft-soft), reduce the loads in the structure, specially during in emergency stop events of the wind turbine generator allowing cost reduction in the tower and the foundation. Presentation file can be downloaded in our Media Centre.
Nabrawind was able to carry out this investigation by drawing on team knowledge, with the capability to simulate the performance and operation of wind turbine generators as well as calculate and certify loads, simplifying the engineering process to be developed by its clients.
Ion Arocena, chief of the Nabralift program, chaired the “Transport and Installation” round table, where future solutions for the logistics and installation of large towers were discussed. In this round table, it was evident that the sector is expecting to see new technical solutions to overcome the large challenges that the logistics and the installation of towers and blades of the new generation of 3.5-4.5MW wind turbines will bring.
In conclusion, during this congress the most important experts in the sector have confirmed that the market continues to seek solutions for low cost towers and easier installation at new hub heights for the new wind turbine generators that are currently under development.
