Today, there are more than 34.000 onshore wind turbines which are 15 years or older, with a total capacity of 36 GW (WindEurope, 2020). Among those, 9 GW belong to turbines that are 20 to 24 years old and 1…
Wind turbine towers are traditionally based on steel tubes of large diameter and thickness. This configuration provides an excellent torsional stiffness, and therefore torsional modes are very fast (usually allocated between the 3P and the 6P excitation frequencies band) and…
(This is an article released in Indian Wind Power Magazine.) Modular blades are not something new in the wind industry. More than a decade ago, some companies such as Gamesa or Enercon released their own split blades. However, at that…
When a global, capitalist and changing world, patents are the only proven and reliable technological bulwark. The already patented technologies have passed a broad filter when compared to State of the Art (everything that previously has been published worldwide) that…
MODULAR BLADES MARKET The growth of the wind market, together with the low availability of sites with optimal wind conditions, is creating a rapid increase in the size of turbines and therefore the diameter of some rotors that work at…
The latest generation of wind turbines announced by the leading OEMs will shift wind turbines to rotor diameters of 150m and blade tip heights above 240m. As a consequence of this, the transport and installation ofmassive blades and towers becomes…
Nabrawind Technologies was founded in 2015 by veterans of the renewable industry with decades of experience in development of innovative technologies. The team currently consists of 20 engineers, who have spent the last 20 years working with the major global…
