Nabralift decommissioning process: a case comparison to hybrid towers
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 ar
Why torsional stiffness of Jacket-type structures has a low influence in WTG dynamics
Wind turbine towers are traditionally based on steel tubes of large diameter and thickness. This configuration provides an excellent torsional stiffness, and therefore torsional mo
The Challenges of Designing a Modular Blade
(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 Ene
Patent as technological indicator in renewable energy
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 comp
Breaking the logistic barriers in XXL blades industy
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
WTG dynamics in soft & stiff towers beyond 160m hub height
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,
