Nabrawind, Tetrace and Comansa set up a joint venture called Navassy for the supply of Nabralift’s self-erecting system
Nabrawind, Tetrace and Comansa have set up a Joint Venture named Navassy which will be responsible for the complete manufacturing and installation process of the Nabralift® self-erecting system that Nabrawind commercializes worldwide. The partners have reached an agreement to provide Navassy with the ne
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 modes are very fast (usually allocated between the 3P and the 6P excitation frequencies band) and torsional deflection on tower
