Esteyco has developed and patented the ELISA technology, represented by the ELICAN prototype. It is the world’s first installed without large ships or marine cranes currently used for this purpose. This currently represents savings of around 30%, if compared to other technologies, in the following scope: foundation+tower construction and foundation+tower+WTG installation and pre-commissioning. Whilst there are no differences with other solutions in respect to energy yield, operating cost are also significantly reduced. As it is further explained in the followed video.
