The technology, developed and patented by Esteyco, is based on the use of a self-transporting GBS and a self-lifting precast concrete tower, suitable for depths in the 20-55m range. The main advantage of this technology is that it does not require the very large, scarce and expensive auxiliary means for transport or erection that are needed for alternative solutions, originating significant savings and increasing the scalability of the solution. The ELISA project covers the design, manufacturing and installation of the GBS in deep waters. The manufacturing will take place at the Arinaga Harbour, where the drydock has been built in order to provide the adequate space and conditions for the foundation to be manufactured. Afterwards, the foundation and the bottom part of the shaft will be loaded out in order to install the auxiliary floating system and to perform the ballasting tests prior to the pre-installation of the rest of the tower and turbine on the foundation. The complete structure is to be installed at the PLOCAN area, at 30m depth, in the North-East waters of Gran Canaria.
