As part of its ongoing commitment to innovation, research and development, TYPSA Group has been consolidating its position in recent years as an authority in the design of gravity base foundations for offshore wind power.
GRAVI3 technology is one of the results of this commitment. This innovative steel and concrete hybrid structure for wind farms at intermediate depths, between 35 and 60 metres, will significantly reduce the levelized cost of electricity (LCOE). Three concrete caissons are built on a floating dock, the steel structure and the turbine are installed on top and they are then towed to their final location. Once in position they are sunk to a prepared bedding layer on the seabed, using water as ballast.
The European Commission has selected a proposal made by TYPSA, as the owner of the patent, and the Portuguese group EDP and other partners, to carry out a demonstration project of this technology, within the framework of the Horizon 2020 programme. The project will include design and engineering, construction, assembly, transport, installation and demonstration of a full-scale structure, equipped with a wind turbine, installed in an authorised place and connected to the grid.
This pilot project will serve to develop the technology further to improve the design and carry out an in-depth assessment of the technology’s future scalability, industrial processes, competitiveness and prospects for profitability.
