In November 2015 EDP was granted European funding to develop new technology for offshore wind power. DEMOGRAVI3 is a project that aims to develop an innovative gravity based foundation for offshore wind turbines and will be funded by the European Commission’s Horizon 2020 programme.
The consortium developing this new project will be coordinated by EDP, through EDPR. DEMOGRAVI3 will test a wind turbine with an innovative gravitational foundation made of concrete and steel. The project will last for four years, including the installation of a wind turbine taking advantage of the underwater cable connecting the WindFloat turbine to a substation on land.
Unlike the solution based on a floating platform successfully tested with Windfloat, DEMOGRAVI3 will be installed on the seabed, although it will already be assembled and floated to the mooring place. The whole structure of the turbine and its constituent elements will be assembled on shore and then transported. The main innovation of this structure thus avoids the necessity for heavy lift vessels to anchor and assemble all the turbine components in an offshore environment.
The project includes other technological partners such as: TYPSA, ASM Energia, Univ. Politécnica de Madrid, WavEC, Acciona Infraestructuras, Fraunhofer Gesellschaft IWES, Gavin & Doherty Geo Solutions and Global Maritime AS.
