The objective of the FLOATGEN project is to demonstrate the technical and economic feasibility of two different multi-megawatt integrated floating-wind turbine systems in deep waters, never applied before to Mediterranean Sea conditions, in order to extend deep offshore wind resources and demonstrate decrease of costs for electricity generation down to competitive level. The project will also assess, compare and obtain conclusions about performance of suchtwo different combinations of wind turbine and floating structure technologies to get the knowledge to improve performance of the future replication projects of these technologies.To reach such objectives, the project will join a 10 partnership European consortium, industry led by three global wind turbine manufacturers and wind farm operators, GAMESA and ACCIONA WINDPOWER and ACCIONA ENERGIA, in cooperation with the floating systems developers IDEOL and NAVANTIA, the contribution of OLAV OLSEN and STUTTGART UNIVERSITY for structural design, and supported for monitoring, environmental and dissemination activities by FRAUNHOFER-IWES, RSK GROUP and GREENOVATE.
