WP 4 - Offshore Support Structures



To achieve innovative jacket designs in the 10MW class in terms of enabling at least 20% cost reduction compared to current designs by innovations on the components level, to assess risks and possibilities and to preliminary design an innovative 20 MW substructure and to validate numerical models of non-linear floater behaviour in wave tank tests and deliver first floater concept designs to speed up their time to market.

Second scaled wave tank tests of a semisubmersible floating 10MW wind turbine

After the first model tests of a floating wind turbine in a combined wind-wave basin in September 2014, INNWIND.EU-Task 4.2 has again tested a semi-submersible floating platform for the 10MW INNWIND wind turbine in the facility of Ecole Centrale de Nantes, LHEEA. A new Hardware-In-The-Loop approach was developed by partner CENER (Centro Nacional de Energías Renovables) and additional tests with the rotor built by Politecnico di Milano were performed on the platform model built by the University of Stuttgart. The test results are now being analyzed by more than six European research institutes in order to improve the software simulating the complex dynamic system behavior of floating wind turbines. The task aims at advancing the new floating wind power technology by integrated simulation and design methods aiming at large rotor systems

First Series of Wave-Tank Tests of a Floating Wind Turbine Model in Task 4.2 successfully completed

The first test of a model of the INNWIND.EU 10MW wind turbine on a floating foundation was successfully tested during September 22 until October 3, 2014 at the “LHEEA - Research Laboratory in Hydrodynamics, Energetics and Atmospheric Environment“ in Nantes/France by the INNWIND.EU partners USTUTT, CENER, POLIMI, DTU, DHI, NTUA and DNVGL. After assembling the platform model, built at the University of Stuttgart, with the scaled wind turbine model (1:60), built at Politecnico di Milano, combined wind-and-wave tests under realistic operational and extreme conditions were conducted. Later this month the tests will be continued with a ducted fan at the tower top, built by CENER, which imitates the aerodynamic thrust forces.
