FW Turbine

The objective of the FW Turbine project is to investigate the operability of floating wind turbines (FWT) in wind and waves and the extreme loads on the structure and mooring lines. Numerical tools and procedures will be developed to calculate the related system responses. While the offshore sea bottom fixed wind turbine (WT) technology can be considered mature, the available locations are limited therefore the technology will migrate to deep water. Above 40 to 50m water depth it probably becomes economically advantageous to use a floater as a support structure for the WT. The FWT concept is still in its infancy.

There are no safe empirical rules based on past experience to support the design of these new concepts, therefore accurate numerical tools are needed in order to design safe and economically viable systems. A numerical model must represent the fully coupled dynamics of the moorings, floater, aeroelastic turbine, generator and control system. Furthermore, several nonlinear contributions require a time domain solution.

Specific objectives of the FT Turbine project are to develop and implement a numerical model to calculate the coupled dynamic response of FWT under the action of wind and waves; use the EDP concept as a case study, characterize the operability of the system at the West coast of Portugal and estimate the extreme motions of the platform and the design loads on the mooring lines and on the structure.
