Abstract

As the depths of sites consented for oshore wind increases, the need to develop oating foundations for wind turbines increases, as xed foundations are only economically viable up to approximately 50 m water depth [2]. Key to developing the oating wind turbine industry is the development of accurate numerical models, which can combine the aerodynamic, hydrodynamic, structural exibility and mooring components. Very little oshore data exists, however, in order to validate these numerical models. Floating Power Plant are the developers of a oating, hybrid wind- and wave-energy device. The device uses the pitching wave energy devices, not only to increase and smooth the power output from the platform, but also to take the energy from the waves in a controlled manner, resulting in a stable platform for the wind turbine and a safe harbour for O&M. They are currently developing the nal design for their rst full-scale prototype, the P80, which has a width of 80 m. As part of the development, Floating Power Plant have completed 4 oshore test-phases (totalling over 2 years oshore operation) on a 37 m wide scaled test device, the P37. This paper focuses on the comparison of one of the leading numerical models for oating wind turbines, developed by DTU Wind Energy, to the oshore data from P37. The nu- merical model couples DTU's own aeroelastic code, HAWC2, with a special external system that reads the output les generated directly by the commercial wave analysis software, WAMIT.
