Dynamic Responses of a Scaled Tension Leg Platform, Wind Turbine Support Structure in a Wave Tank

摘要

Understanding the dynamic behaviour of offshore wind and wave energy devices is extremely important in relation to the maintenance and management of these marine assets. Since experimentation in sea may often be difficult, expensive or unnecessary at a conceptual or at pre-commercial stage, scaled experimentation in wave tanks can be central to the understanding and assessment of their dynamic responses. This paper presents scaled dynamic testing in a wave tank of a tension leg platform for supporting a wind turbine for different regular wave conditions and sea states characterised by the Bretschneider spectra. The dynamic response of the device was monitored at different locations on the device using load cells and with a camera based motion recognition system.
