Abstract

Floating offshore wind turbines present several advantages over land-based and bottom-fixed offshore wind turbines, but they are also exposed to strong environmental loads, especially wind and waves, which generate vibrations in the structure and compromise their efficiency and useful life. In this paper, a simplified theoretical model of a barge-type 5MW floating offshore wind turbine is developed and validated with reference software FAST, and used to study the effects of structural control. A tuned mass damper (TMD) is tuned using genetic algorithms for free decay different pitch angles of the platform, which could simulate different heights of waves impacting the turbine, with the goal of reducing the fore-aft tower top displacement. The proposed structural control improves the dynamic response of the system, with a vibration suppression rate of 34.9%.
