Özet:
With the realization of the potential of wind energy in deep water, interest in floating platforms is increasing. In this study, the hydrodynamic behavior of offshore floating wind turbines was examined experimentally and numerically. This study is the first small-scale experimental model study on floating offshore wind turbines in Turkey. Experiments were carried out in the wave channel with dimensions of 40.0m×1.0m×1.4m in the hydraulic laboratory of the IZTECH Civil Engineering Department. A new floating platform developed through a Tübitak project was tested under various wave and extreme wind conditions. Responses of the turbine and platform system and the tensions in the mooring chains were measured. Free decay, hydrostatic, quasi-static, and regular and irregular wave and wind tests were performed. Results were compared with the results of the existing spar platform model tests under the same test conditions. It was concluded that the innovative platform was more stable than the spar platform, especially in terms of rotation in the y direction, which is critical for stable energy generation and fatigue loads. The new platform, together with the turbine and the mooring lines, was also modeled numerically using a potential theory-based program. Experimental free decay tests were used to calibrate the numerical model. After calibration, regular and irregular wave test results were used for the validation. Agreement between the numerical and experimental model studies showed that the numerical model of the innovative floating platform was verified and could be used to develop and examine the platform on a prototype scale.
