Abstract:To investigate the impact of different wind, wave, and current loads on the motion stability performance of a new type of floating wind turbine during integrated towing operations, this study is based on numerical simulations using the AQWA software. The simulations systematically model the floating wind turbine's motion response under varying wind loads (wind speeds of Vwind = 0, 10.7, 21.4 m/s), wave loads (significant wave heights of Hs = 0, 1.5, 2.5, 3.5, 4.5, 5.5 m), and current loads (current speeds of Vcurrent = 0, 0.25, 0.5 m/s). The primary performance indicators include the time history curves and statistical characteristics of heave, roll, pitch, and towing cable forces during the towing process.The results indicate that under static water conditions, wind load significantly affects the towing resistance of the floating wind turbine; as wind speed increases, the towing cable force increases, leading to greater average roll and pitch angles. Under the same wind and current loads, as the significant wave height increases, the towing resistance of the floating wind turbine also increases, and the fluctuations in roll and pitch angles during towing become more pronounced. When the significant wave height reaches 5.5 m, the maximum roll angle is 1.883°, and the maximum pitch angle is 5.814°. In the same wind and wave load environments, the towing resistance of the floating wind turbine increases with the rise in current speed, while the pitch angle remains within ±2.0° fluctuations. The findings of this study can provide references for addressing the safety issues associated with the towing transportation of floating wind turbines and improve the selection of towing departure conditions in engineering practice.
