The main research content of this paper is to ensure the stability of composite bucket foundation during the construction.Method Through the transport field experiment of one-step transport installation ship, the real-time monitoring of tower drum and blade lifting and towing process during the construction of Xiangshui 25# wind turbine in Jiangsu was carried out.Result The results show that the dip angle of composite bucket foundation was smaller in the process of tower drum and blade lifting; during towing, the interaction force between drums, the roll angle and the height of liquid seal in tubes all met the requirements.Conclusion The results show that the composite bucket foundation had good stability during the tower drum and blade lifting process. In the towing process, the transport ship was closely fitted with the composite bucket foundation, which can ensure the stability of the whole structure in the transportation process. Moreover, the composite bucket foundation can provide stable buoyancy in the process of towing.
