The invention provides a floating type offshore wind power foundation and an installation method thereof. The foundation comprises a floating type foundation body, one end of the mooring system is fixedly connected with the floating type foundation, and the other end of the mooring system is fixed to the seabed; the ballasting system comprises a suspension assembly and a ballasting caisson, the ballasting caisson is suspended below the floating type foundation through the suspension assembly, the ballasting caisson is hollow, a plurality of partition plates are arranged in the ballasting caisson from top to bottom, the ballasting caisson is divided into a plurality of layers by the partition plates, and a valve is arranged on each layer of the ballasting caisson. The gravity center of the floating type foundation is reduced by suspending the ballast caisson, the oscillation motion damping of the floating type foundation is increased, and the stability is good, so that the overall size can be reduced, the manufacturing cost is reduced, large hoisting equipment is not needed during installation, the installation cost can be saved, the time consumption of offshore installation operation is shortened, and the total engineering cost is reduced.

    本发明提供了一种漂浮式海上风电基础及其安装方法,其中基础包括:漂浮式基础;系泊系统,系泊系统一端与漂浮式基础固定连接,另一端用于固定在海底;压载系统,压载系统包括悬挂组件和压载沉箱,压载沉箱通过悬挂组件悬挂在漂浮式基础的下方,压载沉箱内部中空,压载沉箱内由上至下设置有若干分隔板,分隔板将压载沉箱分隔为若干层,每层压载沉箱上均设有阀门。本发明通过悬吊压载沉箱以降低漂浮式基础重心,增加漂浮式基础的摇荡运动阻尼,稳定性好,从而可减少整体尺寸,减少制造费用,并且在安装时无需大型起重设备配合,能够节省安装费以及缩短海上安装作业耗时,降低工程总成本。
