The invention provides a self-installation type floating fan foundation anchored by a barrel-shaped foundation and a self-installation method of the self-installation type floating fan foundation. Theself-installation type floating fan foundation comprises a floating platform and a barrel-shaped foundation, wherein an offshore wind turbine generator system is fixed to the floating platform, the lower part of the barrel-shaped foundation is embedded into a seabed, the floating platform is connected with the barrel-shaped foundation below through a plurality of tensioned anchoring and mooring cables, the floating platform is arranged in a mode that the sea level is located between the top surface and the bottom surface of the floating platform, and the floating platform is provided with anadjustable ballast tank; the floating platform is provided with an anchor machine and a chain locker, the length of the anchoring and mooring cable can be adjusted, and self-installation of an anchoring and mooring system is achieved. According to the invention, a self-installation construction method can be adopted, the wind turbine generator, the floating platform and the anchoring and mooring system can be installed in one step, a large hoisting ship machine does not need to be dispatched, the construction efficiency is high, and the cost and risk of offshore construction operation are greatly reduced; and under towing installation and service working conditions, the gravity center of the whole structure can be lower than the buoyancy center, good stability is achieved, and the capacityof resisting ocean environment storm flow loads is high.

    本发明提供了一种桶形基础锚固的自安装式漂浮式风机基础及其自安装方法,包括浮式平台和桶形基础,海上风电机组固定于浮式平台,桶形基础的下部嵌入海床,浮式平台通过若干张紧的锚泊缆与下方桶形基础连接,所述浮式平台被设置为海平面处在其顶面和底面之间,浮式平台设置可调压载舱;浮式平台上布置有锚机和锚链舱,可以调节锚泊缆的长度,实现锚泊系统的自安装。本发明可采用自安装施工方法,风电机组、浮式平台和锚泊系统可一步式安装,无需调遣大型吊装船机,且施工效率高,大大降低了海上施工作业的成本和风险;在拖航安装和服役工况下,整体结构的重心均能够低于浮心,具有较好的稳性,抵抗海洋环境风浪流荷载的能力强。
