The invention relates to a construction method of an offshore wind power system and the offshore wind power system.The construction method comprises the steps that a gravity type foundation and a floating platform are manufactured, and the gravity type foundation and the floating platform form a whole; towing the whole to a preset position; a plurality of auxiliary sinking cables are connected between the gravity type foundation and the floating platform; the connecting part is removed, primary loading is carried out on the gravity type foundation, so that the gravity type foundation sinks till the gravity type foundation is completely immersed in water, and the auxiliary sinking cable is in a first pre-tensioning state; releasing the auxiliary sinking cable to enable the gravity type foundation to sink to a preset state; before the preset state, a plurality of tension tendons are connected between the gravity type foundation and the floating platform, and in the preset state, the tension tendons are in a second pre-tensioning state; and secondary loading is conducted on the gravity type foundation, so that the gravity type foundation sinks to the seabed. According to the design, the tension tendon does not need to be installed underwater, large equipment does not need to be used for tensioning the tension tendon, and the construction difficulty and the construction cost are reduced.
本公开涉及一种海上风电系统的施工方法和海上风电系统,施工方法包括:制作重力式基础和浮式平台,并使二者形成一个整体;将整体拖航至预设位置;在重力式基础和浮式平台之间连接多个辅助下沉缆;解除连接部并对重力式基础进行一次加载,以使重力式基础下沉至全部浸没于水中,辅助下沉缆处于第一预拉紧状态;释放辅助下沉缆以使重力式基础下沉至预设状态;在预设状态前,在重力式基础和浮式平台之间连接多个张力筋腱,在预设状态时,张力筋腱处于第二预拉紧状态;对重力式基础进行二次加载,以使重力式基础下沉至海床。如此设计,无需水下安装张力筋腱,且无需通过大型设备对对张力筋腱进行拉紧,降低施工难度和施工成本。
