The invention discloses a deepwater ocean platform pile foundation installation method which comprises the steps that a plurality of buoyancy cabins are arranged on a pile foundation and used for providing buoyancy for the pile foundation to freely float on the water surface, then the buoyancy cabins at the bottom are opened step by step, water is injected into the buoyancy cabins, the pile foundation is centralized under the assistance of a floating crane, and then the pile foundation is lowered to a designated position, and finally fixed by a pile hammer. The deepwater pile foundation can besafely and efficiently installed, dependence on a large hoisting ship is reduced, underwater righting of the pile foundation is achieved by means of buoyancy, the super-large and super-long pile foundation righting problem is solved, the operability is high, the construction cost and the operation risk are greatly reduced, and the construction efficiency and reliability are improved.
本发明公开了一种深水海洋平台的桩基安装方法,通过在桩基上设置若干浮力舱,用来提供桩基在水面上自由漂浮的浮力,然后通过逐步打开底部的浮力舱,使浮力舱内注水,再加上浮吊的协助作用,将桩基扶正,然后将桩基下放至指定位置,最终通过打桩锤固定。本发明可以实现深水桩基安全、高效安装,不仅降低了对大型起重船舶的依赖,而且借助浮力实现了桩基的水中扶正,解决了超大、超长的桩基扶正难题,可操作性高,大大降低了施工成本和作业风险,提高了施工效率和可靠性。
