The invention relates to an installation method of an overwater pressure rising station foundation, the overwater pressure rising station foundation comprises a jacket, a buoyancy tank is bound on the jacket, the installation method comprises the following steps: fixing the overwater pressure rising station foundation on a semi-submerged ship, and enabling the jacket to be vertically arranged; controlling the semi-submerged ship to submerge to a preset depth, wherein the preset depth is a depth capable of enabling the buoyancy of water to the jacket to be greater than or equal to the maximum hoisting weight of the jacket and the floating crane ship; a hoisting device of the floating crane ship is connected with a jacket of the underwater pressure rising station foundation; the jacket and the semi-submerged ship are disconnected; and the floating crane ship is controlled to hoist the jacket to the mounting position of the underwater pressure rising station. According to the mounting method, the jacket can be lifted by means of buoyancy of water, the requirement for the maximum lifting weight of the floating crane ship is lowered, the floating crane ship can meet the requirement for vertical lifting, the jacket is lifted to the mounting position of the water pressure rising station in a vertical lifting mode, and the mounting efficiency is improved. And the grounding risk caused by horizontal sliding launching righting hoisting is avoided.

    本发明涉及一种水上升压站基础的安装方法,水上升压站基础包括导管架,导管架上绑扎有浮箱,安装方法包括:将水上升压站基础固定在半潜船上,使导管架呈立式设置;控制半潜船下潜到预设深度,预设深度为能够使水对导管架的浮力大于或等于导管架与浮吊船的最大吊起重量的深度;将浮吊船的起吊装置与水上升压站基础的导管架相连接;解除导管架与半潜船之间的连接;控制浮吊船将导管架吊装至水上升压站的安装位置。本发明的安装方法能够借助水的浮力能够对导管架进行提升,降低了对浮吊船的最大吊起重量的要求,使得浮吊船能够满足立式吊装的需求,以立式吊装的方式将导管架吊装至水上升压站安装位置,避免了卧式滑移下水扶正吊装造成的触底风险。
