The invention discloses a mounting method for an upper module of an offshore platform, and belongs to the technical field of offshore platform mounting. The method comprises: loading a platform superblock onto a first vessel; the second ends of the first supporting rod and the second supporting rod are both connected with the platform upper module loaded on the first ship, and the first ends of the first supporting rod and the second supporting rod are connected to the second ship and the third ship on the two sides of the first ship correspondingly; the distance between the second ship and the third ship is shortened, and the platform upper module is jacked to the preset height; the second ship and the third ship are moved, so that the supporting legs of the platform upper module are aligned with the pile legs of the platform lower structure; and the distance between the second ship and the third ship is increased, and butt joint of the supporting leg and the pile leg is achieved. According to the method, the supporting rods are adopted for jacking and lowering the upper module of the platform, flexibility is high, and the method does not depend on the sea area environment. In addition, the method is not only suitable for deep sea operation, but also suitable for construction in a shallow water area, and the applicability is high.
本发明公开了一种海上平台上部组块安装方法,属于海上平台安装技术领域。该方法包括:将平台上部组块装载到第一船舶上;将第二端均与装载到第一船舶上的平台上部组块连接的第一支撑杆和第二支撑杆的第一端分别连接到第一船舶两侧的第二船舶和第三船舶上;缩短第二船舶和第三船舶之间的距离,将平台上部组块顶升至预设高度;移动第二船舶和第三船舶,使平台上部组块的支撑腿与平台下部结构的桩腿对正;增大第二船舶和第三船舶之间的距离,实现支撑腿与桩腿的对接。本方法采用支撑杆对平台上部组块进行顶升和下放,灵活性较强,并且不依赖海域环境。此外,本方法不仅适用于深海作业,也适用于浅水域的施工,适用性较强。
