Segmented offshore installation method for deepwater jacket
The invention discloses a segmented offshore installation method for a deepwater jacket. The method comprises the following steps that the deepwater jacket is divided into an upper section jacket and a lower section jacket to be built in a target site; the transportation barge ships the lower section jacket and transports the lower section jacket to a designated position; the lower-section jacket is put into water, and the bottom is leveled; the transportation barge ships the upper section jacket, transports the upper section jacket to a designated position and completes launching; the upper-section jacket is straightened by the crane ship, and the upper-section jacket and the lower-section jacket are in butt joint through an alignment device; after the upper-section jacket and the lower-section jacket are accurately butted, the upper-section jacket and the lower-section jacket are limited and fixed through a flange lock; and after the whole jacket is leveled, grouting is conducted on the pile foundation and the connecting position in sequence through a grouting machine, and installation is completed. According to the method, the dependence on large transport ship resources is reduced, the segmented jacket can be constructed, shipped and transported at the same time, the construction risk and the engineering investment cost are reduced, and the construction efficiency and reliability are improved.
本发明公开了一种深水导管架分段海上安装方法，包括以下步骤：将深水导管架分上段导管架和下段导管架分别在目标场地建造；运输驳船将下段导管架装船并运送至指定位置；将下段导管架下水，并进底部调平；运输驳船将上段导管架装船并运送至指定位置并完成下水；起重船扶正上段导管架，上段导管架和下段导管架通过对准装置完成对接；上段导管架和下段导管架准确对接后，通过法兰锁具完成上段导管架和下段导管架的限位固定；导管架整体调平后利用灌浆机对桩基础和连接处依次灌浆，完成安装。本发明不仅降低了对大型运输船舶资源的依赖，分段的导管架可以同时建造、装船和运输，降低了施工风险和工程投资成本，提高了施工效率和可靠性。
