The invention discloses a jacket platform distribution pipe clamp type submarine cable installation method, which comprises the following steps of determining pipe clamp installation positions according to a platform anchoring position, and fixedly connecting a plurality of pipe clamps to a protection pipe at the platform anchoring bottom end; adjusting the coaxiality of the plurality of pipe clamps, and reserving signal cables in the pipe clamps; an anchoring base plate is installed on the workboat; the platform worker connects the platform winch steel wire rope to the signal cable, and the workboat restores the platform winch steel wire rope to the workboat deck through the signal cable; the workboat connects a platform winch steel wire rope to the end part of the newly-built submarine cable, and the platform winch drags the newly-built submarine cable; an anchoring part is arranged on the newly-built submarine cable, and the ROV connects the anchoring part to the anchoring base disc; dragging the newly-built submarine cable to penetrate through the pipe clamps to reach the anchoring position of the platform, and fixing the newly-built submarine cable through the anchoring flange to complete submarine cable installation. Submarine cable installation can be completed under the condition that no submarine cable J-shaped pipe is reserved on the platform, the installation workload is reduced, and the cost is saved.
本发明公开了一种导管架平台分布管卡式海缆安装方法,包括以下步骤:根据平台锚固的位置,确定管卡安装位置,若干管卡固定连接于平台锚固底端的护管上;对若干管卡进行同轴度的调整,并在管卡内预留信号缆绳;施工船安装锚固基盘;平台人员将平台绞车钢丝绳连接至信号缆绳,施工船通过信号缆绳将平台绞车钢丝绳回收至施工船甲板;施工船将平台绞车钢丝绳连接至新建海缆的端部,平台绞车对新建海缆进行拖拉;新建海缆上设置锚固件,ROV将锚固件连接至锚固基盘;拖拉新建海缆穿过若干管卡后至平台锚固处并使用锚固法兰将新建海缆固定,完成海缆安装。本发明能够在平台无预留海缆J形管的情况下完成海缆安装,减少安装工作量,节约成本。
