Installation method for composite cable of newly-built ocean platform
The invention provides an installation method for a composite cable of a newly-built ocean platform. The installation method for the composite cable of the newly-built ocean platform comprises the following steps: before the ocean platform enters water, fixing an anchoring structure to the bottom of the ocean platform; fixing a tensioning device and a junction box to the top of the ocean platform;connecting the top end and the bottom end of the composite cable fixed with an auxiliary anode and a first reference electrode with the tensioning device and the anchoring structure separately; leading a cable core wire at the top end of the composite cable into the junction box through a branching cover fixed on the cable core wire; adjusting a tensioning force through the tensioning device so as to enable the composite cable to be in a tensioned state; and installing the ocean platform into a designated sea area; and putting the ocean platform into a fixed sea area. According to the invention, lifting lugs on main legs, and the tensioning device are adopted for tensioning the composite cable, and due to the fact that the lifting lugs are simple in structure and convenient to install, and all the work of tensioning the composite cable is completed before the ocean platform enters water, the construction steps are reduced, the offshore construction period is shortened, the construction cost is reduced, the construction difficulty is lowered, and meanwhile the construction risk is reduced.
本发明提供一种新建海洋平台的复合缆的安装方法，如下步骤：海洋平台下水前，将锚固结构固定在海洋平台的底部；将张拉装置和接线箱固定于海洋平台的顶部；将固定有辅助阳极和第一参比电极的复合缆的顶端和底端分别与张拉装置和所述锚固结构连接；复合缆顶端的电缆芯线经固定在其上的分线罩引出至接线箱内部；通过张拉装置调整拉紧力，使复合缆处于张紧状态；将海洋平台安装在指定海域。将海洋平台放入固定海域。本发明采用主腿上的吊耳和张拉装置对复合缆进行张紧，由于吊耳结构简单，安装方便，并且在海洋平台入水前完成所有对复合缆进行张拉的工作，使施工步骤缩减，降低了海上施工周期、施工成本及施工难度，同时减少施工风险。
