流花4-1油田海缆铺设安装关键技术研究及应用

The study and application of the key techniques for cable laying in LH 4-1 oilfield

流花4-1油田是我国第一个自营开发的深水油田,针对该油田深水开发的特点,对海缆运输和铺设方案选择、脐带缆起始铺设终端精准定位下放、海缆铺设防止打扭、海缆卡子与锚定结构的水下连接、特殊设计的海缆回接提拉等关键技术进行了研究,并在该油田海缆铺设安装和回接施工作业中取得了良好成效。这些关键技术将为其他深水开发油田的海缆安装设计及实施提供借鉴和参考。

LH 4-1 oilfield is the first self-developed deep water oilfield in China. Based on the character- istics of the field, studies were conducted on some key techniques such as the optimization of the cable transportation and laying plan, precise deployment of UTH, cable twist prevention, clamp installation on subsea anchor as well as the cable tieback to plat- form, etc. A great success of cable laying and tie- back operation was achieved by applying these tech- niques in the field. These techniques will be used as references for the cable laying design and implemen- tation in other deepwater oilfield.
