柔性软管是海洋油气开发中的重要组成部分，其海上安装是海洋工程公司核心能力与关键技术的体现。依托我国第一个自主开发的1500m级超深水陵水17-2气田，基于国内首艘3000m级大型深水多功能工程船“海洋石油286”，对“海洋石油286”采用竖直铺设方法进行1500m级水深柔性软管安装的可行性进行了评估。在此基础上，对超深水柔性软管竖直铺设关键技术及解决方法进行了研究。通过陵水17-2气田中的工程应用，验证了相关技术的可行性，填补了国内技术领域的空白，为今后深水柔性软管安装提供了技术储备和经验借鉴。

Flexible flowline is an important part of offshore oil and gas development， and its offshore installation is the core ability and key technology of offshore engineering companies. Based on China's first self-developed 1500m ultra-deep water Lingshui 17-2 gas field， and the domestic first 3000m-class deep-water MSV “Hai yang Shi You 286”， the installation feasibility of 1500m water depth flexible flowline by vertical-lay method for “HYSY 286” is evaluated. The key technology and solution of vertical-lay of ultra-deep water flexible flowline are studied. Through the engineering application in Lingshui 17-2 gas field， the feasibility of the relevant technology is verified， and the gap in domestic technology field is filled， and the technical reserve and experience are provided for the installation of deep water flexible flowline in the future.
