海洋油气田水下设施的防渔业损坏

为保障海洋油气开采的安全和顺利,文章以我国南海东部海域为例,在概述渔场和渔船基本情况的基础上,分析拖网对海洋油气田水下设施可能造成的损坏,并提出相关建议。研究结果表明:对海洋油气田水下设施影响最大的捕捞作业方式是拖网;双拖网渔船产生的最大拖曳力远大于脐带缆所能承受的最大拉力,很有可能损坏脐带缆等水下设施;应对渔船作业水域的海洋油气田水下设施采取保护措施,限制可能损坏水下设施的渔船作业,加强管理和培训以及通过技术手段对相关情况进行监测和处理。

Underwater Production Facilities Protection against Trawling Damage

In order to protect the safety and successful of the offshore oil and gas exploitation,this paper analyzed the possible facilities damage by the trawling,based on the investigation of the fishery companies and fishing vessels in the eastern South China Sea,and suggestions were proposed.The research showed: the most dangerous fishing operation for the offshore oil and gas facilities was trawling; the maximum drag tension by the double trawlers were much larger than the maximum tension of the umbilical,and would possible damage the umbilical etc.; protection against the trawling damage should be applied,and the fishing operation which would possibly damage the facilities should be limited,the management training and monitor,and technical means should be strengthened to deal with relevant situations.
