摘要
对海底油气输送管道进行挖沟填埋是一种常用的保护方法。文中综述了海底管道主要的挖沟方法及其适用的挖沟设备,分析了各种挖沟方法的优缺点及其适用条件。通过具体工程案例分析了不同管段海域水深、地质条件、挖沟深度等实际情况,在不同的管段采取相应的挖沟方法,选用合理挖沟机械;保证了工程进度,提高了效率,节约了成本,满足预定要求。
Trenching is a common method of protection for subsea oil and gas transmission pipeline.In this paper,the major subsea pipeline trenching method and trenching equipments were summarized,and the advantages and disadvantages of all kinds of trenching methods were analyzed.According to specific project,water depth,geological conditions and depth of trench in different pipe section were analyzed in this paper.The corresponding trench methods were adopted in different sections,thus ensuring the project progress,improving the efficiency,saving the cost and meeting the reserve requirements.
