摘要
以曾两次因冲刷悬空而发生事故的平湖油气田岱山近岸段KP2.6为例,通过比较挖沟、传统抛石、砂袋支撑、水泥压块以及仿生草技术等悬空处理与冲刷控制措施,提出了"砂袋悬空回填与仿生草永久性冲刷防治"方案,系统地探讨将仿生草技术用于东海海底管线的防护,对东海乃至全国海底管线悬空处理与冲刷防治都有借鉴价值。
Taking the KP2. 6 near Dai-shan shore approach of Ping-hu Oil and Gas field as an example, which damaged twice by the scour, comparing with the trenching, traditional stone dumping, sand bags support and concrete mattresses, and bionic scour-prevention technique, sand bags support for free-span back fill and frond mats are recommended for permanent scour prevention, and this is the first time to systemicly discuss the bionic scour- prevention technique for the subsea pipelines in the east china sea, so there will be important applied value and practical significance for scour protection and free-spans rectification of subsea pipeline in the east china sea.
