摘要
2006年11月在茂名海底输油管线悬空路段成功完成人工海草的海底种植安装,2007年4月通过潜水人员水下检测、海流测量等工作,检查了海底人工海草的状态。检测发现,人工海草尚未被破坏时,确实具有明显降低海流流速和促进泥沙淤积的功能。1.0 m高的人工海草实际效果要好于0.5 m高的人工海草;尽管海草草体已吸附了大量悬浮泥沙,多数海草出现倒伏和部分掩埋的现象,但仍然可降低流速15%-20%;人工海草垫直接铺设于海底管线之上,比铺设于海底管线之一侧更有利于管线的保护。
Artificial seaweeds were fixed in hanging segment of submarine oil pipelines in Maoming in November 2006,and the state of artificial seaweed was checked by divers,according to submarine investigation and current measure.The results showed that artificial seaweeds surely had obvious effect on current slowing and silting urging,and that the artificial seaweeds of 1m length seemed to be more effective than that of 0.5m length.Although the seaweeds absorbed a lot of suspend mud of seawater,and majority of seaweeds were lodged and partly buried,however the current flowing through artificial seaweeds could be 80 percent or 85 percent.Artificial seaweed bedding laid on the pipeline would be better for the protection of pipeline than that on one side of the pipeline.
