摘要
埕岛油田地处黄河口滩海交界地带，大面积区域冲刷造成海底管线出现悬空安全隐患。海底仿生防冲刷保护系统基于海洋仿生学原理，通过仿生海草的粘滞阻尼作用，降低海流流速，促进泥沙淤积，其应用于埕岛油田海底管线悬空治理具有显著的促淤埋管效果。介绍了该系统的特点、防冲刷作用机理以及应用效果，为河流及海底管线的防护提供参考。
Chengdao oil-field is located in the river-sea borderland, of which parts of subsea pipeline are suspended due to long-range regional scour. Bionic scour prevention system, an advanced technology based on bionics, has positive effect on handling suspension of subsea pipeline, and bionic straw is a kind of product with viscosity resistance which can reduce the current speed and accelerate sand deposit. In this paper, the characteristics of this system, mechanism of scour and application effect are introduced which can provide a model for other pipelines located in river or sea.
