- 摘要:
- 介绍了一种海底管道悬空裸露检测的新方法,即多波束测深技术,该技术可精确获得海底管道悬空裸露的长度和高度,直接反映海底管道的三维空间状态,从而确定海管水下运行状态和水下治理的准确工程量,为下一步安全运行管理和隐患治理提供科学依据。同时,还能精确测出海管后挖沟的深度及海管在沟底中的空间位置,为后挖沟施工效果评价与施工方案调整提供依据。文章具体介绍了多波束测深系统的组成、工作原理以及海管悬空裸露和后挖沟效果的检测方法。多波束测深技术为海底管道的检测工作提供了一条更快捷、直观、精确的新方法。
Applying multi-beam echo sounding technology can accurately obtain the length and height of suspended and exposed sections of subsea pipeline,and give pipeline 3D image,thus determine subsea pipeline operational status and exact treatment quantities needed.It offers the scientific basis for further pipeline safety management and hidden trouble treatment.In addition,multi-beam echo sounding technology can accurately measure the post trenching depth and the pipeline spatial position on the trench bottom for evaluating post trenching effect and regulating construction scheme.The composition and working principle of the multi-beam echo sounding system and the inspection method for suspended and exposed pipeline as well as the post trenching effect are concretely described.Multi-beam echo sounding technology provides a faster,more intuitive and more accurate method for subsea pipeline inspection.2012,05(05): 58-60 收稿日期：2012-2-28分类号：TE973.6作者简介：崔双民（1967-），男，河北昌黎人，高级工程师，1991年毕业于大庆石油学院，现从事工程管理工作。参考文献：
