浅海海底管道探测技术探讨

Analysis of Technology Used for Submarine Pipeline Detection in the Shallow Seas

近年来,随着我国海洋资源的不断开发,越来越多的海洋油气资源采用海底管道(输油、输气等)输送到陆地。这些管道长期在水深较浅的海底中,容易受到风浪、潮流或其他外力作用,一旦发生悬空或断裂,不仅会造成大量的经济损失,而且可能产生重大的海洋污染,从而带来巨大的社会不良影响。因此,对海底管道定期检测非常重要。海底管道铺设后要进行检测,探明海底管道在海底的实际状态,查明受破坏的程度和位置,以便进行维护。通过分析表明,采用测深仪、SES-96声参量阵极浅地层剖面仪及侧扫声呐进行综合探测是比较有效的方法。

With continuous exploitation of marine resources in recent years, a growing number of submarine pipelines （oil, gas, etc. ） have been used to transport offshore oil and gas resources to the land. These pipelines are chronically buried in the seafloor cov- ered with shallow water and are vulnerable to waves, tides or other hydrodynamic forces. Once they are dangled or broken, not only large amount of economic loss will be caused, but also a serious marine pollution can possibly be produced, hence bringing a- bout greater social adverse effects. Therefore, it is very important to detect the submarine pipelines termly. For the purpose of maintenance, it is necessary to know the actual state of submarine pipelines after their laying and the extent and position of the pipeline damages. The analysis of Hainan 8 submarine pipeline indicates that a comprehensive detection by using echo sounder, SES-96 high-precision shallow stratum profiler and side-scan sonar is more effective.
