Application of Acoustic Detection Technology in the External Detection of Submarine Pipeline

在海底管道的外检测过程中,为明确海底管道的真实赋存状态,常使用工程物探和潜水摸探对其进行调查,其中声学探测技术的应用最为广泛。本文以SONIC 2024多波束测深系统、SES 2000参量阵浅地层剖面系统、KLEIN 3000侧扫声呐系统为例,系统介绍传统声学探测技术在北部湾某单点系泊(SPM)海底输油管道外检测中的应用。在此基础上,结合扫描声呐、合成孔径声呐等声学探测技术,探讨各类声学探测技术的优劣性及适用条件,指出海管外检测技术的发展方向。多种声学探测技术的综合运用是准确评价海底管道状态的基础,海底管道外探测方案的选择应综合考虑海域条件、设备优缺点、作业载体、工作成本等因素。海管外检测技术向着设备集成化、检测精细化、识别智能化的方向发展。

In the external detection process of submarine pipelines,in order to clarify the true existence status of submarine pipelines,engineering geophysical exploration and diving exploration are often used to investigate them,and acoustic detection technology is the most widely used.Taking a single point mooring(SPM)and submarine oil pipeline in Beibu Gulf as an example,the application of SONIC 2024 multi-beam sounding system,SES 2000 parametric sub-bottom profile,KLEIN 3000 side scan sonar system and other traditional acoustic detection equipment in the detection of submarine pipelines was systematically introduced.And on this basis,combined with acoustic detection technologies such as scanning sonar,synthetic aperture sonar,the advantages,disadvantages and applicable conditions of various acoustic detection technologies were discussed,and the technology development direction of external detection of submarine pipeline was pointed out.The comprehensive application of a variety of acoustic detection technologies is the basis for accurate evaluation of the state of submarine pipeline.The selection of submarine pipeline detection scheme should comprehensively consider factors such as the sea area conditions,advantages and disadvantages of equipment,operation carrier,work costs.And the detection technology of submarine pipeline is developing towards the direction of equipment integration,detection refinement and recognition intelligent.
