超短基线和2D扫描声呐联合调查方法在海洋工程中的应用

Application of ultra short baseline and 2D scanning sonar joint survey method in ocean engineering

在障碍物打捞和海缆裸露悬空治理过程中,对施工动态的掌握和施工质量的把控是重要环节。MS1000在海底地貌测量精度、声像图分辨率、时效性方面具有独特的优点,且USBL在定位精度上有不可比拟的优势。采用MS1000和USBL联合调查的方法,能有效增强不同观测数据的互补性,显著提高工程质量。结合其在某海缆裸露悬空隐患治理和某海床潜水打捞工程中的应用实例,证实了该方法的有效性和实用性,可显著提升作业精度和效率,避免重复的施工流程,为海底管道维护治理工程和潜水打捞提供参考。

In the process of obstacle salvage and treating exposed and suspended submarine cables,it is important to grasp the construction dynamics and control the construction quality.MS1000 has unique advantages in measuring accuracy of underwater topography,resolution of acoustic images,and timeliness,while USBL has unparalleled advantages in positioning accuracy.The joint survey method of MS1000 and USBL can effectively enhance the complementarity of different observation data and significantly improve engineering quality.Combined with its application examples in the treatment of hidden dangers of exposed and suspended submarine cables and a submarine salvage project,the effectiveness and practicality of this method have been confirmed.It can significantly improve the accuracy and efficiency of operations,avoid repetitive construction processes,and provide reference for submarine pipeline maintenance and salvage projects.
