海底观测网深水设备精准定点布放方法研究

海底观测网因其实时、长期、连续、高精度时钟同步及原位等优势而逐渐成为人类研究海洋的新型平台,建设规模和应用水深都在不断扩大。海底观测网系统建设中,深水设备的精准定点布放及湿插拔作业是施工的难点。针对国内海底观测网精准定位布放作业存在的困难和问题,结合国内现有施工条件,提出一种大深度海底设备精准定点布放安装方法,实现南海深海海底观测网试验系统深水设备精准定位布放与ROV湿插拔作业,对未来大规模海底观测网及其它深水工程中设备的精准定点布放和安装,具有参考和借鉴意义。

Research of Precision Deployment for Equipment of Seafloor Observatory Network in the Deep Sea

The seafloor observatory network has gradually become a new platform for ocean exploration and marine research owing to its advantages of real-time,long-term,continuous,high-precision clock synchronization and in-situ observations,with its construction scale and practicing depth constantly expanding.The precision positioning and installation of deep-water equipment and the operation of wet-mate connectors are the key processes in the construction of the seafloor observatory network.Aiming at solving the difficulties and problems in the precision positioning and deployment of the seafloor observatory network in China,and considering the existing conditions,a precision positioning and deployment method for deep-water equipment has been applied to the ROV wet-mate connecting operation and the construction of the deep seafloor observatory network test system in the South China Sea.This method will provide significant reference for the precision positioning and deployment of equipment in deep-sea projects such as a large-scale seafloor observatory network in the future.
