Optimizing deployment processes and control strategies for marine submerged buoy system: A computational approach

Abstract

This study addresses the underwater deployment methods of submerged buoy systems, aiming to meet the challenges posed by highly variable underwater environments. Submerged buoy systems, deployed to target sea regions for extensive detection and data collection tasks, are advanced modern monitoring tools. Compared to traditional surface deployment methods, underwater deployment can avoid disturbances caused by ship-generated waves and surface wave loads, meeting the precision requirements of acoustic detection instruments. This paper proposes a novel underwater deployment method tailored to actual engineering scenarios and provides a detailed explanation of the hydrodynamic modeling approach for deploying submerged buoy systems to anchorage points. Key aspects discussed include the selection of component models, the application of loads during deployment, precise positioning, and the control of tension and oscillations of submerged buoys. Simulation results show that this method minimizes the frequency range where environmental and system oscillations intersect, effectively controlling submerged buoy oscillations and enhancing the performance of subsequent monitoring system signals. The findings of this study are significant for improving submerged buoy deployment techniques, offering valuable theoretical and practical insights.
