Progress and Prospect of Deep-sea Heavy-duty Remotely Operated Vehicles

Abstract

Deep-sea heavy-duty remotely operated vehicles (ROVs) are essential equipment for the exploration of ocean resources, with remote operations being the primary method for addressing diverse deep-sea tasks. This paper introduces the classification, performance, and functional structure of deep-sea ROVs, provides a detailed analysis of device performance for various scenarios such as autonomous trenching machines, towed laying plows, and suspended jet operating robots in the context of undersea trenching and cable laying operations. This comparison should aid in the selection of equipment for different application scenarios. An analysis of existing sensor communication and control technologies, power supply, and integrated technology forms the basis for the discussion around future trends of distributed intelligent control systems, efficient power usage, safe power supply, and lightweight multifunctional integrated design. Finally, in consideration of China's current technology systems , the paper offers recommendations for the future development of deep-sea ROVs.
