Core Viewpoint - The successful launch of the "Tongjun" and "Junguang" dredging vessels marks a significant advancement in China's maritime engineering capabilities, showcasing the country's self-reliance in developing large-scale dredging equipment and technology [7][19]. Industry Overview - China's marine economy has rapidly developed, with the marine production value exceeding 10 trillion yuan, driving the growth of the port and channel infrastructure dredging market [9]. - The trend in domestic port construction is towards larger and deeper projects, necessitating advanced dredging technologies [9]. Vessel Specifications - The "Tongjun" and "Junguang" vessels have a maximum dredging depth of 120 meters and a mud hold capacity of 35,000 cubic meters, capable of raising a standard soccer field by 5 meters with a single load [14]. - Both vessels are equipped with a heavy-duty dredging head and high-pressure water systems, allowing them to excavate hard soil and weakly weathered rock [14][15]. Technological Innovations - The vessels feature an intelligent dredging operation system that allows for automated control, enabling a single crew member to manage operations efficiently [18]. - The implementation of digital twin technology provides real-time visualization of underwater conditions, enhancing operational precision [18]. Construction Achievements - The simultaneous construction of these two vessels in a 300,000-ton dock is a global first, demonstrating advanced modular construction techniques and digital management [19]. - The construction process involved over 2,000 workers and utilized a digitalized dock system to ensure precision and efficiency [19]. Future Applications - The vessels are expected to play a crucial role in various complex operations, including deep-water port dredging, underwater pipeline construction, and marine resource extraction [19].
