Core Viewpoint - The "Dongfanghong 2" marine comprehensive scientific research training vessel has successfully completed a significant upgrade, enhancing its capabilities for global navigation and multi-disciplinary exploration [2] Group 1: Vessel Upgrade and Capabilities - The vessel has undergone a core modification, enabling it to operate in unlimited maritime zones and conduct global voyages [2] - Post-upgrade, the vessel can simultaneously carry out hydrological, meteorological, and physical multi-disciplinary comprehensive detection in both continental shelf and oceanic areas [2] - The "Dongfanghong 2" is recognized as a significant asset in China's marine science and education sector, having been in operation since January 1996 [2]

Core Viewpoint - The successful launch of the "Dongfanghong 2" ocean comprehensive scientific research training vessel marks a significant milestone in its core renovation, enhancing its capabilities for China's marine scientific education and research endeavors [1][5]. Group 1: Vessel Background and Historical Significance - "Dongfanghong 2" was built in 1993 and officially entered service in January 1996, serving for 27 years and covering 600,000 nautical miles, equivalent to 28 circumnavigations of the Earth, and has set multiple records in China's scientific research [5][13]. - The vessel has undergone significant wear and tear over the years, necessitating a comprehensive renovation to address issues such as rust, wear, aging, and functional decline [5][8]. Group 2: Renovation Objectives and Achievements - The renovation aimed to "restore functionality, expand capabilities, and optimize performance," achieving upgrades in six key areas: vessel control and power systems, scientific research system functionality, operational space optimization, navigation performance enhancement, user experience and cost optimization, and extending the vessel's lifespan [8][13]. - Post-renovation, the vessel is equipped with "unlimited navigation area and global sailing" capabilities, allowing it to operate continuously at sea for 60 days without resupply, enabling research across various marine fields [13][16]. Group 3: Technological Innovations and Future Implications - The renovation incorporated advanced technologies, including specialized vibration and noise reduction processes to minimize interference with precision scientific equipment, and customized installation solutions to address compatibility issues between new equipment and the existing vessel structure [13][16]. - The project reflects the commitment of Wuchang Shipbuilding to support China's "marine power" strategy, revitalizing a significant research vessel and contributing to the nation's marine scientific endeavors [16].
