On the 19th, it was learned from Tongji University that China's first ocean level intelligent scientific research vessel, the "Tongji", has recently completed a ship trial voyage. The trial voyage lasted for 8 days and completed over 100 test projects, including overall performance, residential environment vibration noise, underwater radiation noise, intelligent navigation, and remote control system. All test results met the standards. The ship's maneuverability, maximum speed, living environment, and other performance indicators are all superior to the design specifications. It is reported that the "Tongji" ship, as a 2000 ton marine scientific research and teaching support vessel, can be used in unlimited navigation areas (excluding ice areas) and has all-weather operational capabilities. In terms of ship power, the "Tongji" adopts an advanced hybrid power system of "DC busbar+lithium iron phosphate battery pack". The lithium battery pack plays a role in peak shaving, valley filling and energy recovery, reducing energy consumption by about 8% compared to similar scientific research ships. The intelligent energy efficiency system and intelligent route planning function of the ship can improve navigation efficiency and save operating costs by about 3% to 5%. In terms of scientific research capabilities, the "Tongji" has shown outstanding performance. It can carry operational ROVs (underwater remote-controlled robots), multiple containerized shipborne laboratories, and has comprehensive self-organizing network functions for mobile and fixed observation nodes. It can meet the comprehensive scientific research tasks of marine geology and geophysics, physical oceanography, marine chemistry, marine biology, atmospheric environment, etc. It can carry out comprehensive investigations of seabed topography and geomorphology, sediment and structure, marine environment and ecology, as well as marine investigation equipment testing. It can also undertake offshore engineering tasks such as fault detection, maintenance, laying and post burial, seabed routing investigation and scanning, wind power engineering survey, etc., providing equipment support for marine scientific research and the cultivation of marine related professionals. It is worth mentioning that the exterior design, driving and living quarters of the ship, led by the School of Design and Creativity at Tongji University, have received unanimous praise from nearly 20 participating units. The scientific research vessel is designed as a "floating innovation community", with a stylish appearance and a warm interior like a "home". Building a technologically advanced research vessel that meets the needs of disciplinary development is of great significance for building a world-class marine discipline and contributing Tongji's strength to the construction of a maritime power. ”Vice President of Tongji University, Shi Zhenming, said. The reporter learned that the "Tongji" ship will start construction in Guangzhou in April 2024, integrating scientific research, talent cultivation, popular science education, and cultural heritage. It is a "maritime campus" that Tongji University is committed to building, which will meet the needs of Tongji University's marine disciplines and other units for scientific exploration voyages, offshore engineering construction tasks, and student maritime internships. Next, the first scientific expedition of the "Tongji" is expected to be launched in August 2025, and will conduct a multidisciplinary comprehensive survey in the South China Sea for nearly a month.
