Translated from the People's Daily
On August 26, China's independently designed and developed "Tongjun" and "Junguang" ships successfully launched in Qidong, Jiangsu. These two ultra-large suction hopper dredgers with a 35,000 cubic meter cargo capacity have immediately earned the titles of "Asia's largest" and "world-leading", and are hailed as "national treasures" in the dredging industry.
These two "dredging twins" exude the confidence of "Chinese manufacturing" from head to toe. From concept design to intelligent system development, from ship design by China Ship Scientific Research Institute No. 708 to construction by Shanghai Zhenhua Heavy Industries, the entire chain has achieved "domestic ships built domestically". With a length of 198 meters, a width of 38.5 meters, and a depth of 18 meters, they have the largest 35,000 cubic meter mud tank in Asia, and their maximum digging depth can reach 120 meters, equivalent to extending the suction head to the ocean floor at the height of 40 floors for "operations."
Don't think they're just "big beasts." Their level of intelligence is also top-notch. The self-developed "One-click Dredging" and "Jundriving Integration" systems allow one crew member to handle the entire process of navigation and construction. From dredging, transporting, to filling, all operations are intelligently managed. Moreover, they are particularly capable, excelling in strong soil breaking, deep digging, long transport distances, and long filling distances. They can handle port and harbor dredging, deep-sea sand extraction, land reclamation, and even deep-sea mining. They can operate stably in waves of eight levels, and can fill a 35,000 cubic meter mud tank within 90 minutes, maintaining a leading position in loading efficiency worldwide.
More proudly, the birth of these two dredgers is full of innovation. During construction, the "digital dock + modular construction" approach was used, directly increasing efficiency by 20%. Every link, from design to equipment, embodies the wisdom of Chinese enterprises. Their successful launch not only marks that China's dredging equipment has completely moved from "following" to "leading," but it is also a vivid reflection of China's transformation from a "major manufacturer" to a "smart manufacturing power." In the future, after being put into use, they will further enhance the professionalism and internationalization of China's dredging fleet, helping China steadily move from a major dredging country to a powerful dredging nation.
