During the eleventh five-year plan period, China's large modern dredgers were mainly imported and transformed into a new stage of independent development and construction. China communications group invested 20 billion yuan to build a new large dredger. Bureau of Shanghai airlines by independently designed and built in 2005, four capacity 200 m3 small modern trailing suction vessel "navigation deepened 4011" after gaining experience, in 2006, independent building 13, 500 m3 capacity big, modern trailing suction hopper dredger "new sea tiger", China has a large modern dredger's capacity for independent design, build, and become the world's few grasp the mainstream technology in the world. In 2010, "tongcheng", an ultra-large trailing suction dredger designed and built by China, with a depth of 85 m, was put into operation, marking China's initial capability of designing and building ultra-large modern dredger, and the leapfrog development of dredging pipeline equipment technology in China.
Through the cooperation of industry, university and research institute, China has also solved the basic and common frontier technology of dredger design and manufacture, such as the optimal power management system of dredger in dredging pipeline. On the basis of the application of basic research results, key technology integration achievements and successful practice of old ship transformation, during the tenth five-year plan period, 11 new large trailing suction dredgers of more than 8,000 m3 were added to China's transportation system, with an additional capacity of 110,000 m3. Water conservancy system "100 ships plan" and rapid development of some private enterprises, also built many small and medium-sized rake suction ship, increased cabin capacity is also very considerable.
