Large-scale dredging vessels (dredgers) are a key direction in the “Guidelines for Priority Development of High-Tech Industrialization Key Fields” by the National Development and Reform Commission, the Ministry of Science and Technology, the Ministry of Commerce, and the State Intellectual Property Office. They are the intersection of dredging engineering and ship engineering. Science and technology field. The results of this project are included in the national "Tenth Five-Year" major technical equipment development project "Automatic monitoring equipment for dredgers and efficient and durable machinery", the national 863 projects "Research on precision dredging technology of contaminated sediments", and the Ministry of Finance project "13500m3 large-scale automatic The first research and development and construction of the trailing suction dredger and the scientific and technological achievements formed under the support of the enterprise's self-research project.
After 6 years of joint research and application of production, education, and research by more than 100 technicians of the undertaker, substantial innovations and major breakthroughs have been made in advanced dredging technology and key equipment, as well as modern large-scale dredger design and construction technology, with complete independent knowledge property. Among the results, 1 invention patent and 9 utility model patents were obtained. In addition, 3 invention patents were published, 4 were accepted, 2 software copyrights were registered, 1 monograph and 4 sets of teaching materials were published, 1 enterprise technical standard was promulgated, and 25 papers were published. Articles. The main scientific and technical content includes large-scale dredger performance research and design and construction technology; dredger integrated platform management system; automatic dredging optimization technology; ship-shore information integration technology; standardization and serialization of dredging equipment and new wear-resistant material technology.
In the international dredging market, the self-built dredgers have repeatedly beaten European and American veteran dredging companies with excellent technical quality and won a number of overseas projects. More than ten ships have been exported overseas, and some standardized modules have been exported to developed countries in Europe and America. This achievement is an important turning point for my country from a major dredging country to a powerful dredging country, and it has a significant role in promoting technological leapfrogging and industrial structure optimization and upgrading in my country's high-tech shipbuilding industry and national dredging industry.
