Recently, the Tianjin Municipal Bureau of Industry and Information Technology issued the "Tianjin Catalog for the Promotion and Application of Major Technical Equipment (First Set) (2024 Edition)", in which the"Intelligent-Green Integrated Waterborne Complete Equipment for Ecological Desilting and Sediment Disposal in Rivers, Lakes and Reservoirs" — the "Taihu Star" — independently developed by CCCC Tianjin Dredging Co., Ltd.was successfully selected. This is not only recognition of the company's capacity for independent technological innovation, but also important affirmation of the leading and demonstrative role the company plays within the industry.

The "Taihu Star" possesses fully independent intellectual property rights and is the world's first engineering vessel of its kind. It integrates functions such as ecological desilting, sediment solidification and tailwater treatment, and consists of three parts: the new intelligent eco-friendly desilting vessel "Taihu Junqing 1", the impurity removal and conditioning vessel "Taihu Star No. 1", and the dewatering and volume reduction vessel "Taihu Star No. 2". It features innovation highlights and technical advantages including flexible operation, highly efficient production, integrated functions, green and low-carbon operation, intelligent management, and independent intellectual property rights. Its dredging concentration can reach over 50%, and its overall dredging efficiency is three times that of ordinary cutter suction dredgers, enabling a stable daily desilting capacity of 5,000 cubic meters. The three vessels are linked in series, each performing its own function in perfect coordination, completing sediment dewatering, solidification and harmless treatment on the water surface, thoroughly resolving the problem of land resource occupation caused by sediment solidification.

At present, the "Taihu Star" has been successfully applied to the new round of the Taihu ecological desilting project. Relying on the world-leading high-concentration dredging process and the supporting factory-style integrated waterborne in-situ sediment treatment method, it redefines the operating model of desilting projects. Through a multi-dimensional sensing and multi-system collaborative integrated intelligent operation system, it achieves a high degree of equipment integration and efficient coordination, substantially improving equipment production efficiency, reducing personnel labor intensity, lowering dependence on land resources, eliminating secondary pollution from transfer, and standardizing ecological desilting projects.

This set of equipment is a vivid practice of implementing Xi Jinping Thought on Ecological Civilization, and is of great significance for promoting the intelligent, green and collaborative development of ecological governance of "rivers, lakes and reservoirs". Previously, this equipment technology was appraised by the China Machinery Industry Federation as the highest grade of scientific and technological achievement — internationally leading level — and was included in the "Tianjin Green Technology Promotion Catalog (2024 Edition)" issued by the Tianjin Municipal Development and Reform Commission.

Major equipment (first set) refers to equipment products that achieve technological breakthroughs and possess independent intellectual property rights through original innovation, integrated innovation, or the digestion, absorption and re-innovation of introduced technologies, including complete sets of equipment, whole machines and core components. The first-set major equipment certification carried out by the Tianjin Municipal Bureau of Industry and Information Technology this time aims to encourage and guide equipment enterprises in technological innovation and to promote the innovative development, promotion and application of first-set major technical equipment.

Next, CCCC Tianjin Dredging Co., Ltd. will continue to advance the certification of China's first-set major technical equipment, further increase investment in research and development, adhere to placing equal emphasis on governance and development, and continue to optimize equipment technology, improve equipment performance and expand the scope of application,continuously delivering new quality productive forces to the fields of ecological governance of "rivers, lakes and reservoirs" and energy conservation and environmental protection,and contributing the strength of Tianjin Dredging to industrial upgrading and scientific and technological progress.
