中国自主研制超大型耙吸挖泥船“通浚”轮成功完成海试

Core Viewpoint - The successful sea trial of China's self-designed and built ultra-large dredging vessel "Tongjun" marks its readiness for production, supporting national maritime power construction and the Belt and Road Initiative [1]. Group 1: Sea Trial Details - The sea trial commenced on November 21 and lasted for 5 days, during which "Tongjun" completed 30 major items and 91 sub-items of rigorous testing [1]. - The vessel demonstrated key performance indicators that met or exceeded design standards under complex sea conditions [1]. Group 2: Vessel Specifications - "Tongjun" is China's first self-designed ultra-large dredging vessel with a capacity of 35,000 cubic meters, featuring a maximum capacity of 38,168 cubic meters, ranking first in Asia and second globally [1]. - The vessel is equipped with two 9,000 kW internal mud pumps capable of achieving a 12-kilometer long-distance discharge operation, with a single dredging operation able to fill a standard soccer field to a height of 5 meters [1]. Group 3: Operational Capabilities - The sea trial focused on verifying the vessel's unlimited navigation capability and adaptability to harsh sea conditions, including speed measurement, turning, Z-shaped maneuvering, and heading stability tests [2]. - The vessel is suitable for various construction scenarios, including port dredging, land reclamation, coastal maintenance, deep-sea sand extraction, and deep-sea trench excavation and backfilling, achieving full coverage of dredging operations [2]. Group 4: Intelligent Systems - "Tongjun" features an advanced intelligent dredging control system and intelligent navigation system, enabling full-process intelligent control from precise navigation positioning to efficient dredging operations [2]. - The vessel's intelligent operation mode covers the entire chain of "dredge - transport - discharge," with its level of intelligence being internationally leading [2]. Group 5: Certification - "Tongjun" is the world's first vessel to obtain the i-ship (Da,m,o) intelligent dredging class notation [3].
