On August 26th, at the Yangtze River estuary, China successfully launched the ultra-large grab suction dredgers "Tongjun" and "Junguang", the largest in Asia and world-leading, marking the new flagship of the "island-building marvels." The dredger "Junguang", a Guangdong-built "advanced equipment for the country," has already secured 24 national invention patents. It is scheduled for sea trials this year and will be delivered for operation at the Guangzhou Port by year-end.

The "Tongjun" and "Junguang" are designed with a length of 198 meters, a width of 38.5 meters, and a depth of 18 meters, with a maximum dredging depth of 120 meters. Their capacity reaches 35,000 cubic meters, equivalent to the total volume of 18 standard swimming pools, ranking first in Asia.

Even under the conditions of waves and winds of up to grade eight, the dredgers' cutter heads can reach seabed depths equivalent to approximately 40 stories, suctioning and loading sediment. The hoppers can be fully filled within 90 minutes, demonstrating world-leading loading efficiency.

In addition to their large capacity, both vessels are equipped with methanol-ready dual-fuel engines, achieving 30% higher power efficiency compared with similar ships. With this green innovation, the two dredging marvels are capable of unrestricted global navigation.

Moreover, both dredgers adopt an integration of 5G and the BeiDou Navigation Satellite System (BDS), paired with the self-developed intelligent dredging control systems. A single crew member can operate all navigation and operational tasks, achieving fully automated dredging operations.
