As next-generation, high-end, intelligent, and environmentally friendly grab suction dredgers, the "Tongjun" and "Junguang" are capable of exceptional performance, including strong soil penetration, deep dredging, long-distance transport, and extended blowing capabilities. They are expected to be widely used in port and waterway dredging, deep-sea sand extraction, land reclamation, deep-sea mining, trench excavation and backfilling, gravel bed construction, and deep-sea pipeline laying.

Both dredgers are designed to operate in waves and winds of up to grade eight. With the self-developed intelligent dredging control systems, one crew member is able to handle all navigation and operational tasks. Under normal working conditions, the dredgers can fill their mud holds completely within 90 minutes.

Once these two dredgers are put into operation, they will further optimize China's dredging fleet, accelerating the professionalization, specialization, and internationalization of the nation's dredging capabilities, said a staff member of CCCC Dredging (Group) Co Ltd.
