China Communications Construction Company (CCCC) Tianjin Dredging Co., Ltd. on Tuesday announced the successful launch of the "Tongjun" dredger, a 35,000 cubic meter capacity, ultra-large, self-propelled grab suction dredger.
Another dredger, the "Junguang," with the same capacity and belonging to the CCCC Guangzhou Dredging Co., Ltd. was also launched on the same day.
Both dredgers are designed with a length of 198 meters, a beam of 38.5 meters, and a depth of 18 meters. They can dredge up to a maximum depth of 120 meters.
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.
