According to CCTV News, two ultra-large trailing suction hopper dredgers independently designed, developed, and built in China will be launched in Qidong, Jiangsu Province on August 26. Dredgers, also known as dredging vessels, are commonly used for port desilting, channel excavation, and land reclamation.
The two ultra-large trailing suction hopper dredgers, the Tongjun and Junguang, are each approximately 198 meters in length, with a maximum dredging depth of 120 meters. Their maximum tank capacity is equivalent to the volume of 18 standard swimming pools, making them the largest in Asia and world-leading in loading efficiency.
After the two vessels are launched, they will undergo installation of dredging equipment and intelligent control systems. They are scheduled to undergo sea trials and be commissioned by the end of this year.
After delivery, the two vessels will be widely used in domestic and international port and shipping dredging, deep-sea sand extraction, land reclamation, deep-sea mining, trench excavation and backfilling, crushed stone bedding, and deep-sea pipeline laying.
