Once in service, Tongjun will be used in a variety of tasks such as domestic and international port and channel dredging, deep-sea sand extraction, land reclamation, deep-sea mining, trench excavation and backfilling, crushed stone bedding, and deep-sea pipeline laying. Dredging can be performed up to a maximum depth of 120 metres (390 feet).
The owner said she is also the first dredger anywhere in the world to receive the International Maritime Organisation’s intelligent dredging ship class notation.
During trials, the TSHD’s two 9,000kW dredge pumps achieved a discharge distance of 12 kilometres (7.5 miles) while her seakeeping ability was validated even under complex conditions.
