In order to benefit the long-term maintenance dredging of the Yangtze Estuary deepwater channel,we carried out a study on the application of the trailing suction hopper dredger (TSHD) loading barge technology.Based on the in-situ simulation tests and the designed capabilities of the specified TSHD and barge, we illuminate the working process, working period and efficiency, operation conditions and economic benefit. It is concluded that the TSHD loading barge technology can be applied in the Yangtze estuary. Meanwhile, some suggestions are put forward.
