Overall design on a Lian Yungang 5000 m~3 drag suction dredger;

Dump door mounting for mud hold on drag suction dredger;

Estimation of dredging operation resistance of drag suction dredger;

Trailing suction hopper dredger plays an important role in growth and construction of port and waterway.

The paper expounds the major mathematical models that have been developed independently for trailing suction hopper dredgers to optimize their production and improve their working technology according to the changes of seabed.

After analyzing the dredging diesel updating for trailing suction hopper dredger that imported from abroad, this paper gives a demonstration of operation characteristics, application range, relevant technological problems and solvent of new machine type.

On type of all-electric propulsion plan for suction hopper dredger;

The classification of CCS has the trend to allow the suction hopper dredger to reduce its freeboard,while the intact stability should be calculated in terms of DR67 resolution.
