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.

Analysis of overflow loss of trail suction dredger;

This paper introduces the draghead technique development of trail suction dredger, analyzes the structure whose drag principle adapts the working situation and presents advices on how to improve the dredging ability, selection and use of the draghead.
