1、Based on the sequential quadratic programming method, a thrust allocation for the trailing suction hopper dredger was presented.

2、The paper intends to prove that the intact stability of a hopper dredger in part load condition is better than that in full load condition.

3、These will include trailing suction hopper dredgers, cutter suction dredgers, anchor handling tugs and heavy transport vessels.

4、Improving the working character and the efficiency of trailing suction hopper dredgers will greatly increase the production, save power and bring more interests for dredging industry.
