Motion Response Analysis of Mining Vessel with Dynamic Positioning in High Sea Conditions |
| |
| Abstract: | The motion response of deep sea mining vessel with DP is studied and its motion response behaviors are analyzed in high sea
condition. For the dynamic positioning system composed of six side propellers, considering the high sea condition and two typical
operational conditions of load full and ballast, the control parameters of the side thrust system are adjusted, the thrust force is optimized and
direction of thrust is adjusted in the real time based on the conditions of minimum thrust and minimum motion, as well as the control
algorithm of Kalman filter and linear quadratic optimal theory is applied, the time history response of motion and thrust for mining vessel in
high sea condition are calculated and the motion characteristics are studied. The research results show that, the wave incidence angle and
thrust size that can position in high sea condition are obtained for load full and ballast of deep sea mining vessel, the adaptability of the
dynamic positioning system of mining vessel is determined in high sea condition, the positioning ability of the mining vessel is evaluated
reasonably in high sea condition. |
