Dynamic positioning system of ship

With the developments of deep-sea technologies,the dynamic positioning system(DPS) has been widely applied in offshore project.The dynamically positioned system of a vessel is designed to accurately maintain the vessel's position and heading at a fixed location or a predetermined track for marine operation purposes by exclusively using active thrusters.In this paper,the development and application of the dynamic positioning(DP) system were investigated.The principle how the DP works was analyzed.The typical configurations of the foreign famous DPS were studied.The system restrictions,control strategy,control technology,and thrust allocation of DP were analyzed.It was pointed that the accuracy of dynamic positioning system depends on dynamic positioning control and measurement equipment.Based on the researches above,an approach to develop our own dynamic positioning system was presented.
