Dynamic positioning refers to a system to automatically maintain position and heading of a ship or floating marine structure by using its propellers and thrusters. This allows operations at sea where mooring or anchoring is not feasible due to deep water and congestion on the sea bottom. It is much used in the offshore industry.


The main components of typical dynamic positioning (DP) system are introduced briefly for marine operations. The basic principle and functions of DP system are presented. In the ice-covered area, there may exist a lot of challenges regarding DP operations in ice. The development of DP technology applied to marine operations in the ice-covered sea is presented. Finally, experiences regarding realistic marine operation is collected to give some lessons which are useful to...
