Abstract
With the continued exploitation of the ocean by human extended to the deep sea, the traditional mooring system can not meet the operational requirements of ship positioning in the deep sea areas, therefore, dynamic positioning system came into being. The basic role of dynamic positioning is to maintain the position and heading of the marine structures, and providing a stable operating environment for the exploration of oil and gas proceed smoothly. The biggest characteristic of the marine environment is unpredictability and random, dynamic positioning is to be able to offset the effect of external low-frequency loads, and prevent the slow drift movement of the marine structures. Now, the dynamic positioning vessel has been put into application, and has a good practicality and economy, shows the broad prospects of the dynamic positioning applications.
