Study on costal intelligent navigation system

The safety and economy of ship transportation is always an important issue in the shipping worlds. Due to complex natural conditions, relatively narrow navigable range and high traffic density, coastal navigation is usually not only an accident-prone area but also the low shipping efficiency. Therefore, an intelligent navigation system for coastal sailing based on numerical forecasting of environmental factors and simulation of ship´s motion is put forward. Take the effects of tidal current as an example, the construction and realization approach of the system is discussed. In view of tow key problems of system implementation, the tidal current distribution in coastal waters is successfully predicted by using POM, and the simulation of ship´s motion in the real-time tidal current fields was conducted based on MMG. The results show that this method of navigation system is feasible.
