The methods of traditional passage planning are very complicated, and inconvenient. On the basis of analyzing the factors that influencing the passage planning in detail, the thesis gives the software in complementing method of the support system of passage planning including the shortest passage, the storage of bunkers, the selecting of charts, the mathematics model and algorithm of the draughts , tide height, and height above the water of any anticipated position.By this software, we can easily get the geographic position of the port, the routing chart, the shortest range, navigating time, estimated time to arrive, the number of selected chart, the relevant information of port, and the passage etc .The software can apply on the vessels to a great degree. It can provide advanced passage before dispatch, and supply relevant information for ships which navigate along this passage during its navigation. So it has actual significance to the safe navigation of ships.
