In order to improve port Vessel Traffic Services (VTS) centers intelligence to realize intelligent monitoring and warning ships in the port. Used ship's position of time $\mathrm{t}_{\mathrm{k}-3}, \mathrm{t}_{\mathrm{k}-2},\mathrm{t}_{\mathrm{k}-1}$ and the time interval between $\mathrm{t}_{\mathrm{k}}$ and $\mathrm{t}_{\mathrm{k}-1}$ as input vector, the ship's position of time $\mathrm{t}_{\mathrm{k}}$ as output vector. Built a BP neural network based on irregular time series. Select the Automatic Identification System (AIS) data which a ship navigated in the port of Tianjin within three months to train the network, select a voyage data of the ship sailing in the port to test the network. Test results showed that the model has a high accuracy to forecast the track of ship in the port.
