Ship collision research is always a hot issue in the area of navigational safety or maritime traffic safety. This paper introduces a simulation technology applying ship maneuvering simulator to simulate collision process, which is currently an important technical method used in maritime accident evaluation and analysis. Firstly,using simulation technology, the ship collision process is real-time dynamically simulated and analyzed through ship collision accident analysis software (ship collision analysis system 2.0). The result has important reference value to the driver and the captain, and provides a new way for the maritime security supervisor organization to investigate and deal with ship collision accidents .
