The paper presents a method of bridge safety evaluation with respect to possible collision with passing ships. The method is a combination of three separate methods: real time ship manoeuvring simulation and Monte Carlo method combined with analytical method. The first method is used to determine the probability density function of ship position during passage near the bridge piers and distributions of ship speed and courses. During simulations, human operators are employed and thus the method takes into account human reliability. Monte Carlo method is used in last step for extending the results over the bridge lifetime and possible meteorological conditions during bridge operation. It applies the previously determined distributions of ships positions that allow assessing probabilities of collision with bridge pier. The calculation of ships collision load and energy that are necessary for further consequence analysis is made on the base of distribution of ship speed obtained in simulations.
