The paper presents new method of ship passage under the bridge safety evaluation. The method is combination of photogrammetric real time measurements and simulation method. The photogrammetric method is applied in purpose to obtain real data of maneuvering ships and barges and validation of simulation data. The results achieved by presented method can be applied for evaluation of safety of existing and modernized bridges in aspect of collision with passing ships. The method can be also used for determination of protection guide fenders for minimizing the possible ship's impact and increase the bridge construction safety. The paper presents case study of method application aimed to find optimal shape of guide fenders in Railway Bridge located in Szczecin.
