The paper presents the practical using of model for underkeel clearance evaluation. Real data from Maritime Office concerning ships which enter ports was used to analysis of results first probabilistic model of underkeel clearance and next integrated system. During analysis mean probability that underkeel clearance will be less than zero was determined for ports in Świnoujście, Szczecin and Police. Results of this analysis can be used for further research connected with integrated system for underkeel clearance calculation.

The paper is concerned with the analysis of under-keel clearance of ships based on real data from Szczecin Maritime Office. Using probabilistic method for UKC assessment give it possibility to create the distribution of under-keel clearance in several ship’s passages and in further step to determine the probability of ship’s grounding accident during the port approach. The results of using this type of model could be used in risk assessment of ships entering to the ports, therefore it is possible to used probabilistic model in Maritime Office employees’ everyday decision making practice. Research results present verification of probabilistic model, based on data from Vessel Traffic Service database and probability of touching the bottom during ships’ passages on Swinoujscie - Szczecin waterway. Moreover there are presented examples of these situations when entering to the port for analysed ships is not allowed according to the model.
