Modern information systems and technologies make it possible to store a large amount of data on transport-logistics processes. Using various mathematical algorithms and meth-ods of the data mining and machine learning, knowledge can be obtained and expressed as a behavioral model of the system. The process mining method is one of the relatively new methods and it is already widely used in different areas. Due to this method, one can simulate the whole process as it is and lately work with a valid re-flection of the actual operations. Theoretically, transport-logistics processes are an example of reg-ulated and structured processes. However, in practice, normative and descriptive models often have a lot of differences and such deviations cause bottlenecks in the workflow, and thus lead to temporal and financial losses. With the help of Process Mining algorithms, the actual process of ship entry processing at the oil terminal is represented as an undirected graph. The existing problems of port systems are marked, as well as the need to work with the actual process models. The possible options to optimize processes and, consequently, improve the competitiveness of the port were considered. The schemes of transport processes, in which sea port is involved, were presented. The place of the analysed processes in the overall process scheme is defined. The methods and documents involved in the process of creating the model were identified. Two received models of vessel’s treatment were reflected and the main results of the analysis were described, problems and possible solutions were listed.
