Modern information technology provides the assumptions and wide opportunities for recording monitoring data in real time. This makes it possible to install various monitoring systems in important facilities, such as a seaport. However, when processing the data obtained by the monitoring system, the problem of their reliability always arises. In this research paper, an attempt is made to formulate and solve the probability problem of the reliability of the received measurement data of the monitoring system. The long-term data of measurements used for this research work are obtained by measuring the displacements of selected characteristic points of the Klaipeda seaport pier in the presence of the air and water temperature and wind speed changes. All measurement results are obtained using a modern geodetic instrument in the process of diagnostics of the geometrical position of the pier structures built at Klaipeda seaport. The most important attention is paid to the influence of the air temperature and wind speed on the reliability analysis of geometric position measurement results using mathematical statistics methods. The analysis of the obtained results for deviations of the crack width of individual points in the Southern pier allowed to create special algorithms for data processing of monitoring systems, which could be used for improving the global maintenance of seaport piers.
