The notion of a seasonal pattern of cruise ships has been used frequently, but very few authors have analysed all the features of this pattern. This article adds some new insights on this topic by analysing cruise ship activity in the three largest ports on the east coast of Adriatic Sea in 2017 and 2018. The article presents an analysis of cruise ship arrivals at the ports and compares the analysis to the established pattern in the Mediterranean, revealing the nature of the seasonal pattern for the ports analysed. In addition, two further analyses were carried out, firstly the analysis of ship size, which determines new characteristics of the seasonal pattern. The second additional analysis considered the duration of ship visit during different times of the year and determined another pattern characteristic.

The paper presents an attempt to develop better and cheaper methodology for evaluation of the quality of the ships’ computerized Planned Maintenance System databases. A concept for the better methodology has been developed following many times verified rule that faster and cheaper is better. The concept of the methodology has been checked in operation, tested on four different databases. Results of the evaluation performed by the concept are compared with an expert evaluation using old, verified methodology, performed on same databases. Comparison valuated the concept, bringing the verdict if it is functioning or not, showing that the old and verified rule is not functioning every time.
