In the paper a number of various types of vessels of power plant steam system failures have been analyzed with regard to the general population they come from. For the purpose of the analysis the Kruskal . Wallis rank sum test and Kruskal . Wallis ANOVA rank test from the statistical packet STATISTICA 8.0 have been used. The analysis was based on the observations of the failure of marine power plants steam systems elements. Failures to the marine power plant systems of 10 ships owned by the Polish Steamship Company of Szczecin was the subject of a statistical data analysis. All the ships differed in respect to their place and time of construction as well as their technical parameters. The data on marine power plants failures was collected in similar conditions, that is, they were supplied by an engine crew member working in the marine power plant. The data on the failures of particular marine power plant systems was obtained accordingly to the test schedule [N, W, T], which means that N renewable objects were the subject of the test within the time T. Since the recovery time of the damaged system appeared negligibly short, when compared to the time of the test, it was assumed that consecutive recoveries overlap the failure moments.
