For the failure moments and the time between failures of the marine power plants fuel oil systems, an attempt of defining the failure distributions has been made. The analysis was based on the observations of the failure of marine power plants fuel oil systems elements. Due to the character of the statistical data, the analysis deals only with relatively simple distributions, most frequently used in the reliability theory. 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. Data on their failures refer to the fuel oil system. The data on marine power plants failures were 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 were 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. The statistical analysis dealt with moments of the particular systems of consecutive failures and the length of time intervals between the objects of consecutive failures. In order to carry out the distribution estimation, the statistical package STATISTICA was used.
