The importance of the task of accumulating information on failures of elements and assemblies of modem ship diesel engines in the problem of increasing their functional reliability (FN) at the final stage of the life cycle (LC) - the stage of technical operation (ТЕ) is shown. Statistical researches of oil tankers main diesel engines cylinder units’ elements failures are revealed in the article. Analysis of malfunctions and its causes while operations are described. Levels of functional reliability of main diesel engines cylinder units’ elements are reviewed. Indexes of statistical research are offered as evaluation signs of functional reliability and same have to be included into info-statistical database which are corresponds to final “lifetime” stage of technical operation.
