Abstract
The data, collected within the thirteen-year-long period, on the failures and maintenance activities when the propulsion system failed during the twenty-four hour navigation are taken from the engine-room log book. The significant components that usually failed during exploitation are defined by a delay analysis (of the registered failure cycles) and include the exhaust valve, the injection valve and the fuel pump. The most endangered component of the propulsion system is the exhaust valve having the highest failure rate. In order to increase the ship’s safety and her operational level, the authors suggest decreasing the failure impact on the significant components of the ship propulsion system which mostly failed during their exploitation. This can be achieved by choosing significant components of much higher quality and by using a better maintenance procedure that is by applying an adequate maintenance concept.
