Sažetak
Marine diesel engine is a complex multivariable nonlinear dynamic system. Its basic structure consists of interdependent and connected subsystems with a large number of different components. Faults can appear in any component of the system. Therefore, for improving reliability and marine engine systems safety fault diagnosis methods are more and more important. This paper gives an especial review on interference diagnosis methods in a function of timely localization and isolation of faults. Fault tree analysis shows all causes of heavy fuel oil separator incorrect operation. Influence of impurities in fuel oil on environment and possible fuel oil system faults as a direct consequence of separator incorrect operation has been analyzed. Fuel oil systems faults have been simulated using Full Mission Engine Room simulator Kongsberg Norcontrol. Symptom behavior in time has been presented by binary matrix. Table analysis has been conducted by fuzzy facts. Results obtained through simulation point to the importance of fault diagnosis for the timely prevention of the occurrence of faults, thereby contributing to the reliability and availability of marine engine systems.
