According to the new rules and regulations (New SOLAS), major safety critical systems are to be designed to be redundant, which is called ‘Redundancy Design’. This paper was to quantitatively analyze the degree of influence of the redundancy design applied to major safety critical systems using IMO’s FSA(formal Safety Assessment) method. For the purpose of this study, the diesel engine system, which is actually one of major safety critical systems, was dealt with FMEA, FTA and ETA technique. In addition, whether the redundancy was met or not was verified and the degree of safety, or redundancy, was represented in terms of reliability. In conclusion, the safety of propulsion systems is possibly assessed systematically by estimating the risk level in terms of frequency and fatality.
