Comprehensive Maritime Formal Safety Assessment (MFSA) methodology is applied in marine diesel engine of a ship that is used in offshore environment to improve engine performance by reduction, prevention and mitigation of risk associated with its operation. The research focused on risk of crankcase explosion of the diesel engine, high pressure fuel line bursting, turbo charger explosion, suffocation from asphyxiating gases, burns, exposure to noise, vibration and explosions and fires in the exhaust manifold, which are estimated using expert engineering judgement. Possible ways of risk reduction and prevention that can ensure best output of the marine diesel engine are revealed, together with cost implications. Most preferred ways for the risk reduction and operational efficiency of marine diesel engine is recommended.
