Sažetak
Marine engine crankcase explosion except engine damage, in extreme cases, often results in serious injuries and deaths of crew members of the ship's engine room and the finaly with total loss of the ship. The biggest disaster of the ship engine crankcase explosion occured in the case of m / b "Reina del Pacifico" on 11th september 1947 when 28 people were killed and 23 wounded (Woodyard, 2009). Fortunately, in most cases the damage is limited to the engine, however, the danger of the big explosion engine crankcase is especially present if, in the case of explosions, oil mist burn out the engine crankcase, which can cause serious damage in the engine room especially at electric installations and devices. This paper describes the causes and consequences of the explosion in the engine crankcase as well as preventive measures for prevention of crankcase explosions that must be carried out during regular maintenance of marine engines. It also describes the safety systems to prevent the engine crankcase explosion, with special reference to research the world's leading marine engine manufacturer MAN B&W in the development of new methods of safety system to prevent crankcase explosion of marine propulsion engines based on water mist injection in supply line of the engine lubricating oil. The application mentioned methods for large two-stroke slow speed marine propulsion engines is described. 1
