A crankcase explosion relief valve (ERV) is installed to prevent accidents caused by explosions inside the crankcase of marine engines. Engine manufacturers demand lower prices of parts due to declining shipbuilding and engine prices. PROSAVE developed an ERV for a 30% cost saving. The developed ERV is the largest product to be installed in marine diesel engines. In this study, structural analysis was conducted on the ERV, and the radial displacement and von Mises stress were within the allowable range. An explosion test was performed according to criteria set by the International Association of Classification Societies (IACS) to evaluate the performance of the ERV. The test results show that the difference between the reference pressure and explosion pressure satisfies the IACS reference value, and the ERV was sufficiently airtight after the explosion. Flames did not spread outside during the explosion, the temperature rise in the flame arrester was acceptable, and there was no damage to the components. According to the performance test results, the ERV developed by PROSAVE satisfied the criteria required by the IACS, and the ERV showed a reliable performance at a 30% production cost saving.
