Damage to the diesel engine turbocharge with a capacity of 11.3 MW which has been operating for around 18 years has caused a halt in electricity supply to one of the regions in eastern Indonesia. The data before the damage occurred was that the generator engine was operating at a load of 10.2 MW, with the engine running hour being 66,930.2 (hours), the exhaust temperature before and after the turbocharge was 514 ° C / 342 ° C and the speed on the turbocharge was 16,637 rpm, where the data is still within the limits of normal operation. After dismantling the turbocharge, it was found that there were damage to the components of the turbocharge, namely: turbine blade, shaft, ring nozzle, and others. To ensure such damage, a number of tests and materials were tested specifically for the turbine blade. The testing method is the methallografy test, chemical composition and hardnes test. The results of the analysis indicated that the turbine blade material was damaged quickly or instantly, so it was believed that the material was damaged because of the impact of foreign material entering the turbocharge system. The total loss of damage to this turbocharge is IDR 10,663,278,512 (Repair and Loss of Profit Costs).
