Case Study of Causes of the Ship’s Main Propulsion Failure

Analiza slucaja vjestacenja uzroka havarije na brodskom porivnom stroju

The paper focuses on the analysis of the cause of damage to the ship’s main propulsion “Caterpillar” C7. A full description of how the analysis was carried out is given in the paper. Any expertise, namely, is preceded by analyses of the authorised service provider’s expert evaluation reports. The engine defect detection started after the owner of the ship had reported on having problems with the increased temperature of the intake air, throbbing engine and increased smoke coming from the port engine. The inspection of the cylinder head and air cooler clearly indicated the origin of the main propulsion engine, CAT C7, failure. The damage was caused by the negligence of the service provider who failed to replace the air cooler Zn anode. Thus the galvanic current caused the deterioration of air cooler and mixing of seawater and air. This mixture entering the engine cylinders ultimately caused the damage to the engine.
