Strategi Pemeliharaan Berdasarkan Failure Mode Effect and Critically Analysis (FMECA) dan Reliability Centered Maintenance (RCM) Pada Cooling System Mesin Diesel Daihatsu DK28E MV. Meratus Kapuas

Abstract

The water cooling system on ships plays a vital role in maintaining the stability of the main engine temperature, ensuring that the engine operates optimally. Failures in this system often result in reduced performance, progressive damage, and the risk of container delivery delays. Therefore, a method is required to reduce the risk of failures in water cooling system components, and the method applied in this study is Failure Mode, Effects, and Criticality Analysis (FMECA). This research focuses on developing a maintenance strategy for the cooling system of the Daihatsu DK28E diesel engine installed on MV. Meratus Kapuas. The study conducted through systematic data collection on operational history, failure records, and technical specifications, followed by the identification of failure modes, their effects, and criticality ranking to determine the most critical components. The risk analysis showed that several components such as fresh water standby pump, main sea water pump, lubricating oil cooler, intercooler, gate valve, swing type stop check valve, globe type stop check valve, butterfly valve were categorized as High risk, while components such as the fresh water cooler, filter sea chest,  and fresh water temperature control valve were classified as Moderate, and expansion tank, globe valve, engine drive fresh water pump, and lubricating oil cooler gearbox as Low. Based on these findings, appropriate maintenance tasks such as on-condition task, scheduled restoration task, and discard task intervals were recommended.
