Analysis of Influential Exhaust Valve Damage On the Exhaust Gas Temperature of the Main Engine on the MT Ship. Bintang Mas Hsb 2

Abstract

This study aims to analyze exhaust valve damage that affects the exhaust gas temperature of the main engine, focusing on the cause of the damage, its impact on the main engine, and preventive measures. Data were obtained through observation methods during marine practice for 12 months and literature studies related to the literature on ship engine engineering. The results show that wear on the spindle and seat rings is the main cause of damage, which can temporarily stop engine operation and reduce the efficiency of the vessel. Qualitative descriptive analysis was used to understand the relationship between exhaust valve failure and change in exhaust gas temperature. This research provides theoretical contributions in the management of ship engines as well as practical recommendations in the form of exhaust valve maintenance and repair procedures, including the implementation of planned maintenance systems. With the right implementation, these results are expected to improve the reliability and operational efficiency of ships, minimize downtime, and ensure smooth shipping activities.
