OPTIMALISASI KINERJA SISTEM PENDINGIN MESIN INDUK PADA KAPAL MT. STS SPB1 UNTUK MENINGKATKAN EFISIENSI OPERASIONAL

Abstract

A coolant is a substance that has the function of absorbing heat. This heat comes from the combustion process of fuel inside the cylinder as well as friction between metal components. The cooling systemconsists of several components that work in an integrated manner, including: coolant (cooler), freshwater circulation pump, seawater strainer, and seawater chest. Damage to one of these components can result in a decrease in the cooling effectiveness of the Main Engine. This research focuses on optimizing the maintenance of the cooling system in supporting the main engine's operation. This study was conducted on the ship MT. STS SPB1 for a period of three months. Data collection was carried out directly on the research object relevant to the topic discussed. The study results indicate that optimizing the maintenance of the cooling system contributes significantly to improving the reliability of the main engine and reducing the potential for failures that can cause losses. The implementation of this strategy is expected to achieve better operational efficiency, minimize emergency repair costs, and extend the equipment's lifespan.
