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.
