Abstract:
Syaelindra, Rey. 2025. "Analysis of the Cause of the Increase in the Cooling
Temperature of the Main Engine on the MT. Prima XP"
This study aims to identify the cause of the increase in the cooling temperature of the
main engine in the MT ship. Prima XP. The cooling system on the main engine is a vital
component in maintaining optimal operating temperatures to support engine performance
during shipping. Based on the author's sea practical experience, it was found that a
disturbance in the cooling system was characterized by an increase in the temperature of
the freshwater cooler from 80°C to 86°C, thus triggering the alarm and slowing down of
the main engine. This research uses a qualitative method with a case study and problem
solving approach, as well as data collection techniques through observation, interviews,
and documentation.
The results of the study show that the main cause of the increase in cooling temperature
is the dirty seawater filter in the sea chest and the occurrence of corrosion in the cooling
plate of the central cooler. Both conditions inhibit heat exchange efficiency, causing the
cooling system to not work optimally. Efforts to solve problems are carried out through
routine maintenance, cleaning, and periodic monitoring of cooling parameters. This
research makes a practical contribution in improving technical understanding and
becomes a reference for engine officers in maintaining the reliability of the ship's cooling
system.
