Abstract

This study examines the factors causing the increase in the fresh water cooler (FWC) temperature of the main engine on the KMP Port Link III. The FWC cooling system plays a crucial role in maintaining a stable and efficient engine operating temperature. However, temperature increases exceeding the optimal operating limit can pose a risk of serious engine damage. The objective of this study was to identify the primary causes of the FWC temperature increase and evaluate the effectiveness of maintenance measures in reducing system temperature. Data collection was carried out through direct onboard observation, recording temperature data before and after maintenance, and technical analysis of cooling system components. Data were obtained through temperature measurements at the FWC outlet and engine cylinders, as well as inspections of the sea chest, strainer, freshwater pump, and coolant capillary tube. The results showed that blockages in the strainer and capillary tube, decreased pump pressure, and insufficient cooling water volume were the primary factors causing the freshwater temperature to rise to 80 ℃. After maintenance measures, such as cleaning and refilling the cooling water, the temperature was successfully reduced to the normal range of 51–54 ℃. This study emphasizes the importance of routine and systematic cooling system maintenance to maintain optimal main engine performance and prevent operational disruptions.
