Abstract
The cooling system on the main engine is one of the important parts of a ship that requires sufficient attention, because the smooth operation of the ship is very dependent on the work of the main engine, so that the main engine components are maintained from stress due to heat, the heat that arises must be controlled. This situation can be overcome by circulating the cooling medium with constant pressure to all components of the main engine such as cylinder jacket cooling, cylinder head, and injectors. This system must be a supervision for the engine crew so that the coolant flow is always smooth. For that we need a tool or aircraft called a cooler which functions to lower the temperature of a liquid or air from a high temperature to a lower temperature with the help of a cooling material, namely water or air, a system consisting of pipes, pumps, and cooling media. . From the usefulness of the cooler, there are several kinds, one of which is the plate cooler. In this study, researchers carried out land practice in KN. SAR Sadewa 231, writer found a problem / obstacle in the main engine's fresh water cooling system. The problem is the blockage of the seawater filter by dirt or mud and shells, as well as damage to the pump impeller caused by corrosion and leakage in the plate cooler. The results of this land practice are cleaning the seawater filter from dirt or mud and shells, replacing the damaged pump impeller with a new one, and repairing the leaky plate cooler. Seeing the incident above the fresh water system as the main engine cooling on the ship, it is very necessary to maintain and carry out routine and periodic maintenance in order to support the operation of the main engine on the ship. Keywords: Cooling System, Performance, Maintenance. .
