Abstract:
This research aims to analyze and optimize the performance of the main engine cooling
system on the MT. Sumber Cahaya 68 vessel to support smooth engine operations. The
cooling system plays a crucial role in maintaining engine temperature within the normal
operating range. However, issues such as blockages in the heat exchanger and corrosion
in the seawater pump have been identified, leading to decreased cooling efficiency. This
study employs a qualitative descriptive method through direct observation during
onboard training, interviews with engine officers, literature review, and documentation.
The findings indicate that blockages in the heat exchanger were caused by the
accumulation of sludge and marine debris, while corrosion in the pump resulted from
the deterioration of zinc anodes and inadequate routine maintenance. Solutions
implemented include cleaning components and conducting regular maintenance,
including replacing damaged parts. Optimizing the cooling system has proven effective
in stabilizing engine temperatures and preventing severe damage. This study is expected
to serve as a practical reference for ship crews in managing cooling system issues more
effectively.
