Abstract

The diesel engine is a vital component that serves as the ship's main propulsion system. This engine plays a crucial role in the efficiency and operational stability of the ship. One of the important parts of a diesel engine is the governor, which functions to regulate the engine's rotational speed to keep it stable. Problems with the governor can cause engine speed instability, leading to operational issues, reduced fuel efficiency, and a higher risk of damage. The study uses observational methods to identify the main causes of engine speed instability due to governor failure. Basic data include measurements and observations, maintenance history, and records of past failures. Observations on engine speed instability caused by governor failure focus on electrical issues, material wear, and extreme temperatures. This research emphasizes the importance of good and routine maintenance for the governor. Maintenance includes regular inspections, electrical maintenance, and the replacement of worn components. The research results are expected to provide practical recommendations for ship technicians to improve maintenance activities and address diesel engine speed instability issues. Implementing the findings of this research is expected to enhance the overall safety and operational efficiency of the ship

Abstract

Ships are water transportation tools used in the sea, rivers, or lakes for various purposes such as transporting goods, passengers, and fishing. Ships generally use power from engines, such as diesel engines to drive the propellers that propel the ship in the water. The problem experienced by the author when carrying out sea practice for one year (July 2023 - July 2024), on the main engine of the MT. Transko Bima ship is the entry of coolant into the cylinder, which can have a negative impact on the performance of the main engine. Therefore, this study aims to analyze the causes of the entry of coolant into the main engine cylinder on the MT. Transko Bima ship. The research method used is a case study with a descriptive qualitative approach. Data were obtained through direct observation, interviews with engine crews, literature studies and documentation during sea practice on the MT. Transko Bima ship. The results of the study showed that damage to the exhaust valve seat was the main cause of the entry of coolant into the cylinder. This problem has an impact on the engine experiencing corrosion, water hammer, and can cause further damage if not handled immediately. Repair efforts include replacing damaged components and routine maintenance of the cooling system to prevent overheating. This research is expected to contribute to ship engine crews in handling similar problems and improving the reliability of ship operations.
