Abstract

The maritime transportation system plays a crucial role in international trade, with ships serving as the main means of transporting goods and passengers. One of the vital components in ship operations is the main engine, which requires a cooling system to maintain temperature stability. The jacket cooling fresh water system is the preferred choice because it can reduce the risks of corrosion and scale formation, which often occur in sea water-based cooling systems. The MV. Lumoso Karunia VIII's main engine fresh water cooling system overheated, reaching 90ºC and damaging the cylinder cover, which consequently disrupted operations. This study investigates the causes, effects, and preventative measures for this temperature spike in the engine's jacket cooling water system. A qualitative descriptive approach, using interviews and direct observation, was employed, with data analyzed using the SHEL model. Interviews were conducted with the chief engineer, second engineer, and fourth engineer. The factors causing overheating in temperature of jacket cooling fresh water in main engine include inadequate maintenance of the heat exchanger, blockage in the inlet that obstructs the flow of fresh water to the main engine, contamination in the cooling water, and dirt accumulation. The impact of the increased temperature in the jacket cooling fresh water of the main engine is engine overheating and financial losses. Efforts to prevent the overheating jacket cooling fresh water temperature in the main engine include regular maintenance and consistent inspections according to the Planned Maintenance System (PMS), cleaning of the heat exchanger and dirty expansion tank, as well as improving communication among the crew in managing the maintenance of the cooling system.

Abstract

The performance of the three-level air compressor on the ship has an important role in supporting the motion process, especially in supporting the main engine system. This study aims to analyze the factors that cause the decline in the performance of the three-level air compressor on board MV Oriental Jade. Descriptive qualitative research methods and a fishbone diagram approach, data was obtained through direct observation, interviews with crew members, and documentation studies. The research identified four main causes of air compressor performance degradation, namely narrowing of the air passage at the air radiator due to dirt accumulation, jamming of the spring concentric valve due to over running hours and dirt, and malfunction of the unloader valve. These problems caused the air pressure in the compressor to drop to 10 bar, far below the ship's optimal requirements. The impacts included delays in maneuvering, disruption of main engine operations, and a decrease in the ship's overall efficiency. This research provides recommendations in the form of increasing the frequency of air compressor maintenance, replacing components such as spring concentric valves and unloader valves that have passed the usage time limit, and routine cleaning of radiator water. In addition, the implementation of a better monitoring system can help detect potential damage early on. The findings are expected to serve as a practical guide for ship operators and fleet managers to improve the operational efficiency of the tri-level air compressor and reduce the risk of disruption to the ship's propulsion process.

Abstract

The MT Anggraini Excellent ship was sailing from Balikpapan to Samarinda when an alarm sounded during the watch. The main engine jacket cooling system indicated a high temperature of 88º C. Measures were taken to reduce the rpm (slowhead) and report the condition of the main engine. A request was made to stop the engine to inspect the cooling system. Using a qualitative descriptive method, data was collected through observations, temperature readings, pressure measurements, maintenance records, and interviews. The factors causing and the impacts of the seawater pump failure were identified. Maintenance and repair actions for the seawater pump were implemented to support the operation of the main engine. The collected data will be analyzed using the fishbone approach and processed with triangulation techniques to identify the factors causing the seawater pump electromotor failure and address overheating in the main engine. The research results indicate that the cause of bearing damage is exceeding the running hours limit of 2,750 hours, with an average insulation test on the electromotor of 10MΩ, and a decrease in pump pressure of 1.5 kg/cm² from the normal condition of 3 kg/cm² due to mechanical seal damage and a dirty seachest. The bearings, the three-phase 60 Hz 440 V 55 kW electric motor, and the mechanical seal were replaced. It is recommended to perform regular maintenance on the electric motor and pump in accordance with the PMS (Plan Maintenance System). Ensuring the availability of spare parts, electric motors, and seawater pumps is essential to maintain operational efficiency during maintenance.

Abstract

Maritime transportation plays a vital role in supporting Indonesia’s economy as an archipelagic nation. One of the crucial aspects of maintaining ship operations is the lubrication system of the main engine gearbox, which uses a Lo Cooler as an auxiliary device to cool the lubricating oil. This research employs a descriptive qualitative method through direct observation, interviews with the First Engineer and Chief Engineer (KKM), and documentation during sea practice on KM. Binaiya. The findings show that the main causes of leakage include cracked Lo Cooler tubes due to corrosion and sediment buildup, unstable lubricating oil pressure, elevated oil temperatures, and improper gasket installation. The handling efforts include regular maintenance, maintaining proper oil pressure and temperature, and repairing damaged tubes and gaskets. This research highlights the importance of routine inspections and lubrication system maintenance to prevent serious disruptions in ship operations.
