Abstract

Generators are one of the important auxiliary aircraft needed on ships for power generation. During the operation of a diesel generator, continuous rotation occurs resulting in friction and erosion of the moving parts. The supporting factor for the smooth running of a diesel engine is a lubrication system that is supported by good lubricating oil quality, besides that it also needs to be supported by an adequate and good cooling system. The use of lubricants is one of the most important factors to ensure the performance of diesel engines. The lubricant is in charge of maintaining the condition of the engine so that it remains stable. This study aims to analyze the effect of using lubricating oil beyond the operating hours limit on engine heat. Furthermore, it also discusses steps to ensure diesel engine temperatures remain normal. This research was carried out during the practice of sailing on a ship for approximately one year. This study uses a descriptive quantitative research method. The primary data obtained directly utilizes observation methods, and documentation. Secondary data was obtained from existing articles and journals. The data analysis techniques used are descriptive analysis and inferential analysis. The results of this study show that the working hours of lubricating oil use have a significant influence on the increase in the temperature of diesel generator engines as evidenced by hypothesis tests on two engine units, namely AE1 and AE2. In the AE1 unit, a t-value of 18.467 with a significance of 0.000 was obtained, while in AE2 the t-value was 14.289 with a significance of 0.000. The significance value in both units is less than 0.05 so it can be concluded that the working hours of lubricated oil have a significant influence on the temperature of the genarato diesel engine on the ship.

Abstract

This study examines the variation of Heavy Fuel Oil (HFO) fuel consumption of the DAIHATSU 8DKM28e Main Engine at a stable performance condition of 620 RPM on the container ship MV. Tanto Keluarga, amidst the pressure of increasing fuel costs and regulations on maritime efficiency and decarbonization. The study uses a descriptive quantitative approach with a population of all main engine operational data during a certain voyage period and a sample of 5 sheets of Noon Report At Sea at a stable voyage condition in the open sea. The main instrument is the daily noon report that records the main engine speed, turbocharger speed, fuel rack, HFO consumption, and weather and sea conditions, plus ship technical documents and academic literature as secondary instruments. The data analysis technique used is descriptive quantitative analysis, with the calculation of averages, ranges, and trends as well as simple correlation examinations between performance parameters. The results show that HFO consumption varies up to approximately 1,005 liters per day at a relatively stable RPM, with a pattern closely related to changes in fuel rack, turbocharger speed, and sea state and weather conditions. The findings support that the main engine performance condition at 620 RPM is in dynamic equilibrium, so that fuel efficiency assessment needs to integrate internal and external factors simultaneously to support operational management, OPEX reduction, and compatibility with IMO EEXI and CII regulations.
