Abstract

Boilers experience frequent problems, such as scale formation, unstable steam pressure, incomplete combustion, and difficulty starting. Therefore, this study uses a quantitative method with the Failure Mode and Effect Analysis (FMEA) approach, which aims to determine maintenance and prevention to minimize these problems. This method determines the failure priority obtained from the Risk Priority Number (RPN) calculation based on assessment factors such as severity, frequency of occurrence, and the likelihood of failure being detected in each component. The results of these calculations indicate that the steam drum component falls into the highest category, with an RPN of 32. The other 12 components fall into the medium category: the feed water pump, electrode, photocell, nozzle, blower fan, solenoid valve, fuel pump, blowdown valve, main steam valve, scum valve, non-return valve, and gauge glass, with RPN values ranging from 12 to 24. Furthermore, the components in lowest category include the fuel filter, safety valve, and manometer, with RPN values ranging from 8 to 10. Therefore, the recommended improvements based on the FMEA results can be used as evaluation material to ensure the effectiveness of the improvements. Furthermore, regular boiler maintenance and monitoring are required, especially for components such as the steam drum, which requires additional routine maintenance schedules, repeated evaluations related to water treatment, and determining appropriate repairs for any steam drum failures.

Abstract

The Main Mover Diesel Engine or Main Engine on a ship is the main device responsible for moving the ship forward and backward. The diesel engine fuel system, which includes the Bosch Pump, is a critical component in maintaining the engine's performance by providing the fuel necessary for combustion and propulsion of the vessel. The injector, which is used to spray fuel into the engine cylinder, is an important part of the system that supports the efficient combustion process in the main engine. The method used is a quantitative method which includes the collection and analysis of numerical data. By conducting surveys, experiments, or secondary data analysis, researchers can find patterns or generalizations in a larger population. By using quantitative methods, it will be possible to determine the cause of the decrease in Bosch pump pressure on the ship MV.Tanto Bersinar. The analysis of running hoaurs of puncture valve on the fuel injection pump for cylinder 1-8 demonstrates that the wear of puncture valve especially in cylinder 2 with 4.970 hours approaching the planned maintenance system (PMS )limit of 5.000 hours significantly affects injection pressure stability ,combustion,quality ,and main engine officiency ,which can be restored throngh critical component replacement,inspections close to PMS and injection pump recalibration.
