ANALISIS PENYEBAB PENURUNAN PERFORMA PADA FUEL OIL PURIFIER DI KAPAL MV. DREAM ANGEL

Abstract

Gidion Alvines Simbolon, 2025 "Analysis of the Causes of Degradation of Performance in Fuel Oil Purifiers on MV. DREAM ANGEL" This study was conducted to analyze the causes of the decline in performance in the fuel oil purifier on the MV. Dream Angel. The main problems found are the amount of fuel that comes out through the outlet of the sludge purifier and the decrease in liquid pressure in the fuel oil purifier system. These two problems cause the process of separating fuel from water and dirt to be suboptimal. This research method uses a qualitative approach with data collected during sea practice on MV. Dream Angel. Data analysis was carried out using fishbone diagrams. The results of the study concluded that the amount of fuel that came out of the sludge purifier outlet was caused by a mismatch between gravity disc and the specific gravity of the fuel. Meanwhile, the decrease in liquid pressure is caused by the clogging of the suction strainer in the feed pump and the occurrence of fuel overflow, To overcome this, the solution applied selects the gravity disc correctly according to the number, maintains the stability of the fuel temperature, and performs periodic maintenance and cleaning of the fuel oil purifier components. This research is expected to be an input for ship practitioners in improving the efficiency of fuel oil purifier performance.
