Analisis Dampak dan Cara Mengatasi Kegagalan Sistem Pendinginan pada Auxiliary Engine di MV. Federal Kibune

Abstract

Auxiliary engines are a category of internal combustion engines in which air is compressed to a temperature sufficient to burn fuel sprayed into the combustion chamber. A faulty cooling system can cause Auxiliary engine No. 1 MV. Federal Kibune is not working optimally. The purpose of this study is to determine the causes and impacts caused and efforts made to overcome engine failure. This research uses qualitative descriptive research method with SHEL (Software, Hardware, Environment and Liveware) method research design. Data collection techniques through interviews and direct observation. The results of this study stated that the factors causing the failure of the cooling system were the non-implementation of appropriate maintenance of the cooling freshwater pump (high-temperature water) components, the availability of spare parts and incomplete instruction manual manuals, the wear of impeller and shaft threads, weakening construction, loss of impeller and shaft traction, uncirculated temperature, lack of fresh water treatment, lack of monitoring, and improper operation according to procedures. The impact is damage to the cooling fresh water pump, limited handling, overheating, damage to the impeller and shaft cooling fresh water pump, obstructed loading and unloading, increased temperature, changes in freshwater quality, limited problem detection, and improper operation according to procedures. Efforts are made to carry out the maintenance system (PMS) plan, conduct safety meetings, check parameters, replace impellers and shafts, gradually warm up and cool, check fresh water coolant, provide instructions to the engine crew, and provide training on engine crew operations.
