Abstract

Muhammad Nuruddin, 2017, NIT : 50135032, T, “Analysis of Corrosion Occurrence In F.W Cooler Motor Diesel Generator MV. Hanjin Port Kelang”, Technical Thesis, Diploma IV progam, Merchant Marine Polythecnic Semarang. Material Adviser (I): H. Suwondo , M.M , M.Mar.E. Methodologi and Writing Adviser (II): Irma Shinta Dewi, M. Pd. F.W Coller is an auxiliary aircraft used to cool a diesel engine because of the combustion of fuel inside the cylinder. While the cooling or cooler engine is divided into 2 types, namely closed cooling system and open cooling system. The importance of diesel engined cooling systems requires the need for regular maintenance or daily maintenance. However, due to not the occurrence of less than optimal treatment resulting in the emergence of corrosion on the main cooler. Therefore it is necessary to analyze the occurrence of corrosion on f.w cooler diesel generator motor on MV. Hanjin Port Kelang. The purpose of this study is, to determine the cause of corrosion in f.w cooler contained in diesel generator MV. Hanjin Port Kelang, besides that research aims to know how to care for cooling water cooling motor system in order to work better. This research is descriptive qualitative by using technique of data analysis of Urgency, Seriousness, Growth (USG) that is one tool to arrange order of priority of issue to be solved, how to determine the level of gravity, seriousness, and issue development by determining scale value 1 to 5 or 1 to 10 issues that have the highest total score is a priority issue. In addition, data collection was done by interviewing, observation by observing at the time of overhaul on the ship MV. Hanjin Port Kelang. The result of the research shows that there are 4 factors that cause corrosion and its effect to the smooth operation of the ship is the lack of maintenance of the cooler cooler system in the generator, the cooler condition in the generator is not good, the aznya zink anode on the cooler, the influx of seawater flow in the cooling system. Of the four factors the lack of maintenance of cooler cooling system into the main cause of corrosion. Besides how to care for cooling water system to always work well can also have an effect on the prevention of corrosion by always doing water test on the water circulating in the cooler it will be found acidity levels that can corrode the cooler itself.
