ANALISA KERUSAKAN PIN BEARING TERHADAP PENGOPERASIAN MESIN INDUK MV. ENERGY MIDAS

Rasula Ade Pratama, NIT : 51145325.T, 2018, "The Broken of Bearing Pin Analysis in Main Engine Usage at MV. Energy Midas", Diploma IV Program, Engineering Program, Politeknik Ilmu Pelayaran Semarang, Head of Community Service Development Center, Counselor I: H. Rahyono, SP.1, MM, M.Mar.E and Advisor II: Capt. Firdaus Sitepu, S.ST., M.Si. Various shipping companies are improving services to prioritize good service. If the main engine in the ship experienced a broken bearing pin will have an impact on the decreasing timeliness of the ship operation, therefore always performs maintenance and repair of parts and spare parts, so it will generate a ship with engine condition that has more operational value. This study aims to analyze the factors causing broken of bearing pin in main engine of MV. Energy Midas, to analyze the effect caused to the main engine in case of broken of bearing pin in main engine of MV. Energy Midas and to analyze strategies / efforts in dealing with the broken of bearing pin in main engine of MV. Energy Midas. The research used Fishbone and Fault Tree Analysis method by using verbal data and qualitative data. Called with Fishbone because it is looks like a fishbone with the head toward the right side. This diagram shows cause and effect of a problem with multiple causes. Fault Tree Analysis is an effective method used to find the core of a problem by confirming that the cause is not came from single origin. Fault Tree Analysis identified the relation between causes and show it in form of a fault tree that used simple logic gate. Factors that causing the broken of bearing pin in main engine of MV. Energy Midas due to leakage of bushing telescopic pipe, a crack of lock bearing pins and loose of crosshead bearings, sagging bolt locking crosshead bearings. The broke pin will have an impact on the components and system of the main engine suffered severe damage. Efforts / strategies to overcome the broken of bearing pin in main engine of MV. Energy Midas ie Engineers must make a change of telescopic pipe bushing, checking crosshead bolt lock with hammer test then binding with hydrolic jack and perform special training from maker MAN B&W as scheduled.
