Analisa Reliability Akibat Modufikasi Jumlah Power Pack Pada System Hydraulic Permesinan Geladak Pada MV “Sirena”

Abstract

Hydraulic System MV " Sirena" representing one of the system which vital enough to fluency operation of ship beside other supporter system. Failure of hydraulic System in operating to earn because of failing of one of the component at the system. May this system do not operate properly and ship cannot sail, so that will generate many loss Research location in PT. Jasa Marina Indah Semarang ( unit 2). Yos Sudarso street, Bandarharjo Semarang with obyek research of hydraulic system as activator machinery of deck at MV " Sirena". Aim of this research for hydraulic system evaluation by using approach base on reliability. Some steps which doing into effect in this research are data collecting, evaluation and desain with approach qualitative. Approach qualitative use Failure Mode and Effect Analysis (FMEA) and Fault Tree Analysis (FTA). Result of research indicate that critical level ( severity) and rate failure hydraulic systems not so seen its at Strainer, and Return Filter. Keyword : reliability, hydraulic, Power Pack
