Dual Fuel Diesel Engine (Mesin Bahan Bakar Ganda) merupakan mesin denganpemanfaatan dua bahan bakar dalam proses pembakarannya untuk memperoleh tenaga kerjapada mesin. Jenis bahan bakar yang digunakan meliputi bahan bakar Methane Gas (CH4)dan MGO (Marine Gas Oil). Methane (CH4) dihasilkan dari Vapour Cargo Tank LNG(Liquified Natural Gas). Tujuan dari penelitian ini adalah untuk mengetahui apa sajapenyebab tingginya suhu gas buang terhadap kinerja Dual Fuel Diesel Engine di MV.Tangguh Palung dengan menggunakan metode analisis data Fault Tree Analysis. Darianalisis data penelitian di hasilkan beberapa rumusan masalah yaitu, faktor-faktor yangdapat menyebabkan tingginya suhu gas buang pada Dual Fuel Diesel Engine adalahkurangnya suplai udara pembakaran dalam ruang pembakaran mesin, komposisipembakaran yang tidak sesuai antara bahan bakar minyak dan gas, serta suhu Engine Roomyang terlalu panas. Dampak yang di timbulkan adalah kerusakan pada komponen-komponenpermesinan dan penurunan kinerja dari Dual Fuel Diesel Engine. Untuk mengatasipenurunan kerja pada Dual Fuel Diesel Engine adalah dengan melaksanakan perawatan danperbaikan pada setiap komponen permesinan yang mengalami masalah dan kerusakan sesuaidengan Running Hours dan Instruction Manual Book.

Maintenance Plan

The reliability of marine propulsion systems depends on the reliability of several sub-systems of a diesel engine. The scavenge air system is one of the crucial sub-systems of the marine engine with a turbocharger as an essential component. In this paper, the failures of a turbocharger are analyzed through the fault tree analysis (FTA) method to estimate the reliability of the system and to predict the cause of failures. The quantitative method is used for assessing the probability of faults occurring in the turbocharger system. The main failures of a scavenge air sub-system, such as air filter blockage, compressor fouling, turbine fouling (exhaust side), cooler tube blockage and cooler air side blockage, are simulated on a Wärtsilä-Transas engine simulator for a marine two-stroke diesel engine. The results obtained through the simulation can provide improvement in the maintenance plan, reliability of the propulsion system and optimization of turbocharger operation during exploitation time.

This paper is based on the application of the root cause analysis principle of diesel engine injector failure in diesels Haditha station. The maintenance of the diesel engine injector contains many problems that lead to the injector stopping; several reasons lead to such Problems. Fault tree analysis (FTA) is one of the most widely used methods in the industrial sector to perform reliability analysis of complex engineering systems. A fault tree is a logical representation of the relationship of primary/basic events that lead to a given undesirable event (i.e., top event). This research aims to present the (FTA) technology and how to use it in analyzing the causes of problems that lead to the injector stop working, and how to calculate the probability of occurrence of such problems. Implementation of FTA based on the probabilities of the causes under the top event and canalization lead to the calculated probability value (0.80). The plant management can define a specific plan to reduce these problems, because failure of an important engine part (injector) with such a large value leads to long downtime hours compared to operating hours.
