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.

Fire and explosion accidents occur frequently in tankers because they transport large quantities of dangerous cargo. To prevent fire and explosion accidents, it is necessary to analyze factors that cause accidents and their effects. In this study, factors that cause fire and explosion accidents were classified using the 4M disaster analysis method, and each factor’s effect on the accident was analyzed using fault tree analysis (FTA). First, the unsafe tank atmosphere environment was identified as a primary cause of fire and explosion accidents in tankers, and the underlying causes of these accidents were investigated. The probability of underlying causes leading to primary causes was derived using an expert survey. The results showed that management and media factors had a greater impact on the unsafe tank atmosphere environment than human factors. To prevent fire and explosion accidents, it is necessary to ensure sufficient working and resting times for seafarers and compliance with procedures and work guidelines. A generalization of the results of present and future studies will enable the identification of the cause and preventive measures for fire and explosion accidents in tankers. Furthermore, this will reduce accidents in tankers and contribute to future safety management measures of ships and companies.

Analytical Tools, Like Fault Tree Analysis, Have A Proven Track Record In The Aviation And Nuclear Industries. A Positive Tree Is Used To Insure That A Complex Engineered System Operates Correctly. A Negative Tree (Or Fault Tree) Is Used To Investigate Failures Of Complex Engineered Systems. Boeings Use Of Fault Tree Analysis To Investigate The Apollo Launch Pad Fire In 1967 Brought National Attention To The Technique. The 2002 Edition Of Nfpa 921, Guide For Fire And Explosion Investigations, Contains A New Chapter Entitled Failure Analysis And Analytical Tools. That Chapter Addresses Fault Tree Analysis With Respect To Fire And Explosion Investigation. This Paper Will Review The Fundamentals Of Fault Tree Analysis, List Recent Peer Reviewed Papers About The Forensic Engineering Use Of Fault Tree Analysis, Present A Relevant Forensic Engineering Case Study, And Conclude With The Results Of A Recent University Study On The Subject.

SAŽETAK: Prirodni plin danas se smatra najvećim izvorom energije potrebne stambenim područjima i industriji. Pogled na tehnologije kojima se Iran koristi otkriva da su plinovodi najbolji i najsigurniji način za distribuciju prirodnog plina u zemlji. Ovaj izvor energije, koji se ponekad naziva čistim gorivom, ima stratešku ulogu u opskrbi potrebne energije. S druge strane, opskrba gorivom mora biti stalna, ali i sigurna. Stoga se zaključuje da su potrebne odgovarajuće mjere za upravljanje rizicima od curenja, požara i eksplozija na ovakvim postrojenjima. Za postizanje toga cilja najpotrebnije je ustanoviti uzroke nesreća i ispitati pouzdanost. Nadalje, neizbježno se mora procijeniti vjerojatnost događanja nesreće na cjevovodima. Jedan od ključnih koraka u procesu vrednovanja rizika jest procjena vjerojatnosti mogućih nesreća. Članak se koristi FTA (fault tree analysis) metodologijom za proučavanje načina procjene vjerojatnosti nesreća na cjevovodima za prirodni plin. Nadalje, ponuđena je i nova metoda temeljena na pridruživanju težina stablu kvarova, a ‘what-if’ (što-ako) scenarij služi za utvrđivanje opasnosti pri transportu prirodnog plina od njegova glavnog izvora. Na osnovi rezultata studije predlaže se da se vjerojatnost događanja nesreća na cjevovodima za prirodni plin kontrolira tehničkim i sustavnim pristupom kojim se utvrđuju i kontroliraju uzroci tih nesreća.
