Abstract

Liquefied Natural Gas (LNG) merupakan salah satu bahan bakar gas yang dapat menjadi harapan baru menjawab alternative energy di Indonesia, serta untuk mengurangi penggunaan minyak bumi yang semakin menipis. Selain sebagai energi alternatif pengganti solar, LNG dapat menghemat biaya operasional bahan bakar mencapai 20 – 25 %. Pada penyusunan tugas akhir ini akan menganalisa secara teknis mesin dual fuel hasil konversi pada kapal PELNI. Data - data yang diperlukan dalam tugas akhir ini meliputi General Arrangement, Engine Room Layout, Engine Spesification, SFOC, dll. Terdapat beberapa komponen yang harus ditambahkan pada modifikasi dual fuel diesel engine, antara lain : LNG Tank, Heat exchanger, pompa kriogenik dan converter kit. Terdapat pengurangan space container dikarenakan peletakan LNG ISO tank pada cargo hold. Analisa ekonomi dilakukan dengan memvariasikan harga bahan bakar yaitu HSD subsidi dan HSD non Subsidi, serta harga LNG 8 USD, 9 USD, 10 USD, 11 USD DAN 12 USD. Kisaran investasi untuk modifikasi dual fuel sebear 16 – 18 Milyar. Hasil yang didapat dari variasi HSD subsidi dan LNG 8 USD yaitu NPV Rp. 10,428,551,686,58,-, IRR 21.09 % dan payback periode pada tahun ke 4. ================================================================================================================== Liquefied natural gas (LNG) is the one of gas fuel that can be expected for the alternative energy in Indonesia. And also LNG can reduce the using of fuel oil that more decreasing. LNG can get 20 - 25 % fuel operational cost saving. This final project will analyze technically the modification of dual fuel diesel engine on the passenger ships. The supporting data that required are General Arrangement, Engine Room Layout, Engine Specification, SFOC, and etc. the are many components that have to be added for the modification, such as : LNG Tank, Heat exchanger, Cryogenic pump, and converter kit. There is some container losses caused by LNG ISO tank, because the LNG ISO tank located at the cargo hold. N Economic analysis, fuel oil and gas fuel cost will be varied. Rp. 5150 and Rp 8724 per liter for HSD cost. 8 USD, 9 USD, 10 USD, 11 USD and 12 USD/mmbtu for LNG cost. Capital cost to modificate the engine is 16 – 18 Billion. The result based on Rp. 5150 – LNG 8 USD variation are NPV Rp. 10,428,551,686,58,-, IRR 21.09 % and the invstation get the payback periode in 4 years.
