Abstract

Besarnya Fuel Oil Consumption (FOC) di kapal, jumlah demand BBM yang besar dibandingkan dengan ketersediaan, serta kebutuhan modernisasi transportasi laut harus segera diwujudkan dalam pembangunan nasional menjadi latar belakang penelitian ini. Untuk menyelesaikan masalah tersebut dibuat penelitian tentang penggunaan dual fuel (DF) untuk transportasi laut. Dalam penelitian ini dirumuskan rumusan masalah yaitu bagaimanakah modifikasi sistem yang dilakukan untuk fuel system pada konversi single fuel (SF) ke DF (HSD-LNG), berapakah FOC untuk SF dan DF (HSD-LNG) sebelum dan setelah dilakukan konversi, serta bagaimanakah perbandingan kajian ekonomis dari konversi SF ke DF (HSD-LNG). Metode yang digunakan adalah teoritis perhitungan serta studi lapangan. Kapal yang dikonversi adalah kapal ferry lintasan Merak-Bakauheni dengan sample tiga kapal ukuran yang berbeda. Hasil yang didapatkan yaitu modifikasi dilakukan dengan menambahkan gas transfer dari storage menuju ke main engine meliputi LNG Storage, LNG Cryogenic Pump, Heat Exchanger, Gas Valve Unit (GVU), dan Conversion System. Untuk penghematan yang dilakukan dari FOC adalah rata-rata 46,79% dari ketiga kapal ======================================================================================Total Fuel oil that consumed on vessel, demand of fuel oil that not balance with the avaliability on global energy and modernization of sea transportation units that should be realized on Indonesia development program are the main background for this research. The new marine technology to reduce FOC is using Dual Fuel System for the engine operation. Refer to previous research, dual fuel system can reduce the total FOC and more efficient in cost operational. This research discuss regard to how to modified single fuel (SF) to dual fuel (DF) system using HSD and LNG as fuelled vessel, FOC comparation between SF to DF, and economical analysis SF and DF system. For the methodes using theoritical and field study for the valid system. For the vessel that will be discussed are three vessel on Merak-Bakauheni voyage as the sample of the ferry in Indonesia by three class of the difference load. The result, modification conducted by modified engine and install gas transfer from LNG storage to main engine consist of LNG tank, LNG Cryopump, Vaporization Units (Heat Exchanger), Gas Valve Units (GVU) and Conversion Units. Total of the saving cost of FOC is 46,79%
