Abstract
Penggunaan bahan bakar gas sebagai sumber energi merupakan salah satu upaya yang banyak dilakukan untuk menggantikan bahan bakar minyak. Salah satu cara dengan menggunakan metode dual fuel, dimana bahan bakar yang digunakan perpaduan dari bahan bakar gas dan minyak. Bahan bakar gas yang digunakan pada Tugas Akhir ini adalah Liquified Natural Gas atau disingkat LNG, dimana menurut IMO Tier III bahan bakar tersebut masih memenuhi syarat. Dengan analisis teknis, metode yang dilakukan pertama kali adalah menganalisa konversi mesin dari bahan bakar single fuel menjadi dual fuel. Hasil dari analisa yang didapatkan adalah untuk konsumsi bahan bakar per hari pada sistem bahan bakar dual fuel adalah 2934.36 Kg MDO dan 6194.7 Kg LNG dengan komposisi 30:70. Penambahan komponen lain untuk mendukung sistem bahan bakar dual fuel yaitu pompa kriogenik dan vaporizer, gas valve unit (GVU). Dengan penambahan komponen, diperlukan modifikasi pada general arrangement. Pada instalasi perpipaan, untuk pipa yang berada di cargo area / open deck harus memiliki karakteristik yang dapat tahan terhadap korosi. Untuk itu dipilih bahan pipa yaitu stainless steel grade 304L. Sedangkan pipa untuk diarea engine room, menggunakan double piping system dengan material carbon steel dan sesuai berdasarkan The International Code of Safety for Ships Using Gases or Other Low-Flashpoint Fuels. Berdasarkan hasil analisa pada Tugas Akhir ini, konversi diesel engine menjadi dual fuel pada kapal Ferry Ro-Ro layak dilakukan berdasarkan kebutuhan main engine, general arrangement kapal dan sesuai dengan rules.

The use of gas fuel as an energy source is one of the many efforts taken to replace fuel oil. One of them uses a dual fuel method, where the fuel used is a combination of gas and oil fuel. Gas fuel used in this paper is Liquefied Natural Gas or LNG, where according to IMO Tier III the fuel is requirement. With technical analysis, the first method is to analyze the engine conversion from single fuel to dual fuel. The results of the analysis obtained are for fuel consumption per trip in dual fuel system is 2934.36 kg MDO and 6194.7 kg LNG with a composition of 30:70. Addition of other components to support dual fuel systems such as pumps, vaporizers, gas valve units (GVU). With the addition of components, modification is needed in general arrangement. In pipping installations, pipes that are in the cargo area / open deck must have characteristics that can withstand corrosion. For this reason, we choose 304L grade stainless steel pipe material. While the pipes of engine room areas, use a double wall piping system with carbon steel material and according to the International Code of Safety for Ships Using Gases or Other Low-Flashpoint fuels. Based on the results of the analysis in this paper, the conversion of diesel engines to dual fuel on a Ferry Ro-Ro vessel is feasible based on the need of the main engine, general arrangement of the ship and in accordance with the rules.
