Abstract

Liquefied natural gas (LNG) is utilized as a dual fuel source in maritime engines, where LNG serves as the primary fuel and diesel acts as the secondary fuel. In pursuit of heightened energy efficiency and diminished environmental effects within the shipping sector, LNG has surfaced as an eco-friendly alternative compared to traditional diesel. This study seeks to evaluate engine performance measured by specific fuel consumption, engine efficiency utilizing LNG and diesel, and the financial savings in ship operational expenses. This investigation was conducted on the KM ship Nggapulu. The research methodology involved a literature review that entailed recording technical specifications and operational data from the vessel as primary information along with supplementary references from books and journal publications as secondary sources. The collected vessel data includes power output, RPM, cylinder dimensions, piston stroke, and additional parameters necessary for assessing the performance of LNG and diesel engines and calculating operational cost reductions. Findings from the research reveal that the specific fuel consumption for LNG is 0.1403 kg/kWh, whereas for diesel it stands at 0.1847 kg/kWh. The efficiency of the LNG engine is recorded at 0.4646%, in contrast to diesel’s 33.85%. Savings in operational costs amount to 33%. The adoption of LNG as a dual fuel results in enhanced engine efficiency and reduced specific fuel consumption, ultimately leading to lower operational expenses for the vessel.
