Abstract

Transportasi laut masih bergantung pada penggunaan bahan bakar fosil berbasis minyak bumi. Hal ini menjadikan sektor pelayaran menyumbang emisi gas rumah kaca CO2 sebesar 2,89% di tahun 2018. International Maritime Organization (IMO) telah berupaya mengurangi emisi menuju net-zero emission tahun 2050. Salah satu strategi yang dapat dilakukan yaitu transisi ke bahan bakar alternatif yang lebih ramah lingkungan, yaitu penggunaan bahan bakar Liquefied Natural Gas (LNG). Dalam penelitian ini bertujuan untuk menganalisis kelayakan teknis dan ekonomis penggantian mesin bantu diesel generator dengan mesin dual-fuel berbahan bakar LNG pada kapal tanker 30.000 DWT. Pada aspek teknis di dapatkan spesifikasi mesin yaitu HiMSEN 6H27DF dual-fuel dengan kebutuhan daya sebesar 1300 kW dan putaran RPM sebesar 720. Selanjutnya untuk konsumsi bahan bakar LNG yang dibutuhkan yaitu sebesar 17.701 liter sehingga diperoleh kebutuhan ISO Tank dengan volume 20.000 liter atau setara dengan 20 feet. Didapatkan hasil analisis kelayakan berdasarkan parameter NPV sebesar IDR 3.847.385.319, IRR sebesar 16,11%, Payback Periode proyek sebesar 6,75 tahun dan Benefit Cost Ratio (BCR) sebesar 1,21. Dari analisis kelayakan yang didapatkan, seluruh indikator menunjukkan hasil yang positif dan memenuhi kriteria kelayakan investasi, sehingga penggantian mesin bantu diesel generator menjadi mesin dual-fuel berbahan bakar LNG pada kapal tanker 30.000 DWT cukup layak untuk diterapkan, baik dari segi teknis maupun ekonomis. =====================================================================================================================================
Maritime transportation still relies on petroleum-based fossil fuels. As a result, the shipping sector accounted for 2.89% of CO2 greenhouse gas emissions in 2018. The International Maritime Organization (IMO) has been working to reduce emissions with the goal of achieving net-zero emissions by 2050. One strategy that can be implemented is the transition to more environmentally friendly alternative fuels, specifically Liquefied Natural Gas (LNG). This study aims to analyze the technical and economic feasibility of replacing diesel generator auxiliary engines with LNG-fueled dual-fuel engines on a 30,000 DWT tanker. From a technical perspective, the engine specifications are a HiMSEN 6H27DF dual-fuel engine with a power requirement of 1,300 kW and an operating speed of 720 RPM. Furthermore, the required LNG fuel consumption is 17,701 liters, resulting in a need for an ISO tank with a volume of 20,000 liters, equivalent to a 20 ft container. The feasibility analysis results, based on the Net Present Value (NPV) parameter, are IDR 3,847,385,319, an Internal Rate of Return (IRR) of 16.11%, a project payback period of 6.75 years, and a Benefit-Cost Ratio (BCR) of 1.21. Based on the feasibility analysis, all indicators show positive results and meet the investment feasibility criteria; therefore, replacing the diesel generator with an LNG-fueled dual-fuel engine on a 30,000 DWT tanker is feasible, both from a technical and economic perspective.
