Abstract

Several technologies are currently being applied in the maritime industry to reduce greenhouse gas (GHG) emissions. An example is the implementation of an electric propulsion system with a battery charged using a renewable energy source. Meanwhile, it is important to analyze the energy demand and the quantity of emissions reduced in a vessel after installing this system. Therefore, this study focused on analyzing the energy demand and emissions produced on fishing boats, specifically the “Sandeq” fishing boats in West Sulawesi. The primary objective was to quantify the carbon dioxide emissions reduced after the conventional engine of the vessel was replaced with an electric propulsion system. Moreover, the energy demand of the boat was estimated by analyzing the daily speed, length of voyage, and engine capacity. The results showed that six batteries were required to provide the power needed for daily operation. Furthermore, the electric propulsion system was able to reduce CO2 emission by 7.94 tons annually per ship, leading to the reduction of fuel consumption and emission taxes to approximately 10 million Rupiah annually. These results were expected to encourage stakeholders to promote the transition from conventional diesel engines to electric-powered engines.

Abstract

Flexible dual-fuel technology is becoming increasingly important in the marine market, where alternative fuels are receiving more attention due to increasing concerns over exhaust pollutant emissions generated by internal combustion engines, fluctuating fuel costs, crude oil depletion, and classification issuing specific rules or guidelines for propulsion systems applied to LNG carriers. Various solutions have been proposed, including the use of alternative fuels. LNG, as a fuel, has been proven and is a viable solution to replace fuel oil. Through this propulsion system technology, it can be more flexible and efficient in accommodating various shipping routes and operations. The study used Rhinoceros, Maxsurf Modeller, and Numeca Fine Marine to integrate the track plan. Calculations of speed and break BHP, and validation of speed-power predictions with HydroComp PropExpert for propeller-engine matching confirmed the selection of dual-fuel engines. Based on the gearbox configuration and LNG load capacity, a dual-fuel ME propulsion system is selected. For large loads, use high pressure, and for small loads, use low pressure with the advantages of better energy efficiency, lower initial cost, slim dimensions, and Tier III NOx standards.
