Analysis of Flettner Rotor to Reduce Carbon Emissions in Container and Bulk Carriers

One thousand seventy-six million tonnes, or 2,89% of world carbon emissions, result from maritime transportation annually. One of the solutions to tapering down this trend is to create fossil-free renewable energy. Due to weather conditions, wind energy is the potential energy to achieve significant fuel savings. Flettner rotor is feasible for several container carriers with various deadweight tonnage (DWT), rotor dimensions, and efficiency results. This research conducted in the Indonesian Sea uses a parametric calculation to analyze the application of the Flettner rotor in several types of bulk and container carriers with six rotor specifications to minimize carbon emission and optimize the load. This study shows the optimal efficiency of ships after using the Flettner rotor. Flettner rotor can reduce 330.15 kg of fuel in 251,667 DWT of bulk carrier and 559,22 kg on 94,727 DWT container carrier. This study also proves the decrease of carbon emission to 288.86 kg in the bulk carrier and 488.98 kg of carbon emission from the container carrier after using the Flettner rotor. This result of efficiencies can be modified and raised according to the number of installed rotors.
