Numerical modeling of magneto electric co-generator plant for sustainable marine vessel power system

The number of vessel around the world continued to increase yearly to fill the world trade demand. Consequently, the fuel usage increase due to increasing requirement for propulsion and electricity. Generator is the heart of a vessel that supplies electricity to most ship`s components. This study involves how to reduce the usage of generator in ship’s operations. The Magneto Electric Co-generator Plant (MECP) is the combination of some equipment, electronic, circuit and recycling the shaft rotational energy for additional electrical distribution. MECP proposed to be installed at propeller shaft and main engine flywheel of UMT vessel. The regeneration system can supply electricity to auxiliaries’ component of ship machineries. The total produced energy by MECP is computed by modeling numerically. Cost saved yearly is estimated based on the power produced and fuel cost. In this study, the possibility of the co-generator plant to be used for vessel is determined by considering the efficiency and cost saving. Cost saved is compared with initial installation cost in order to determine the cost beneficial. The MEPC produced 3.74 KW of power that can be used to supply the ship auxiliaries. It saved 1054 liters diesel per hour and RM 2.62 per hour in general operation cost. Major advantage included in this system is its environmental benefit because it reduces the amount of carbon dioxide footage approximated to 4.13 kg of CO2 per hour that could be emitted to atmosphere. The system could help in commitment maritime industry to climate change
