Abstract
Measuring fuel consumption on board ship in real time is important because it helps shipping companies to monitor the fuel consumption of each ship. From the collected data, the shipping company can evaluate the energy efficiency of the ship in the operation. The research team has designed and built a monitoring system to monitor fuel consumption in the real time. This system is used IoT technology to transmit data continuously from the ship to the control center. A marine diesel engine was tested at various loads from 20-80%. Experiment results show that the amount of fuel was accurately measured and continuously transmitted to the monitoring center in real time. Based on continuously collected data, it will help shipping companies to evaluate the energy efficiency and detect any abnormal condition of the engine from which to take remedial measures. and timely repair to prevent possible troubles.
