The matter of poor power factor for marine electrical systems due to motor loads is often overlooked and can be improved by adding power factor correction capacitors, resulting in energy savings. This study examines two alternative methods for predicting alternator fuel consumption in vessels, and the obtained results are verified by field measurements. Moreover, a return-on-investment period of installing power factor correction on two fishing vessels is analyzed to determine the critical parameters governing economics of power factor correction in marine electrical systems. Test results show the payback period on installing power factor correction will significantly depend on the alternator running hours per year and the price of fuel oils.
