Two-phase energy efficiency optimisation for ships using parallel hybrid electric propulsion system

Developing a green, intelligent, and efficient power system is an important way for the shipping industry to respond increasingly stringent emission regulations, achieve improvements in energy conservation efficiency. In this study, two-phase efficiency optimisation method proposed reducing consumption. The comprises combination of speed management. On demand side, minimum accumulated consumption required by propeller set as objective function model, whereas on supply lowest cost consumed hybrid management model. An inland parallel electric powered bulk carrier selected case study method. results are compared with data under normal working conditions. show that can reduce 2.60% 9.86% westbound eastbound voyages, respectively. Accordingly, provide methodological support hybrid-powered ships aiming intelligent
