Due to global warming, the IMO is implementing regulations on greenhouse gas emissions and fuel efficiency. Regulations on the fuel efficiency of ships include the Energy Efficiency Design Index (EEDI) and the Energy Efficiency Existing Ship Index (EEXI), and many studies are being conducted to meet these regulations. However, these regulations apply mainly to large ships, and regulations for coastal ships are insufficient. Improving the fuel efficiency of small ships is an urgent task for mitigating global warming and improving the coastal environment. In addition, improving fuel efficiency provides more economic benefits for small ship operators. To achieve this, electric propulsion ships and hybrid electric propulsion ships are being developed and implemented. Operating electric propulsion ships requires high initial construction costs and difficulty in expanding charging facilities. Hybrid electric propulsion ships charge surplus power generated by the ship's engine with electricity and use it according to the load, which has the advantage of lower initial construction costs compared to electric propulsion ships and no need for install charging facilities. This paper performed ship resistance CFD and model experiments to determine the output load based on the operating method of hybrid electric propulsion ships. Furthermore, propeller design was conducted, and propeller open water test (POW) was carried out.
