Trend analysis of domestic and international regulations for electric propulsion system

ABSTRACT While regulations are being strengthened to prevent air pollution from ships in Korea and other countries, the Korean government has passed the Eco-Friendly Ship Act, which is effective from 1 January 2020. Therefore, for coastal ships constructed in Korea, the emission of air pollutants should be reduced by alternative fuel and improving their propulsion system. Accordingly, the Ministry of Oceans and Fisheries in Korea has announced a plan to promote the conversion of all 140 government ships into eco-friendly ships using liquefied natural gas or electric propulsion systems by 2030. To apply these propulsion systems, rules, and regulations of the Korea government must first be reorganized. In this study, the type and development trend of electric propulsion systems are reviewed, and trends in regulations for installing electric propulsion systems on ships in various countries, including the United States and Europe, and institutions, including the IEC, IEEE, and International Maritime Organization, are analyzed. Finally, the standardization of the regulation system is discussed to facilitate the introduction of eco-friendly ships to Korea, and relevant implications will be presented.
