The Marine Environment Protection Committee (MEPC) of the International Maritime Organization (IMO) is conducting a review of the 2020 requirements of the Energy Efficiency Design Index (EEDI). In the current regulation, a ship built after 1 January 2020 needs to have an EEDI that is 20% below the reference line value for that ship. The aim of this project is to analyse which EEDI requirements are readily achievable for bulk carriers, tankers, general cargo ships and containerships.
