Review of ship energy efficiency
Despite being named as an "energy efficiency index", the EEDI is primarily a CO 2 emission measurement, which is usually related to the energy efficiency, but it only evaluates a part of the ship''s power system and in only one operating point, meaning that its usefulness as an energy efficiency measure is questionable (Ančić et al., 2018).
