The Energy Efficiency Operational Index (EEOI) is the novel important challenge that the shipping companies have to face associated with the Ship Energy Efficiency Management Plan (SEEMP) in accordance with the International Maritime Organization (IMO) MARPOL (International Convention for the Prevention of Pollution from Ships) Annex VI regulations. The EEOI obtains a quantitative indicator of energy efficiency of a ship in operation, hence it might be considered as the primary monitoring tool for ship efficiency performance and to optimize the performance of the ship. In this study, changing of the ship EEOI is investigated in case of fully and partial laden of the sample ship named M/V Ince Anadolu. It is revealed that operating in fully laden of ships have an importance as much as efficient operation of energy consuming systems to reduce CO2 emissions from ships. Moreover, it is obvious that the fleet management policy of companies has been monitoring as much as one ship. In this context, the novel term “Fleet Energy Efficiency Management Index” (FEEMI) is defined to measure the energy efficiency management ability of the companies.
