Τhe current thesis is initially aimed at presenting the measures that have been adopted by the IMO for improving the energy efficiency of commercial vessels and particularly cargo ships, namely the presentation of the Energy Efficiency Design Index (EEDI) and the Ship Energy Efficiency Management Plan (SEEMP). However, it is mainly concerned with the analysis of the Energy Efficiency Operational Indicator (EEOI) based upon the operational data of 45 tankers with reference to the navigable part of their trips during the period 01/01/2013-31/12/2013. The results lead to the conclusion that in order to achieve the highest operational energy efficiency, the vessels should be chartered to their maximum available capacity and sail at speeds of reduced fuel consumption. Finally, due to the difficulty of choosing a voyage with ideal characteristics in such a dynamic and volatile shipping market, the use of measures and technologies is recommended in order to reduce the fuel consumption and thus to contribute to the improvement of the values of the Energy Efficiency Operational Indicator (EEOI).
