After an extensive discussion in the Marine Environment Protection Committee (MEPC), Resolution MEPC.203(62) was adopted, introducing the EEDI. New regulations intend to improve energy efficiency for ships and reduce the emissions of any substances that originate from fuel oil and its combustion process. Even though the new regulations should encourage the use of innovative energy efficient technologies, the EEDI formula in its current form is not applicable to some kinds of innovative ship power systems, such as integrated power systems (IPS). IPS as well as other technologies should also be properly evaluated so that the optimal configuration can be identified and implemented. This paper analyses how the attained EEDI is changed with the introduction of new power sources in the ship power system. This change is compared to the improvement in the overall energy efficiency and the reduction in the CO2 emission. The analysis of a ro-ro passenger ship showed that the current design does not meet the requirements of the required EEDI. The implementation of two innovative technologies, wind and photovoltaic power generation system, is proved to be feasible. However, these technologies have very small impact on the attained EEDI, because in its current form the EEDI formula does not capture all their benefits. To better evaluate ecological aspect of these technologies, a life cycle analysis (LCA) could be performed.
