Since 2013 Energy Efficiency Design Index (EEDI) for new ships will be enforced. Ships meeting the CO2 emission standards will be granted energy certificate required for their exploitation. The paper presents EEDI in the current form, the certification procedure, reduced CO2 emission planned for coming years, as well as potential for further EEDI value reduction.

From 2013 onwards EEDI for newly built ships will become mandatory. Ships meeting the CO2 emission standards will be granted energy certificate for needed for exploitation. The article presents the EEDI in the current form, energy certification procedure as well as reduction of CO2 emission planned for coming years (Part I). The majority of ships built at present, meets the CO2 emission standards for 2013, yet their further decrease in subsequent years will consequently necessitate further actions as well. One of them is ship hull design of smaller resistance values and higher propulsion efficiency. The article (Part II) presents calculation results of the numerical analyses (CFD) performed for an actually built ship, aiming at decreasing propulsion power and therefore the EEDI value as well.
