EEDI Assessment of Recently Built Tankers in Turkey

Eda Turan, Yasin Ust


In recent years, sustainability is the core concern of industries and companies take actions to protect the environment. In this context, there are also several new regulations in the shipping industry. The Energy Efficiency Design Index (EEDI) has been developed and adopted by the International Maritime Organization (IMO) as an amendment to MARPOL Annex VI. According to EEDI, the energy efficiency of ships is defined as the ratio of the mass of CO2 emissions from main, auxiliary engines and additional shaft per unit of transport work for a particular ship design. Other regulations are Energy Efficiency Operational Indicator (EEOI) and Ship Efficiency Management Plan (SEEMP) to be applied to existing vessels. In this study, design data for 84 tankers smaller than 25000 DWT built in Turkish Shipyards between 2009 and 2012 is utilized to calculate and compare their attained EEDI values against the values of the EEDI baseline designated for tankers. The results indicate that most of the delivered vessels do not meet the current EEDI baseline and new vessel designs will be soon necessary for achieving EEDI compliance. This study can also be extended to the application of EEOI with the provision of accurate vessel operational characteristics.
