    • New ships: Design efficiency since 2009

    This study and accompanying briefing analyse the development of the design efficiency of ships that have entered the fleet from 2009 to 2016. As the Energy Efficiency Design Index (EEDI) of a ship can only be determined in a sea trial, this study uses a simplified version called the Estimated Index Value (EIV). The EIV can be calculated on the basis of publicly available information and the EIVs of ships that entered the fleet between 1999 and 2008 were used to calculate the reference values. The EIV is higher than the EEDI on average, meaning that ships are generally more fuel efficient than the EIV suggests.

    The study finds that based on an analysis of EIVs, the average design efficiency of new ships has improved in recent years. However, the efficiency improvements seem to have stalled in 2016. On average, the design efficiency of new bulk carriers, tankers and gas carriers was worse in 2016 than they were in 2015. Also the share of ships below the reference line and the share of ships meeting or exceeding Phase 1, Phase 2 or Phase 3 required EEDI values has decreased in 2016. The design efficiency of container ships and general cargo carriers was more or less at the same level in 2016 as in 2015.
