Statistical analysis of the energy efficiency performance (EEDI) of new ships built in 2013-2017
Year: 2017 Language: english Author: Transport & Environment Genre: Research papers Format: PDF Quality: eBook Pages count: 10 Description: Statistical analysis of the IMO’s EEDI database concluded that a substantial share of the new build fleet already complies and over-complies with current and future (2025) design efficiency requirements. Notably, 71% of containerships, 69% of general cargo ships, 26% of tankers and 13% of gas carriers already comply with the 2025 EEDI requirement (i.e. -30% reduction compared to reference line). For bulk carriers, however, this share is less than 1%. Additionally, the study reveals that the top 10% of the best ships in each class category are doing far better than the average new ships in the fleet. Notably, the average performance of the best (top 10%) ships is around 58% for containerships, 57% for general cargo ships, 42% for gas carriers, 35% for oil tankers and 27% for bulk carriers relative to the reference line (Fig. 1). For this reason, the study recommends that the revision of existing EEDI targets and the setting of future design standards should be based on the performance of the 10% best ships in each segment.
