On energy efficiency of inland waterway self-propelled cargo vessels
Abstract
The Energy Efficiency Design Index (EEDI) was introduced by IMO - Marine Environment Protection Committee in order to stimulate innovation and technical development of all elements that influence energy efficiency of a ship from its design phase. According to definition, it represents weight of ship’s CO2 emissions per transport work. Baseline equations for EEDI were developed for several most common types of seagoing ships. This paper presents one of the first attempts to evaluate EEDI of inland-waterway, dry-cargo, self-propelled vessels. Within research that is explained in the paper, full-scale measurements were performed with the purpose to enrich the database according to which new mathematical model for power evaluation was developed. Large differences between the model- and full-scale measurements were also analysed. Finally, application of relatively large power margins for inland-waterway ships was suggested. EEDI baseline can be used as a benchmark of future ship designs.
