Calculation of Operational Indicator EEOI for Ships Designed to Other Purpose Than Transport Based on A Research – Training Vessel

Abstract

Applying the Energy Efficiency Operational Indicator as a tool for monitoring the energy efficiency of ships performing other functions or tasks than transport is a problem in the proper assessment of the CO 2 emitted by the vessel during its operation. The analysis of 30 voyages of the research-training vessel showed that the vessel Energy Efficiency Operational Indicator is higher than for transport vessels in the world fleet. The authors suggest that the term „performed transport work” in the indicator calculation method recommended by the International Maritime Organization needs to be modified in terms of operational parameters of this type of ships.
