Consideration of Energy Efficiency Operational Index evaluation

Abstract

The Energy Efficiency Operational Indicator (EEOI) is a monitoring tool for managing ship and fleet efficiency performance over time. The EEOI enables operators to measure the fuel efficiency of a ship in operation and to gauge the effect of any changes in operation, e.g. improved voyage planning and more frequent propeller cleaning, or the introduction of technical measures such as waste heat recovery systems or a new propeller. The EEDI index implies a minimum acceptable level in terms of ship energy efficiency, quantified by CO 2 emissions and relative to freight and transport distance. Supported values will be reduced depending on the implementation phases. It expects the implementation of this index to drive the deployment of innovative shipboard technologies to influence their energy efficiency. The values of the reduction factors have a decreasing trend during the implementation periods, reaching a minimum of 30% reduction of the pollutant emissions in the years 2025 compared to the levels before the implementation of this index. EEDI has been conceived as the largest and most powerful segments of the maritime industry.
