4 Establishing an Energy Efficiency Operational Indicator (EEOI)

 The EEOI should be a representative value of the energy efficiency of the ship operation over a consistent period which represents the overall trading pattern of the vessel. Guidance on a basic calculation procedure for a generic EEOI is provided in the Appendix.

In order to establish the EEOI, the following main steps will generally be needed:

  • .1 define the period for which the EEOI is calculatedfootnote;

  • .2 define data sources for data collection;

  • .3 collect data;

  • .4 convert data to appropriate format; and

  • .5 calculate EEOI.
