The EEDIwill as such stimulate continuous technical development offuel efficient ships. At the same time it enables acomparison of the energy efficiency of individual ships tosimilar ships of the same size and ship type. The EEDI willbe included in a new International Energy EfficiencyCertificate (IEEC) that will be introduced for all vessels.The EEDI is based on a formula for calculation of shipspecific emissions of CO2. The result for each ship, whichis to be based on design documentation and engineperformance, is expressed in grams of CO2 per capacitymile.Once the EEDI is put into force the attained EEDI fora specific ship must be less or equal to the required EEDI,expressed by reference lines developed by IMO for eachship type. The EEDI reference lines will become morestringent with time as reduction factors are planned to beapplied in different phases starting in 2013.Det Norske Veritas AS16 | Tanker UPDATE NO. 2 2011
