Abstract

The documents concerning the calculation of conversion coefficients for marine fuels are reviewed to see the rationality of the conversion coefficients given by IMO. The method of calculating the coefficients is analyzed. Inconsistency in given atomic weight approximations for carbon, hydrogen and oxygen is found. Besides, the fundamental data source is not up to date. These problems are degrading the accuracy of carbon emission calculations. The corrections for the conversion coefficients are proposed. The conversion coefficients for ethane and bio-gasoline/biodiesel are calculated. A proposal on timely revising the conversion coefficients is prepared. Prudent treatment is suggested in using the conversion coefficients given by IMO to evaluating domestic emissions.
