This application launched by OW Bunker & Trading A/S is a small practicable tool for look up the ISO 8217 - 2005 & 2010 standards for residual- and destilate marine fuels. Also the coming regulations on sulphur content can be seen in a graphical view
Besides the ISO 8217 & sulphur there is a fuel calculator with following features.

-Specific Energy content.
Acc ISO 8217 Annex E - Calculating the gross and net specific energy content in a residual or destilate fuel.
-CCAI Number
Calculated Carbon Aromatic Index - return the CCAI mumber which is an expression for the ingition quality of a residual fuel based on ISO 8217 annex F
-Temperature Viscosity relations
Return the viscosity of a fuel oil when two viscosity/temperature relations are known for a specific fuel oil
-Volume Correction Factor VCF.
Calculate the volume of a fuel oil corrected to 15 dgr C. or vice versa.
