RMD80

RMD 80 - unchanged from ISO 8217:2010 - most resembles 60 / 80 cst. Produced with a low pour point for smaller vessels without tank heating. Higher pour point though than RMB 30.

*Statutory - in an ECA this must be max 1%S and 3.5%S for all other areas. However, some areas may not have 3.5% available. The Global Cap brought into force on 1st January 2012 has no grace period under Marpol Annex VI. Also, there is no policy for residual fuel aboard with sulpur content more than 3.5%. If fuel is higher than 3.5%in sulphur content than this is not compliant with Marpol Annex VI.

 *Formula for CCAI:

 CCAI=D-140.7 \log (\log (V+0.85))-80.6-210 \ln \left (\frac{t+273}{323} \right )

 which is equivalent to:

CCAI=D-140.7 \log (\log (V+0.85))-80.6-483.5 \log \left (\frac{t+273}{323} \right )

Where:

D= density at 15°C (kg/m3)
V= viscosity (cST)
t = viscosity temperature (°C)
