Bunker fuel or bunker oil is technically any type of fuel oil that is used on board ships. Named from tanks on ships and in the ports in which it is stored; these are bunker fuel tanks.
Since the 1980s, the International Organization for Standardization (ISO) has been the generally accepted standard for marine fuels (bunkers). The standard is numbered 8217 with the latest updates in 2005 and 2010. The standard divides the fuel into residual and distillate fuels.

CCAI and CII are two indices that describe the ignition quality of residual fuel oil, and CCAI is especially often calculated for marine fuels.
Despite the fact that this marine fuel is still quoted in the international bunker markets with maximum viscosity (as set out in ISO 8217 - see below) due to the fact that marine engines are designed to use different fuel viscosities.
The unit of viscosity used is centistokes, and the most commonly quoted fuel d6 is listed below in order of cost, the least expensive -
