The IFO (Intermediate Fuel Oil) is marine fuel belonging to the residual fuel group used by tankers in the international markets, also called bunker.

It is designed to be used it as fuel in tankers and generators plants of electric energy. The use of one of these fuels is conditioned by ship manufacturers and ship -owners.
