Marine Diesel Oil is a blend of different middle distillates derived from the crude oil refining process. It is usually composed of light and heavy gas oil, light and heavy cycle oil, as well as vacuum gas oil. The chemical components are alkenes, cyclo alkanes and different carbon hydrides. The boiling range is between 200°C and ~500°C.

The international trading names are DMA (Marine Gas Oil/MGO) and DMB (Marine Diesel Oil/MDO). The main differences between these fuels are their viscosities, densities, as well as their sulphur content.

All of MAN’s liquid fuel engines are capable of burning distillated fuels. Of course, our medium speed dual fuel engines  are capable of burning MFO blended with gas or if gas is not available, in 100% liquid fuel mode.
