【 Marine Diesel Oil 】

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


1. Diesel Fuel, Other designations is Diesel oil, DMA, DFA, Gas oil and Marine Gas Oil (MGO). Diesel oil is a crude oil medium distillate and therefore must not contain any residual materials. The ISO 8217-2024 (Class DMA ) standards have been extensively used as the basis when defining these properties. The properties correspond to the test procedures stated.


2. Marine Diesel Oil, also known as Marine diesel oil(MDO), DMB, DFB, and Marine diesel fuel. Its is supplied as heavy distillate (designation ISO-F-DMB) exclusively for marine applications. It is made from crude oil and may contain synthetic components (e.g. BtL, CtL, GtL and HVO). It must be free of organic acids and non-mineral oil products. The properties are essentially defined using the ISO 8217-2024 standard as the basis.


The suitability of fuel depends on the design of the engine and the available cleaning options, as well as compliance with the properties in the following table that refer to the as-delivered condition of the fuel.


All of SOAR’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.
