Diesel Fuel 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. Marine Gas Oil (MGO), other designations is Diesel oil, DMA, DFA, Diesel gas oil and Gas oil. Diesel oil is a crude oil medium distillate and therefore must not contain any residual materials. DFA is a synthetic fuel made by adding FAME additive of 0.5% -100% to DMA. 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. For specifications of Marine Gas Oil (MGO), please refer to MGO (DMA, DFA).
2. Marine Diesel Oil (MDO), also known as Marine diesel fuel, DMB, and DFB. 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. DFB is a synthetic fuel produced by adding less than 7% FAME additive to DMB. 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.
Remarks:
1) The fuel must be suitable for the intended application. It must not contain any substance in a concentration that causes additional air pollution, is harmful for personnel, jeopardises ship safety and/or has an adverse effect on machine performance. The fuel must be free from non-ferrous metals according to DIN EN 16476. The fuel must not contain any waste.oil.
2) Always in relation to the currently applicable edition.
3) Only possible with clear samples. If the sample is not clear or contains visible contamination, the check must be completed mandatorily for the entire sediment.
4) Specific requirements of the injection system must be taken into account.
5) Additional requirements (e.g. SOLAS) must be observed. Applicable laws must be adhered to.
6) Local laws and regulations must be observed independently of the maximum possible sulphur content.
7) The FAME must either be in accordance with EN 14214 or with ASTM D6751 as well as with increased oxidation stability of at least 8 hours (EN 15751).
8) If there is more than 2% (V/V) FAME, an analysis as per EN15751 must additionally be carried out.
