What is RMG fuel oil?
Residual Marine Fuel Oil (RMG) , FO380cst, FO180cst , Intermediate Fuel Oil (IFO), Heavy Fuel Oil (HFO) Fuel oil is mainly used in the diesel engines of marine ships. It is obtained during the process of crude oil refining. It consists of all the fuels that have non-boiling fractions.
What is RMG and RMK?
The most common residual fuels in the shipping industry are RMG and RMK. The differences between the two are mainly the density and viscosity, with RMG generally being delivered at 380 centistokes or less, and RMK at 700 centistokes or less.
What RMG 380?
IFO 380 and IFO 180 (RMG) are the fuels most commonly used in shipping. The ISO 8217 standard also defines a marine fuel’s quality parameters, e.g. ignitibility (Calculated Carbon Aromaticity Index/CCAI), maximal acid and metal content, and sulfur content limits.
What is DMX fuel?
DMX is a special light distillate intended mainly for use in emergency engines. DMA (also called marine gas oil, MGO) is a general purpose marine distillate that must be free from traces of residual fuel. DMX and DMA fuels are primarily used in Category 1 marine engines (< 5 liters per cylinder).
Is marine fuel ethanol free?
Ethanol free fuel is the best option for marine engines, but E10 can still be used if necessary. The most likely time for fuel problems to occur is when you first begin using ethanol-blended fuel, because of phase separation.
What is Bunker C?
Bunker C is the residual oil left over after the lighter, more volatile products (gasoline, #2 diesel, natural gas) are distilled out of the crude oil. These systems can handle the by-products and so heavy fuel oil becomes the best fuel for their needs because it is also markedly cheaper than gasoline or diesel fuel.
What is RMK in fuel?
RMK 500 & 700 fuels are made from the same basic components as lower viscosity fuels, with cutters (such as cycle oils, gas oil, etc) being used in varying proportions to achieve the required viscosity and density of the fuel grade.
What does IFO 380 stands for?
intermediate fuel oils
The resulting blends are also referred to as intermediate fuel oils (IFO) or marine diesel oil. They are classified and named according to their viscosity. The most commonly used types are IFO 180 and IFO 380, with viscosities of 180 mm²/s and 380 mm²/s, respectively. The latter are collectively called heavy fuel oils.
