The Merits of Using MGO (distillate fuel)
Similar to MDO and distillate fuel, marine gas oil (MGO) is a high-quality and environmentally-friendly fuel compared to HSFO（heavy fuel oil）, which has been used in marine diesel engines up to now. Although the price is a bit high, it has good flammability, reducing engine trouble, and there are no issues with availability. Also, using a single MGO fuel makes the system simple, which leads to keeping the capital investment, operation, and ship maintenance costs low.
Fuel tanks, pumps, purifiers, filters, and heat race piping are among the on-board devices that can be significantly reduced and made to be more compact.
This leads to low fuel consumption, which can offset the high price of the fuel.
Feature of MGO(distillate fuel) and the other fuels
|MGO, MDO||VLSFO (Compliant fuel)||HSFO (Heavy fuel oil)||LNG|
|Fuel price||Expensive||Relatively Expensive
Close to MGO?
|Cheap||Close to HFO|
|Fuel availability||Good||Good||Good at present
|Fuel property||Good||No specification
Fuel stability / Fuel compatibility
Long ignition delay / Poor combustion
Higher pour point
|Same as the present||Good|
|System||Very simple due to mono fuel / no heating system||same as the present||SOx scrubber||DF engine + LNG tank and supply system|
|Additional initial cost||Small||Unnecessary||Very large||Huge|
|Operation||Easy||same as the present||Complicated||Very complicated system
Only by skillful engineer
|Other aspect||Higher engine reliability and less maintenance||Concerned about the engine and fuel system trouble||Limited production and dock capacity for installing SOx scrubber
Limited scrubbing water dischange area
|Application||Very potintial solution with MGO mono-fuel engine UEC-LSJ||Majority||Limited||Very limited|
