Gas Oil Marine

How is marine gas fuel derived? It’s actually a fascinating process for how this marine fuel comes about. First, crude oil is distilled or boiled off and divided into four categories – refinery gases such as methane, ethane and hydrogen; liquefied petroleum (propane and butane), regular gasoline and distillate fuels.

Marine gas fuel falls into the category of distillate fuels. Each of these distillate fuels are derived at the petroleum’s different boiling points. Marine gas fuel happen the distillate’s highest boiling point. It is considered the heaviest distillate fuel. This fuel is very often mixed with residual oil, which gives it a heavier weight and this is used for large steam boilers and large ocean haulers because these ships are outfitted with massive compression ignition engines that need a heavy fuel.

Marine gas fuel is divided into two basic categories – distillate and residual and the intermediate type we just mentioned. The distillate marine gas fuel is made up of fractions of crude oil that are refined through a boiling process at the refinery. This process is known as distillation. What’s left over is called residuum or residual fuel. It’s commonly known as tar.

In the marine industry, marine gas oil is primarily a distillate fuel type, not a mixture, unless it is being used for the largest ocean ships.

Recreational marine watercraft uses the distillate version of marine gas oil. The commercial or hauling or cargo towing industry uses more of the intermediate marine gas oil. It really depends on the type of engine as to what type of fuel a marine craft takes. For instance, racing watercrafts often have an ignition-combustion engine that require the heavier fuel for performance purposes. Larger yachts, recreational fishing vessels may also use this heavier fuel.

Marine gas oil in the commercial industry depends on three factors – the type of engine, the cost of the fuel and whether it’s available or not. Commercial marine operators work with refiners to come up with marine gas oil that are more cost-effective for their engine types. They are able to lower costs as the amount of refining falls. By leaving the sulfur in the fuel, refiners are able to reduce the cost to below diesel gas.
