The selection of fuel is an important aspect for following environmental laws as well as ensuring effective operation in the maritime transportation industry. Marine Gas Oil (MGO) is one of the fuels that is often utilized in the shipping sector. However, various individuals ask what exactly marine gas oil is and why it is so significant.
This informative piece will give you a complete overview of marine gas oil, regardless of whether you work in the field or are just interested in learning more about marine fuels. Let's understand deeply what marine gas oil is.

What is Marine Gas Oil?
Marine gas oil, often known as low-sulfur fuel oil (LSFO), is a bunker fuel used in maritime boats. Crude oil is distilled to produce this fuel distillate.
The distillation process separates crude oil components based on their boiling points. At varied temperatures, these compounds evaporate before condensing back into liquid. This process creates a variety of fuels, including gasoline, diesel, kerosene, marine fuel, and gas oil. Marine gas oil, or MGO, is denser than diesel and does not require heating during storage, unlike HFO (Heavy Fuel Oil).
You can purchase gas oil if you own a boat and use it for recreational purposes, but you must pay the full tax rate. This has been accompanied by bunker fuel.
What is Bunker Fuel?
The term "bunker fuel" is widely used in the maritime and offshore industries. Bunker fuel is derived from the term "fuel bunker," which refers to a storage compartment inside a boat or other vessel for fuel. It was originally used on steam-powered ships. Bunker fuel refers to any fuel, other than marine gas oil, that is stored aboard a ship. Other bunker fuels include HFO, MDO, MFO, and MGO.
The fuel you intend to use will affect the type of vessel you have; for example, marine boats' engines run on bunker fuel. It may not be your average DERV, though. Larger ships often get their fuel from marine gas oil.
Because bunker fuel isn't limited to any one form of fuel, it can be used with a range of fuel types:
MGO, or Marine Gas Oil
MDO, or Marine Diesel Oil
Fuel Oil Intermediates (IFO)
MFO, or Marine Fuel Oil
HFO, or heavy fuel oil.
Until recently, HFO powered the majority of large commercial ships. Today, the MGO is widely used in a variety of applications based on its specifications.
Marine Gas Oil Specifications and Uses
Maritime gas oil is used on a variety of maritime vessels, including tankers, cargo ships, passenger ships, smaller boats, and yachts. It generates heat and electricity, in addition to powering the engines. Marine gas oil is also used in various industries, such as agriculture for tractors and farm equipment, and as a backup fuel for diesel generators. Some notable applications of MGO are listed below.
Uses for Marine Gas Oil
-
Typically used as a fuel for maritime vessels such as cargo ships, tankers, and passenger ships.
Also used on smaller vessels and yachts.
Fuels ship engines.
Used to generate heat and electricity on ships.
Other Uses of Marine Gas Oil
-
Power generation: Used as a backup fuel for diesel generators.

Marine Gas Oil Specifications
For maritime boats to use marine gas oil, it needs to fulfill specified requirements. The International Maritime Organization (IMO) and the International Organization for Standardization (ISO) have established these requirements. The IMO Annex VI and ISO 8217 are the most widely used specifications for marine gas oil.
Sulfur Cap Set by the International Maritime Organization (IMO)
This law, which went into force in 2020, is primarily intended to lessen air pollution and shield ecosystems from the damaging impacts of sulfur emissions, such as acid rain. Shipping companies must utilize scrubbers or exhaust gas cleaning systems, investigate alternate biofuels, or convert to low-sulfur fuels in order to comply.
ISO 8217
The requirements for marine fuels used in marine diesel engines and boilers are outlined in this international standard. It addresses a number of topics related to marine fuels, including their chemical makeup, physical qualities, and performance traits.
By guaranteeing the quality and compatibility of marine fuels, this standard seeks to improve the safety and efficiency of ship operations.
IMO Annex VI
Air pollution from marine vessels is regulated by MARPOL Annex VI of the International Maritime Organization. This rule restricts the release of sulfur and nitrogen oxides from ship exhausts, which are harmful to the environment.
The term "ECA" refers to the designated emission control areas that are established in Annex VI. The utilization of alternative fuels and energy-efficient technology is encouraged in these regions with more stringent emission regulations. This is to lessen the pollution that shopping activities produce.
Benefits And Drawbacks: Marine Gas Oil
Although MGO utilized in multiple applications, it comes up with benefits as well as drawbacks. Below are mentioned some potential benefits and drawbacks of MGO.
| Aspect | Benefits | Drawbacks |
|---|---|---|
| Sulfur Content | Low sulfur content meets IMO regulations, reducing air pollution. | Higher cost compared to heavy fuel oil (HFO), impacting operating expenses. |
| Engine Maintenance | Cleaner combustion reduces maintenance needs and engine residue buildup. | Not completely free from greenhouse gases, contributing to climate change. |
| Performance | Superior cold-weather operation and fuel stability remain fluid in low temperatures. | Limited energy density may require more frequent refueling, affecting operational range. |
| Contamination Risk | Less prone to microbial contamination, enhancing safety and efficiency. | Less efficient in high-load scenarios compared to heavier fuels. |
| Availability | Widely available in ports worldwide, facilitating easier refueling. | Transition requires engine modifications, potentially leading to high upfront costs. |
Difference Between Marine Gas Oil vs Heavy Fuel Oil
| Fuel Type | Marine Gas Oil (MGO) | Heavy Fuel Oil (HFO) |
|---|---|---|
| Composition | Refined distillate, similar to diesel, lower viscosity. | Residual fuel, higher viscosity and density. |
| Sulfur Content | Lower sulfur content, compliant with stricter regulations. | Higher sulfur content, higher emissions without mitigation. |
| Use | Smaller vessels, auxiliary engines, backup fuel. | Large vessels, main engines for propulsion. |
| Storage and Handling | Easier to store and handle due to lower viscosity. | Requires heating for pumping, more complex handling. |
HFO is a heavier, less costly fuel that is mostly used in large marine engines but is subject to harsher environmental regulations due to its higher emissions. MGO, on the other hand, is lighter, cleaner, and suitable for compliance with stricter emissions standards.
