Energy Transport(Tankers)

Tankers transport crude oil, which is the world’s primary energy source, refined petroleum products like gasoline,
and other liquid cargoes such as chemical products.
Tankers, of course, are built to transport oil, but can also serve as temporary offshore oil storage terminals,
because the tanker is composed of multiple tanks.

in Operations Tailored
to Cargo Characteristics

Speaking of tankers, let’s start with the ones that carry oil. Among the larger ones are those that transport crude oil, an energy resource that underpins the global economy and our everyday lives. “Product tankers” also play an essential role, carrying petroleum products such as gasoline, naphtha, kerosene, and diesel oil, and “chemical tankers” transport liquid chemical products including methanol, benzene, toluene, and alcohol.

Liquefied petroleum gas (LPG) tankers carry products such as propane and butane.

Tankers Tailored
to Cargo Characteristics

Crude oil has different properties, depending on where it is produced. For this reason, the cargo tanks on these vessels are normally separated into two or three blocks lengthwise and another several blocks crosswise. In most cases, the cargo is discharged by connecting the pipes of the vessel to the pipes of the terminal (sea berth) located in deep water far offshore.

World’s 1st ‘Methanol tanker’
Equipped with Methanol-fueled Main Engine

Methanol tankers are a type of chemical tanker designed to transport methanol, a type of alcohol used as a raw material for formalin, fuel for alcohol lamps, and so on. In 2016, MOL introduced a methanol dual-fuel vessel, which can run on methanol or conventional fuel oil. As of 2023, the company operates five of the 25 methanol dual-fuel vessels in service worldwide.

Methanol, when used as marine fuel, reduces carbon dioxide (CO2) emissions by up to 15% and nitrogen oxide (NOx) emissions by up to 80%, compared to conventional fuel oil-powered engines. It can also significantly reduce emissions of sulfur oxides (SOx) and particulate matter (PM), since it does not contain sulfur. In addition, if methanol derived from non-fossil raw materials is used, GHG emissions can be further reduced.

In February 2023, MOL became the first company in the world to successfully reduce total GHG emissions during an 18-day transatlantic voyage to net zero* on a life cycle basis, from fuel production to consumption, by using bio-methanol fuel.

* Taking into account the fuel production process, it refers to the total amount of greenhouse gas (GHG) emissions as virtually zero on a life-cycle basis.
