Various sizes of oil tankers are utilised by the maritime sector for oil transportation ranging from modest coastal tankers to VLCC and ULCC tankers.
The increasing worldwide oil consumption since the late 1990s has led to the construction of the ULCC and VLCC tankers to meet the growing demands of the global consumer market.
These tankers have made the international transportation of oil quicker and environmentally safer since they produce fewer hydrocarbon emissions due to their latest designs and specialised features.
They have also done away with most issues faced by the crude oil sector earlier. Thus, they are known for their efficiency and size as the world’s biggest crude oil tanker can accommodate oil enough for one-day consumption of Britain and France combined.
The biggest oil tankers belong to the ULCC or Ultra large crude carrier category followed by the VLCC or very large crude carrier category.
The ULCC has a capacity of more than 320,000 DWT, deadweight surpassing 500,000 DWT, and is more than 400 m long with a draft exceeding 30 m.
The VLCC can accommodate up to 320,000 DWT and some tankers of this size can pass through the Suez Canal. They are more than 300 m long, with a draft of more than 25 m approximately.
More about the biggest oil tankers
These tankers can accommodate more than 3 million barrels of oil and around 2,000,000,000 metric tons of oil is transported annually by waterways in these huge tankers.
Using waterways is economically viable compared to transporting oil via pipelines which would be a much more costly and time-consuming proposition. Also, transporting oil by the biggest tankers adds just 2 to 4 cents to the cost of a gallon, hence making it quite profitable too.
Due to their mass, these tankers have large inertia which makes them cumbersome to steer. A loaded supertanker would require about 5 to 8 kilometres and roughly 15 to 20 minutes to come to a complete halt. They have a turning diameter of nearly 2 kilometres. Oil tankers have an operational life expectancy of 25 to 30 years.
Let us explore the 10 biggest oil tankers in the world.
Euronav Oceania
Euronav Oceania is the biggest oil tanker ship that is currently operational. It is a ULCC, launched in 2003 and built by the South Korean shipbuilding company Daewoo Shipbuilding and Marine Engineering for the shipping corporation Hellespont. The cost of its construction was 90 million dollars.
It was known by numerous names such as Hellespont_Fairfax in 2004, TI Oceania in 2015, Seaways L and Seaways Laura Lynn in 2017 and 2018. However, after its acquisition by the international shipping company Euronav, it was renamed Euronav Oceania. It is registered at Antwerp port and is owned by Euronav Shipping NV and managed by Euronav Ship Management.
It is wider than the New gates of the Panama Canal however its draft restricts it from passing through the Suez Canal unless it is on a ballast journey. It is powered by one Sulzer 9RTA84T-D and has a 50,220 brake horsepower, 37,450 kW At 76 RPM.

This biggest crude oil tanker is presently sailing under the flagship of Belgium. Euronov Oceania has a double hull and is 380 m long, 68 m wide with a draught of around 24 m. Its IMO number is 9246633 and its call signal is ONJP. The carrier’s gross tonnage is more than 234000 tonnes with a summer deadweight of 441585 tonnes. It sails at an average speed of 16.8 knots when it is fully loaded and 17.5 knots when in Ballast. It can carry more than 3 million barrels of oil.
One of its special features is that, unlike other tankers, its bridge wings do not extend to its sides. For keeping the temperature of its steel decks under control, to keep the cargo cool and lower the hydrocarbon emissions, the coating on ballast tanks is preserved by using a double-scrubbing system. Dry inert gases are released into ballast tanks to detect leakages and prevent accidents.
Another sister ship of Oceania is TI Europe built in 2002 and is currently sailing under Belgium’s flagship. Its capacity is 441561 tonnes DWT and its draught is around 12.5 m. Its IMO is 9235268 and it was known as Hellespont Tara earlier. It is owned by Euronav, Antwerp and has the same dimensions and carrying capacity as Euronav Oceania.
Eagle Trader 340m MOL Ship
Eagle Trader is a VLCC operated by MOL Tankship Management Asia, with a capacity of more than 200,000 DWT. MOL ships and carriers have a double engine that can function on methanol as well as conventional ship fuel. It was built in 2018 by Mitsui Engineering and Shipbuilding, a Japanese Company.
