Exploring VLCC and ULCC: The Giants of Oil Transportation

Exploring VLCC and ULCC: The Giants of Oil Transportation

Dive into the world of massive oil tankers, VLCC & ULCC, that dominate our oceans, ensuring the smooth flow of crude oil globally.

In the vast realm of maritime shipping, the Very Large Crude Carrier (VLCC) and Ultra Large Crude Carrier (ULCC) stand out as titans. These oil tankers play a pivotal role, ferrying colossal amounts of crude oil across the globe.

Here's a breakdown:

Weight Matters:

Tankers are measured by Dead Weight Tonnage (DWT). VLCCs can carry up to 250,000 tons, while ULCCs handle between 250,000 to 500,000 tons.

What's in a Name?:

Their classifications - 'very large' and 'ultra large' - highlight their significant cargo-carrying capacities within the 'large' tanker category.

Crude vs. Product Tankers:

While VLCCs and ULCCs are tailored to transport crude oil, product tankers are smaller vessels designed to ship refined products like petroleum.


Due to their immense size and capacity, both VLCCs and ULCCs have earned the moniker 'supertankers'.


It was Shell Oil Company that introduced these classifications, simplifying tanker specifications based on their DWT, ensuring safety and efficiency.

In essence, these mammoth vessels, VLCCs and ULCCs, are the backbone of our global oil transport system, powering our world's energy needs.
