oil tanks are cargo hold in oil tanker.
OBO ships ( oil bulk ore) having oil tanks which is similar to cargo hold in bulk carrier
Normally a Tanker carries some liquid, mostly Oil, therefore the term "Oil Tanker".

The capacity of a product oil tanker can vary significantly depending on its size and design, but they typically hold between 25,000 to 80,000 deadweight tons (DWT) of cargo. This translates to approximately 180,000 to 600,000 barrels of oil. Larger tankers, known as medium range (MR) or long range (LR) tankers, can hold even more, with some exceeding 100,000 DWT.
The oil cargo goes into cargo tanks, the fuel oil or bunker goes into the bunker tanks. The lubrication oil (lube oil) goes into the lube oil tanks.

The amount of oil a tanker ship can hold varies significantly depending on its size and type. For example, a typical Aframax tanker can carry around 80,000 to 120,000 deadweight tons of oil, while a supertanker like a Very Large Crude Carrier (VLCC) can hold approximately 200,000 to 320,000 deadweight tons. This translates to roughly 1.4 million to 2 million barrels of oil for a VLCC, depending on the specific design and cargo conditions.
2,000,000 barrels.
A ship with a cargo rides lower in the water than when it has no cargo. As the cargo is unloaded, the ship rises in the water, revealing parts of the hull which had been below the water level. What the observer was looking at was a ship which was in the process of delivering its oil to the terminal.
2 million barrels
The capacity of a tanker ship can vary significantly depending on its size and design. A typical crude oil tanker can hold anywhere from 500,000 to over 2 million barrels of oil. For example, very large crude carriers (VLCCs) usually have capacities around 1.9 million barrels. Smaller tanker ships, like Aframax or Suezmax, generally hold between 500,000 and 1 million barrels.

A tank in a tanker into which slops are pumped. These represent a residue of the ship's cargo of oil together with the water used to clean the cargo tanks. They are left to separate out in the slop tank.
