How much does a oil tanker weigh full?

The weight of a fully loaded oil tanker can vary significantly depending on its size and capacity. Large oil tankers, such as supertankers, can weigh around 300,000 to 500,000 deadweight tons (DWT), which includes the weight of the ship itself, cargo, fuel, and other supplies. This translates to a total weight of approximately 250,000 to 400,000 metric tons when fully loaded with oil. Smaller tankers will weigh less, but the full weight still remains substantial.
