How many barrels of petroleum does a typical modern ocean-going supertanker hold?
“Supertankers” are generally defined as those greater than 250,000 tonnes deadweight (meaning the maximum weight they can carry when fully loaded). Today’s supertankers, on average, can carry about 2 million barrels or 84 million gallons of crude oil and petroleum product. The largest supertanker in the world is the Norwegian-owned Knock Nevis which is 647,955 tonnes deadweight and can hold 4.1 million barrels of petroleum.
