A typical modern supertanker can carry approximately two million barrels of oil. In "single-hulled" tankers, the hull is also the wall of the oil tanks, and any breach will result in an oil spill. Newer tankers are "double-hulled", with a space between the hull and the storage tanks, to reduce the risk of a spill in the event that the outer hull is breached. This space is used to carry water ballast when the ship is not carrying an oil cargo.
Garbage Barge Begins Lengthy Trek (March 22, 1987) wrote:Today in Odd History, an unassuming barge called the Mobro 4000 began a 6,000 mile voyage, looking for a port that would take its cargo--nearly 3,200 tons of trash. With its escort, the tugboat Break of Day, the Mobro would sail along the coast of the Eastern and Southern United States, down into the Gulf of Mexico and through the Bahamas, before finally returning to New York, still bearing its load of garbage.
Suezmax vessels – 159,000 tonnes, with a cargo capacity of 1.1 million barrels of oil – are the maximum size of vessel that can transit the Suez Canal, the next size up from Aframax, which carries 700,000 – 800,000 barrels of oil.
The T.T. Jahre Viking is a Norwegian-operated supertanker built in Japan 1976-79, formerly known as the Seawise Giant. Its 1504 feet in length and 226 feet in width makes it the largest ship in the world. T.T. Jahre Viking has a deadweight of 564,763 metric tons and summer displacement of 647,955 metric tons when laden with nearly 4.1 million barrels of crude oil. When fully loaded, she is too big to fit through the English Channel. Sunk by Iraqi missiles in the first Gulf War, she was raised and converted to a floating storage facility.

Sinister? No. Incompetent? Most definately yes. I can just see how that conversation would go.
Mid-level Manager: "Boss, we only had enough crude to fill that super-tanker to 18% of capacity, but I went ahead and sent it on its way even though we don't have a buyer yet."
