Seawise Giant, was a ULCC supertanker and the longest ship ever built. It possessed the greatest deadweight tonnage ever recorded. Fully laden, its displacement was 657,019 tonnes (646,642 long tons; 724,239 short tons), the heaviest ship of any kind, and with a laden draft of 24.6 m (81 ft), it was incapable of navigating the English Channel, the Suez Canal or the Panama Canal. Overall, it was generally considered the largest ship ever built. It was sunk during the Iran–Iraq War, but was later salvaged and restored to service. It was last used as a floating storage and offloading unit (FSO) moored off the coast of Qatar in the Persian Gulf at the Al Shaheen Oil Field.
The vessel was sold to Indian ship breakers, and renamed Mont for its final journey in December 2009. After clearing Indian customs, it was sailed to, and intentionally beached at, Alang, Gujarat, India, to be broken up for scrap.
