The TTSeawise Giant—earlier Oppama; later Happy Giant, Jahre Viking, Knock Nevis, and Mont—was a ULCC supertanker and the longest self-propelled ship in history, built in 1974–1979 by Sumitomo Heavy Industries in Yokosuka, Kanagawa, Japan. She possessed the greatest deadweight tonnage ever recorded. Fully laden, her displacement was 657,019 tonnes.
The heaviest self-propelled ship of any kind, with a laden draft of 24.6 m (81 ft) and a length of 1,504.10 ft, she was incapable of navigating the English Channel,[5] the Suez Canal or the Panama Canal. Overall, she is generally considered the largest self-propelled ship ever built.[6][7] In 2013 her overall length was surpassed by 30 m by the floating liquified natural gas installation Shell Prelude (FLNG), a monohull barge design 488 m (1,601 ft) long and 600,000 tonnes displacement. Seawise Giant's engines were powered by Ljungström turbines.
She was damaged in 1988 during the Iran–Iraq War, but was later repaired and restored to service.[citation needed] The vessel was converted to a floating storage and offloading unit (FSO) in 2004, moored off the coast of Qatar in the Persian Gulf at the Al Shaheen Oil Field.[8]
The vessel was sold to Indian ship breakers, and renamed Mont for a final journey in December 2009. After clearing Indian customs, the ship sailed to Alang Ship Breaking Yard, Alang, Gujarat, where she was beached for scrapping, which was completed in 2010.[8][9]
