Seawise Giant
TT Seawise Giant—formerly Oppama; later Happy Giant, Jahre Viking, Knock Nevis, and Mont—was a ULCC supertanker and the longest self-propelled ship in history. It was built in 1974–1979 by Sumitomo Heavy Industries in Yokosuka, Kanagawa, Japan. Seawise Giant's engines were powered by Ljungström turbines. The ship possessed the greatest deadweight tonnage ever recorded. Fully laden, her displacement was 657,019 tonnes.
At the time she was built, she was the heaviest self-propelled ship of any kind. With a laden draft of 24.6 m (81 ft) and a length of 458.45 m (1,504.1 ft), the ship was incapable of navigating the English Channel, the Suez Canal or the Panama Canal. She is generally considered the largest self-propelled ship ever built. In 2013, her overall length was surpassed by 30 m (98 ft) by the floating liquefied natural gas (FLNG) installation Shell Prelude, a monohull barge design 488 m (1,601 ft) long with 600,000 tonnes displacement..
The ship was damaged in an airstrike in 1988 during the Iran–Iraq War but later repaired and restored to service. The vessel was moored off the coast of Qatar in the Persian Gulf at the Al Shaheen Oil Field in 2004 and converted to a floating storage and offloading (FSO) unit.
Seawise Giant was sold to Indian ship breakers and renamed Mont for her final journey in December 2009. After clearing Indian customs, the ship sailed to Alang Ship Breaking Yard in Alang, Gujarat and beached for scrapping, which was completed in 2010.
Seawise Giant was ordered in 1974 and delivered in 1979 by Sumitomo Heavy Industries, Ltd. (S.H.I.) at Oppama shipyard in Yokosuka, Kanagawa, Japan, as a 418,611-ton Ultra Large Crude Carrier (ULCC). The vessel remained unnamed for a long time, and was identified by her hull number, 1016. During sea trials, 1016 exhibited severe vibration problems while going astern. The unknown Greek owner refused to take delivery and the vessel was subject to a lengthy arbitration proceeding. Following settlement, the vessel was sold and named Oppama by S.H.I.
The shipyard exercised its right to sell the vessel and a deal was brokered with Hong Kong Orient Overseas Container Line founder C. Y. Tung to lengthen the ship by several metres and add 146,152 tonnes of cargo capacity through jumboisation. Two years later the ship was relaunched as Seawise Giant. "Seawise", a pun on "C.Y.'s", was used in the names of other ships owned by C.Y. Tung, including Seawise University.
After the refit, the ship had a capacity of 564,763 tonnes deadweight (DWT), a length overall of 458.45 m (1,504.1 ft) and a draft of 24.611 m (80.74 ft). She had 46 tanks, and 31,541 m2 (339,500 sq ft) of deck space. When Seawise Giant was fully loaded, her 25 meter/81 foot draft was too deep to safely navigate the relatively shallow English Channel. The rudder weighed 230 tons, and the propeller weighed 50 tons.
Seawise Giant was damaged in 1988 during the Iran–Iraq War by an Iraqi Air Force attack while anchored off Larak Island, Iran on 14 May 1988 while carrying Iranian crude oil. The ship was struck by Iraqi French made Exocet missile launched from aircraft. Fires ignited aboard the ship, spreading to the oil leaked into the surrounding water and blazing out of control. Contrary to some later internet reports the vessel did not sink; images of the burnt-out but still afloat vessel have been published online.
