Knock Nevis

The Knock Nevis is a floating storage and offloading unit (FSO) owned by the Norwegian company Fred Olsen Production.[1] It was previously a supertanker and as such held the record for the world's largest ship. As a tanker the ship was known under the names Seawise Giant, Happy Giant, and Jahre Viking.

The ship has a draft of 24.6 m (81 ft) when fully loaded, which makes it impossible for it to navigate even the English Channel, let alone the man-made canals at Suez and Panama

Knock Nevis was built in 1979 at Sumitomo Heavy Industries's Oppama shipyard as Seawise Giant. The ship was built for a Greek owner who was unable to take delivery of the ship.

A deal was brokered with Hong Kong shipping magnate C. Y. Tung, founder of the shipping line Orient Overseas Container Line. A deal was reached, but Tung required the ship's size be increased by several metres in length and 87,000 metric tons of cargo capacity by jumboisation. Two years later, the vessel was launched and named Seawise Giant.

After the refit, the ship had a capacity of 564,763 metric tons deadweight (DWT), a length overall of 458.45 metres (1,504.1 ft) and a draft of 24.611 metres (80.74 ft). She had 46 tanks, 31,541 square metres (339,500 sq ft) of deck space, and was too large to pass through the English Channel.

From 1979 to 2004, she was owned by the company Loki Stream AS. During this period she flew the Norwegian flag.

The ship was damaged during the Iran–Iraq War while transiting the Strait of Hormuz.[9] As a result she was declared a total loss and laid up in Brunei. At the end of the war, she was towed to the Keppel Company shipyard in Singapore, repaired, and renamed Happy Giant. The ship was sailing again in October 1991.

Jorden Jahre bought the ship in 1991 for the sum of US$39 Million. It was at this stage that the ship was renamed Jahre Viking. It was sold in 2004.

In 2004, she was bought by First Olsen Tankers Pte. Ltd., renamed Knock Nevis and converted into a permanently moored storage tanker. On November 30, 2004 the conversion to FSO was completed.[11] The ship is now permanently moored in the Qatar Al Shaheen oil field in the Persian Gulf, operating as an FSO.


Size record

The Knock Nevis rivals some of the world's largest buildings in size
Size comparison of the Knock Nevis (in red) and other ships and buildings:
The Pentagon, 431m (Light Blue)
USS Enterprise, 342m (Yellow)
RMS Queen Mary 2, 345m (Pink)
Hindenburg, 245m (Green)
Battleship Yamato, 263m (Dark Blue)
Empire State Building, 443m (Grey)In terms of length, Knock Nevis has a length overall of 458.45 m (1,504 ft), making her the largest ship ever constructed. The vessel is longer than many of the world's tallest buildings are tall, for example the Petronas Twin Towers at 452 metres (1,480 ft). She is smaller than the Sears Tower at 527.3 metres (1,730 ft), and Taipei 101 at 509.2 metres (1,671 ft), and considerably smaller than the skyscraper Burj Dubai, at 818 metres (2,680 ft).

Knock Nevis is not the largest ship in all measures, though. By gross tonnage, for example, she ranks fifth, at 236,710 GT, behind the four Batillus-class supertankers, which range from 274,838 to 275,276 GT. These ships are the largest self-propelled objects ever constructed
