Knock Nevis

The Knock Nevis is a massive ship, currently used as a floating storage and offloading unit (FSO). Owned by the Norwegian company Fred Olsen Production,[1] she was previously a supertanker and still holds the record as the longest ship ever built.

When plying the sea, the vessel had a fully laden draft of 24.6 m (81 ft), rendering it unable to navigate the English Channel, the Suez Canal or the Panama Canal when its load was up to capacity.[6] As a tanker she was known as the Seawise Giant, Happy Giant, and Jahre Viking.
