B5. Ship Types and Individual VesselsDefinition
ULCC, later Knock Nevis/Mont, scrapped 2010.
Seawise Giant was the largest ship ever built, an ultra-large crude carrier of 564,763 dwt and 458.45 meters length overall, completed by Sumitomo Heavy Industries at Oppama, Japan, in 1979 for Hong Kong owner C.Y. Tung. Her deep draft of about 24.6 meters at full load kept her out of the Suez and Panama canals and the English Channel, restricting her to deepwater crude routes. Iraqi aircraft sank her in shallow Gulf water during the Iran-Iraq War; she was raised, rebuilt, and ran again before serving as a floating storage unit off Qatar. Renamed Happy Giant, Jahre Viking, Knock Nevis, then Mont, she was scrapped at Alang in 2010.
