The Years Viking was an oil tanker of the ULCC (Ultra Large Crude Oil Carrier) class and became the longest ship on earth when it was extended by 81 meters in 1980. The largest ship ever built in one piece, however, was the tanker Pierre Guillaumat, which was scrapped in 1983 .
From 2004 to 2009 the tanker was used as a floating crude oil storage facility under the name Knock Nevis .
Technical specifications
The years Viking was 458.45 meters (originally 377.45 meters) above sea level. A. long, 68.80 meters wide, and when fully loaded she had a draft of 24.61 meters. The side height was 29.80 meters.
The tanker was measured with 190,000 GT , after the extension from 1980 with 238,000 GT and during the period from 1990 to 2004 (under the Norwegian flag) with 260,815 GT , most recently it was 260,941 GT. Its carrying capacity was 420,000 dwt and increased after the extension on to 564,736 dwt. The Viking years held 4.3 million barrels = 652 million liters of crude oil .
The drive system consisted of two water-tube high-pressure boilers and a steam turbine from the manufacturer Sumitomo Stal- Laval, type AP 50/85. The max. Continuous output was 36,745 kW (50,000 hp). The speed at full draft was 15.8 knots with a shaft speed of 85 rpm.
history
The ship, which was ordered in 1972 by a Greek shipowner as a 420,000 tdw tanker from Sumitomo Heavy Industries , Oppama Yard , Japan , was laid down and undocked in 1975 under the name Porthos . It was completed in 1976, but was not accepted by the client due to alleged technical problems. Since no other buyer could be found, the shipyard was launched as Oppama .
In 1979 the Hong Kong shipowner CY Tung bought the ship and it was renamed Seawise Giant (CY's Giant - a play on words with reference to the owner). After just one ride from Japan to the Persian Gulf and back, it was in a three-month conversion period to December 1980 with Nippon Kokan - shipyard in Tsu , Japan, 81-meter section extended by one. The carrying capacity increased by 144,000 dwt to 564,000 dwt. On May 14, 1988 it was shot at by the Iraqi Air Force on a passage through the Strait of Hormuz during the Iran-Iraq war . The ship suffered severe damage and was towed into the Bay of Brunei . At this point it was barely buoyant and therefore not ready for use.
After a layover as Happy Giant , the ship was towed to Singapore at the end of the war , where it was given a general overhaul at the Keppel Shipyard in October 1991 . The hull had been acquired by the Norwegian shipowner Anders Jahre . It was renamed Years Viking . A new, identical deckhouse was constructed for the general overhaul. In addition, 3200 tons of steel and 32 kilometers of pipes were used. The ship was painted red. The cost of the overhaul was $ 60 million. In 1995 the ship came fully loaded to France for the first time to the deep-water tanker oil terminal in Cape d'Antifer .
In autumn 2003 the year Viking was sold by the owner years to the shipping company Fred Olsen Tankers . Use as a normal crude oil tanker was no longer possible from January 2004 due to stricter environmental and safety regulations, as the ship was not a double-hulled tanker . In March 2004, the renovation work on the Years Viking began in the Dubai Drydocks . In order to be able to use them as a floating intermediate storage facility for crude oil, the hull and the tanks were overhauled. In addition, the entire structure of the ship was changed and a helicopter landing platform was added. The work was completed in September 2004. Under the name Knock Nevis, the ship performed its service as an FSO (interim storage facility for crude oil) in the Al Shaheen oil field in Qatar .
In December 2009, the tanker began its journey under the new name of Mont under the flag of Sierra Leone to Bhavnagar , where the final formalities were completed in Alang before being scrapped . In January 2010 the ship was put on the beach for demolition in Alang. Originally the ship was supposed to be dismantled in China, but was then sold to India.
Former area of application
Due to their gigantic dimensions, the area of application of the Viking years was very limited. For example, she needed a stopping distance of more than six kilometers, was unable to cross the Panama or Suez Canal and, moreover, was unable to navigate the English Channel , which was not due to its size but rather to its poor maneuverability. Due to its great draft , it was only able to call at a minimal number of world ports and was therefore loaded and unloaded at "offshore mooring rigs".
