Knock Nevis tanker. The oil supertanker Knock Nevis is the largest ship in the world. Comparative data of the tanker Knock Nevis

The tanker, best known as the Knock Nevis, was the largest ship ever built by mankind. During its existence, this supergiant has changed several names: Seawise Giant, Happy Giant, Jahre Viking, Knock Nevis, Mont. Moreover, it managed to change not only the name, but also the dimensions, as well as the scope of its application.

Japanese shipyards received an order to build the largest tanker in the world in 1974. And five years later, in 1979, a gigantic ship, amazing in its size, was launched. But apparently this was not enough for the Greek shipowner. And he ordered an increase in the size of the tanker. The Seawise Giant (as it was then called) was then cut in half and additional sections were added to the middle.

As a result, the dimensions of the world's largest ship took on the following values: length - 458.45 meters, width - 68.86 meters, mass of transported cargo - 564,763 tons, weight of the ship itself - 81,879 tons, steering wheel weight - 230 tons, propeller weight - 50 tons.

As it turned out later, these figures became not only a plus, but also a minus of this giant. When fully loaded, the tanker sank 29.8 meters under water (approximately the height of a nine-story building). Just compare two photographs, the first one shows the ship loaded, the second one shows it empty.

In good weather, the ship could accelerate to 30 km/h, but in this case it would take about 9 kilometers to come to a complete stop. And simply making a turn for a ship of such gigantic size was not easy; the turning radius without the help of tugs was 3.2 km.

In 1981, after all the work to increase the size was completed, Seawise Giant finally began to earn back the money invested in it. His route ran from the oil fields of the Middle East to the United States and back. However, the Iran-Iraq War that was taking place at that time made its own adjustments to the life of the tanker. Since 1986, the ship has been used as a floating terminal for storage and further transshipment of Iranian oil. But this did not save the ship; on May 14, 1988, an Iraqi fighter attacked the Seawise Giant. The tanker received significant damage, lost all the oil on board (it should be noted that the thickness of the sides of the giant ship was only 3.5 cm, nothing else separated thousands of tons of oil from the surrounding sea world) and was out of commission for three years.

During the repairs, the ship had 3,700 tons of damaged steel replaced and its name changed for the first time. Seawise Giant became Happy Giant. However, even before the completion of the restoration work, the tanker changed its owner; it was bought by a Norwegian company for $39 million. Therefore, the ship left the Singapore docks (where the repairs actually took place) under the name Jahre Viking.
The next changes in the life of the giant ship occurred in 2004. The USA and Europe passed laws banning the use of single-walled tankers for transporting oil, and the largest ship in the world found itself out of work. Jahre Viking is renamed Knock Nevis and from now on is used as a floating oil storage facility.

Knock Nevis (in the past also called Seawise Giant, Happy Giant and Jahre Viking) is a Norwegian-flagged supertanker. Its dimensions: 458 meters long and 69 meters wide make it the largest ship in the world.

Built between 1979 and 1981, today it is used as a floating oil storage facility. Characteristics Knock Nevis has a deadweight of 564,763 tonnes, equivalent to 658,362 m³ (4.1 million barrels) of oil.

The length of the tanker is 458.45 meters, width - 68.86 meters, cargo draft - 24.61 meters. The maximum speed is 13 knots, the crew of the vessel is 40 people. The braking distance of the ship is 10.2 kilometers, and the circulation diameter is more than 3.7 kilometers.

The draft when fully loaded does not allow the ship to pass not only the Suez and Panama Canals, but also the English Channel.

Story

The supertanker was built in Japan in the city of Yokosuka by Sumitomo Corporation on the order of a Greek shipowner. However, the still unfinished ship was purchased by Hong Kong shipowner Tung Chao Yung.
It was built under number 1016, and the owner gave it the name Seawise Giant. The new owner ordered an enlargement of the vessel. The ship was cut up and extended, with additional hull sections added increasing the deadweight from the original 480 thousand tons to a record 564,763 tons.

The ship initially sailed between the Middle East and the United States, but in 1986 it began to be used as a floating terminal for storing and transshipping Iranian oil during the Iran-Iraq War. In May 1988, the ship was attacked and heavily damaged by Iraqi aircraft. After the end of the war, the ship, towed to Brunei, was purchased by the Norwegian company KS-company.

The ship was refurbished in Singapore and renamed Happy Giant. However, in 1991, even before the completion of the repairs, KS-company came under the control of the Norwegian shipowner Jørgen Jahre, so the tanker left the shipyard under the name Jahre Viking. KS-company was later purchased by Norwegian shipowner Fred Olsen for his company First Olsen Tankers.

Following the passage of laws in the United States and Europe prohibiting the use of single-sided tankers, the so-called monohull tankers (the Knock Nevis's side is only 3.5 centimeters thick), the ship was converted into a "floating storage unit" in the Dubai docks in March 2004.
Then he once again changed his name to the modern Knock Nevis. Now the ship is permanently located in the area of the Al-Shahim oil field in Qatar as an oil storage facility.

Over the years, the ship in question plied the ocean under the names Seawise Giant, Happy Giant, Jahre Viking, Mont, but he is best known under the name Knock Nevis. And it is this ship that is considered the largest ship in the history of navigation.

In 2009, the tanker once again changed its owner and name. Mont

Here's what they write about the largest ship on the grandstroy blog.

The tanker best known as Knock Nevis, was the largest ship ever built by mankind. During its existence, this supergiant has changed several names: Seawise Giant, Happy Giant, Jahre Viking, Knock Nevis, Mont. Moreover, it managed to change not only the name, but also the dimensions, as well as the scope of its application.

Construction order the largest tanker in the world Japanese shipyards received it in 1974. And five years later, in 1979, a gigantic ship, amazing in its size, was launched. But apparently this was not enough for the Greek shipowner. And he ordered an increase in the size of the tanker. Then, Seawise Giant(as it was called then) was cut in half and additional sections were added to the middle.

Eventually, dimensions of the world's largest ship The following values were adopted: length - 458.45 meters, width - 68.86 meters, mass of transported cargo - 564,763 tons, weight of the vessel itself - 81,879 tons, steering wheel weight - 230 tons, propeller weight - 50 tons.

It is not surprising that with such a draft, the tanker could not navigate either the Suez or Panama Canals (the length and width would also not allow using the Panama Canal; the Seawise Giant exceeds the maximum permissible dimensions of the locks by 1.5 times).

During the repairs, the ship had 3,700 tons of damaged steel replaced and its name changed for the first time. Seawise Giant turned into Happy Giant. However, even before the completion of the restoration work, the tanker changed its owner; it was bought by a Norwegian company for $39 million. Therefore, the ship left the Singapore docks (where the repairs actually took place) under the name Jahre Viking.

The next changes in the life of the giant ship occurred in 2004. The USA and Europe passed laws banning the use of single-walled tankers for transporting oil, and the largest ship in the world found itself out of work. Jahre Viking renamed to Knock Nevis and since that time it has been used as a floating oil storage facility.

In the photo, Knock Nevis is the largest ship in the history of navigation.

That was the name of the ship now, setting off on its last voyage. His destination is India, or rather the world famous Alang ship graveyard. There, over the course of several months, the tanker is cut into pieces and sent for smelting. The only thing left of the world's largest ship is its 36-ton anchor, which is kept in the Hong Kong Maritime Museum.

Oil has long become the most sensitive nerve of the entire world industry. Often, it is most profitable to transport “black gold” not by land, but by water. The route taken by ships of this type is called “oil”. Already in the 19th century, when coal was the main raw material, crude oil was transported in wooden and zinc barrels in special holds sailing ships intended for oil.

The most the first sea tanker for transporting oil in a tank, the walls of which were lining, it became “ Atlantic", built in 1863. This type tanker, the reservoir for the liquid cargo is the hull, which has survived to this day. By the beginning of the First World War sea tankers already accounted for 3% of the world's merchant fleet.

The demand for oil is growing every year. This process is associated with the continuous development of heavy industry and the emergence of an increasing number of motor vehicles. Accordingly, the scale is increasing and the requirements for its transportation are becoming more stringent. I doubt that there are any whose size and displacement would have the same rapid development trend as tankers.

Shipbuilding development oil tankers takes into account the features and advantages supertankers, since when transporting oil on a ship that can hold more than 100,000 tons of oil, transportation costs are not much higher than when using a tanker with a carrying capacity of 16,000 tons. Today large tankers And supertankers fully automated and operated by a relatively small crew. Even the longest transportation of valuable cargo is much cheaper than when operating a conventional vessel. And one of these is “ Knock Nevis».

The history of this sea vessel began in Japan in 1976 (some sources indicate 1975) at the shipyards of the company " Sumitomo Heavy Industries." Then oil tanker "Knock Nevis"“born” under the modest serial number 1016 and was not that big. Soon the cargo ship was sold to a certain Greek shipowner, who gave oil tanker first real name " Seawise Giant". Its carrying capacity was 480,000 tons (typical modern oil tankers hold 280,000 tons). Three years later, the cargo ship was sold to a new owner, who ordered an enlargement. Japanese shipbuilders cut and extended tanker, which took quite a lot of time. Finally in 1981 supertanker was ready to go again. Welded additional sections of the hull increased its deadweight to 564,763 tons.

Supertanker "Knock Nevis" could easily take on board the Empire State Building and the Eiffel Tower. But its cargo is $195 million worth of oil. Huge ship has outlived several owners and is already bearing its fourth name " Knock Nevis". They shot him with rockets and cut him in half. And yet - for more than 20 years he remains the most big by ship on the planet. During my life supertanker changed several owners and changed names more than once: first - to “ Happy Giant", then to " Jahre Viking".
