Batillus Class Supertankers
The ''Batillus''-class supertankers were a class of supertanker ships built in France in the late 1970s, with four ships of this class built between 1976 and 1979. Three of the ships were scrapped after less than ten years of oil transport service each, with the fourth one scrapped in 2003. All four tankers were built in the ''Bassin C'' dock of the Chantiers de l'Atlantique shipyards at Saint Nazaire, France.

Batillus
''Batillus'' was a supertanker built in 1976 by Chantiers de l'Atlantique at Saint-Nazaire for the French branch of Shell Oil. The first vessel of the Batillus class, she was, together with her sister ships ''Bellamya, Pierre Guillaumat'' and ''Prairial'', one of the biggest ships in the world, surpassed in size only by ''Seawise Giant'' (later ''Jahre Viking, Happy Giant'' and ''Knock Nevis'') built in 1976, and extended in 1981, although the four ships of the Batillus class had a larger gross tonnage. History The contract to build the Batillus class supertankers was signed on April 6, 1971, and the first sheet metal was cut in January 1975. Meanwhile, the oil shock caused by the Yom Kippur War in October 1973, resulted in higher oil prices and reduction of imports from industrialized countries. The cancellation of the order had been seriously considered, but Shell concluded that it was better to continue, mostly to not put the shipyard in very difficult position with withdraw ...

Oil Tankers
An oil tanker, also known as a petroleum tanker, is a ship designed for the bulk transport of oil or its products. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Oil tankers are often classified by their size as well as their occupation. The size classes range from inland or coastal tankers of a few thousand metric tons of deadweight (DWT) to the mammoth ultra large crude carriers (ULCCs) of . Tankers move approximately of oil every year.UNCTAD 2006, p. 4. Second only to pipelines in terms of efficiency,Huber, 2001: 211. the average cost of transport of crude oil by tanker amounts to only US. Some specialized types of oil tankers have evolved.

List Of World's Longest Ships
The world's longest ships are listed according to their overall length (LOA), which is the maximum length of the vessel measured between the extreme points in fore and aft. In addition, the ships' deadweight tonnage (DWT) and/or gross tonnage (GT) are presented as they are often used to describe the size of a vessel. The ships are listed by type. Only ship types for which there exist a ship longer than are included. For each type, the list includes current record-holders either as individual ships, ship classes or standard designs, up to four runner-ups, and all longer ships that have been scrapped.

Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Main Deck
The main deck of a ship is the uppermost complete deck extending from bow to stern. A steel ship's hull may be considered a structural beam with the main deck forming the upper flange of a box girder and the keel forming the lower strength member. The main deck may act as a tension member when the ship is supported by a single wave amidships, or as a compression member Compression members are structural elements that are pushed together or carry a load; more technically, they are subjected only to axial compressive forces. That is, the loads are applied on the longitudinal axis through the centroid of the memb ... when the ship is supported between waves forward and aft. References {{reflist Nautical terminology ...

List Of Tallest Buildings In The World
This list of tallest buildings includes skyscrapers with continuously occupiable floors and a height of at least . Non-building structures, such as towers, are not included in this list (for these, see ''List of tallest buildings and structures''). History Historically, the world's tallest man-made structure was the Great Pyramid of Giza in Egypt, which held the position for over 3800 years until the construction of Lincoln Cathedral in 1311. The Strasbourg Cathedral in France, completed in 1439, was the world's tallest building until 1874. The first skyscraper was pioneered in Chicago with the Home Insurance Building in 1885. The United States would hold the position of the world's tallest building throughout the 20th century until 1998, when the Petronas Towers were completed. Since then, two other buildings have gained the title: Taipei 101 in 2004 and Burj Khalifa in 2010.

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Deadweight Tonnage
Deadweight tonnage (also known as deadweight; abbreviated to DWT, D.W.T., d.w.t., or dwt) or tons deadweight (DWT) is a measure of how much weight a ship can carry. It is the sum of the weights of cargo, fuel, fresh water, ballast water, provisions, passengers, and crew. DWT is often used to specify a ship's maximum permissible deadweight (i.e. when it is fully loaded so that its Plimsoll line is at water level), although it may also denote the actual DWT of a ship not loaded to capacity. Definition Deadweight tonnage is a measure of a vessel's weight carrying capacity, not including the empty weight of the ship. It is distinct from the displacement (weight of water displaced), which includes the ship's own weight, or the volumetric measures of gross tonnage or net tonnage (and the legacy measures gross register tonnage and net register tonnage). Deadweight tonnage was historically expressed in long tonsOne long ton (LT) is but is now usually given internationally in t ...

Gross Tonnage
Gross tonnage (GT, G.T. or gt) is a nonlinear measure of a ship's overall internal volume. Gross tonnage is different from gross register tonnage. Neither gross tonnage nor gross register tonnage should be confused with measures of mass or weight such as deadweight tonnage or Displacement (ship), displacement. Gross tonnage, along with net tonnage, was defined by the ''International Convention on Tonnage Measurement of Ships, 1969'', adopted by the International Maritime Organization (IMO) in 1969, and came into force on 18 July 1982. These two measurements replaced gross register tonnage (GRT) and net register tonnage (NRT). Gross tonnage is calculated based on "the moulded volume of all enclosed spaces of the ship" and is used to determine things such as a ship's manning regulations, safety rules, registration fees, and port dues, whereas the older gross register tonnage is a measure of the volume of only certain enclosed spaces.

Saint Nazaire
Saint-Nazaire (; ; Gallo language, Gallo: ''Saint-Nazère/Saint-Nazaer'') is a Communes of France, commune in the Loire-Atlantique Departments of France, department in western France, in traditional Brittany. The town has a major harbour on the right bank of the Loire estuary, near the Atlantic Ocean. The town is at the south of the second-largest swamp in France, called "la Brière". Given its location, Saint-Nazaire has a long tradition of fishing and shipbuilding. The Chantiers de l'Atlantique, one of the largest shipyards in the world, constructed notable ocean liners such as , , and the cruise ship , the largest passenger ship in the world until 2022. Saint-Nazaire was a small village until the industrial era, Industrial Revolution but became a large town in the second half of the 19th century, thanks to the construction of railways and the growth of the seaport. Saint-Nazaire progressively replaced upstream Nantes as the main haven on the Loire estuary. As a major submari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
