Batillus-class Supertankers
The ''Batillus''-class supertankers were a class of Tanker (ship), 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 Ship breaking, 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 , she was, together with her sister ships , and ''Hellas Fos, Prairial'', one of the biggest ships in the world, surpassed in size only by (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. She was sold for Ship breaking, scrap in 1985 after a prolonged downturn in the oil market made her economically impractical. History The contract to build the ''Batillus''-class supertankers was signed on 6 April 1971, and the first sheet metal was cut in January 1975. Meanwhile, the 1973 oil crisis, oil shock caused by the Yom Kippur War in October 1973, resulted in higher Petroleum, oil prices and reduction of imports from industrialized countries. The cancellation of the order had been seriously considered, but Sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Fresh water or freshwater is any naturally occurring liquid or frozen water containing low concentrations of dissolved salt (chemistry), salts and other total dissolved solids. The term excludes seawater and brackish water, but it does include ..., 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 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.

Propeller
A propeller (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 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 stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Globtik Tokyo
''Globtik Tokyo'' was one of three oil tankers in its class. At the time her keel was laid in 1972 she was the largest supertanker in the world at 378.85 meters (1,242 feet) and 483,684 tonnes (dwt). She held that distinction until 1973 when her sister ship the ''Globtik London'' was launched. Identical in size the ''London'' was larger by 276 dead weight tonnes (dwt). Both ships had a hold capacity of 580 million liters (3.65 million US barrels).E. Abranson (1976). ''Ships of the High Seas'', Eurobook Ltd. pp.119-120. Owned by Globtik Tankers, London they were built by Ishikawajima Harima Heavy Industries in Kure Japan, now known as IHI Corporation. Both ships have been retired from service and broken up for scrap, the ''London'' in 1985 and the ''Tokyo'' in 1986. The third and largest ship in this class was the 484276 dwt ''Nissei Maru'' owned by Tokyo Tankers built in 1975 and scrapped in 2003.

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

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 In physics, mathematics, engineering, and related fields, a wave is a propagating dynamic disturbance (change from List of types of equilibrium, equilibrium) of one or more quantities. ''Periodic waves'' oscillate repeatedly about an equilibrium ... amidships, or as a compression member when the ship is supported between waves forward and aft.

List Of Tallest Buildings In The World
This is a list of the tallest buildings. Tall buildings, such as skyscrapers, are intended here as enclosed structures with continuously occupiable floors and a height of at least . Such definition excludes non-building structures, such as towers. History Historically, the world's tallest man-made structure was the Great Pyramid of Giza in Egypt, which held the position for over 3,800 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 building considered to be a skyscraper was the Home Insurance Building, built in Chicago in 1885. The United States would remain the location 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 2009. Since the beginning of the 21st century, the Middle East, China, and Southe ...

Length Overall
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 reported. 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. 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.
