Supertanker
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. One of these is the naval replenishment oiler, a tanker which can fuel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Taylor & Francis
Taylor & Francis Group is an international company originating in England that publishes books and academic journals. Its parts include Taylor & Francis, Routledge, F1000 Research or Dovepress.

Bellamya Jiangyouensis
''Bellamya'' was a supertanker, built in 1976 by Chantiers de l'Atlantique at Saint-Nazaire for the French branch of Shell Oil. She was the second Batillus class supertanker. ''Bellamya'', together with her sister ships ''Batillus, Pierre Guillaumat'' and ''Prairial'', was 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. If size is indicated by gross tonnage—a measure of volume—''Bellamya'' was the largest ship ever built. 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 reduced imports by industrialized countries. The cancellation of the orders was seriously considered, but Shel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bellamya Jeffreysi
''Bellamya jeffreysi'' is a species of large freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the family Viviparidae. This species is found in Malawi and Mozambique, in Lake Malawi. Its natural habitat is freshwater lake A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much lar ...s. It is threatened by sedimentation and pollution. The only known conservation measure is that a small area of the lake is protected as a national park.

Molluscan Research
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Bellamya Ecclesi
''Bellamya ecclesi'' is a species of large freshwater snail with a gill and an operculum, an aquatic gastropod mollusc in the family Viviparidae. This species is found in Malawi and Mozambique. Its natural habitat is freshwater lakes. It was previously listed as Endangered in 1996, in 2004 it was changed to Data Deficient, and in 2018 it was changed to Critically Endangered. It is threatened by fishing of Lake Malawi and by lakeside deforestation which may cause sedimentation through soil erosion Soil erosion is the denudation or wearing away of the upper layer of soil. It is a form of soil degradation. This natural process is caused by the dynamic activity of erosive agents, that is, water, ice (glaciers), snow, air (wind), plants, a .... A small portion may be protected by one national park, in which fishing is not allowed. References Viviparidae Gastropods described in 1964 Taxonomy articles created by Polbot {{Viviparidae-stub ...
