Merchantmen
A merchant ship, merchant vessel, trading vessel, or merchantman is a watercraft that transports cargo or carries passengers for hire. This is in contrast to pleasure craft, which are used for personal recreation, and naval ships, which are used for military purposes. They come in a myriad of sizes and shapes, from inflatable dive boats in Hawaii, to 5,000-passenger casino vessels on the Mississippi River, to tugboats plying New York Harbor, to oil tankers and container ships at major ports, to passenger-carrying submarines in the Caribbean. Many merchant ships operate under a "flag of convenience" from a country other than the home of the vessel's owners, such as Liberia and Panama, which have more favorable maritime laws than other countries. The Greek merchant marine is the largest in the world. Today, the Greek fleet accounts for some 16 per cent of the world's tonnage; this makes it currently the largest single international merchant fleet in the world, albei ...

Submarine
A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or informally to refer to remotely operated vehicles and Autonomous underwater vehicle, robots, or to medium-sized or smaller vessels (such as the midget submarine and the wet sub). Submarines are referred to as ''boats'' rather than ''ships'' regardless of their size. Although experimental submarines had been built earlier, submarine design took off during the 19th century, and submarines were adopted by several navies. They were first used widely during World War I (1914–1918), and are now used in many navy, navies, large and small. Their military uses include: attacking enemy surface ships (merchant and military) or other submarines; aircraft carrier protection; Blockade runner, blockade running; Ballistic missile submarine, nuclear deterrenc ...

Flags Of Convenience
Flag of convenience (FOC) refers to a business practice whereby a ship's owners register a merchant ship in a ship register of a country other than that of the ship's owners, and the ship flies the civil ensign of that country, called the flag state.Bernaert, 2006, p. 104. The term is often used pejoratively, and although common, the practice is sometimes regarded as contentious. Each merchant ship is required by international law to be registered in a registry created by a country,ICFTU et al., 2002, p. 7. and a ship is subject to the laws of that country, which are used also if the ship is involved in a case under admiralty law. A ship's owners may elect to register a ship in a foreign country so as to avoid the regulations of the owners' country, which may, for example, have stricter safety standards. They may also select a jurisdiction to reduce operating costs, avoiding higher taxes in the owners' country and bypassing laws that protect the wages and working conditions of ...

Wenceslas Hollar - A Flute (State 2)
Wenceslaus, Wenceslas, Wenzeslaus and Wenzslaus (and other similar names) are Latinized forms of the Slavic names#In Slovakia and Czech_Republic, Czech name Václav. The other language versions of the name are , , , , , , among others. It originated as a Latin spelling for Czech rulers. It is a Slavic dithematic name (of two lexemes), derived from the Slavic words ''veli/vyache/więce/više'' ("great(er), large(r)"), and ''slava'' ("glory, fame") – both very common in Slavic names – and roughly means "greater glory". Latinised name Wenceslaus corresponds to several West Slavic, Lechitic languages, Lechitic given names, such as ''Wieceslaw'', ''Wiecejslav'', ''Wieńczysław''/''Vienceslav'', ''Vjenceslav'', ''Węzel'', ''Wacław'' and a few more. People named Wenceslaus or spelling variations thereof include: * Wenceslaus I, Duke of Bohemia (907–935 or 929), saint and subject of the Christmas carol "Good King Wenceslas" * Wenceslaus II, Duke of Bohemia (died 1192) * Wencesl ...

Navy
A navy, naval force, military maritime fleet, war navy, or maritime force is the military branch, branch of a nation's armed forces principally designated for naval warfare, naval and amphibious warfare; namely, lake-borne, riverine, littoral zone, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface Naval ship, ships, amphibious warfare, amphibious ships, submarines, and seaborne naval aviation, aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is Power projection, projection of force into areas beyond a country's shores (for example, to protect Sea lane, sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of a navy also may incorporate nuclear deterrence by use of submarine-launche ...

Motor Tanker
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. One of these is the naval replenishment oiler, a tanker which can fuel a moving vess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Motorship
A motor ship or motor vessel is a ship propelled by an internal combustion engine, usually a diesel engine. The names of motor ships are often prefixed with MS, M/S, MV or M/V. Engines for motorships were developed during the 1890s, and by the early 20th century, motorships began to cross the waters. History The first diesel-powered motorships were launched in 1903: the Russian (the first equipped with diesel-electric transmission) and French ''Petite-Pierre''. There is disagreement over which of the two was the first. See also * Gas turbine ship (GTS) – prefix for a jet-engine/turbine-propelled ship * Steamship (SS) – a steamship is a ship propelled by a steam engine or steam turbine. The name of steam ships are often prefixed with SS or S/S * Royal Mail Ship (RMS) – Royal Mail Ship * Ship prefix A ship prefix is a combination of letters, usually abbreviations, used in front of the name of a civilian or naval ship that has historically served numerous purposes, ...

Liquefied Petroleum Gas
Liquefied petroleum gas, also referred to as liquid petroleum gas (LPG or LP gas), is a fuel gas which contains a flammable mixture of hydrocarbon gases, specifically propane, Butane, ''n''-butane and isobutane. It can also contain some propylene, butylene, and isobutylene/Isobutylene, isobutene. LPG is used as a fuel gas in HVAC, heating appliances, cooking equipment, and vehicles, and is used as an aerosol propellant and a refrigerant, replacing chlorofluorocarbons in an effort to reduce the damage it causes to the ozone layer. When specifically used as a vehicle fuel, it is often referred to as autogas or just as Autogas#Terminology variations and confusion, gas. Varieties of LPG that are bought and sold include mixes that are mostly propane (), mostly butane (), and, most commonly, mixes including both propane and butane. In the northern hemisphere winter, the mixes contain more propane, while in summer, they contain more butane. In the United States, mainly two grad ...

Gas Carrier
A gas carrier, gas tanker, LPG carrier, or LPG tanker is a ship designed to transport Liquefied petroleum gas, LPG, LNG, CNG, or liquefied chemical gases in Bulk liquids, bulk. Gases are kept refrigerated onboard the ships to enable safe carriage in liquid and vapour form and for this reason, gas carriers usually have onboard refrigeration systems. Design and construction of all gas carriers operating internationally is regulated by the International Maritime Organization through the International Code of the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk. There are various types of gas carriers, depending on the type of gas carried and the type of containment system, two of the most common being the Moss Type B (spherical) type and the membrane (typically GTT) type. Types Fully pressurized gas carrier The seaborne transport of liquefied gases began in 1934 when a major international company put two combined oil/LPG tankers into operation. The ships, basi ...

Liquefied Natural Gas
Liquefied natural gas (LNG) is natural gas (predominantly methane, CH4, with some mixture of ethane, C2H6) that has been cooled to liquid form for ease and safety of non-pressurized storage or transport. It takes up about 1/600th the volume of natural gas in the gaseous state at standard temperature and pressure. LNG is odorless, Transparency and translucency, colorless, toxicity, non-toxic and Corrosive substance, non-corrosive. Hazards include flammability after vaporization into a gaseous state, freezing and asphyxia. The Liquefaction of gases, liquefaction process involves removal of certain components, such as dust, acid gases, helium, water, and heavy hydrocarbons, which could cause difficulty downstream. The natural gas is then condensation, condensed into a liquid at close to atmospheric pressure by cooling it to approximately ; maximum transport pressure is set at around (gauge pressure), which is about 0.25 times atmospheric pressure at sea level. The gas extracted ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cable Layer
A cable layer or cable ship is a deep-sea ship, vessel designed and used to lay underwater cables Submarine communications cable, for telecommunications, Submarine power cable, for electric power transmission, military, or other purposes. Cable ships are distinguished by large cable sheaves for guiding cable over Bow (watercraft), bow or stern or both. Bow sheaves, some very large, were characteristic of all cable ships in the past, but newer ships are tending toward having stern sheaves only, as seen in the photo of CS ''Cable Innovator'' at the Port of Astoria on this page. The names of cable ships are often preceded by "C.S." as in CS ''Long Lines''. The first transatlantic telegraph cable was laid by cable layers in 1857 to 1858. It briefly enabled telecommunication between Europe and North America before misuse resulted in failure of the line. In 1866 the successfully laid two transatlantic cables, securing future communication between the continents. Modern cable ships ...

British Merchant Navy
The British Merchant Navy is the collective name given to British civilian ships and their associated crews, including officers and ratings. In the UK, it is simply referred to as the Merchant Navy or MN. Merchant Navy vessels fly the Red Ensign and the ships and crew are regulated by the Maritime and Coastguard Agency (MCA), a specialist agency of the UK Department of Transport. British merchant ships are registered under the UK or Red Ensign group ship registries. British Merchant Navy deck officers and ratings are certificated and trained according to STCW Convention and the syllabus of the Merchant Navy Training Board in maritime colleges and other training institutes around the UK. King George V bestowed the title of "Merchant Navy" on the British merchant shipping fleets following their service in the First World War; a number of other nations have since adopted the title. Previously it had been known as the Mercantile Marine or Merchant Service, although the term "Merch ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
