SS Black Osprey
SS ''Black Osprey'' was a cargo ship for the American Diamond Lines and the British Cairn Line. She was formerly known as SS ''West Arrow'' when she was launched for the United States Shipping Board (USSB) during World War I. The ship was inspected by the United States Navy for possible use as USS ''West Arrow'' (ID-2585) but was neither taken into the Navy nor ever commissioned under that name. ''West Arrow'' was built in 1918 for the USSB, as a part of the ''West'' boats, a series of steel- hulled cargo ships built on the West Coast of the United States for the World War I war effort. Information about her early career is largely absent, but by the 1920s, news reports revealed that the ship was sailing on the North Atlantic. By the mid-1920s, ''West Arrow'' was sailing for American Diamond on their cargo service to Rotterdam and Antwerp. In 1935, American Diamond changed the ship's name to ''Black Osprey'' and the ship continued in Rotterdam service. After the outbreak of ...

West Coast Of The United States
The West Coast of the United States, also known as the Pacific Coast, Pacific states, and the western seaboard, is the coastline along which the Western United States meets the North Pacific Ocean. The term typically refers to the contiguous U.S. states of California, Oregon, and Washington, but sometimes includes Alaska and Hawaii, especially by the United States Census Bureau as a U.S. geographic division. Definition There are conflicting definitions of which states comprise the West Coast of the United States, but the West Coast always includes California, Oregon, and Washington as part of that definition. Under most circumstances, however, the term encompasses the three contiguous states and Alaska, as they are all located in North America. For census purposes, Hawaii is part of the West Coast, along with the other four states. ''Encyclopædia Britannica'' refers to the North American region as part of the Pacific Coast, including Alaska and British Columbia. Although ...

The Washington Post
''The Washington Post'' (also known as the ''Post'' and, informally, ''WaPo'') is an American daily newspaper published in Washington, D.C. It is the most widely circulated newspaper within the Washington metropolitan area and has a large national audience. Daily broadsheet editions are printed for D.C., Maryland, and Virginia. The ''Post'' was founded in 1877. In its early years, it went through several owners and struggled both financially and editorially. Financier Eugene Meyer purchased it out of bankruptcy in 1933 and revived its health and reputation, work continued by his successors Katharine and Phil Graham (Meyer's daughter and son-in-law), who bought out several rival publications. The ''Post'' 1971 printing of the Pentagon Papers helped spur opposition to the Vietnam War. Subsequently, in the best-known episode in the newspaper's history, reporters Bob Woodward and Carl Bernstein led the American press's investigation into what became known as the Waterga ...

13th Naval District
The naval district was a U.S. Navy military and administrative command ashore. Apart from Naval District Washington, the Districts were disestablished and renamed Navy Regions about 1999, and are now under Commander, Naval Installations Command (CNIC). They were established for the purpose of decentralizing the Navy Department's functions with respect to the control of the coastwise sea communications and the shore activities outside the department proper, and for the further purpose of centralizing under one command: : (a) For military coordination, all naval activities, and : (b) For administrative coordination, all naval activities with specific exceptions, within the district and the waters thereof. The limits of the naval districts are laid down in article 1480, Navy Regulations. Those limits extend to seaward so far as to include the coastwise sea lanes (art. 1486 (1), Navy Regulations). "Each naval district shall be commanded by a designated commandant, who is the di ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Screw 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] |
Steam Turbine
A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the use of multiple stages in the expansion of the steam, which results in a closer approach to the ideal reversible expansion process. Because the turbine generates rotary motion, it can be coupled to a generator to harness its motion into electricity. Such turbogenerators are the core of thermal power stations which can be fueled by fossil- ... [...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, 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 i ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

Keel Laying
Laying the keel or laying down is the formal recognition of the start of a ship's construction. It is often marked with a ceremony attended by dignitaries from the shipbuilding company and the ultimate owners of the ship. Keel laying is one of the four specially celebrated events in the life of a ship; the others are launching, commissioning and decommissioning. In earlier times, the event recognized as the keel laying was the initial placement of the central timber making up the backbone of a vessel, called the keel. As steel ships replaced wooden ones, the central timber gave way to a central steel beam. Modern ships are most commonly built in a series of pre-fabricated, complete hull sections rather than around a single keel. The event recognized as the keel laying is the first joining of modular components, or the lowering of the first module into place in the building dock. It is now often called "keel authentication", and is the ceremonial beginning of the ship's li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barry, Vale Of Glamorgan
Barry ( cy, Y Barri; ) is a town in the Vale of Glamorgan, Wales, on the north coast of the Bristol Channel approximately south-southwest of Cardiff. Barry is a seaside resort, with attractions including several beaches and the resurrected Barry Island Pleasure Park. According to Office for National Statistics 2016 estimate data, the population of Barry was 54,673. Once a small village, Barry has absorbed its larger neighbouring villages of Cadoxton and Barry Island, and now, Sully. It grew significantly from the 1880s with the development of Barry Docks, which in 1913 was the largest coal port in the world. Etymology The origin of the town's name is disputed. It may derive from the sixth-century Saint Baruc who was buried on Barry Island where a ruined chapel was dedicated to him. Alternatively, the name may derive from Welsh ', meaning "hill, summit". The name in Welsh includes the definite article. History Early history The area now occupied by Barry has seen hum ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Isthmian Line
The Isthmian Steamship Company was a shipping company founded by US Steel in 1910. Isthmian Steamship was the brainchild of US Steel President James A. Farrell, who had connections with the maritime industry through his father's trade as a ship's master. Farrell realized that US Steel could save substantial sums of money by owning its own fleet of freighters, rather than chartering cargo space from other companies. Farrell named the company after the Isthmus of Panama, in honour of America's recent construction achievement, the Panama Canal. Farrell headquartered Isthmian Steamship in London, partly in order to take advantage of Great Britain's respected name in the industry, and partly to benefit from Britain's long history of maritime experience. Management of the company was assigned to the British Federal Steam Navigation Co Ltd, a company which traced its own origins back as far as 1782 with the British East India Company. The US end of Farrell's new company was managed b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Chartering
Chartering is an activity within the shipping industry whereby a shipowner hires out the use of their vessel to a charterer. The contract between the parties is called a charterparty (from the French ''"charte partie"'', or "parted document"). The three main types of charter are: demise charter, voyage charter, and time charter. The charterer In some cases a charterer may own cargo and employ a shipbroker to find a ship to deliver the cargo for a certain price, called freight rate. Freight rates may be on a per-ton basis over a certain route (e.g. for iron ore between Brazil and China), in Worldscale points (in case of oil tankers) or alternatively may be expressed in terms of a total sum - normally in U.S. dollars - per day for the agreed duration of the charter. A charterer may also be a party without a cargo who takes a vessel on charter for a specified period from the owner and then trades the ship to carry cargoes at a profit above the hire rate, or even makes a profit in ...
