SS Papoose
''Silvanus'' was a steam tanker built in 1920–1921 by the Southwestern Shipbuilding & Drydock Company of San Pedro for the Anglo-Saxon Petroleum Company with the intention of transporting oil and petroleum products between Dutch East Indies and various destinations in Europe and the Far East. The tanker was employed in this capacity through the first part of 1926. In April 1926 ''Silvanus'' collided with the tanker in the Mississippi River, resulting in the explosion and death of 26 seamen. ''Silvanus'' was declared a total loss and sold at auction to the newly formed Petroleum Navigation Company of Texas. The tanker was rebuilt and renamed ''Papoose'' and started operating in March 1927. In March 1942, she was attacked by German U-boat off the coast of North Carolina. The ship drifted for several days and eventually sank in of water off Oregon Inlet.

Southwestern Shipbuilding & Drydock Company
Bethlehem Shipbuilding San Pedro was a major shipbuilding company on Terminal Island in San Pedro, California owned by Bethlehem Shipbuilding Corporation. To support the World War 2 demand for ships Bethlehem Shipbuilding San Pedro built: US Navy Destroyers and after the war tugboats. The yard became involved in World War II production in the early shipbuilding expansions initiated by the Two-Ocean Navy Act of July 1940. At its peak during the war about 6,000 worked at the yard, Bethlehem Shipbuilding San Pedro shipyard was opened in 1918 as Southwestern Shipbuilding by Western Pipe & Steel. Western Pipe & Steel sold the shipyard to Bethlehem Shipbuilding Corporation in 1925. Shipbuilding ended after World War 2 in 1946. In 1983 the shipyard was sold to Southwest Marine. In 1997 Southwest Marine operated four shipyards, which they sold to The Carlyle Group. Carlyle Group renamed the shipyard US Marine Repair. In 2002 US Marine Repair sold all six of its yards to United Defense ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Carolina
North Carolina () is a state in the Southeastern region of the United States. The state is the 28th largest and 9th-most populous of the United States. It is bordered by Virginia to the north, the Atlantic Ocean to the east, Georgia and South Carolina to the south, and Tennessee to the west. In the 2020 census, the state had a population of 10,439,388. Raleigh is the state's capital and Charlotte is its largest city.

Nominal Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the steam ...

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft ...

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 Hull may refer to: Structures * Chassis, of an armored fighting vehicle * Fuselage, of an aircraft * Hull (botany), the outer covering of seeds * Hull (watercraft), the body or frame of a ship * Submarine hull Mathematics * Affine hull, in affi ..., 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 fro ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured paral ...

Three-island Principle
The three-island principle was a technique used in the construction of steel-hulled ships whereby a ship was built with a forecastle, bridge deck, and poop. The technique allowed the economical and efficient construction of ships and was particularly common in tramp steamers and smaller vessels of the nineteenth and early twentieth centuries. The ''Knight of Malta'', for instance, a 1929 steam ferry of only 16 ft draught that operated between Malta and Sicily, was built on the principle. See also *Deck (ship) A deck is a permanent covering over a compartment or a hull of a ship. On a boat or ship, the primary or upper deck is the horizontal structure that forms the "roof" of the hull, strengthening it and serving as the primary working surface. ...

Longitudinal Framing
Longitudinal framing (also called the Isherwood system after British naval architect Sir Joseph Isherwood, who patented it in 1906) is a method of ship construction in which large, widely spaced transverse frames are used in conjunction with light, closely spaced longitudinal members. This method, Isherwood felt, lent a ship much greater longitudinal strength than in ships built in the traditional method, where a series of closely spaced transverse frames are fitted from the keel to the sheer line, with corresponding deck beams, a method that is well suited to support longitudinal planking. Longitudinal framing was a known method of shipbuilding before Isherwood. Naval engineer J. Scott Russell, for instance, had built several longitudinally framed ships, including the SS ''Great Eastern''. However, no one had made the process practical from a commercial standpoint, which was Isherwood's achievement. The first commercial vessel constructed with the Isherwood system, the oil- ...

Joseph Isherwood
Sir Joseph William Isherwood, 1st Baronet (23 June 1870 – 24 October 1937) was a British naval architect. He invented the Isherwood System of longitudinal construction of ships and the Arcform System. Isherwood was born in Hartlepool, the son of a grocer. He was educated at Luggs School on the Headland, near St Hilda's church, and at the age of fifteen entered the drawing office of the Hartlepool shipbuilders Edward Withy & Co. He served in several departments in that firm and in 1896 left to become a ship surveyor with Lloyd's Register of Shipping. Here he developed the Isherwood System, a new stronger, safer, and cheaper longitudinal girder form of ship construction designed to replace the traditional traverse construction method (ribs placed at regular intervals along the keel), which he patented in 1906. In 1907 he left Lloyd's to join the board of the shipbuilders R. Craggs & Sons of Middlesbrough, but soon returned to London to practise as a naval architect. Th ...

Keel
The keel is the bottom-most longitudinal structural element on a vessel. On some sailboats, it may have a hydrodynamic and counterbalancing purpose, as well. As the laying down of the keel is the initial step in the construction of a ship, in British and American shipbuilding traditions the construction is dated from this event. Etymology The word "keel" comes from Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work '' De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careen (to clean a keel and the hull in general, often by rolling the ship on its side). An example of this use is Careening Cove, a suburb of Sydney, Australia, where careening was carried o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Newspapers
A newspaper is a periodical publication containing written information about current events and is often typed in black ink with a white or gray background. Newspapers can cover a wide variety of fields such as politics, business, sports and art, and often include materials such as opinion columns, weather forecasts, reviews of local services, obituaries, birth notices, crosswords, editorial cartoons, comic strips, and advice columns. Most newspapers are businesses, and they pay their expenses with a mixture of subscription revenue, newsstand sales, and advertising revenue. The journalism organizations that publish newspapers are themselves often metonymically called newspapers. Newspapers have traditionally been published in print (usually on cheap, low-grade paper called newsprint). However, today most newspapers are also published on websites as online newspapers, and some have even abandoned their print versions entirely. Newspapers developed in the 17th ...
