SS Walnut
SS ''Walnut'' was a refugee ship converted from a British minesweeping Tree-class trawler which carried Baltic refugees from Sweden to Canada in 1948. The refugees' arrival at Pier 21 in Halifax, Nova Scotia led to a controversy which played an important role in shaping Canada's postwar refugee policies. Initially entering service during the Second World War as HMS ''Walnut'', the trawler was sold for commercial purposes following the war. Converted for use as a cargo ship, the vessel retained the name ''Walnut'' until 1959 when sold and renamed ''Keta''. The ship was Ship breaking, broken up in 1976. Design and description Tree-class trawlers were designed to Displacement (ship), displace 545 tons standard and 770 tons at deep load. They were Length overall, long overall with a Beam (nautical), beam of and a Draft (hull), draught of . They were powered by a one-cylinder boiler providing steam to one triple expansion engine, vertical triple expansion engine. This drove one sha ...

Smiths Dock Company
Smith's Dock Company, Limited, often referred to simply as Smith's Dock, was a British shipbuilding company. History The company was originally established by Thomas Smith who bought William Rowe's shipyard at St. Peter's in Newcastle upon Tyne in 1810 and traded as William Smith & Co. The company opened its dock in North Shields in 1851. One of the first ships to be launched at the yard was ''Termagent'' in 1852. The company changed its name to Smith's Dock Co. in 1891. The company became associated with South Bank, North Riding of Yorkshire, after opening an operation there in 1907. Smith's Dock increasingly concentrated its shipbuilding business on the River Tees in South Bank, with its North Shields Yard being used mainly for repair work (in particular oil tankers) from 1909 onwards. Despite the shift of focus, The company's headquarters remained at North Shields. Smith's Dock built many ships that served during the Second World War, including trawlers that the Admiralty re ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about the use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 ocean ships were broken down, and their average age was ...

Distinguished Service Cross (United Kingdom)
The Distinguished Service Cross (DSC) is a third-level military decoration awarded to officers; and, since 1993, Naval rating, ratings and other ranks of the British Armed Forces, Royal Fleet Auxiliary and the British Merchant Navy have been included. Additionally, the award was formerly awarded to members of other Commonwealth of Nations, Commonwealth countries. The DSC is "awarded in recognition of an act or acts of exemplary gallantry during active operations against the enemy at sea." Since 1979, it can be awarded posthumously. History The award was originally created in 1901 as the Conspicuous Service Cross, for award to warrant officer, warrant and subordinate officers, including midshipman, midshipmen, ineligible for the Distinguished Service Order. It was renamed the Distinguished Service Cross in October 1914, eligibility being extended to all naval officers (commissioned and warrant) below the rank of lieutenant commander.Abbott & Tamplin, pages 107-109.

Ship Naming And Launching
Ceremonial ship launching involves the performance of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back thousands of years, to accompany the physical process with ceremonies which have been observed as public celebration and a solemn blessing, usually but not always, in association with the launch itself. Ship launching imposes stresses on the ship not met during normal operation and, in addition to the size and weight of the vessel, represents a considerable engineering challenge as well as a public spectacle. The process also involves many traditions intended to invite good luck, such as christening by breaking a sacrificial bottle of champagne over the bow as the ship is named aloud and launched. Methods There are three principal methods of conveying a new ship from building site to water, only two of which are called "launching". The oldest, most familiar, and most widely used is th ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 life ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
20 Mm Oerlikon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seebac ...

Triple Expansion Engine
A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed, by a connecting rod and crank, into rotational force for work. The term "steam engine" is generally applied only to reciprocating engines as just described, not to the steam turbine. Steam engines are external combustion engines, where the working fluid is separated from the combustion products. The ideal thermodynamic cycle used to analyze this process is called the Rankine cycle. In general usage, the term ''steam engine'' can refer to either complete steam plants (including boilers etc.), such as railway steam locomotives and portable engines, or may refer to the piston or turbine machinery alone, as in the beam engine and stationary steam engine. Although steam-driven devices were known as early as the aeolipile ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
