SS Ben-my-Chree (1908)
TSS (RMS) ''Ben-my-Chree'' (III) No. 118605 – the third vessel in the company's history to be so named – was a passenger steamer operated by the Isle of Man Steam Packet Company between 1908 and 1915. ''Ben-my-Chree'' was requisitioned by the Admiralty in 1915 and converted to a seaplane carrier; commissioned as ''HMS Ben-my-Chree'', she was sunk by Turkish batteries on 11 January 1917. ''Ben-my-Chree'' was built in 1908 at the Vickers Sons and Maxim shipyard, Barrow in Furness. She was the fifth ship built in the Barrow yard for the Isle of Man Steam Packet, and was launched by Mrs. J. T. Cowell at 13:45hrs on Monday 23 March 1908.''The Isle of Man Times.'' Saturday, 28 March 1908 ''Ben-my-Chree'' is regarded as amongst the finest and certainly the fastest of vessels ever to serve the line. In appearance she was said to resemble a mini Cunarder rather than a conventional cross-channel steamer, proudly being described by the Company as: ''"the fastest and most luxurious ...

RMS Mauretania (1906)
RMS ''Mauretania'' was an ocean liner designed by Leonard Peskett and built by Wigham Richardson and Swan Hunter for the British Cunard Line, launched on the afternoon of 20 September 1906. She was the world's largest ship until the launch of in 1910. ''Mauretania'' became a favourite among her passengers. She captured the eastbound Blue Riband on her maiden return voyage in December 1907, then claimed the westbound Blue Riband for the fastest transatlantic crossing during her 1909 season, which she held both speed records for 20 years.Maxtone-Graham 1972, pp. 41–43. The ship's name was taken from the ancient Roman province of Mauretania on the northwest African coast, not the modern Mauritania to the south.Maxtone-Graham 1972, p. 24. Similar nomenclature was also employed by ''Mauretania''s running mate , which was named after the Roman province directly north of Mauretania, across the Strait of Gibraltar in Portugal. ''Mauretania'' remained in service until September 1934, ... [...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-fuels, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slipway
A slipway, also known as boat ramp or launch or boat deployer, is a ramp on the shore by which ships or boats can be moved to and from the water. They are used for building and repairing ships and boats, and for launching and retrieving small boats on trailers towed by automobiles and flying boats on their undercarriage. The nautical terms ways and skids are alternative names for slipway. A ship undergoing construction in a shipyard is said to be ''on the ways''. If a ship is scrapped there, she is said to be ''broken up in the ways''. As the word "slip" implies, the ships or boats are moved over the ramp, by way of crane or fork lift. Prior to the move the vessel's hull is coated with grease, which then allows the ship or boat to "slip" off of the ramp and progress safely into the water. Slipways are used to launch (newly built) large ships, but can only dry-dock or repair smaller ships. Pulling large ships against the greased ramp would require too much force. Therefor ...

Thermal Efficiency
In thermodynamics, the thermal efficiency (\eta_) is a dimensionless performance measure of a device that uses thermal energy, such as an internal combustion engine, steam turbine, steam engine, boiler, furnace, refrigerator, ACs etc. For a heat engine, thermal efficiency is the ratio of the net work output to the heat input; in the case of a heat pump, thermal efficiency (known as the ''coefficient of performance'') is the ratio of net heat output (for heating), or the net heat removed (for cooling) to the energy input (external work). The efficiency of a heat engine is fractional as the output is always less than the input while the COP of a heat pump is more than 1. These values are further restricted by the Carnot theorem. Overview In general, energy conversion efficiency is the ratio between the useful output of a device and the input, in energy terms. For thermal efficiency, the input, Q_, to the device is heat, or the heat-content of a fuel that is consumed. The des ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RMS Lady Of Mann
TSS (RMS) ''Lady of Mann'' ( No. 145307), was a passenger ship, built by Vickers Shipbuilding and Engineering for the Isle of Man Steam Packet Company at Barrow-in-Furness in 1930, at a cost of £249,073. Certificated to carry 2,873 passengers and 81 crew, she was commissioned to operate on the Island's busy Douglas–Liverpool and Douglas–Fleetwood routes, and had a maximum speed of 23 knots. Her hull was at first the company's conventional black, but was changed to white and green in 1933,Ships of the Isle of Man Steam Packet Company: Fred Henry 1962 page 50. only to revert to black after her war service. Service life The year 1930 saw the Isle of Man Steam Packet Company celebrate its centenary, and to mark this, ''Lady of Mann'' was to be the largest ship ever built for it to that date.Ships of the Isle of Man Steam Packet Company: Fred Henry 1962 page 27. The keel of ''Lady of Mann'' was laid on 26 October 1929, and by early spring the following year she was ready for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 para ...

Tonnage
Tonnage is a measure of the cargo-carrying capacity of a ship, and is commonly used to assess fees on commercial shipping. The term derives from the taxation paid on ''tuns'' or casks of wine. In modern maritime usage, "tonnage" specifically refers to a calculation of the volume or cargo volume of a ship. Although tonnage (volume) should not be confused with displacement (the actual weight of the vessel), the long ton (or imperial ton) of 2,240 lb is derived from the fact that a "tun" of wine typically weighed that much. Tonnage measurements Tonnage measurements are governed by an IMO Convention (International Convention on Tonnage Measurement of Ships, 1969 (London-Rules)), which initially applied to all ships built after July 1982, and to older ships from July 1994.

Board Of Trade
The Board of Trade is a British government body concerned with commerce and industry, currently within the Department for International Trade. Its full title is The Lords of the Committee of the Privy Council appointed for the consideration of all matters relating to Trade and Foreign Plantations, but is commonly known as the Board of Trade, and formerly known as the Lords of Trade and Plantations or Lords of Trade, and it has been a committee of the Privy Council of the United Kingdom. The board has gone through several evolutions, beginning with extensive involvement in colonial matters in the 17th century, to powerful regulatory functions in the Victorian Era and early 20th century. It was virtually dormant in the last third of 20th century. In 2017, it was revitalised as an advisory board headed by the International Trade Secretary who has nominally held the title of President of the Board of Trade, and who at present is the only privy counsellor of the board, the other m ...

Lloyd's Of London
Lloyd's of London, generally known simply as Lloyd's, is an insurance and reinsurance market located in London, England. Unlike most of its competitors in the industry, it is not an insurance company; rather, Lloyd's is a corporate body governed by the Lloyd's Act 1871 and subsequent Acts of Parliament. It operates as a partially-mutualised marketplace within which multiple financial backers, grouped in syndicates, come together to pool and spread risk. These underwriters, or "members", are a collection of both corporations and private individuals, the latter being traditionally known as "Names". The business underwritten at Lloyd's is predominantly general insurance and reinsurance, although a small number of syndicates write term life insurance. The market has its roots in marine insurance and was founded by Edward Lloyd at his coffee house on Tower Street in 1688. Today, it has a dedicated building on Lime Street which is Grade I listed. Traditionally business is tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liverpool
Liverpool is a city and metropolitan borough in Merseyside, England. With a population of in 2019, it is the 10th largest English district by population and its metropolitan area is the fifth largest in the United Kingdom, with a population of 2.24 million. On the eastern side of the Mersey Estuary, Liverpool historically lay within the ancient hundred of West Derby in the county of Lancashire. It became a borough in 1207, a city in 1880, and a county borough independent of the newly-created Lancashire County Council in 1889. Its growth as a major port was paralleled by the expansion of the city throughout the Industrial Revolution. Along with general cargo, freight, and raw materials such as coal and cotton, merchants were involved in the slave trade. In the 19th century, Liverpool was a major port of departure for English and Irish emigrants to North America. It was also home to both the Cunard and White Star Lines, and was the port of registry of the ocean li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
