Mark 8 Landing Craft Tank
The Mark 8 Landing Craft Tank (also referred to as the LCT (8) or LCT Mark VIII) were landing craft tank ships operated by the British Armed Forces. The vessels were based on an American design, but improved into ocean-going vessels capable of sailing to and operating in the Far East. Although 187 vessels were ordered, the end of the Second World War meant that only 30 were completed for service in the Royal Navy, while another 6 were sold to civilian parties. Twelve of the Royal Navy vessels were, from 1957, transferred to the British Army; these were initially operated by the Royal Army Service Corps, which then became the Royal Corps of Transport. Between 1958 and 1966, the other 18 Royal Navy ships were transferred or sold to foreign navies or civilian companies, converted for other uses, or otherwise disposed of. Several Army Mark 8s were also sold to foreign powers, with the design operated by the Royal Malaysian Navy, the French Navy, the Singaporean Navy, and the Military ...

St Kilda, Scotland
St Kilda ( gd, Hiort) is an isolated archipelago situated west-northwest of North Uist in the North Atlantic Ocean. It contains the westernmost islands of the Outer Hebrides of Scotland. The largest island is Hirta, whose sea cliffs are the highest in the United Kingdom; three other islands ( Dùn, Soay and Boreray) were also used for grazing and seabird hunting. The islands are administratively a part of the Comhairle nan Eilean Siar local authority area. The origin of the name ''St Kilda'' is a matter of conjecture. The islands' human heritage includes numerous unique architectural features from the historic and prehistoric periods, although the earliest written records of island life date from the Late Middle Ages. The medieval village on Hirta was rebuilt in the 19th century, but illnesses brought by increased external contacts through tourism, and the upheaval of the First World War contributed to the island's evacuation in 1930. The story of St Kilda has attracted artis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hebrides
The Hebrides (; gd, Innse Gall, ; non, Suðreyjar, "southern isles") are an archipelago off the west coast of the Scottish mainland. The islands fall into two main groups, based on their proximity to the mainland: the Inner and Outer Hebrides. These islands have a long history of occupation (dating back to the Mesolithic period), and the culture of the inhabitants has been successively influenced by the cultures of Celtic-speaking, Norse-speaking, and English-speaking peoples. This diversity is reflected in the various names given to the islands, which are derived from the different languages that have been spoken there at various points in their history. The Hebrides are where much of Scottish Gaelic literature and Gaelic music has historically originated. Today, the economy of the islands is dependent on crofting, fishing, tourism, the oil industry, and renewable energy. The Hebrides have less biodiversity than mainland Scotland, but a significant number of seals an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine (gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is une ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paxman (engines)
Paxman is a major British brand of diesel engines. Ownership has changed on a number of occasions since the company's formation in 1865, and now the brand is part of MAN Diesel & Turbo. At its peak, the Paxman works covered and employed over 2,000 people. Early Paxman diesel engines (with "Comet" indirect injection cylinder heads, designed by Sir Harry Ricardo) carried the name Paxman Ricardo. History Davey Paxman Paxman was founded by James Noah Paxman, Henry and Charles Davey as Davey, Paxman & Davey, Engineers in 1865, later Davey, Paxman & Co. which became a limited company in 1898. In 1920 the company became a member of the Agricultural & General Engineers (AGE) combine. In 1932 AGE collapsed and Paxman emerged as Davey Paxman & Co (Colchester) Ltd. Davey, Paxman and Davey conducted business as general engineers and ironworkers. The company manufactured steam engines, boilers, agricultural machinery, and mill gearing. By the early 1870s the company was supplying mach ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

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.

Landing Ship, Tank
Landing Ship, Tank (LST), or tank landing ship, is the naval designation for ships first developed during World War II (1939–1945) to support amphibious operations by carrying tanks, vehicles, cargo, and landing troops directly onto shore with no docks or piers. This enabled amphibious assaults on almost any beach. The LST had a highly specialized design that enabled ocean crossings as well as shore groundings. The bow had a large door that could open, deploy a ramp and unload vehicles. The LST had a flat keel that allowed the ship to be beached and stay upright. The twin propellers and rudders had protection from grounding. The LSTs served across the globe during World War II including in the Pacific War and in the European theatre. The first tank-landing ships were built to British requirements by converting existing ships; the UK and the US then collaborated upon a joint design. The British ships were used in late 1942 during the Allied invasion of Algeria, by 1943 LST ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Landing Craft Tank
The Landing Craft, Tank (LCT) (or Tank Landing Craft TLC) was an amphibious assault craft for landing tanks on beachheads. They were initially developed by the Royal Navy and later by the United States Navy during World War II in a series of versions. Initially known as the "tank landing craft" (TLC) by the British, they later adopted the U.S. nomenclature "landing craft, tank" (LCT). The United States continued to build LCTs post-war, and used them under different designations in the Korean and Vietnam Wars. Development In 1926, the first motor landing craft (MLC1) was built by the Royal Navy. It weighed 16 tons, with a draught of , and was capable of about . It was later developed into the landing craft mechanised. It was at the insistence of the British prime minister Winston Churchill in mid-1940 that the LCT was created. Its speed was on engines delivering about . Designated the LCT Mark 1, 20 were ordered in July 1940 and a further 10 in October 1940.) Mark 1 The firs ...

Landing Ship Medium
Landing Ship Medium (LSM) were amphibious assault ships of the United States Navy in World War II. Of a size between that of Landing Ships Tank (LST) and Landing Craft Infantry (LCI), 558 LSMs were built for the USN between 1944 and 1945. The majority of vessels built on this frame were regular transports, while several dozen were converted during construction to specialized roles. Most LSMs were scrapped during the Cold War, but several were sold by the United States Department of Defense to foreign nations or private shipping companies. ''LSM-1''-class Landing Ship Medium (Transport) List of ''LSM-1''-class ships In total 558 LSM ships were launched.

Seakeeping
Seakeeping ability or seaworthiness is a measure of how well-suited a watercraft is to conditions when underway. A ship or boat which has good seakeeping ability is said to be very seaworthy and is able to operate effectively even in high sea states. Measure In 1976, St. Denis suggested four principal terms needed to describe a seakeeping performance. These are: *Mission: what the ship is intended to accomplish. The role of the ship while at sea. *Environment: the conditions under which the ship is operating. This can be described as sea state, wind speed, geographic region or some combination thereof. *Ship responses: the response of the ship to the environmental conditions. The responses are a function of the environment and the vessel characteristics. *Seakeeping performance criteria: the established limits for the ship's responses. These are based on the ship motions and the accelerations experienced, and include comfort criteria such as noise, vibration and sea sickness, perfo ...
