HMS Bruizer (1895)
HMS ''Bruizer'' was an which served with the Royal Navy. She was launched on 27 February 1895 by John Thornycroft at Chiswick, and was sold on 26 May 1914. Construction and design On 12 October 1893, the British Admiralty placed an order for three torpedo boat destroyers (, and ''Bruizer'') with the shipbuilder Thornycroft under the 1893–1894 shipbuilding programme for the Royal Navy as a follow-on to the two prototype destroyers ( and ) ordered from Thornycroft under the 1892–1893 programme. The Admiralty did not specify a standard design for destroyers, laying down broad requirements, including a trial speed of , a "turtleback" forecastle and armament, which was to vary depending on whether the ship was to be used in the torpedo boat or gunboat role. As a torpedo boat, the planned armament was a single QF 12 pounder 12 cwt ( calibre) gun on a platform on the ship's conning tower (in practice the platform was also used as the ship's bridge), together with a secon ...

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 ...

Valletta
Valletta (, mt, il-Belt Valletta, ) is an Local councils of Malta, administrative unit and capital city, capital of Malta. Located on the Malta (island), main island, between Marsamxett Harbour to the west and the Grand Harbour to the east, its population within administrative limits in 2014 was 6,444. According to the data from 2020 by Eurostat, the Functional Urban Area and metropolitan region covered the whole island and has a population of 480,134. Valletta is the southernmost capital of Europe, and at just , it is the European Union's smallest capital city. Valletta's 16th-century buildings were constructed by the Hospitaller Malta, Knights Hospitaller. The city was named after Jean Parisot de Valette, who succeeded in defending the island from an Ottoman invasion during the Great Siege of Malta. The city is Baroque architecture, Baroque in character, with elements of Mannerist architecture#Mannerist architecture, Mannerist, Neoclassical architecture, Neo-Classical and Mo ...

Grand Harbour
The Grand Harbour ( mt, il-Port il-Kbir; it, Porto Grande), also known as the Port of Valletta, is a natural harbour on the island of Malta. It has been substantially modified over the years with extensive docks (Malta Dockyard), wharves, and fortifications. Description The harbour mouth faces north east and is bounded to the north by Saint Elmo Point and further sheltered by an isolated breakwater and is bounded to the south by Ricasoli Point. Its north west shore is formed by the Sciberras peninsula, which is largely covered by the city of Valletta and its suburb Floriana. This peninsula also divides Grand Harbour from a second parallel natural harbour, Marsamxett Harbour. The main waterway of Grand Harbour continues inland almost to Marsa. The southeastern shore of the harbour is formed by a number of inlets and headlands, principally Rinella Creek, Kalkara Creek, Dockyard Creek, and French Creek, which are covered by Kalkara and the Three Cities: Cospicua, Vittoriosa, ...

Mediterranean Fleet
The British Mediterranean Fleet, also known as the Mediterranean Station, was a formation of the Royal Navy. The Fleet was one of the most prestigious commands in the navy for the majority of its history, defending the vital sea link between the United Kingdom and the majority of the British Empire in the Eastern Hemisphere. The first Commander-in-Chief for the Mediterranean Fleet was the appointment of General at Sea Robert Blake in September 1654 (styled as Commander of the Mediterranean Fleet). The Fleet was in existence until 1967. Pre-Second World War The Royal Navy gained a foothold in the Mediterranean Sea when Gibraltar was captured by the British in 1704 during the War of Spanish Succession, and formally allocated to Britain in the 1713 Treaty of Utrecht. Though the British had maintained a naval presence in the Mediterranean before, the capture of Gibraltar allowed the British to establish their first naval base there. The British also used Port Mahon, on the isla ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Trials
A sea trial is the testing phase of a watercraft (including boats, ships, and submarines). It is also referred to as a "shakedown cruise" by many naval personnel. It is usually the last phase of construction and takes place on open water, and it can last from a few hours to many days. Sea trials are conducted to measure a vessel's performance and general seaworthiness. Testing of a vessel's speed, maneuverability, equipment and safety features are usually conducted. Usually in attendance are technical representatives from the builder (and from builders of major systems), governing and certification officials, and representatives of the owners. Successful sea trials subsequently lead to a vessel's certification for commissioning and acceptance by its owner. Although sea trials are commonly thought to be conducted only on new-built vessels (referred by shipbuilders as 'builders trials'), they are regularly conducted on commissioned vessels as well. In new vessels, they are used t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ceremonial Ship 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 ...

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] |
Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Three-drum Boiler
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power ships. They are compact and of high evaporative power, factors that encourage this use. Other boiler designs may be more efficient, although bulkier, and so the three-drum pattern was rare as a land-based stationary boiler. The fundamental characteristic of the "three-drum" design is the arrangement of a steam drum above two water drums, in a triangular layout. Water tubes fill in the two sides of this triangle between the drums, and the furnace is in the centre. The whole assembly is then enclosed in a casing, leading to the exhaust flue. Firing can be by either coal or oil. Many coal-fired boilers used multiple firedoors and teams of stokers, often from both ends. Development Development of the three-drum boiler began in the late 19th century, with the demand from naval ships that required high power and a compact boiler. The move to water-tube boilers had already begun, with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p.5. This is accomplished by means of its "draft marks" (or "load lines"). A mer ...
