Admiralty Three-drum Boiler
Three-drum boilers are a class of water-tube boiler used to generate steam, typically to power Steamship, 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 Glossary of boiler terms#Water drum, water drums, in a triangular layout. Water tubes fill in the two sides of this triangle between the drums, and the Industrial furnace, 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 Glossary of boiler terms#Firedoor, firedoors and teams of Fireman (steam engine), stokers, often from both ends. Development Development of the three-drum boiler began in the late 19th century, with the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flotilla Leader
A flotilla leader was a warship of late 19th century and early 20th century navies suitable for commanding a flotilla of destroyers or other small warships, typically a small cruiser or a large destroyer (known as a destroyer leader). The flotilla leader provided space, equipment and staff for the flotilla commodore (who typically held the rank of captain), including a wireless room, senior engineering and gunnery officers, and administrative staff to support the officers. Originally, older light or scout cruiser A scout cruiser was a type of warship of the early 20th century, which were smaller, faster, more lightly armed and armoured than protected cruisers or light cruisers, but larger than contemporary destroyers. Intended for fleet scouting duties a ...s were often used, but in the early 1900s, the rapidly increasing speed of new destroyer designs meant that such vessels could no longer keep pace with their charges. Accordingly, large destroyer designs were produced for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tobermory, Mull
Tobermory (; ) is the capital of, and until 1973 the only burgh on, the Isle of Mull in the Scottish Inner Hebrides. It is located on the east coast of Mishnish, the most northerly part of the island, near the northern entrance of the Sound of Mull. The town was founded as a fishing port in 1788; its layout was based on the designs of Dumfriesshire engineer Thomas Telford. As of 2022 its population was 1,045. It is notable as the location for the 2002–05 children's programme ''Balamory'' by the BBC. Etymology The name ''Tobermory'' is derived from the Scottish Gaelic, Gaelic ', meaning "Mary's well". The name refers to a well located nearby which was dedicated in ancient times to the Mary, mother of Jesus, Virgin Mary. Prehistory and archaeology Archaeological excavations have taken place at Baliscate just outside of the town. The site was first noted by Hylda Marsh and Beverley Langhorn as part of the Scotland's Rural Past. In 2009, it was partially excavated by ''Time T ...

Commissioned (ship)
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before it is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and Electronics, electronic systems, Galley (kitchen), galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Launched (ship)
Ceremonial ship launching involves the performing of ceremonies associated with the process of transferring a vessel to the water. It is a nautical tradition in many cultures, dating back millennia, 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 the end-on la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laid Down
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 a ship's life; the others are launching, commissioning, and decommissioning. Earlier, 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, although s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Scotland is a Countries of the United Kingdom, country that is part of the United Kingdom. It contains nearly one-third of the United Kingdom's land area, consisting of the northern part of the island of Great Britain and more than 790 adjacent Islands of Scotland, islands, principally in the archipelagos of the Hebrides and the Northern Isles. To the south-east, Scotland has its Anglo-Scottish border, only land border, which is long and shared with England; the country is surrounded by the Atlantic Ocean to the north and west, the North Sea to the north-east and east, and the Irish Sea to the south.

Depth Charge
A depth charge is an anti-submarine warfare (ASW) weapon designed to destroy submarine A submarine (often shortened to sub) is a watercraft capable of independent operation underwater. (It differs from a submersible, which has more limited underwater capability.) The term "submarine" is also sometimes used historically or infor ...s by detonating in the water near the target and subjecting it to a destructive shock factor, hydraulic shock. Most depth charges use high explosives with a fuze set to detonate the charge, typically at a specific depth from the surface. Depth charges can be dropped by ships (typically fast, agile surface combatants such as destroyers or frigates), patrol aircraft and helicopters. Depth charges were developed during World War I, and were one of the first viable methods of attacking a submarine underwater. They were widely used in World War I and World War II, and remained part of the anti-submarine arsenals of many navies during the Cold War, duri ...
