Lobnitz
Lobnitz & Company was a Scottish shipbuilding company located at Renfrew on the River Clyde, west of the Renfrew Ferry crossing and east of the confluence with the River Cart. The Lobnitz family lived at Chapeltoun House in East Ayrshire. The company built dredgers, floating docks, fishing boats, tugs and workboats. History The company was descended from Coulburn Lobnitz & Company, established in 1874, and the adjacent shipyard of William Simons & Co, established in 1860. Both builders specialised in the construction of dredgers and hopper barges. The two companies amalgamated in 1957 as Simons-Lobnitz Ltd. Faced with declining business the Renfrew yard finally closed in 1964 after some 1300 dredgers as well as barges and tugs had been built at the site. One late example survives: SS ''Shieldhall'' was built as a Clyde sludge boat in 1954 with reciprocating steam engines, and now operates as a pleasure cruiser on the Solent. Also still afloat is the ''William C. Daldy' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fuel Oil
Fuel oil is any of various fractions obtained from the distillation of petroleum (crude oil). Such oils include distillates (the lighter fractions) and residues (the heavier fractions). Fuel oils include heavy fuel oil, marine fuel oil (MFO), bunker fuel, furnace oil (FO), gas oil (gasoil), heating oils (such as home heating oil), diesel fuel and others. The term ''fuel oil'' generally includes any liquid fuel that is burned in a furnace or boiler to generate heat ( heating oils), or used in an engine to generate power (as motor fuels). However, it does not usually include other liquid oils, such as those with a flash point of approximately , or oils burned in cotton- or wool-wick burners. In a stricter sense, ''fuel oil'' refers only to the heaviest commercial fuels that crude oil can yield, that is, those fuels heavier than gasoline (petrol) and naphtha. Fuel oil consists of long-chain hydrocarbons, particularly alkanes, cycloalkanes, and aromatics. Small molecules, such as t ...

Convoy
A convoy is a group of vehicles, typically motor vehicles or ships, traveling together for mutual support and protection. Often, a convoy is organized with armed defensive support and can help maintain cohesion within a unit. It may also be used in a non-military sense, for example when driving through remote areas. Naval convoys Age of Sail Naval convoys have been in use for centuries, with examples of merchant ships traveling under naval protection dating to the 12th century. The use of organized naval convoys dates from when ships began to be separated into specialist classes and national navies were established. By the French Revolutionary Wars of the late 18th century, effective naval convoy tactics had been developed to ward off pirates and privateers. Some convoys contained several hundred merchant ships. The most enduring system of convoys were the Spanish treasure fleets, that sailed from the 1520s until 1790. When merchant ships sailed independently, a privateer cou ...

Arctic
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...

North Sea
The North Sea lies between Great Britain, Norway, Denmark, Germany, the Netherlands and Belgium. An epeiric sea on the European continental shelf, it connects to the Atlantic Ocean through the English Channel in the south and the Norwegian Sea in the north. It is more than long and wide, covering . It hosts key north European shipping lanes and is a major fishery. The coast is a popular destination for recreation and tourism in bordering countries, and a rich source of energy resources, including wind and wave power. The North Sea has featured prominently in geopolitical and military affairs, particularly in Northern Europe, from the Middle Ages to the modern era. It was also important globally through the power northern Europeans projected worldwide during much of the Middle Ages and into the modern era. The North Sea was the centre of the Vikings' rise. The Hanseatic League, the Dutch Republic, and the British each sought to gain command of the North Sea and access t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nore
The Nore is a long bank of sand and silt running along the south-centre of the final narrowing of the Thames Estuary, England. Its south-west is the very narrow Nore Sand. Just short of the Nore's easternmost point where it fades into the channels it has a notable point once marked by a lightship on the line where the estuary of the Thames nominally becomes the North Sea. A lit buoy today stands on this often map-marked divisor: between Havengore Creek in east Essex and Warden Point on the Isle of Sheppey in Kent. Until 1964 it marked the seaward limit of the Port of London Authority. As the sandbank was a major hazard for shipping coming in and out of London, in 1732 it received the world's first lightship. This became a major landmark, and was used as an assembly point for shipping. Today it is marked by Sea Reach No. 1 Buoy. The Nore is an anchorage, or open roadstead, used by the Royal Navy's North Sea Fleet, and to its local Command. It was the site of a notorious mu ...

Flotilla
A flotilla (from Spanish, meaning a small ''flota'' (fleet) of ships), or naval flotilla, is a formation of small warships that may be part of a larger fleet. Composition A flotilla is usually composed of a homogeneous group of the same class of warship, such as frigates, destroyers, torpedo boats, submarines, gunboats, or minesweepers. Groups of larger warships are usually called squadrons, but similar units of non-capital ships may be called squadrons in some instances, and flotillas in others. Formations including more than one capital ship, e.g. men-of-war, battleships, and aircraft carriers, typically alongside smaller ships and support craft, are typically called fleets, each portion led by a capital ship being a squadron or task force (see reference below). A flotilla is usually commanded by a rear admiral, a commodore or a captain, depending on the importance of the command (a vice admiral would normally command a squadron). A flotilla is often divided into two or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Urban District (England And Wales)
In England and Wales an urban district was a type of local government district that covered an urbanised area. Urban districts had an elected urban district council (UDC), which shared local government responsibilities with a county council. In England and Wales, urban districts and rural districts were created in 1894 (by the Local Government Act 1894) as subdivisions of administrative counties. A similar model of urban and rural districts was also established in Ireland in 1899, which continued separately in Northern Ireland and the Republic of Ireland after 1921. They replaced the earlier system of urban and rural sanitary districts (based on poor law unions) whose functions were taken over by the district councils. The district councils also had wider powers over local matters such as parks, cemeteries and local planning. An urban district usually contained a single parish, while a rural district might contain many. Urban districts were considered to have more problems wi ...

Warship Week
Warship Weeks were British National savings campaigns during the Second World War, with the aim of a Royal Navy warship being adopted by a civil community. During the early parts of the war, the Royal Navy not only had lost many capital ships but was facing increasing pressure to provide escorts for convoys in the Atlantic. While there was not a shortage of sailors, ships sunk by enemy action had to be replaced. The equivalent for the British Army was Salute the Soldier Week and the equivalent for the Royal Air Force was Wings for Victory Week. Campaign Local fund-raising A level of savings would be set to raise enough money to provide the cost of building a particular naval ship. The aim was for cities to raise enough to adopt battleships and aircraft carriers, while towns and villages would focus on cruisers and destroyers. Smaller towns and villages would be set a lower figure. Once the target money was saved for the ship, the community would adopt the ship and its crew. ...
