Georgetown, Prince Edward Island
Georgetown is a community located within the municipality of Three Rivers in Kings County, Prince Edward Island, Canada. It is the Capital of Kings County. Previously incorporated as a town, it amalgamated with the town of Montague, the rural municipalities of Brudenell, Cardigan, Lorne Valley, Lower Montague, and Valleyfield, and portions of three adjacent unincorporated areas in 2018. History This area of eastern Prince Edward Island traces its history of human settlement to the Mi'kmaq Nation, which long inhabited the area. These people were referred to as ''Epegoitnag'' and for them, the region was an Acadian forest. It had wild game, as well as fruit, berries and wild nuts for gathering, and plentiful marine resources in the nearby rivers and Northumberland Strait. The land in this area was called ''Samkook'', which translates to 'the land of the sandy shore'. Georgetown lies opposite Brudenell Point, which divides the Brudenell River to the north from the Monta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CFB Halifax
Canadian Forces Base (CFB) Halifax is Canada's east coast naval base and home port to the Royal Canadian Navy Atlantic fleet, known as Canadian Fleet Atlantic (CANFLTLANT), that forms part of the formation Maritime Forces Atlantic (MARLANT). It is the largest Canadian Forces Base in terms of the number of posted personnel and is formed from an amalgamation of military properties situated around the strategic Halifax Harbour in Nova Scotia. Majesty's Canadian Dockyard (HMC Dockyard Halifax) History HMC Dockyard Halifax was acquired by the Canadian government from the Royal Navy following the withdrawal of British military forces from Canada in 1906. Prior to 1906, it was known as Royal Naval Dockyard, Halifax and is one of the oldest defence establishments in Canada, having been established by the Royal Navy during the 18th century as HM Dockyard. While awaiting transfer to Canada, the dockyard fell into disrepair. The dockyard was formally taken over from the British government ...

Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first trans-Atlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code abbreviations to denote the various individual stations on the line (for instance, AX could represent Halifax). "N" and two letters would identify U.S. Navy; "M" and two letters would be a Marconi station. On Apr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glen Class Tug (1975)
The Glen-class tug is a class of naval tugboat operated by the Royal Canadian Navy. Constructed in Canada, the class entered service between 1975 and 1977. The five vessels that comprise the class are split between the two major naval bases of the Royal Canadian Navy. The Royal Canadian Navy operated a fleet of tugboats during the Second World War which were also named the . The vessels of the current Glen class are each named after one of the vessels of the earlier class. Description The Glen class is a series of five yard tractor tugboats designed for coastal/harbour use in Canada's major naval bases. The vessels have a standard displacement of . As built they are long with a beam of and a draught of . They are propelled by two Voith Schneider cycloidal propellers turned by two Ruston-Paxman diesel engines rated at . This gives them a maximum speed of . They initially had a complement of six officers and ratings. Ships The five vessels are divided between the two fleet ...

Tugboat
A tugboat or tug is a marine vessel that manoeuvres other vessels by pushing or pulling them, with direct contact or a tow line. These boats typically tug ships in circumstances where they cannot or should not move under their own power, such as in crowded harbour or narrow canals, or cannot move at all, such as barges, disabled ships, log rafts, or oil platforms. Some are ocean-going, some are icebreakers or salvage tugs. Early models were powered by steam engines, long ago superseded by diesel engines. Many have deluge gun water jets, which help in firefighting, especially in harbours. Types Seagoing Seagoing tugs (deep-sea tugs or ocean tugboats) fall into four basic categories: #The standard seagoing tug with model bow that tows almost exclusively by way of a wire cable. In some rare cases, such as some USN fleet tugs, a synthetic rope hawser may be used for the tow in the belief that the line can be pulled aboard a disabled ship by the crew owing to its lightness ...

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] |
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] |
Voith Schneider Propeller
The Voith Schneider Propeller (VSP) is a specialized marine propulsion system (MPS) manufactured by the Voith Group based on a cyclorotor design. It is highly maneuverable, being able to change the direction of its thrust almost instantaneously. It is widely used on tugs and ferries. Operation From a circular plate, rotating around a vertical axis, a circular array of vertical blades (in the shape of hydrofoils) protrude out of the bottom of the ship. Each blade can rotate itself around a vertical axis. The internal gear changes the angle of attack of the blades in sync with the rotation of the plate, so that each blade can provide thrust in any direction. Unlike the azimuth thruster (where a conventional propeller is rotated about the vertical axis to direct its thrust, allowing a vessel to steer without the use of a rudder), the Voith-Schneider drive merely requires changing the pattern of orientation of the vertical blades. In a marine situation, this provides for a drive ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bollard Pull
Bollard pull is a conventional measure of the pulling (or towing) power of a watercraft. It is defined as the force (in tonnes force, or kilonewtons (kN)) exerted by a vessel under full power, on a shore-mounted bollard through a tow-line, commonly measured in a practical test (but sometimes simulated) under test conditions that include calm water, no tide, level trim, and sufficient depth and side clearance for a free propeller stream. Like the horsepower or mileage rating of a car, it is a convenient but idealized number that must be adjusted for operating conditions that differ from the test. The bollard pull of a vessel may be reported as two numbers, the ''static'' or ''maximum'' bollard pull - the highest force measured - and the ''steady'' or ''continuous'' bollard pull, the average of measurements over an interval of, for example, 10 minutes. An equivalent measurement on land is known as drawbar pull, or tractive force, which is used to measure the total horizontal for ...

Georgetown Shipyard
Saint John Shipbuilding was a Canadian shipbuilding company located in Saint John, New Brunswick. The shipyard was active from 1923 to 2003. History Numerous shipyards were located on the shores of Courtney Bay in the east end of Saint John Harbour where extensive mud flats dried at low tide. In 1918 it was announced that the St. John Drydock & Shipbuilding Co. would be established as a subsidiary of the Canada Dredging Co., Ltd. of Midland, Ontario and would construct the largest drydock in the world. The new shipyard with its massive drydock opened in 1923 at a location on the eastern shore of Courtney Bay.
