Queen Of Oak Bay
MV ''Queen of Oak Bay'' is a double-ended roll-on/roll-off ferry in the BC Ferries fleet, launched in 1981 at Victoria, British Columbia. The long, 6,969-ton vessel has a capacity for 362 cars and over 1,500 passengers and crew. She normally operates on BC Ferries' Horseshoe Bay to Departure Bay (Nanaimo) route, part of the Trans-Canada Highway. She is named for the district of Oak Bay. Mid-life upgrade The vessel underwent a $35 million mid-life upgrade in early 2005 at Vancouver Drydock Company in North Vancouver. The project prepared the vessel for another 20 years of service with upgrades to engineering components, lifesaving equipment and improvements to onboard services. Major maintenance work included steel replacement, piping and cable renewal, hull sandblasting and extensive painting. The vessel was outfitted with four state-of-the art marine evacuation systems, supplemented by two rescue boats and eight life rafts. She returned to service on June 13, 2005. 2005 ...

BC Ferries
British Columbia Ferry Services Inc., operating as BC Ferries (BCF), is a former provincial Crown corporation, now operating as an independently managed, publicly owned Canadian company. BC Ferries provides all major passenger and vehicle ferry services for coastal and island communities in the Canadian province of British Columbia. Set up in 1960 to provide a similar service to that provided by the Black Ball Line and the Canadian Pacific Railway, which were affected by job action at the time, BC Ferries has become the largest passenger ferry line in North America, operating a fleet of 36 vessels with a total passenger and crew capacity of over 27,000, serving 47 locations on the B.C. coast. The federal and provincial governments subsidize BC Ferries to provide agreed service levels on essential links between the BC mainland, coastal islands, and parts of the mainland without road access. The inland ferries operating on British Columbia's rivers and lakes are not run by BC Fer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Grounding
Ship grounding or ship stranding is the impact of a ship on seabed or waterway side. It may be intentional, as in beaching to land crew or cargo, and careening, for maintenance or repair, or unintentional, as in a marine accident. In accidental cases, it is commonly referred to as "running aground". When unintentional, grounding may result simply in stranding, with or without damage to the submerged part of the ship's hull. Breach of the hull may lead to significant flooding, which in the absence of containment in watertight bulkheads may substantially compromise the ship's structural integrity, stability, and safety. As hazard Severe grounding applies extreme loads upon ship structures. In less severe accidents, it might result only in damage to the hull; however, in most serious accidents, it might lead to hull breaches, cargo spills, total loss of the vessel, and, in the worst cases, human casualties. Grounding accounts for about one-third of commercial ship accidents,Kit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Trial
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Propulsion
Marine propulsion is the mechanism or system used to generate thrust to move a watercraft through water. While paddles and sails are still used on some smaller boats, most modern ships are propelled by mechanical systems consisting of an electric motor or internal combustion engine driving a propeller, or less frequently, in pump-jets, an impeller. Marine engineering is the discipline concerned with the engineering design process of marine propulsion systems. Human-powered paddles and oars, and later, sails were the first forms of marine propulsion. Rowed galleys, some equipped with sail, played an important early role in early human seafaring and warfares. The first advanced mechanical means of marine propulsion was the marine steam engine, introduced in the early 19th century. During the 20th century it was replaced by two-stroke or four-stroke diesel engines, outboard motors, and gas turbine engines on faster ships. Marine nuclear reactors, which appeared in the 1950s, pro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clutch
A clutch is a mechanical device that engages and disengages power transmission, especially from a drive shaft to a driven shaft. In the simplest application, clutches connect and disconnect two rotating shafts (drive shafts or line shafts). In these devices, one shaft is typically attached to an engine or other power unit (the driving member), while the other shaft (the driven member) provides output power for work. Typically the motions involved are rotary, but linear clutches also exist. In a motor vehicle, the clutch acts as a mechanical linkage between the engine and transmission, and briefly disconnects, or separates the engine from the transmission system. This disconnects the drive wheels whenever the clutch pedal is depressed, allowing the driver to smoothly change gears. In a torque-controlled drill, for instance, one shaft is driven by a motor, and the other drives a drill chuck. The clutch connects the two shafts so they may be locked together and spin at the ...

Speed Governor
A governor, or speed limiter or controller, is a device used to measure and regulate the speed of a machine, such as an engine. A classic example is the centrifugal governor, also known as the Watt or fly-ball governor on a reciprocating steam engine, which uses the effect of inertial force on rotating weights driven by the machine output shaft to regulate its speed by altering the input flow of steam. History Centrifugal governors were used to regulate the distance and pressure between millstones in windmills since the 17th century. Early steam engines employed a purely reciprocating motion, and were used for pumping water – an application that could tolerate variations in the working speed. It was not until the Scottish engineer James Watt introduced the ''rotative'' steam engine, for driving factory machinery, that a constant operating speed became necessary. Between the years 1775 and 1800, Watt, in partnership with industrialist Matthew Boulton, produced some 500 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Split Pin
A split pin, also known in the United States of America as a cotter pin or cotter key, is a metal fastener with two tines that are bent during installation, similar to a staple or rivet. Typically made of thick wire with a half-circular cross section, split pins come in multiple sizes and types. The British definition of "cotter pin" is equivalent to U.S. term " cotter". To avoid confusion, the term split cotter is sometimes used for a split pin. A further use of the term "cotter pin" is the "crank cotter pin" used to lock bicycle pedal cranks to the bottom bracket axle. These are not "split" at all and are wedge shaped. Construction A new split pin (see figure A) has its flat inner surfaces touching for most of its length so that it appears to be a split cylinder (figure D). Once inserted, the two ends of the pin are bent apart, locking it in place (figure B). When they are removed they are supposed to be discarded and replaced, because of fatigue from bending. Split pins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (colloquially often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are specially shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Transportation Safety Board Of Canada
The Transportation Safety Board of Canada (TSB, french: Bureau de la sécurité des transports du Canada, BST), officially the Canadian Transportation Accident Investigation and Safety Board (french: link=no, Bureau canadien d'enquête sur les accidents de transport et de la sécurité des transports) is the agency of the Government of Canada responsible for advancing transportation safety in Canada. It is accountable to Parliament directly through the President of the King’s Privy Council and the Minister of Intergovernmental and Northern Affairs and Internal Trade. The independent agency investigates accidents and makes safety recommendations in four modes of transportation: aviation, rail, marine and pipelines. Agency history Prior to 1990, Transport Canada's Aircraft Accident Investigation Branch (1960–1984) and its successor the Canadian Aviation Safety Board or CASB (1984–1990) were responsible for investigation of air incidents. Before 1990, investigations and ac ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transport Canada
Transport Canada (french: Transports Canada) is the department within the Government of Canada responsible for developing regulations, policies and services of road, rail, marine and air transportation in Canada. It is part of the Transportation, Infrastructure and Communities (TIC) portfolio. The current Minister of Transport is Omar Alghabra. Transport Canada is headquartered in Ottawa, Ontario. History The Department of Transport was created in 1935 by the government of William Lyon Mackenzie King in recognition of the changing transportation environment in Canada at the time. It merged three departments: the former Department of Railways and Canals, the Department of Marine, and the Civil Aviation Branch of the Department of National Defence (c. 1927 when it replaced the Air Board) under C. D. Howe, who would use the portfolio to rationalize the governance and provision of all forms of transportation (air, water and land). He created a National Harbours Board and Trans-C ...
