HMCS Edmonton
HMCS ''Edmonton'' is a that has served in the Canadian Forces since 1997. ''Edmonton'' is the fourth ship of its class, all of which were built for the Maritime Coastal Defence Vessel Project. The ship is the first vessel to use the designation HMCS ''Edmonton''. The ship is assigned to Maritime Forces Pacific (MARPAC) and is homeported at CFB Esquimalt. Design and description The ''Kingston'' class was designed to fill the minesweeper, coastal patrol and reserve training needs of the Canadian Forces, replacing the s, s and Royal Canadian Mounted Police coastal launches in those roles.Macpherson and Barrie, p. 299 In order to perform these varied duties the ''Kingston''-class vessels are designed to carry up to three ISO containers with power hookups on the open deck aft in order to embark mission-specific payloads.Saunders (2008), p. 95 The seven module types available for embarkation include four route survey, two mechanical minesweeping and one bottom inspection modules.

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 ...

Sister Ship
A sister ship is a ship of the same class or of virtually identical design to another ship. Such vessels share a nearly identical hull and superstructure layout, similar size, and roughly comparable features and equipment. They often share a common naming theme, either being named after the same type of thing or person (places, constellations, heads of state) or with some kind of alliteration. Typically the ship class is named for the first ship of that class. Often, sisters become more differentiated during their service as their equipment (in the case of naval vessels, their armament) are separately altered. For instance, the U.S. warships , , , and are all sister ships, each being an . Perhaps the most famous sister ships were the White Star Line's s, consisting of , and . As with some other liners, the sisters worked as running mates. Other sister ships include the Royal Caribbean International's and . ''Half-sister'' refers to a ship of the same class but with some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hull Classification Symbol (Canada)
The Royal Canadian Navy uses hull classification symbols to identify the types of its ships, which are similar to the United States Navy's hull classification symbol system. The Royal Navy and some European and Commonwealth navies (19 in total) use a somewhat analogous system of pennant numbers. In a ship name such as the ship prefix HMCS for His or Her Majesty's Canadian Ship indicates the vessel is a warship in service to the Monarch of Canada, while the proper name ''Algonquin'' may follow a naming convention for the class of vessel. The hull classification symbol in the example is the parenthetical suffix (DDG 283), where the hull classification type DDG indicates that the ''Algonquin'' is a guided-missile destroyer and the hull classification number 283 is unique within that type. Listed below are various hull classification types with some currently in use and others that are retired and no longer in use. Auxiliary ships * AGOR: Auxiliary General Oceanographic Research ( ...

Esquimalt, British Columbia
The Township of Esquimalt is a municipality at the southern tip of Vancouver Island, in British Columbia, Canada. It is bordered to the east by the provincial capital, Victoria, to the south by the Strait of Juan de Fuca, to the west by Esquimalt Harbour and Royal Roads, to the northwest by the New Songhees 1A Indian reserve and the town of View Royal, and to the north by a narrow inlet of water called the Gorge, across which is the district municipality of Saanich. It is almost tangential to Esquimalt 1 Indian Reserve near Admirals Road. It is one of the 13 municipalities of Greater Victoria and part of the Capital Regional District. Esquimalt had a population of 17,533 in 2021. It covers . It is home to the Pacific fleet of the Royal Canadian Navy. History The region now known as Esquimalt was settled by First Nations people approximately 4000 years before the arrival of Europeans. The treaties of the Hudson's Bay Company (HBC), signed in 1843, refer to these people as t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Commissioning
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 she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, 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 any deficiencies needing co ... [...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 use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Naming And 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 t ...

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] |
Azimuth Thruster
An azimuth thruster is a configuration of marine propellers placed in pods that can be rotated to any horizontal angle (azimuth), making a rudder unnecessary. These give ships better maneuverability than a fixed propeller and rudder system. Types of azimuth thrusters There are two major variants, based on the location of the motor: # Mechanical transmission, which connects a motor inside the ship to the outboard unit by gearing. The motor may be diesel or diesel-electric. Depending on the shaft arrangement, mechanical azimuth thrusters are divided into L-drive and Z-drive. An L-drive thruster has a vertical input shaft and a horizontal output shaft with one right-angle gear. A Z-drive thruster has a horizontal input shaft, a vertical shaft in the rotating column and a horizontal output shaft, with two right-angle gears. # Electrical transmission, more commonly called pods, where an electric motor is fitted in the pod itself, connected directly to the propeller withou ...

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 i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
