HMCS Niobe
HMS ''Niobe'' was a ship of the of protected cruisers in the Royal Navy. She served in the Boer War and was then given to Canada as the second ship of the newly created Naval Service of Canada as HMCS ''Niobe''. The Naval Service of Canada became the Royal Canadian Navy in August 1911. The ship was nearly lost when she went aground off Cape Sable Island, Nova Scotia overnight 30–31 July 1911. Repairs were completed at the end of 1912 and the ship returned to service in late 1914. During the First World War, ''Niobe'' patrolled the approaches to the St. Lawrence River and then joined the Royal Navy's 4th Cruiser Squadron to patrol off New York City. The cruiser returned to Halifax, Nova Scotia on 17 July 1915 and never put to sea again. ''Niobe'' was paid off in September and served as a depot ship in Halifax. Damaged in the 1917 Halifax Explosion, she was sold for scrap and broken up in the 1920s. Design and description The ''Diadem''-class cruisers were reduced versions of ...

Royal Navy
The Royal Navy (RN) is the naval warfare force of the United Kingdom. It is a component of His Majesty's Naval Service, and its officers hold their commissions from the King of the United Kingdom, King. Although warships were used by Kingdom of England, English and Kingdom of Scotland, Scottish kings from the early Middle Ages, medieval period, the first major maritime engagements were fought in the Hundred Years' War against Kingdom of France, France. The modern Royal Navy traces its origins to the English Navy of the early 16th century; the oldest of the British Armed Forces, UK's armed services, it is consequently known as the Senior Service. From the early 18th century until the World War II, Second World War, it was the world's most powerful navy. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superior ...

Belleville Boiler
There have been a vast number of designs of steam boiler, particularly towards the end of the 19th century when the technology was evolving rapidly. A great many of these took the names of their originators or primary manufacturers, rather than a more descriptive name. Some large manufacturers also made boilers of several types. Accordingly, it is difficult to identify their technical aspects from merely their name. This list presents these known, notable names and a brief description of their main characteristics. See also * Glossary of boiler terminology Boilers for generating steam or hot water have been designed in countless shapes, sizes and configurations. An extensive terminology has evolved to describe their common features. This glossary provides definitions for these terms. Terms which re ...

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer sides of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cora ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship’s carrying capacity, as it excluded the small, often unusable volume contained in its overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition. See also * Length overall Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to ...

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". A merchant vessel has t ...

Ship Breaking
Ship breaking (also known as ship recycling, ship demolition, ship scrapping, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships either as a source of Interchangeable parts, parts, which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking is sustainable, there are concerns about its use by poorer countries without stringent environmental legislation. It is also labour-intensive, and considered one of the world's most dangerous industries. In 2012, roughly 1,250 oce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Halifax Explosion
On the morning of 6 December 1917, the French cargo ship collided with the Norwegian vessel in the harbour of Halifax, Nova Scotia, Canada. ''Mont-Blanc'', laden with Explosive material, high explosives, caught fire and exploded, devastating the Richmond, Nova Scotia, Richmond district of Halifax. At least 1,782 people, largely in Halifax and Dartmouth, Nova Scotia, Dartmouth, were killed by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the Largest artificial non-nuclear explosions#Largest accidental artificial non-nuclear explosions by magnitude, largest human-made explosion at the time. It released the equivalent energy of roughly . ''Mont-Blanc'' was under orders from the French government to carry her cargo from New York City via Halifax to Bordeaux, France. At roughly 8:45 am, she collided at low speed, approximately one knot (), with the unladen ''Imo'', chartered by the Commission for Relief in Belgi ...

Ship Decommissioning
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 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 correc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New York City
New York, often called New York City (NYC), is the most populous city in the United States, located at the southern tip of New York State on one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with a respective county. The city is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics, and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy. With an estimated population in 2024 of 8,478,072 distributed over , the city is the most densely populated major city in the United States.

4th Cruiser Squadron
The 4th Cruiser Squadron and (also known as Cruiser Force H) was a formation of cruisers of the British Royal Navy from 1907 to 1914 and then again from 1919 to 1946. The squadron was first established in 1907, replacing the North America and West Indies Station. It became a training squadron based in Home waters but which was to make three cruises annually, including to the West Indies. In April 1907 it comprised , , and . On 1 May 1912, the Fourth Cruiser Squadron was renamed the Training Squadron. With the appointment in 1913 of Rear Admiral Christopher Cradock the squadron ceased to be a training squadron and became part of the First Fleet. During World War I, the 4th Cruiser Squadron was commanded by Rear Admiral Christopher Cradock; the squadron was effectively annihilated at the Battle of Coronel 1 November 1914. From April 1919 to 1939, it was in the East Indies The East Indies (or simply the Indies) is a term used in historical narratives of the Age of Discov ...
