HMS Niobe (1897)
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 o ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. 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 superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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's hull is the vertical distance between the waterline and the bottom of the hull (keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and aft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 extremities 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 cor ...

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 her 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 __NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured para ...

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 mer ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of 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, 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 the 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 ocean ships were broken down, and their average age was ...

Halifax Explosion
On the morning of 6 December 1917, the French cargo ship collided with the Norwegian vessel in the waters of Halifax, Nova Scotia, Canada. The ''Mont-Blanc'', laden with high explosives, caught fire and exploded, devastating the Richmond district of Halifax. 1,782 people were killed, largely in Halifax and Dartmouth, by the blast, debris, fires, or collapsed buildings, and an estimated 9,000 others were injured. The blast was the largest human-made explosion at the time, releasing 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 Belgium to pick up a cargo of relief supplies in New York. On the ''Mont-Blanc'', the impact damaged benzol barrels stored on deck, leaking vapours which were ignited by sparks from the ...

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

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 Disco ...
