Trawlwire Cutter
Net cutters, or trawlwire cutters, were secret weaponsSæmundsson, Sveinn (1984) ''Guðmundur skipherra Kjærnested'', Örn og Örlygur. eykjavík p. 187-189. employed by the Icelandic Coast Guard during the latter two Cod Wars to cut the trawling wires of foreign fishing trawlers A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets tha ... working within the then newly claimed Exclusive Fisheries zones. They were invented by Commander Pétur Sigurðsson, Director of the Coast Guard, with assistance from Friðrik Teitsson from the Icelandic lighthouse institution and Tómas Sigurðsson, who were both ironmongers. The invention was known as the trawlwire cutter, and was tested in 1958—but not used until 5 September 1972, after every Icelandic ship had been equipped with it. The first net ...

Cod War
The Cod Wars ( is, Þorskastríðin; also known as , ; german: Kabeljaukriege) were a series of 20th-century confrontations between the United Kingdom (with aid from West Germany) and Iceland about fishing rights in the North Atlantic. Each of the disputes ended with an Icelandic victory. Some Icelandic historians view the history of Iceland's struggle for control of its maritime resources in ten episodes, or ten cod wars. Fishing boats from Britain have been sailing to waters near Iceland in search of their catch since the 14th century. Agreements struck during the 15th century started a centuries-long series of intermittent disputes between the two countries. Demand for seafood and consequent competition for fish stocks grew rapidly in the 19th century. The modern disputes or wars began in 1952 after Iceland expanded its territorial waters from 3 to based on a decision by the International Court of Justice. The United Kingdom responded by banning Icelandic ships landing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coal
Coal is a combustible black or brownish-black sedimentary rock, formed as stratum, rock strata called coal seams. Coal is mostly carbon with variable amounts of other Chemical element, elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years. Vast deposits of coal originate in former wetlands called coal forests that covered much of the Earth's tropical land areas during the late Carboniferous (Pennsylvanian (geology), Pennsylvanian) and Permian times. Many significant coal deposits are younger than this and originate from the Mesozoic and Cenozoic eras. Coal is used primarily as a fuel. While coal has been known and used for thousands of years, its usage was limited until the Industrial Revolution. With the invention of the steam engine, coal consumption increased. In 2020, coal supplied about a quarter of the world's primary energ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Military History Of Iceland
This is a brief overview of historical warfare and recent developments in Iceland. Iceland has never participated in a full-scale war or invasion and the constitution of Iceland has no mechanism to declare war. Settlement and commonwealth In the period from the settlement of Iceland, in the 870s, until it became part of the realm of the Norwegian King, military defences of Iceland consisted of multiple chieftains (''Goðar'') and their free followers (''þingmenn'', ''bændur'' or ''liðsmenn'') organised as per standard Nordic military doctrine of the time in expeditionary armies such as the ''leiðangr''. These armies were divided into units by the quality of the warriors and birth. At the end of this period the number of chieftains had diminished and their power had grown to the detriment of their followers. This resulted in a long series of major feuds known as Age of the Sturlungs in the 13th century. During and before the war more than 21 fortresses were built. The battl ...

Torpedo Net
Torpedo nets were a passive ship defensive device against torpedoes. They were in common use from the 1890s until the Second World War. They were superseded by the anti-torpedo bulge and torpedo belts. Origins With the introduction of the Whitehead torpedo in 1873, and the subsequent development of the torpedo boat, new means were sought to protect capital ships against underwater attacks. In 1876 the British Admiralty Torpedo Committee came up with a number of recommendations for combating torpedoes, which included "... nets of galvanised iron hung around each battleship from projecting 40 ft spars". Experiments were conducted in 1877, with becoming the first operational ship to be fitted with the nets. Design and use Torpedo nets could be hung out from the defending ship, when moored or otherwise stationary in the water, on multiple horizontal booms. Each boom was fixed to the ship at one end at or below the edge of the main deck, by a steel pin that permitted the boom to be ...

Svalbard
Svalbard ( , ), also known as Spitsbergen, or Spitzbergen, is a Norway, Norwegian archipelago in the Arctic Ocean. North of continental Europe, mainland Europe, it is about midway between the northern coast of Norway and the North Pole. The islands of the group range from 74th parallel north, 74° to 81st parallel north, 81° north latitude, and from 10th meridian east, 10° to 35th meridian east, 35° east longitude. The largest island is Spitsbergen, followed by Nordaustlandet and . The largest settlement is Longyearbyen. The islands were first used as a base by the Whaling, whalers who sailed far north in the 17th and 18th centuries, after which they were abandoned. Coal mining started at the beginning of the 20th century, and several permanent communities were established. The Svalbard Treaty of 1920 recognizes Norwegian sovereignty, and the 1925 Svalbard Act made Svalbard a full part of the Kingdom of Norway. They also established Svalbard as a free economic zone and a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norwegian Coast Guard
The Norwegian Coast Guard ( no, Kystvakten) is a maritime military force which is part of the Royal Norwegian Navy. The coast guard's responsibility are for fisheries inspection, customs enforcement, border control, law enforcement, shipping inspection, environmental protection, and search and rescue. It operates throughout Norway's exclusive economic zone (EEZ), internal waters and territorial waters. It is headquartered at Sortland Naval Base. In 2013 the Coast Guard had 370 employees, including conscripts, and a budget of 1.0 billion Norwegian krone. The force is subdivided into three main divisions. The Outer Coast Guard covers the EEZ and consists of three ''Nordkapp''-class offshore patrol vessels, three ''Barentshav''-class offshore patrol vessels as well as ''Ålesund'', ''Svalbard'' and ''Harstad''. The Inner Coast Guard consists of five ''Nornen''-class patrol vessels. The Coast Guard has air support of the P-3 Orion patrol aircraft operated by the Royal Norw ...

Fire Axe
An axe ( sometimes ax in American English; see spelling differences) is an implement that has been used for millennia to shape, split and cut wood, to harvest timber, as a weapon, and as a ceremonial or heraldic symbol. The axe has many forms and specialised uses but generally consists of an axe head with a handle, or ''helve''. Before the modern axe, the stone-age hand axe without a handle was used from 1.5 million years BP. Hafted axes (those with a handle) date only from 6000 BC. The earliest examples of handled axes have heads of stone with some form of wooden handle attached ( hafted) in a method to suit the available materials and use. Axes made of copper, bronze, iron and steel appeared as these technologies developed. The axe is an example of a simple machine, as it is a type of wedge, or dual inclined plane. This reduces the effort needed by the wood chopper. It splits the wood into two parts by the pressure concentration at the blade. The handle of the axe a ...

Waste
Waste (or wastes) are unwanted or unusable materials. Waste is any substance discarded after primary use, or is worthless, defective and of no use. A by-product, by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product's value above zero. Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes ( feces and urine) and surface runoff), radioactive waste, and others. Definitions What constitutes waste depends on the eye of the beholder; one person's waste can be a resource for another person. Though waste is a physical object, its generation is a physical and psychological process. The definitions used by various agencies are as below. United Nations Environment Program According to the Basel Convention on the Control of Transboundary Movements of Hazardous Wastes ...

OPV (naval)
A patrol boat (also referred to as a patrol craft, patrol ship, or patrol vessel) is a relatively small naval vessel generally designed for coastal defence, border security, or law enforcement. There are many designs for patrol boats, and they generally range in size. They may be operated by a nation's navy, coast guard, police, or customs, and may be intended for marine (" blue water"), estuarine (" green water"), or river (" brown water") environments. Per their name, patrol boats are primarily used to patrol a country's exclusive economic zone (EEZ), but they may also be used in other roles, such as anti- smuggling, anti-piracy, fishery patrols, immigration law enforcement, or search and rescue. Depending on the size, organization, and capabilities of a nation's armed forces, the importance of patrol boats may range from minor support vessels that are part of a coast guard, to flagships that make up a majority of a navy's fleet. Their small size and relatively low cost mak ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
