HDMS Danbjørn
HDMS ''Danbjørn'' (sometimes referred to as ''Danbjoern'') was a Denmark, Danish icebreaker built for breaking and reporting ice in the sea for Danish Ice Service in 1965. Originally operated by the Ministry of Industrial Affairs, it was incorporated into the Royal Danish Navy on January 1, 1996. ''Danbjørn'' was crewed by naval personnel throughout its history. The ship's mission was to assist shipping to and from Danish ports among these the most important supply and export ports, during ice conditions in the Danish waters within the Skaw. The shipping was assisted as close as possible to their port of destination where the remaining icebreaking is taken over by the port’s own icebreaking resources. Assistance is given according to the following priority: * Ships in distress. * Ships transporting live animals. * Ships transporting passengers. * Ships transporting cargoes of special importance. * All ships in need. The action from ''Danbjørn'' was seen each winter from Dece ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ice is water that is freezing, frozen into a solid state, typically forming at or below temperatures of 0 °Celsius, C, 32 °Fahrenheit, F, or 273.15 Kelvin, K. It occurs naturally on Earth, on other planets, in Oort cloud objects, and as interstellar ice. As a naturally occurring crystalline inorganic solid with an ordered structure, ice is considered to be a mineral. Depending on the presence of Impurity, impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less Opacity (optics), opaque bluish-white color. Virtually all of the ice on Earth is of a Hexagonal crystal system, hexagonal Crystal structure, crystalline structure denoted as ''ice Ih'' (spoken as "ice one h"). Depending on temperature and pressure, at least nineteen phases of ice, phases (Sphere packing, packing geometries) can exist. The most common phase transition to ice Ih occurs when liquid water is cooled below (, ) at standard atmospheric pressure. When water is coo ...

Frederikshavn
Frederikshavn () is a Danish town in Frederikshavn municipality, Region Nordjylland, on the northeast coast on the North Jutlandic Island in northern Denmark. Its name translates to "Frederik's harbor". It was originally named Fladstrand. The town has a population of 22,548 (1 January 2025), and is an important traffic portal with its ferry connections to Gothenburg in Sweden. The town is well known for fishing and its fishing and industrial harbours. Frederikshavn's oldest district, Fiskerklyngen, is originally from the mid-16th century, but the houses now there are from 18th–19th centuries. History Frederikshavn was originally called ''Fladstrand'' (lit. "Flat beach") from its location in Flade parish. Fladstrand The first mention of a settlement is in a letter dated 13 March 1572 found in the Danish chancery letterbooks. It was a fishing village, trading place and crossing point to Norway. The old Fladstrand church was built between 1686 and 1690. On 31 December 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Royal Danish Navy
The Royal Danish Navy (, ) is the Naval warfare, sea-based branch of the Danish Armed Forces force. The RDN is mainly responsible for maritime defence and maintaining the sovereignty of Denmark, Danish territorial waters (incl. Faroe Islands and Greenland). Other tasks include surveillance, search and rescue, Icebreaker, icebreaking, oil spill, oil spill recovery and prevention as well as contributions to international tasks and forces. During the period 1509–1814, when Denmark was in a union with Norway, the Danish Navy was part of the Royal Danish Navy (1510–1814), Dano-Norwegian Navy. Until the Copenhagenization (naval), copenhagenization of the navy in 1801, and again in 1807, the navy was a major strategic influence in the European geographical area, but since then its size and influence has drastically declined with a change in government policy. Despite this, the navy is now equipped with a number of large state-of-the-art vessels commissioned since the end of the Cold ...

Maritime Call Sign
Maritime call signs are call signs assigned as unique identifiers to ships and boats. All radio transmissions must be individually identified by the call sign. Merchant and naval vessels are assigned call signs by their national licensing authorities. History One of the earliest applications of radiotelegraph operation, long predating broadcast radio, were marine radio stations installed aboard ships at sea. In the absence of international standards, early transmitters constructed after Guglielmo Marconi's first transatlantic message in 1901 were issued arbitrary two-letter calls by radio companies, alone or later preceded by a one-letter company identifier. These mimicked an earlier railroad telegraph convention where short, two-letter identifiers served as Morse code abbreviations to denote the various individual stations on the line (for instance, AX could represent Halifax). "N" and two letters would identify U.S. Navy; "M" and two letters would be a Marconi station. On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
International Call Sign
In broadcasting and radio communications, a call sign (also known as a call name or call letters—and historically as a call signal—or abbreviated as a call) is a unique identifier for a transmitter station. A call sign can be formally assigned by a government agency, informally adopted by individuals or organizations, or even cryptographically encoded to disguise a station's identity. The use of call signs as unique identifiers dates to the landline railroad telegraph system. Because there was only one telegraph line linking all railroad stations, there needed to be a way to address each one when sending a telegram. In order to save time, two-letter identifiers were adopted for this purpose. This pattern continued in radiotelegraph operation; radio companies initially assigned two-letter identifiers to coastal stations and stations on board ships at sea. These were not globally unique, so a one-letter company identifier (for instance, 'M' and two letters as a Marconi sta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Icebreaker
An icebreaker is a special-purpose ship or boat designed to move and navigate through ice-covered waters, and provide safe waterways for other boats and ships. Although the term usually refers to ice-breaking ships, it may also refer to smaller vessels, such as the icebreaking boats that were once used on the canals of the United Kingdom. For a ship to be considered an icebreaker, it requires three traits most normal ships lack: a strengthened hull, an ice-clearing shape, and the power to push through sea ice. Icebreakers clear paths by pushing straight into frozen-over water or pack ice. The bending strength of sea ice is low enough that the ice breaks usually without noticeable change in the vessel's trim. In cases of very thick ice, an icebreaker can drive its bow onto the ice to break it under the weight of the ship. A buildup of broken ice in front of a ship can slow it down much more than the breaking of the ice itself, so icebreakers have a specially designed hull ...
