Thorbjørn (icebreaker)
Thorbjørn, formerly HMDS Thorbjørn is a large deep sea icebreaker. The ship was originally built for the Royal Danish Navy, along with two others, to serve in the Arctic and Antarctic. The ship was designed to break and navigate in sea ice and was typically in operation with the Navy between December and March during the northern ice season. The ship is in private ownership. The ship was a sister ship to HDMS Danbjørn and HDMS Isbjørn. History Construction of the ship began 12 November 1979 and the ship was launched 1 June 1980. The ship was commissioned with the Danish Navy on 1 January 1996. She was assigned to Division 15, 1st Naval Squadron at Frederikshavn. The icebreaker frequently worked in the waters around Greenland and sometimes cooperated with the Canadian Coast Guard. In 2014, Adelaide Nautical College in Australia attempted to buy the ship but was unsuccessful. In September 2015, it was announced that Thorbjørn had been sold to Nordane Shipping in Svendborg f ...

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 hu ...

Royal Danish Navy
The Royal Danish Navy ( da, Søværnet) is the sea-based branch of the Danish Defence force. The RDN is mainly responsible for maritime defence and maintaining the sovereignty of Danish territorial waters (incl. Faroe Islands and Greenland). Other tasks include surveillance, search and rescue, icebreaking, 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 Dano-Norwegian Navy. Until the 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 War. This can be explained by its strategic location as the NATO member controlling access ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Ice
Sea ice arises as seawater freezes. Because ice is less dense than water, it floats on the ocean's surface (as does fresh water ice, which has an even lower density). Sea ice covers about 7% of the Earth's surface and about 12% of the world's oceans. Much of the world's sea ice is enclosed within the polar ice packs in the Earth's polar regions: the Arctic ice pack of the Arctic Ocean and the Antarctic ice pack of the Southern Ocean. Polar packs undergo a significant yearly cycling in surface extent, a natural process upon which depends the Arctic ecology, including the ocean's ecosystems. Due to the action of winds, currents and temperature fluctuations, sea ice is very dynamic, leading to a wide variety of ice types and features. Sea ice may be contrasted with icebergs, which are chunks of ice shelves or glaciers that calve into the ocean. Depending on location, sea ice expanses may also incorporate icebergs. General features and dynamics Sea ice does not simply grow ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HDMS Danbjørn
HDMS ''Danbjørn'' (sometimes referred to as ''Danbjoern'') was a 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 The Royal Danish Navy ( da, Søværnet) is the sea-based branch of the Danish Defence force. The RDN is mainly responsible for maritime defence and maintaining the sovereignty of Danish territorial waters (incl. Faroe Islands and Greenland). ... 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ice is water frozen into a solid state, typically forming at or below temperatures of 0 degrees Celsius or Depending on the presence of impurities such as particles of soil or bubbles of air, it can appear transparent or a more or less opaque bluish-white color. In the Solar System, ice is abundant and occurs naturally from as close to the Sun as Mercury to as far away as the Oort cloud objects. Beyond the Solar System, it occurs as interstellar ice. It is abundant on Earth's surfaceparticularly in the polar regions and above the snow lineand, as a common form of precipitation and deposition, plays a key role in Earth's water cycle and climate. It falls as snowflakes and hail or occurs as frost, icicles or ice spikes and aggregates from snow as glaciers and ice sheets. Ice exhibits at least eighteen phases ( packing geometries), depending on temperature and pressure. When water is cooled rapidly (quenching), up to three types of amorphous ice can form depending on its hist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greenland
Greenland ( kl, Kalaallit Nunaat, ; da, Grønland, ) is an island country in North America that is part of the Kingdom of Denmark.

Canadian Coast Guard
The Canadian Coast Guard (CCG; french: links=no, Garde côtière canadienne, GCC) is the coast guard of Canada. Formed in 1962, the coast guard is tasked with marine search and rescue (SAR), communication, navigation, and transportation issues in Canadian waters, such as navigation aids and icebreaking, marine pollution response, and support for other Canadian government initiatives. The coast guard operates 119 vessels of varying sizes and 23 helicopters, along with a variety of smaller craft. The CCG is headquartered in Ottawa, Ontario, and is a special operating agency within Fisheries and Oceans Canada (Department of Fisheries and Oceans). Role and responsibility Unlike armed coast guards of some other nations, the CCG is a government marine organization without naval or law enforcement responsibilities. Naval operations in Canada's maritime environment are exclusively the responsibility of the Royal Canadian Navy. Enforcement of Canada's maritime-related federal statutes m ...

Diesel–electric Powertrain
A diesel–electric transmission, or diesel–electric powertrain, is a transmission system for vehicles powered by diesel engines in road, rail, and marine transport. Diesel–electric transmission is based on petrol–electric transmission, a transmission system used for petrol engines. Diesel–electric transmission is used on railways by diesel–electric locomotives and diesel–electric multiple units, as electric motors are able to supply full torque from 0 RPM. Diesel–electric systems are also used in marine transport, including submarines, and on some land vehicles. Description The defining characteristic of diesel–electric transmission is that it avoids the need for a gearbox, by converting the mechanical force of the diesel engine into electrical energy (through an alternator), and using the electrical energy to drive traction motors, which propel the vehicle mechanically. The traction motors may be powered directly or via rechargeable batteries, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
