Kigoriak
''Kigoriak'' ( rus, Кигориак) is a Russian icebreaking anchor handling tug supply vessel. Built by Saint John Shipbuilding & Dry Dock Company for Canadian Marine Drilling (Canmar) in 1979 as ''Canmar Kigoriak'', she was the first commercial icebreaking vessel developed to support offshore oil exploration in the Beaufort Sea. When Canmar's icebreaker fleet was sold in 1997, the vessel's name was shortened to ''Kigoria'' and she was reflagged to Liberia. For the next six years, International Transport Contractors used the icebreaker mainly for ocean towage and salvage operations in the Atlantic Ocean. The vessel changed hands again in 2003 when she was sold to her current owner, FEMCO Group, and renamed first ''Talagy'' (Russian: ''Талаги'') and, in 2010, ''Kigoriak''. After more than four decades of service, ''Kigoriak'' was sold for scrap in January 2022. History Development and construction In the mid-1970s, Canadian Marine Drilling (Canmar), the drillin ...

Saint John Shipbuilding
Saint John Shipbuilding was a Canadian shipbuilding company located in Saint John, New Brunswick. The shipyard was active from 1923 to 2003. History Numerous shipyards were located on the shores of Courtney Bay in the east end of Saint John Harbour where extensive mud flats dried at low tide. In 1918 it was announced that the St. John Drydock & Shipbuilding Co. would be established as a subsidiary of the Canada Dredging Co., Ltd. of Midland, Ontario and would construct the largest drydock in the world. The new shipyard with its massive drydock opened in 1923 at a location on the eastern shore of Courtney Bay. The first of its long list of vessels, the ferry MV Kipawo, which still exists, was launched on December 5, 1924. After fit-up, it went into service in 1926.Shipbuildinghistory.com"Saint John Shipbuilding, East Saint John NB", Accessed March 10, 2010 The shipyard was sold in the 1950s to the industrialist K.C. Irving. The ensuing corporate restructuring saw the compan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dome Petroleum
Dome Petroleum Limited was a Calgary-based oil and gas company. Founded in 1950 as a subsidiary of the Toronto company Dome Mines Limited, Dome was built by Jack Gallagher, who remained with the company until 1983. In 1988 Dome was purchased by Amoco. History Jack Gallagher joined a group of investors in Dome Exploration (Western) Ltd. in 1950 and built it into the major Canadian oil company Dome Petroleum Limited (to which it was renamed in 1958). Gallagher was the sole employee for the first two years. However, James McCrea, who was instrumental in building Dome Mines into one of the giants of the Canadian mining industry, is credited with originally creating Dome Exploration (Western) Ltd. Charles Dunkley was Dome's third employee and became Dome's Senior Vice President and Jack's management partner. "Charlie" had a reserved management style and the pair worked well together especially in the early days when they ran a tight management ship. Dome grew by making acquisitions ...

Controllable Pitch Propeller
In marine propulsion, a variable-pitch propeller is a type of propeller with blades that can be rotated around their long axis to change the blade pitch. Reversible propellers—those where the pitch can be set to negative values—can also create reverse thrust for braking or going backwards without the need to change the direction of shaft revolution. A controllable pitch propeller (CPP) can be efficient for the full range of rotational speeds and load conditions, since its pitch will be varied to absorb the maximum power that the engine is capable of producing. When fully loaded, a vessel will need more propulsion power than when empty. By varying the propeller blades to the optimal pitch, higher efficiency can be obtained, thus saving fuel. A vessel with a VPP can accelerate faster from a standstill and can decelerate much more effectively, making stopping quicker and safer. A CPP can also improve vessel maneuverability by directing a stronger flow of water onto the ru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ice Management
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 it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Drift Ice
Drift ice, also called brash ice, is sea ice that is not attached to the shoreline or any other fixed object (shoals, grounded icebergs, etc.).Leppäranta, M. 2011. The Drift of Sea Ice. Berlin: Springer-Verlag. Unlike fast ice, which is "fastened" to a fixed object, drift ice is carried along by winds and sea currents, hence its name. When drift ice is driven together into a large single mass (>70% coverage), it is called pack ice. Wind and currents can pile up that ice to form ridges up to tens of metres in thickness. These represent a challenge for icebreakers and offshore structures operating in cold oceans and seas. Drift ice consists of ice floes, individual pieces of sea ice or more across. Floes are classified according to size: ''small'' – to ; ''medium'' – to ; ''big'' – to ; ''vast'' – to ; and ''giant'' – more than . Drift ice affects: * Security of navigation * Climatic impact (see Polar ice packs) * Geological impact * Biosphere influence (see Ecol ...

Canadian Dollar
The Canadian dollar ( symbol: $; code: CAD; french: dollar canadien) is the currency of Canada. It is abbreviated with the dollar sign $, there is no standard disambiguating form, but the abbreviation Can$ is often suggested by notable style guides for distinction from other dollar-denominated currencies. It is divided into 100 cents (¢). Owing to the image of a common loon on its reverse, the dollar coin, and sometimes the unit of currency itself, are sometimes referred to as the ''loonie'' by English-speaking Canadians and foreign exchange traders and analysts. Accounting for approximately 2% of all global reserves, the Canadian dollar is the fifth-most held reserve currency in the world, behind the U.S. dollar, the euro, the yen and sterling. The Canadian dollar is popular with central banks because of Canada's relative economic soundness, the Canadian government's strong sovereign position, and the stability of the country's legal and political systems.

Arctic Offshore Design (company)
The Arctic ( or ) is a polar regions of Earth, polar region located at the northernmost part of Earth. The Arctic consists of the Arctic Ocean, adjacent seas, and parts of Canada (Yukon, Northwest Territories, Nunavut), Danish Realm (Greenland), Finland, Iceland, Norway, Russia (Murmansk Oblast, Murmansk, Siberia, Nenets Autonomous Okrug, Nenets Okrug, Novaya Zemlya), Sweden and the United States (Alaska). Land within the Arctic region has seasonally varying snow and sea ice, ice cover, with predominantly treeless permafrost (permanently frozen underground ice) containing tundra. Arctic seas contain seasonal sea ice in many places. The Arctic region is a unique area among Earth's ecosystems. The cultures in the region and the Arctic indigenous peoples have adapted to its cold and extreme conditions. Life in the Arctic includes zooplankton and phytoplankton, fish and marine mammals, birds, land animals, plants and human societies. Arctic land is bordered by the subarctic. De ...
