SS Columbia (1913)
SS ''Katoomba'' was a Passenger ship, passenger steamship that was built in Ireland 1913, spent most of her career in Australian ownership and was scrapped in Japan in 1959. McIlwraith, McEacharn & Co owned her for more than three decades, including two periods when she was a troopship. In 1946 the Basil Goulandris, Goulandris brothers bought her for their Greek Line and registered her in Panama. In 1949 she was renamed ''Columbia''. In Australian civilian service ''Katoomba'' mostly worked scheduled coastal routes, initially between Port Jackson, Sydney and Fremantle Harbour, Fremantle. For Greek Line she mostly worked Transatlantic crossing, transatlantic routes between Europe and North America, and her passengers included European emigrants. Between 1947 and 1949 Compagnie Générale Transatlantique (CGT) Chartering (shipping), chartered her for service between France and the French West Indies. The ship was refitted in 1920, 1946 and 1949. She was a coal-burner until her 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fremantle Harbour
Fremantle Harbour is Western Australia's largest and busiest general cargo port and an important historical site. The inner harbour handles a large volume of sea containers, vehicle imports and livestock exports, cruise shipping and naval visits, and operates 24 hours a day. It is located adjacent to the city of Fremantle, in the Perth metropolitan region. Fremantle Harbour consists of the Inner Harbour, which is situated on the mouth of the Swan River (Western Australia), Swan River; the Fremantle Outer Harbour, Outer Harbour, which is south at Kwinana Beach, Western Australia, Kwinana in Cockburn Sound and handles bulk cargo ports, grain, petroleum, liquefied petroleum gas, alumina, mineral sands, fertilisers, sulphur and other bulk commodities; and Gage Roads, which is the anchorage between Rottnest Island and the mainland. The Inner Harbour includes northern and southern wharf, wharves named North Quay and Victoria Quay, Fremantle, Victoria Quay respectively. All of this are ...

Port Of Quebec
The Port of Quebec () is an inland port located in Quebec City, Quebec, Canada. It is the oldest port in Canada, and the second largest in Quebec after the Port of Montreal. History In the 19th century, the Port of Quebec was one of the most important in the world. It played a major role in the development of both the city and of Canada. In 1863, more than 1,600 ships went through the port, transporting almost 25,000 sailors. It was during this era that the shipbuilding industry grew considerably in Quebec City. In the 20th century, the dredging of the Saint Lawrence River between Quebec City and Montreal moved major port activities upstream. Today cruise traffic has replaced much of the former freight traffic.

Passenger Ship
A passenger ship is a merchant ship whose primary function is to carry passengers on the sea. The category does not include cargo vessels which have accommodations for limited numbers of passengers, such as the ubiquitous twelve-passenger freighters once common on the seas in which the transport of passengers is secondary to the carriage of freight. The type does however include many classes of ships designed to transport substantial numbers of passengers as well as freight. Indeed, until recently virtually all ocean liners were able to transport mail, package freight and express, and other cargo in addition to passenger luggage, and were equipped with cargo holds and derricks, kingposts, or other cargo-handling gear for that purpose. Only in more recent ocean liners and in virtually all cruise ships has this cargo capacity been eliminated. While typically passenger ships are part of the merchant marine, passenger ships have also been used as troopships and often are commissi ...

Reefer Ship
A reefer ship is a refrigerated cargo ship typically used to transport perishable cargo, which require air conditioning, temperature-controlled handling, such as fruits, meat, vegetables, dairy products, and similar items. Description ''Types of reefers:'' Reefer ships may be categorised into three types: # Side-door vessels have water-tight ports on the ship's hull, which open into a cargo hold. Elevators or ramps leading from the quay serve as loading and discharging access for the forklifts or conveyors. Inside these access ports or side doors, pallet lifts or another series of conveyors bring the cargo to the respective decks. This special design makes the vessels particularly well suited for inclement weather operations as the tops of the cargo holds are always closed against rain and sun. # Conventional vessels have a traditional cargo operation with top opening hatches and crane (machine), cranes/derrick (lifting device), derricks. On such ships, when facing wet weather, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Propeller
A propeller (often called a screw if on a ship or an airscrew if on an aircraft) is a device with a rotating hub and radiating blades that are set at a pitch to form a helical spiral which, when rotated, exerts linear thrust upon a working fluid such as water or air. Propellers are used to pump fluid through a pipe or duct, or to create thrust to propel a boat through water or an aircraft through air. The blades are shaped so that their rotational motion through the fluid causes a pressure difference between the two surfaces of the blade by Bernoulli's principle which exerts force on the fluid. Most marine propellers are screw propellers with helical blades rotating on a propeller shaft (ship), propeller shaft with an approximately horizontal axis. History Early developments The principle employed in using a screw propeller is derived from stern sculling. In sculling, a single blade is moved through an arc, from side to side taking care to keep presenting the blade to the wat ...

Steam Turbine
A steam turbine or steam turbine engine is a machine or heat engine that extracts thermal energy from pressurized steam and uses it to do mechanical work utilising a rotating output shaft. Its modern manifestation was invented by Sir Charles Parsons in 1884. It revolutionized marine propulsion and navigation to a significant extent. Fabrication of a modern steam turbine involves advanced metalwork to form high-grade steel alloys into precision parts using technologies that first became available in the 20th century; continued advances in durability and efficiency of steam turbines remains central to the energy economics of the 21st century. The largest steam turbine ever built is the 1,770 MW Arabelle steam turbine built by Arabelle Solutions (previously GE Steam Power), two units of which will be installed at Hinkley Point C Nuclear Power Station, England. The steam turbine is a form of heat engine that derives much of its improvement in thermodynamic efficiency from the u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marine Steam Engine
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam turbines and marine diesel engines. History The first commercially successful steam engine was developed by Thomas Newcomen in 1712. The steam engine improvements brought forth by James Watt in the later half of the 18th century greatly improved steam engine efficiency and allowed more compact engine arrangements. Successful adaptation of the steam engine to marine applications in England would have to wait until almost a century after Newcomen, when Scottish engineer William Symington built the world's "first practical steamboat", the '' Charlotte Dundas'', in 1802. ...

Length Overall
Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often reported. T ...

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] |
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] |
Code Letters
Code letters or ship's call sign (or callsign) Mtide Taurus - IMO 7626853"> SHIPSPOTTING.COM >> Mtide Taurus - IMO 7626853/ref> were a method of identifying ships before the introduction of modern navigation aids. Later, with the introduction of radio, code letters were also used as radio call signs. History In 1857, the United Kingdom sponsored the ''Commercial Code of Signals for the Use of All Nations at Sea'', which introduced four letter flag signal codes to identify individual ships. The first vessel to be reported in '' Lloyd's List'' by her letters was the ''Mallard'' (LDPN), off Deal, Kent whilst on a voyage from London to Calcutta, India. The Commercial Code of Signals, c. 1900, was modified to become the International Code of Signals. By the 1860s, individual ships were being allocated code letters in the United States and Europe. From 1874, code letters were recorded in Lloyd's Register as part of each individual vessel's entry in the register. Generally, code lette ...
