Hikitia
''Hikitia'' is a working self-propelled floating steam crane in Wellington, New Zealand. She is thought to be the only working steam crane of her type in the world. She is also the sister ship to the '' Rapaki'', formerly of the Port of Lyttelton, which was put on display at the New Zealand Maritime Museum after being taken out of service, and then scrapped in January 2019. Some parts from ''Rapaki'' were given to ''Hikitia''. Engines Twin screws are driven by surface-condensing direct-drive compound engines which were supplied with steam by a coal-fired Scotch boiler with two furnaces. A similar but oil-fired boiler replaced the original boiler in 1963. In 1980 this was also removed and the present two locally made small modern package boilers were installed. These new boilers produce less steam than the original ones.

Rapaki Steam Crane
The ''Rapaki'' steam crane was a historic boat in New Zealand. On 24 December 1925 the Lyttelton Harbour Board ordered an 80-ton self-propelled floating crane, called ''Rapaki''. She was named after the settlement close to Lyttelton of the same name. She was built at a cost of £42,000. The ''Rapaki'' took 109 days to sail from Greenock to Lyttelton, arriving on 28 July 1926. ''Rapaki'' was one of two steam cranes in New Zealand waters, the other being the ''Hikitia ''Hikitia'' is a working self-propelled floating steam crane in Wellington, New Zealand.

Fleming & Ferguson
Fleming and Ferguson was a Scottish marine engineering and shipbuilding company that traded between 1877 and 1969. History 1877–1914 William Y. Fleming and Peter Ferguson (1840–1911) founded the company in Paisley, Scotland in 1877, making marine steam engines. In 1885 they expanded into shipbuilding by taking over the business and Phoenix Shipyard of H. McIntyre & Co., which had built for Campbell of Kilmun. Fleming and Ferguson became a private company in 1895 and a public limited company in 1898. In 1903 the Ferguson family withdrew from the business and set up their own shipyard, Ferguson Shipbuilders, at Port Glasgow. However, Fleming and Ferguson survived their departure and developed a World-class reputation for reciprocating engines and small ships. In 1889 Fleming and Ferguson built the cargo ship with quadruple-expansion engines. By 1894 Fleming and Ferguson were also making water-tube boilers, which were featured in an article in '' The Engineer''. The firm a ...

Compound Steam Engine
A compound steam engine unit is a type of steam engine where steam is expanded in two or more stages. A typical arrangement for a compound engine is that the steam is first expanded in a high-pressure ''(HP)'' cylinder, then having given up heat and losing pressure, it exhausts directly into one or more larger-volume low-pressure ''(LP)'' cylinders. Multiple-expansion engines employ additional cylinders, of progressively lower pressure, to extract further energy from the steam. Invented in 1781, this technique was first employed on a Cornish beam engine in 1804. Around 1850, compound engines were first introduced into Lancashire textile mills. Compound systems There are many compound systems and configurations, but there are two basic types, according to how HP and LP piston strokes are phased and hence whether the HP exhaust is able to pass directly from HP to LP ( Woolf compounds) or whether pressure fluctuation necessitates an intermediate "buffer" space in the form of a st ...

Merchant Ships Of New Zealand
A merchant is a person who trades in commodities produced by other people, especially one who trades with foreign countries. Historically, a merchant is anyone who is involved in business or trade. Merchants have operated for as long as industry, commerce, and trade have existed. In 16th-century Europe, two different terms for merchants emerged: referred to local traders (such as bakers and grocers) and ( nl, koopman) referred to merchants who operated on a global stage, importing and exporting goods over vast distances and offering added-value services such as credit and finance. The status of the merchant has varied during different periods of history and among different societies. In modern times, the term ''merchant'' has occasionally been used to refer to a businessperson or someone undertaking activities (commercial or industrial) for the purpose of generating profit, cash flow, sales, and revenue using a combination of human, financial, intellectual and physical capit ...

Buildings And Structures In Wellington City
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ships Built On The River Clyde
A ship is a large watercraft that travels the world's oceans and other sufficiently deep Sea lane, waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and purpose. Ships have supported exploration, trade, Naval warfare, warfare, Human migration, migration, colonization, and science. After the 15th century, Columbian Exchange, new crops that had come from and to the Americas via the European seafarers significantly contributed to world population growth. Ship transport is responsible for the largest portion of world commerce. The word ''ship'' has meant, depending on the era and the context, either just a large vessel or specifically a Full-rigged ship, ship-rigged sailing ship with three or more masts, each of which is Square rig, square-rigged. As of 2016, there were more than 49,000 merchant ships, totaling almost 1.8 billion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Cranes
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated steam, superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condensation, condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into work (physics), mechanical work by steam engines such as reciprocating engine, reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sir William Arrol & Co
''Sir'' is a formal honorific address in English for men, derived from Sire in the High Middle Ages. Both are derived from the old French "Sieur" (Lord), brought to England by the French-speaking Normans, and which now exist in French only as part of "Monsieur", with the equivalent "My Lord" in English. Traditionally, as governed by law and custom, Sir is used for men titled as knights, often as members of orders of chivalry, as well as later applied to baronets and other offices. As the female equivalent for knighthood is damehood, the female equivalent term is typically Dame. The wife of a knight or baronet tends to be addressed as Lady, although a few exceptions and interchanges of these uses exist. Additionally, since the late modern period, Sir has been used as a respectful way to address a man of superior social status or military rank. Equivalent terms of address for women are Madam (shortened to Ma'am), in addition to social honorifics such as Mrs, Ms or Miss. Etymol ...

Package Boiler
A package boiler is a factory-made boiler. Package boilers are available in a range of standard designs. Package boilers are used for heating and act as a steam generator for small power purposes such as self-powered industrial plants. Package boilers are low pressure designs. A low pressure means low temperature water in the heat exchanger. The large difference between the flame temperature and the heat exchanger discards most of the available entropy. Discarding most of the entropy caps the thermodynamic efficiency below the range needed to make a low pressure boiler suitable for a co-generation plants even when the available capacity is adequate for the application. Advantages of package boilers are that they can be delivered and installed as a complete insulated assembly that doesn’t require a large exclusion zone around itself. The required steam, water, fuel, and electrical connections can be made rapidly. These boilers are inexpensive to operate because their automatic bur ...

Surface Condenser
A surface condenser is a water-cooled shell and tube heat exchanger installed to condense exhaust steam from a steam turbine in thermal power stations. These condensers are heat exchangers which convert steam from its gaseous to its liquid state at a pressure below atmospheric pressure. Where cooling water is in short supply, an air-cooled condenser is often used. An air-cooled condenser is however, significantly more expensive and cannot achieve as low a steam turbine exhaust pressure (and temperature) as a water-cooled surface condenser. Surface condensers are also used in applications and industries other than the condensing of steam turbine exhaust in power plants. Purpose In thermal power plants, the purpose of a surface condenser is to condense the exhaust steam from a steam turbine to obtain maximum efficiency, and also to convert the turbine exhaust steam into pure water (referred to as steam condensate) so that it may be reused in the steam generator or boiler as boiler ...

Paisley, Renfrewshire
Paisley ( ; sco, Paisley, gd, Pàislig ) is a large town situated in the west central Lowlands of Scotland. Located north of the Gleniffer Braes, the town borders the city of Glasgow to the east, and straddles the banks of the White Cart Water, a tributary of the River Clyde. Paisley serves as the administrative centre for the Renfrewshire council area, and is the largest town in the historic county of the same name. It is often cited as "Scotland's largest town" and is the fifth largest settlement in the country, although it does not have city status. The town became prominent in the 12th century, with the establishment of Paisley Abbey, an important religious hub which formerly had control over other local churches. By the 19th century, Paisley was a centre of the weaving industry, giving its name to the Paisley shawl and the Paisley pattern. The town's associations with political radicalism were highlighted by its involvement in the Radical War of 1820, with striking ...

New Zealand Maritime Museum
The New Zealand Maritime Museum Hui Te Ananui A Tangaroa is a maritime museum in Auckland, New Zealand. It is located on Hobson Wharf, adjacent to the Viaduct Harbour in central Auckland. It houses exhibitions spanning New Zealand's maritime history, from the first Polynesian explorers and settlers to modern day triumphs at the America's Cup. Its Maori name is '' 'Te Huiteanaui-A-Tangaroa' '' – holder of the treasures of Tangaroa (the Sea God). History The museum's founding director was Rodney Wilson, who from 1989 led fundraising efforts to establish the museum, which opened in 1993, the year the America's Cup regatta was held in Auckland. The cost was estimated at NZ$11.1 million. The entrance of the museum incorporates the Launchman's Building, a structure built in 1920 which formerly housed a number of small boating companies.
