Wattle Class Crane Stores Lighter
The ''Wattle''-class crane stores lighter consists of three Australian-built lighters which have supported the Royal Australian Navy (RAN) since 1972. The vessels were originally operated by the RAN, but were transferred to DMS Maritime after 1997. Design and construction The design of the ''Wattle''-class crane stores lighters was based on that of the Aircraft/Water Lighter AWL 304. The craft have a catamaran hull, a small bridge and a crane with a maximum capacity of 3 tons. As built, each of the lighters was able to carry up to 30 tons of cargo.Gillett (1988), p. 96 The ''Wattle''-class crane stores lighters were built at Cockatoo Island Dockyard in Sydney. The hulls and bridge sections were built separately in Cockatoo Island's boiler shop, and then joined together at the island's shipyard. Construction of the first craft, CSL 01, began in March 1972 and work on CSL 02 and 03 commenced in May and July of that year respectively.Gillett (1988), p. 97 Service All three ''W ...

Cockatoo Island (New South Wales)
Cockatoo Island is a UNESCO World Heritage Site at the junction of the Parramatta and Lane Cove River in Sydney Harbour, New South Wales, Australia. Cockatoo Island is the largest of several islands that were originally heavily timbered sandstone knolls. Originally the Island rose to above sea level and was but it has been extended to and is now cleared of most vegetation. Called ''Wa-rea-mah'' by the Indigenous Australians who traditionally inhabited the land prior to European settlement, the island may have been used as a fishing base, although physical evidence of Aboriginal heritage has not been found on the island. Between 1839 and 1869, Cockatoo Island operated as a convict penal establishment, primarily as a place of secondary punishment for convicts who had re-offended in the colonies. Cockatoo Island was also the site of one of Australia's biggest shipyards, operating between 1857 and 1991. The first of its two dry docks was built by convicts. Listed on the Na ...

Royal Australian Navy
The Royal Australian Navy (RAN) is the principal naval force of the Australian Defence Force (ADF). The professional head of the RAN is Chief of Navy (CN) Vice Admiral Mark Hammond AM, RAN. CN is also jointly responsible to the Minister of Defence (MINDEF) and the Chief of Defence Force (CDF). The Department of Defence as part of the Australian Public Service administers the ADF. Formed in 1901, as the Commonwealth Naval Forces (CNF), through the amalgamation of the colonial navies of Australia following the federation of Australia. Although it was originally intended for local defence, it became increasingly responsible for regional defence as the British Empire started to diminish its influence in the South Pacific. The Royal Australian Navy was initially a green-water navy, and where the Royal Navy provided a blue-water force to the Australian Squadron, which the Australian and New Zealand governments helped to fund, and that was assigned to the Australia Station. ...

Lighter (barge)
A lighter is a type of flat-bottomed barge used to transfer goods and passengers to and from moored ships. Lighters were traditionally unpowered and were moved and steered using long oars called "sweeps" and the motive power of water currents. They were operated by skilled workers called lightermen and were a characteristic sight in London's docks until about the 1960s, when technological changes made this form of lightering largely redundant. Unpowered lighters continue to be moved by powered tugs, however, and lighters may also now themselves be powered. The term is also used in the Lighter Aboard Ship (LASH) system. The name itself is of uncertain origin, but is believed to possibly derive from an old Dutch or German word, ''lichten'' (to lighten or unload). In Dutch, the word ''lichter'' is still used for smaller ships that take over goods from larger ships. Lighters, albeit powered ones, were proposed to be used in 2007 at Port Lincoln and Whyalla in South Australia t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Diesel Engine
The diesel engine, named after Rudolf Diesel, is an internal combustion engine in which ignition of the fuel is caused by the elevated temperature of the air in the cylinder due to mechanical compression; thus, the diesel engine is a so-called compression-ignition engine (CI engine). This contrasts with engines using spark plug-ignition of the air-fuel mixture, such as a petrol engine ( gasoline engine) or a gas engine (using a gaseous fuel like natural gas or liquefied petroleum gas). Diesel engines work by compressing only air, or air plus residual combustion gases from the exhaust (known as exhaust gas recirculation (EGR)). Air is inducted into the chamber during the intake stroke, and compressed during the compression stroke. This increases the air temperature inside the cylinder to such a high degree that atomised diesel fuel injected into the combustion chamber ignites. With the fuel being injected into the air just before combustion, the dispersion of the fuel is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Catamaran
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowi ...

Cockatoo Island Dockyard
The Cockatoo Island Dockyard was a major dockyard in Sydney, Australia, based on Cockatoo Island. The dockyard was established in 1857 to maintain Royal Navy warships. It later built and repaired military and battle ships, and played a key role in sustaining the Royal Australian Navy. The dockyard was closed in 1991, and its remnants are heritage listed as the Cockatoo Island Industrial Conservation Area. Colonial ownership It was established by the colonial Government of New South Wales, commencing operations in December 1857 with the opening of Fitzroy Dock. Planning had begun as early as May 1846, when Governor George Gipps had recommended the construction of a dry dock at Cockatoo Island to the British government to service Royal Navy vessels. Construction had begun in 1851, with Captain Gother Mann as engineer-in-chief, and taken six years. It was known as the Government Dockyard – Biloela while in colonial control.

Hull (watercraft)
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing cra ...

Darwin, Northern Territory
Darwin ( ; Laragiya language, Larrakia: ) is the List of Australian capital cities, capital city of the Northern Territory, Australia. With an estimated population of 147,255 as of 2019, the city contains the majority of the residents of the sparsely populated Northern Territory. It is the smallest, wettest, and most northerly of the Australian capital cities and serves as the Top End's regional centre. Darwin's proximity to Southeast Asia makes the city's location a key link between Australia and countries such as Indonesia and East Timor. The Stuart Highway begins in Darwin, extends southerly across central Australia through Tennant Creek and Alice Springs, concluding in Port Augusta, South Australia. The city is built upon a low bluff overlooking Darwin Harbour. Darwin's suburbs begin at Lee Point, Northern Territory, Lee Point in the north and stretch to Berrimah, Northern Territory, Berrimah in the east.
