HMAS Swan (D61)
HMAS ''Swan'' was a of the Royal Australian Navy (RAN). One of six built for the RAN, ''Swan'' was built at Cockatoo Island Dockyard, and entered service in 1916. The early part of the ship's career was spent on blockade duty in the Far East, before she was transferred to the Mediterranean for anti-submarine duty. Apart from performing shore bombardment during the Battle of Durazzo (1918), Second Battle of Durazzo, ''Swan''s wartime career was uneventful. The destroyer was placed in reserve in 1920, but was reactivated between 1925 and 1927 and assigned to Tasmania. ''Swan'' was decommissioned in 1928, stripped of parts, and sold for use as prisoner accommodation on the Hawkesbury River. After changing hands several times, the hull sank during gale conditions in 1934. Design and construction ''Swan'' was one of six s built for the RAN.Cassells, ''The Destroyers'', p. 117 The destroyer had a displacement of 750 tons, was length overall, long overall and long between perpendic ...

Swan River (Western Australia)
The Swan River () is a river in the south west of Western Australia. The river runs through the metropolitan area of Perth, Western Australia's capital and largest city. Course of river The Swan River estuary flows through the city of Perth. Its lower reaches are relatively wide and deep, with few constrictions, while the upper reaches are usually quite narrow and shallow. The Swan River drains the Avon and coastal plain catchments, which have a total area of about . It has three major tributaries, the Avon River, Canning River and Helena River. The latter two have dams (Canning Dam and Mundaring Weir) which provide a sizeable part of the potable water requirements for Perth and the regions surrounding. The Avon River contributes the majority of the freshwater flow. The climate of the catchment is Mediterranean, with mild wet winters, hot dry summers, and the associated highly seasonal rainfall and flow regime. The Avon rises near Yealering, southeast of Perth: it me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wreck Diving
Wreck diving is recreational diving where the wreckage of ships, aircraft and other artificial structures are explored. Although most wreck dive sites are at shipwrecks, there is an increasing trend to scuttle retired ships to create artificial reef sites. Diving to crashed aircraft can also be considered wreck diving. The recreation of wreck diving makes no distinction as to how the vessel ended up on the bottom. Some wreck diving involves penetration of the wreckage, making a direct ascent to the surface impossible for a part of the dive. Reasons for diving wrecks A shipwreck may be attractive to divers for several reasons: * it serves as an artificial reef, which creates a habitat for many types of marine life * it often is a large structure with many interesting parts and machinery, which is not normally closely observable on working, floating vessels * it often has an interesting history * it presents new skill challenges for scuba divers to manage the risks associat ...

Ship Breaking
Ship-breaking (also known as ship recycling, ship demolition, ship dismantling, or ship cracking) is a type of ship disposal involving the breaking up of ships for either a source of parts Part, parts or PART may refer to: People *Armi Pärt (born 1991), Estonian handballer * Arvo Pärt (born 1935), Estonian classical composer *Brian Part (born 1962), American child actor *Dealtry Charles Part (1882–1961), sheriff (1926–1927) a ..., which can be sold for re-use, or for the extraction of raw materials, chiefly scrap. Modern ships have a lifespan of 25 to 30 years before corrosion, Fatigue (material), metal fatigue and a lack of parts render them uneconomical to operate. Ship-breaking allows the materials from the ship, especially steel, to be recycling, recycled and made into new products. This lowers the demand for mined iron ore and reduces energy use in the steelmaking process. Fixtures and other equipment on board the vessels can also be reused. While ship-breaking i ...

Peat Island
Peat Island is a small island of approximately eight hectares in the Hawkesbury River, just north of Sydney, New South Wales, Australia. It forms part of the suburb called Mooney Mooney and is located just upstream from the Sydney – Newcastle Freeway bridge. Other islands in the Hawkesbury River include Dangar Island, Spectacle Island (Hawkesbury River), Spectacle Island, Milson Island, Long Island (New South Wales), Long Island, and Lion Island (New South Wales), Lion Island. History Peat Island was originally known as Rabbit Island, presumably due to the fact that rabbits were being kept there as reported in 1841: "''That to the east is termed Goat Island, having many of those animals grazing thereon, the other Rabbit Island, which is numerously stocked as a Rabbit Warren.''" It was only renamed to Peat Island in 1936, due to its proximity to Peat's Ferry, which at the time was operating between Mooney Mooney and Kangaroo Point on the Hawkesbury. George Peat was an early ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Milson Island
Milson Island is located in New South Wales, Australia. It was first settled over 100 years ago and has been used as a bacteriological station, quarantine station, a hospital to treat soldiers from WWI with venereal disease, mental hospital, a rehab for alcoholics, a women's jail, and now a sports and recreation centre. It is in the middle of the Hawkesbury River, so the only means of transport is by ferry. Some of the activities available at Milson Island include a high ropes course, rock climbing, canoeing, kayaking, archery, bushwalking and abseiling. The accommodation is 3-4 stars with seven lodges (Possum, Koala, Waratah, Kookaburra, Lorikeet, Platypus and Cockatoo) and five holiday units. The camp usually suits two small schools or a big school at the same time. It is a popular place for camps for many schools across Sydney, and families go there for a nice, relaxed and fun retreat. All that is left of the old mental asylum is the nurses' quarters or hospital. When the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Blue Metal
Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. It lies between violet and cyan on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments.

Cowan, New South Wales
Cowan is a small town and suburb near Sydney, in the state of New South Wales, Australia, approximately north of the Sydney central business district, in the local government area of Hornsby Shire. Cowan shares the postcode of 2081 with Berowra. Brooklyn, which lies to the north-east of Cowan, is considered the northernmost suburb of the Greater Sydney Metropolitan Area. History The town takes its name from an Aboriginal word meaning ''big water''. The 1828 census lists two convicts called Cowan, and it is also thought possible that Cowan was named after one of them. Still another suggestion is that it was named after a small town in Scotland.

Hulk (ship)
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to an old ship that has had its rigging or internal equipment removed, retaining only its buoyant qualities. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing. More recently, ships have been hulked when they become obsolete or when they become uneconomical to operate. Sheer hulk A sheer hulk (or shear hulk) wa ...
