Union Rotorua
''Union Rotorua'' was a large ro-ro vessel operated on the trans Tasman route by the Union Steam Ship Company of New Zealand (USSCo). Along with her sister ship ''Union Rotoiti'', she was unusual in that she originally had turbo-electric transmission. Construction ''Union Rotorua'' was built by Broken Hill Pty (BHP) at the Whyalla Steelworks in South Australia. She was launched on 19 January 1976. Delivery was delayed by a year and costs went over-budget by $8 million bringing the total cost to $30 million. It was subsequently acknowledged that ''Rotoiti'' and her sister ship ''Rotorua'' could have been built for half the price if they had been built outside Australia. ''Union Rotorua'' was unusual in that she was powered by gas turbine. The ship's main gas turbine / electric machinery consisted of a single General Electric MM5262RB gas turbine operating on a regenerative cycle. This was coupled to an AC generator to provide a maximum designed continuous rating of 18822 kW ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

General Electric
General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and headquartered in Boston. The company operated in sectors including healthcare, aviation, power, renewable energy, digital industry, additive manufacturing and venture capital and finance, but has since divested from several areas, now primarily consisting of the first four segments. In 2020, GE ranked among the Fortune 500 as the 33rd largest firm in the United States by gross revenue. In 2011, GE ranked among the Fortune 20 as the 14th most profitable company, but later very severely underperformed the market (by about 75%) as its profitability collapsed. Two employees of GE – Irving Langmuir (1932) and Ivar Giaever (1973) – have been awarded the Nobel Prize. On November 9, 2021, the company announced it would divide itself into three investment-grade public companies. On July 18, 2022, GE unveiled the brand names of the companies it will ...

Roll-on/roll-off
Roll-on/roll-off (RORO or ro-ro) ships are cargo ships designed to carry wheeled cargo, such as cars, motorcycles, trucks, semi-trailer trucks, buses, trailers, and railroad cars, that are driven on and off the ship on their own wheels or using a platform vehicle, such as a self-propelled modular transporter. This is in contrast to lift-on/lift-off (LoLo) vessels, which use a crane to load and unload cargo. RORO vessels have either built-in or shore-based ramps or ferry slips that allow the cargo to be efficiently rolled on and off the vessel when in port. While smaller ferries that operate across rivers and other short distances often have built-in ramps, the term RORO is generally reserved for large oceangoing vessels. The ramps and doors may be located in the stern, bow, or sides, or any combination thereof. Description Types of RORO vessels include ferries, cruiseferries, cargo ships, barges, and RoRo service for air deliveries. New automobiles that are transported by ...

Union Steam Ship Company Of New Zealand
Union Steam Ship Company of New Zealand Limited was once the biggest shipping line in the southern hemisphere and New Zealand's largest private-sector employer. It was incorporated by James Mills in Dunedin in 1875 with the backing of a Scottish shipbuilder, Peter Denny. Bought by shipping giant P&O around the time of World War I it was sold in 1972 to an Australasian consortium and closed at the end of the twentieth century. History James Mills James Mills had worked for Johnny Jones and his Harbour Steam Company. After Jones’ death in 1869 Mills tried twice to float a Union Steam Ship Company of New Zealand Limited without attracting enough interest from local investors but in 1875 he found backing from Scottish shipbuilder Peter Denny in return for Union Steam Ship orders for Denny's Dumbarton shipyard. The Denny-built ''Hawea'' and ''Taupo'', both then large by local standards, arrived in mid 1875 and entered service. Union Steam Ship took over the Harbour Steam Com ...

Turbo-electric Transmission
A turbo-electric transmission uses electric generators to convert the mechanical energy of a turbine (steam or gas) into electric energy, which then powers electric motors and converts back into mechanical energy that power the driveshafts. Turbo-electric drives are used in some rail locomotives (gas turbines, ''e.g.'' with the first TGV) and ships (steam and more recently gas turbines). An advantage of turbo-electric transmission is that it allows the adaptation of high-speed turbines to slow turning propellers or wheels without a heavy and complex gearbox. It has the advantage of being able to provide electricity for the ship or train's other electrical systems, such as lighting, computers, radar, and communications equipment. Other advantages for ships include greater watertight subdivision, quieter operations, and safety (via instant thrust reversal by changing engine direct current polarity) for submarines.Friedman, 1994, pp 136, 147–149 Ships with turbo-electric drive ...

Whyalla Steelworks
The Whyalla Steelworks is a fully integrated steelworks and the only manufacturer of rail in Australia. Iron ore is mined in the Middleback Range to feed the steelworks, resulting in the distribution of finished steel products of over 90 different grades. It occupies a 1,000 ha site on the shore of False Bay, Spencer Gulf and is the largest employer in Whyalla, South Australia. Approximately 1.2 million tonnes of raw steel is produced in the steelworks each year, with about 65% of that transferred by rail to Arrium's Market Mills as billets for further processing. The balance of the steel is then converted to finished products at the Whyalla Rolling Mill. These products service the construction and rail transport industries. Dust emissions from the steelworks became a controversial topic in 2005 after legislation was rewritten to nullify a legal battle between OneSteel and the South Australian Environmental Protection Agency. The steelworks is open to the public for guided tours ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Linkspan
A linkspan or link-span is a type of drawbridge used mainly in the operation of moving vehicles on and off a roll-on/roll-off (RO-RO) vessel or ferry, particularly to allow for tidal changes in water level. Linkspans are usually found at ferry terminals where a vessel uses a combination of ramps either at the stern, bow or side to load or unload cars, vans, trucks and buses onto the shore, or alternately at the stern and/or the bow to load or unload railroad cars. History The first linkspans appeared at the end of the 19th century when train ferries came into operation. Each rail ferry berth has to be specifically designed to make sure that it fitted one class of ship. In most of these vessels it was also possible to carry some road vehicles. By the mid 20th century with the rise of road transport, general purpose Ro Ro ferries started to come into service. Most could use the rail ferry berths but generally they were fitted with stern ramps that had the dual function of gi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1998 Auckland Power Crisis
The 1998 Auckland power crisis was a five-week-long power outage affecting the central city of Auckland, New Zealand from 19 February to 27 March 1998. A 1998 ministerial inquiry criticised both the Auckland Electric Power Board and its privatised successor, which had halved its staff after taking over in October 1993. The report blamed risk and asset management and contingency planning, but said reviews of the electricity network were in accordance with industry practice. However, Mercury Energy’s Board had known for 5 years of a potential failure of the power cables, but, instead of also replacing them, took the cost-saving risk of only building a replacement tunnel, which wasn't ready in time. The inquiry report also said, "Internal expertise in 110 kV assets was not maintained at a sufficient level". At the time, almost all of Auckland's central business district was supplied with electricity by Mercury Energy Limited via four 110 kV power cables from the national grid ...
