Siemens to build UK wind turbine factory, create 700 jobs
By Roland Gribben Published: 29 March 2010
German electrical giant Siemens has joined the rush to build a plant
in Britain to produce huge turbines for the batteries of wind farms being built offshore to provide a new source of power. The company plans to invest more than £80m and create 700 jobs on the east coast of England.
Siemens is the fourth manufacturer aiming to take advantage of what
is forecast to be a huge market for turbines. Last week GE, the US conglomerate, said it intended to invest £100m and create 1,900 jobs at its facility in Britain, while Japan’s Mitsubishi has already gained government support for its plant
and Clipper Windpower, another US manufacturer, is in business in the North East.
The Siemens and GE announcements come hard on the heels
of the announcement in last week’s Budget that the Government is providing £60m for a competition aimed at attracting turbine and other “green” investment
to Britain’s ports.
Turbine manufacturers have been pressing for support and the government, anxious to encourage investment to reduce imports, has given way. The closure
of the Vestas turbine plant on the Isle of Wight last year left Britain without
a domestic manufacturer and resulted in orders going abroad, a large number
of them to Siemens plants in Germany.
Britain is on course to become the world’s “wind capital” through offshore developments with a capacity of 32,000 megawatts and investment likely to top £100bn.
There are uncertainties about some of the projects and turbine manufacturers acknowledge that new technology, involving the construction of 100ft long blades, has yet to be tested.
Siemens already employs 17,000 staff in Britain at more than 100 locations, which last year produced a turnover of more than £4bn.

Internal-combustion engine
Electricity does not constitute a prime mover, for however important it may be as a form of energy it has to be derived from a mechanical generator powered by water, steam, or internal combustion. The internal-combustion engine is a prime mover, and it emerged in the 19th century as a result both of greater scientific understanding of the principles of thermodynamics and of a search by engineers for a substitute for steam power in certain circumstances. In an internal-combustion engine the fuel is burned in the engine: the cannon provided an early model of a single-stroke engine; and several persons had experimented
with gunpowder as a means of driving a piston in a cylinder. The major problem was that of finding a suitable fuel, and the secondary problem was that of igniting
the fuel in an enclosed space to produce an action that could be easily and quickly repeated. The first problem was solved in the mid-19th century by the introduction of town gas supplies, but the second problem proved more intractable as it was difficult to maintain ignition evenly. The first successful gas engine was made
by Étienne Lenoir in Paris in 1859. It was modeled closely on a horizontal steam engine, with an explosive mixture of gas and air ignited by an electric spark
on alternate sides of the piston when it was in midstroke position. Although technically satisfactory, the engine was expensive to operate and it was not until the refinement introduced by the German inventor Nikolaus Otto in 1878 that
the gas engine became a commercial success. Otto adopted the four-stroke cycle
of induction-compression-firing-exhaust that has been known by his name ever since. Gas engines became extensively used for small industrial establishments,
which could thus dispense with the upkeep of a boiler necessary in any steam plant, however small.

Fugro system mirrors reality
Fugro simulation of an ROV working on subsea infrastructure
Published: 01/02/2010
One of the greatest challenges that traditionally faces the subsea contractor is unequivocally convincing the client that he has the solution to the challenge.
It may be a new project – installing and commissioning subsea hardware – or it may be a repair to existing production infrastructure that must be done expeditiously. Either way, the work has to be executed in an accurate and timely manner.
Simulating a task is commonplace and the degree of sophistication
of that modelling process has increased over the years. It is an aspect in which Fugro has a deep interest – witness the development of the Eng-Sim solution.
Three years of work have gone into Eng-Sim which, in a nutshell, provides Fugro with the ability to take a construction or repair concept to a client
and provide him with an ability to quickly understand that concept
by demonstrating it onscreen in a manner that takes into account actual onsite conditions – perhaps in several thousand metres of water.
The FugroEng-Sim is an engineering tool that accurately simulates
the hostile underwater environment and brings that to bear from the conceptual design stage through to procedural development.
Depending on data feeds used, it will take into account the full range
of conditions that might prevail in a particular location and for a specific task – tidal and current velocities and direction, sea-floor characteristics, geophysical
and geotechnical conditions, relevant engineering design drawings, and so forth. Even bolt torques can be replicated.
FugroEng-Sim is designed to use real-world data on top of FEAs (Finite Element Analysis), CFDs (Computational Fluid Dynamics) and RAOs (Response Amplitude Operator) to produce 3D models with real-world physical characteristics. It combines this with electrical and hydraulic circuit simulation
for an unparalleled level of realism.
In essence, every step of the task can be tested against such parameters
as it is being progressed. It means that, by the time the proposed solution developed reaches the client, it possess a powerful reality – mirroring the real world.
That way, it becomes possible to maximise the time available to carry out front-end engineering design.
FugroEng-Sim is compatible with every mainstream CAD package, survey suite and tracking system used by the subsea industry to precisely represent
the job site and every onsite asset with a navigable 3D representation.
It then allows the addition of ROVs, ships and any other functional equipment required for an operation to simulate this job-specific scenario in real time.
In the early stages of a new or brownfield development, the FugroEng-Sim allows engineers to rapidly assess new ideas without ever cutting metal. Later
in development, it is used for clash checks and accessibility studies, essentially
a virtual SIT in a situation representative of actual environmental conditions.
Nearer completion, it can be used to help develop and refine procedures; further, the navigable 3D replay can be integrated into the procedural documents for distribution.
This comprehensive digital deliverable is unmatched in familiarising crew with the work site and equipment, as well as historic and impending works.
In addition, the FugroEng-Sim can be used onsite with the use of GPS, DVL, Inertial Nav, USBL and ROV telemetry strings. This data is used to display, in real time, an accurate representation of the scene subsea, to be used as a piloting aid or streamed, along with video, over the internet to onshore experts.
The FugroEng-Sim aids in every aspect of the engineering process;
it clarifies every facet of a job; it mitigates risk at a fraction of the cost
and is invaluable in the training of ROV pilots.

Alternatives to fossil fuels
It may well become a matter of urgency, before the end of the 20th century, that some means of extracting usable power from nuclear fusion be acquired.
At the present rate of consumption, the world’s resources of mineral fuels and of the available radioactive materials used in the present nuclear-power stations will be exhausted within a period of perhaps a few decades. The most attractive alternative is thus a form of energy derived from a controlled fusion reaction
that would use hydrogen from seawater, a virtually limitless source, and that would not create a significant problem of waste disposal. Other sources of energy
that may provide alternatives to mineral fuels include various forms of solar cell, deriving power from the Sun by a chemical or physical reaction such as that
of photosynthesis. Solar cells of this kind are already in regular use on satellites and space probes, where the flow of energy out from the Sun (the solar wind)
can be harnessed without interference from the atmosphere or the rotation of the Earth.

World Oil Reserves at “Tipping Point”
Science Daily (March 26, 2010)
The world’s capacity to meet projected future oil demand is at a tipping point, according to research by the Smith School of Enterprise and the Environment at Oxford University.
There is a need to accelerate the development of alternative energy fuel resources in order to ensure energy security and reduce emissions, says a paper just published in the journal Energy Policy.
The age of cheap oil has now ended as demand starts to outstrip supply
as we head towards the middle of the decade, says the report. It goes on to suggest that the current oil reserve estimates should be downgraded from between
1150–1350 billion barrels to between 850–900 billion barrels, based on recent research. But how can potential oil shortages be mitigated?
Dr Oliver Inderwildi, Head of the Low Carbon Mobility centre at the Smith School, said: “The common belief that alternative fuels such as biofuels could mitigate oil supply shortages and eventually replace fossil fuels is pie in the sky. There is not sufficient land to cater for both food and fuel demand. Instead
of relying on those silver bullet solutions, we have to make better use
of the remaining resources by improving energy efficiency. Alternatives such
as a hydrogen economy and electric transportation are not mature and will only play a major role in the medium to long term”.
Nick Owen, from the Smith School of Enterprise and the Environment, added: “Significant oil supply challenges will be compounded in the near future
by rising demand and strengthening environmental policy. Mitigating
the oil crunch without using lower grade resources such as tar sands is the key
to maintaining energy stability and a low carbon future”.
The Smith School paper also highlights that in the past, political and financial objectives have led to misreporting of oil reserves, which has led
to contradictory estimates of oil reserve data available in the public domain.
Sir David King, Director of the Smith School, commented: “We have to face up to a future of oil uncertainty much like the global economic uncertainty we have faced during the past two years. This challenge will have a longer term effect
on our economies unless swift action is taken by governments and business.
We all recognize that oil is a finite resource. We need to look at other low carbon alternatives and make the necessary funding available for research, development and deployment today if we are to mitigate the tipping point”.
The report also raises the worrying issue that additional demand for oil could be met by non-conventional methods, such as the extraction of oil from Canada’s tar sands. However, these methods have a far higher carbon output than conventional drilling, and have been described as having a double impact on emissions owing to the emissions produced during extraction as well as during usage.

Direct energy-conversion devices
Most of these energy converters, sometimes called static energy-conversion devices, use electrons as their “working fluid” in place of the vapour or gas employed by such dynamic heat engines as the external-combustion and internal-combustion engines mentioned above. In recent years, direct energy-conversion devices have received much attention because of the necessity to develop more efficient ways of transforming available forms of primary energy into electric power. Four such devices – the electric battery, the fuel cell, the thermoelectric generator (or at least its working principle) and the solar cell had their origins
in the early 1800s.
The battery, invented by the Italian physicist Alessandro Volta in 1800, changes chemical energy directly into an electric current. A device of this type has two electrodes, each of which is made of a different chemical. As chemical reactions occur, electrons are released on the negative electrode and made to flow through an external circuit to the positive electrode. The process continues until
the circuit is interrupted or one of the reactants is exhausted. The forerunners
of the modern dry cell and the lead-acid storage battery appeared during the second half of the 19th century.
The fuel cell, another electrochemical producer of electricity, was developed by William Robert Grove, a British physicist, in 1839. In a fuel cell, continuous operation is achieved by feeding fuel (e.g., hydrogen) and an oxidizer (oxygen)
to the cell and removing the reaction products.
Thermoelectric generators are devices that convert heat directly into electricity. Electric current is generated when electrons are driven by thermal energy across a potential difference at the junction of two conductors made
of dissimilar materials. This effect was discovered by Thomas Johann Seebeck,
a German physicist, in 1821. Seebeck observed that a compass needle near a circuit made of different conducting materials was deflected when one of the junctions was heated. He investigated various materials that produce electric energy
with an efficiency of 3 percent. This efficiency was comparable to that of the steam engines of the day. Yet, the significance of the discovery of the thermoelectric effect went unrecognized as a means of producing electricity because of Seebeck’s misinterpretation of the phenomenon as a magnetic effect caused by a difference
in temperature. A basic theory of thermoelectricity was finally formulated during the early 1900s, though no functional generators were developed until much later.
In a solar cell, radiant energy drives electrons across a potential difference
at a semiconductor junction in which the concentrations of impurities are different on the two sides of the junction. What is often considered the first genuine solar cell was built in the late 1800s by Charles Fritts, who used junctions formed
by coating selenium (a semiconductor) with an extremely thin layer of gold
(see Exploiting renewable energy sources below).
Words and expressions:
energy converters – преобразователь энергии
external-combustion – внешнее сгорание
internal-combustion – внутреннее сгорание
primary energy – первичная энергия
thermoelectric generator – термоэлектрический генератор
