Emerson sells millionth valve controller unit

Emerson Process Management sales offices have sold its one millionth Fieldvue digital valve controller worldwide.

First introduced in 1994, the product and its digital communication and diagnostic capabilities changed the way process control manufacturers monitor control valves, and accelerated the process industry’s move to digital instrumentation. A process control plant, regardless of industry, makes money based on its ability to minimize or eliminate variability and maximize uptime.

By monitoring valves and enabling predictive maintenance, Fieldvue instruments support both of these goals à‚— with a market-leading level of precision. Danny Nelson, vice president of instruments for the Fisher division, was a mechanical test engineer in the mid-1990s, supporting the new Fieldvue instrument design.

“From the early inception of the product, we focused on Fisher core product valuesà‚–reliability and performance,” he said. Because the Fieldvue instrument was the first communicating, loop-powered digital positioner, several new tests were developed to verify technologies deployed in the product.

With its introduction, the Fieldvue instrument platform received several industry awards and resulted in more than 50 patents for its innovation and reliability. By 1999, the installed base of 100 000 Fieldvue DVC5000 instruments had delivered one billion hours of run-time in process plant environments.

Over the past decade, the global development team has added numerous enhancements and application options for Fieldvue instruments, from online diagnostics to remote mounting. Emerson personnel developed a stainless steel version for use in harsh, offshore environments that can withstand temperatures up to 120 à‚°C.

Ken Hall, Fieldvue product marketing manager, said, “The more capability we built into the instrument, the greater the application flexibility and customer interest we generated.”

This coal fired power station, originally owned by Welsh Power, but now a Scottish and Southern Energy facility, has three 131 MW generators, which supply power to Newport and surrounding areas.

Prior to the upgrade, other types of monitoring equipment were being used, including GEC Type 6 turbine supervisory systems and Alstec Type 7 equipment for vibration monitoring.

Engineers at Uskmouth acknowledged that both these systems were obsolete and this was causing problems in terms of support and reliability of operation. As part of the upgrade, Sensonics supplied and fitted its Aegis VME (Vibration) and Sentry turbine monitoring systems to the turbine and alternator.

The vibration sensors fitted included Sensonics PZV2 piezo-electric velocity transducers. These units were selected, rather than accelerometers, based on their superior noise performance in heavy industrial environments and unique internal signal processing, which eliminates the potential for resonances through such causes as steam noise.

They also offer an advantage over traditional moving coil velocity transducers with a high frequency response and no moving parts.

As a result of installing the new monitoring equipment the problems associated with the previous system have been eliminated and the engineers at Uskmouth are appreciating the reliability and state-of-the-art features of the Sensonics equipment.

John Phillips, instrumentation engineer at Uskmouth added, “The high build quality of the Sensonics equipment is particularly appreciated and the modular design of the units makes the system easy to support and expand if needed in the future.”

UK-based Sensonics is a leading supplier of turbine supervisory and high integrity protection equipment to the power industry.

Scottish subsea cable installer Subocean Group wins leading renewables business award

UK renewable energy company Subocean Group has won a top renewables accolade at a prestigious business awards ceremony.

The group, which specializes in high performance subsea cable installation and burial solutions, was named the ‘Best Renewable Energy Company’ at the Aberdeen and Grampian Chamber of Commerce’s Northern Star awards.

“We hope Subocean inspires other companies in the Northeast Scotland to consolidate their oil and gas expertise for the future prosperity of the region and, indeed, towards achieving Scotland and Europe’s renewable targets.” The renewable energy award recognizes a company that can best demonstrate its success in developing and securing new business using innovative technology, equipment and business processes.

Subocean Group is playing a vital role towards positioning Aberdeen and, indeed, Scotland as a global leader in renewable energy by pushing the boundaries of marine and offshore wind sectors.

The company has successfully become one of the UK’s market leaders in the renewables sector after carving out a niche for itself as a specialist in high performance subsea cable installation and burial solutions. Previously, Scotland’s Subocean Group has won high-profile contracts and is making substantial investments in the future.

In the past 12 months, the company has surpassed its estimated annual growth of à‚£40m ($65m) worth of renewables contracts by à‚£100m, underlining its success particularly during challenging economic times. It has also created 75 new jobs and doubled the size of its Aberdeen headquarters.

Subocean said that it recognized the enormous potential for renewable energy as early as 2005, when it established its subsea construction company.

The company developed a business strategy, which included transferring its oil and gas expertise to the renewables sector, as well as progressively making substantial investments in people and specialist equipment.

Allison Engineering says its instruments comply with highest nuclear specifications

The re-emergence of interest in nuclear power as a competitive and viable energy source has focused the attention of design engineers, plant engineers and operators in improving plant performance for new, existing and re-licensed nuclear power facilities worldwide.

The next generation of nuclear power plants will achieve even greater efficiencies, lower operational costs, reduced maintenance and most importantly, improved safety. Among the key components playing an important role in improved safety and greater efficiency in these plants are flow and level instruments, which need to meet the unique and challenging demands associated with nuclear power generation.

Allison Engineering offers a range of FCI thermal dispersion flow and level instruments that are claimed to be the only thermal dispersion devices with both the Nuclear IEEE Cat.1E accreditation and SIL2 compliance.

In the UK, Allison Engineering has supplied FCI level solutions for both radwaste interface (radioactive waste slurry interface) and sump level applications. Worldwide, FCI level and flow instruments are installed in over 115 nuclear power plants and these are operating in over 30 different applications including, analyzer sampling systems, flood alarm, turbine water level, chemical injection, pump protection, condenser off gas flow and reactor core coolant.

With its experience and the ongoing commitment to the nuclear qualifications of its instruments, Allison offer flow and level solutions for a variety of new-build and decommissioning applications. Fundamental to FCI’s thermal dispersion technology is a probe with two thermowell protected platinum RTD temperature sensors in the process stream.

One RTD is heated while the other senses the actual process temperature. The temperature difference between these sensors is measured, which is directly proportional to mass flow. From this reading, a variety of outputs can be provided, including simple level/flow switching, multi-point level and gas mass-flow. The FCI Thermal dispersion design offers fast response and accuracy. With no moving parts, it is virtually maintenance free, saving time and money, and is inherently multi-variable, measuring both flow/level and temperature.

The groundbreaking Western Bioenergy Plant at Port Talbot, Wales, developed by EcO2 Limited in a joint venture with the Western Log Group, cost à‚£33m ($54m) to build.

Funded by Good Energies Investments Limited and supported by the Welsh Assembly European Funding Office and the UK’s Department of Business Innovationa & Skills the plant is now up and running following a two-year construction project. It burns clean wood waste from sustainable forestry sources to generate up to 13.8 MW of power, supplied to local homes and businesses.

All pipework services for the project were carried out by Industrial Pipework UK Limited (IPL) of Maesteg, South Wales. This included water, natural gas and compressed air systems supporting the plant’s process and generation technology. The company chose Pipe Center’s Press-Fit pipework connection system due to its exceptional speed and effectiveness.

Mark Waldron, IPL’s managing director, said: “It’s an excellent system, and saves significant time and manpower on-site. It played an important role in helping us deliver the project within the time-scale. “We were also very keen on the quality of the finish. Although it is very quick to install, the end result looks superb. In our experience it is also extremely reliable. We have not had a single leak on the project, which says a lot about the quality and effectiveness of the product.”

The plant takes surplus wood waste from local sawmills and forests that would otherwise be thrown away, and turns it into clean electricity. Pipework and components for the project were supplied by Pipe Center’s Cardiff branch.

John Walker, national industrial sales manager, said: “The project is an excellent example of sustainable technology that is both good for the environment and good for business. It not only works beautifully, it also looks superb.”

Turbomachinery software package gets upgrade

Concepts NREC has launched its Agile Engineering Design System 2009 (Agile 2009) turbomachinery software package.

Click here to enlarge image

Upgraded with over 40 new computer-aided engineering (CAE) features and enhancements, Agile 2009 provides turbomachinery engineers with new design and analysis capabilities. The upgrades were developed in response to input from the Agile software user group, for the benefit of existing and new users.

The Concepts NREC Agile Engineering Design System software covers all aspects of turbomachinery design and analysis. Its integrated CAE tools help in the development of rotating machinery like turbines, compressors, fans and pumps from preliminary design, detailed design, computational fluid dynamics (CFD) and finite element analysis (FEA) to optimization.

Some of the new features and upgrades in Agile 2009 include Pushbutton CFD volute support, integrated FEA, global grid smoothing, mixed grid topologies and mass-flow boundary conditions. To provide a previously missing piece in the turbomachinery engineering puzzle, the Agile 2009 Pushbutton CFD volute solution was developed by Concepts NREC using its own research funds in response to the notorious industry-wide expense of laying out volutes. The integrated FEA stress analysis capabilities in Agile 2009 consolidate turbomachinery engineering, design and analysis tools.

Designers can now weigh all variables earlier in the process, saving time and money by eliminating the need for ‘back-and-forth’ between aerodynamics and stress analysis teams, which in turn reduces errors and leads to better trade-off studies. Enhancements include global grid smoothing and mixed grid topologies that allow for better grid quality for fully integrated turbomachinery engineering, design and analysis. Combining these technologies into one design system gives engineers enormous advantages by helping to achieve better end results in less time.

Mass-flow boundary conditions allow for solutions to be set to converge to specific mass flows. Additionally, mass flow boundary conditions can increase solutions ranges. This enables engineers to develop more complex, yet more efficient turbomachinery designs.

3M ACCR overcomes land permission problems for connecting offshore wind farms to the onshore power grid in the UK

3M, the diversified technology company, has announced the UK launch of 3M ACCR (Aluminium Conductor Composite Reinforced), a breakthrough in overhead power transmission. 3M ACCR is designed as a ‘drop-in’ replacement for existing electrical conductors and can as much as double the transmission capacity of the line.

Click here to enlarge image

This could help the UK power industry to meet the government’s renewable energy targets and overcome some of the issues of connecting offshore wind farms to the onshore grid, in particular delays caused by planning objections.

Ofgem has identified three main barriers to renewable energy deployment: a shortage of turbines, access to the high voltage transmission system and planning objections. 3M ACCR helps address the latter two barriers and its launch in the UK coincides with the current à‚£15bn ($24.5bn) tender process from Ofgem and DECC for new cabling to connect offshore wind farms.

3M ACCR could help remote outposts of land-based power networks near a new offshore wind-farm to be upgraded from their low capacity, end-of-the-line role. In turn, this could contribute to them becoming the start of a high capacity network flowing in the opposite direction to the National Grid. By using existing transmission routes, no new land permissions would be required.

Most of the National Grid is based on steel core conductors which have design limitations on how much current they can carry. Many existing transmission lines were designed and installed years ago and are now thermally constrained, which affects the amount of power that can be transmitted before impaired performance.

With its advanced multi-strand aluminium composite core design, 3M ACCR has the strength and stiffness of steel core conductors, but weighs half as much and is able to continuously handle 210 à‚°C (and in an emergency 240 à‚°C), with considerably less sag than traditional conductors. Using 3M ACCR can avoid the need for rebuilding or addition of new substations and it does not require the height of existing pylons to be raised in order to increase clearance levels. This leads to minimal impact on the environment and helps to overcome the delays frequently caused by planning objections from pressure groups and land owners.

3M ACCR is an award-wining product that has already been installed in more than 20 power networks worldwide. Awards for 3M ACCR include an R&D 100 Award from R&D Magazine in the USA as ‘one of the most technologically significantly products introduced into the marketplace’.

In the UK, it will be aimed primarily at supporting 110-400kV power transmission. In addition to enabling offshore wind farms to connect to national power networks, 3M ACCR has other benefits.

These include providing additional capacity in urban areas – where rebuilding existing infrastructures may be difficult and helping to maintain service during line failure à‚— some power firms use 3M ACCR to support power outage contingency planning. Since the conductor can carry double the capacity of existing lines, some lines can therefore be reserved as ‘spare’ to help continuity of service should the other lines fail.

Tests carried out by the US Department of Energy at its Oak Ridge National Laboratory showed that 3M ACCR retains its integrity after exposure to temperatures even higher than the rated continuous operating temperature of 210 à‚°C and the emergency operating temperature of 240 à‚°C. The core has the strength and stiffness of steel at half its weight, but with higher conductivity.

3M ACCR differs from traditional steel core cables in its use of high-performance, aluminium-based composite core wires. Each core wire contains many thousands of very high-strength aluminium oxide fibres. The ceramic fibres are continuously oriented in the direction of the wire and are fully embedded within high-purity aluminium. The wire’s mechanical and physical properties far superior to those of aluminium and steel.

Marigold launches chemical permeation chart for disposable gloves

Hand protection expert Marigold Industrial has created what is believed to be the first ever Chemical Permeation Chart for disposable gloves.

Click here to enlarge image

The new chart is an essential reference tool for anyone working with or responsibility for selecting hand protection for people working with chemicals who need to know what levels of protection disposable gloves will offer.

Ideally suited for those working in sectors such as the automotive, engineering, repair and maintenance industries the new guide provides essential information on what levels of contact time protection the range of Marigold Industrial disposable gloves provide against 96 common workplace chemicals. The easy-to-follow chart adopts a number rating from 0 to 6 to highlight specific glove permeation performance against the listed chemicals.

A glove with a score of 6 provides permeation protection of over 8 hours whilst a glove with a score of 0 provides protection of less than 10 minutes and is therefore inappropriate for use with a particular chemical. Users can also cross-reference official chemical names with their common alternative names.

“We are delighted to be able to launch our new Disposable Gloves – Chemical Permeation Chart, which provides essential performance data for all of our chemical resistant gloves.

“This type of information is essential in determining which product provides the very best protection against a wide range of chemicals and is an essential tool for anyone with health and safety responsibility, to minimise the risk of the protective performance of the glove being compromised and putting the wearer in potential harms way.

“The new chart effectively spells out clearly and simply not only how long you can safely use our gloves with a particular chemical but which gloves provide the highest levels of protection, therefore making decision making process a lot easier,” said Marigold Industrial UK Country Manager John Thorne.

Permeation is the process by which a chemical can pass through a protective barrier à‚— ie a glove à‚— without going through visible openings. Molecules of a specific chemical enter the glove material and effectively wriggle through the compound à‚— with the glove material often appearing unchanged to the human eye despite the fact its protection has been compromised.

Ventyx picked to optimize nuclear, coal operations at EPZ’s Borselle

Ventyx has licensed an integrated work and asset management solution to utility EPZ to manage the operations of its nuclear and coal fired generation plants at Borssele, the Netherlands.

EPZ provides a total of six per cent of electrical energy output in the Netherlands. At one point scheduled to close in 2003, the nuclear plant was licensed to run until 2034 after proving it could be operated safely and reliably.

In order to ensure the continued safety and reliability of the plant, EPZ decided to implement new asset and plant operations management systems. An integrated solution from Ventyx was selected after a competitive bid and is being implemented across both nuclear and coal fired assets.

EPZ is implementing an integrated asset and plant operations management software solution at Borssele, incorporating the Ventyx Asset Suite software and the company’s Shift Operations Management (eSOMS) Suite. Asset Suite is Ventyx’s comprehensive enterprise asset management (EAM) solution for managing both equipment and infrastructure.

eSOMS is a mission-critical plant operations management application suite which helps users ensure the safe, efficient and reliable operation and maintenance of their facility assets.

Delivered as a standard integrated solution offering, the best-of-breed software will allow EPZ to standardize and streamline work processes across both maintenance and plant operations staff, as well as ensure optimal performance of generation assets through increased availability, optimized spare parts inventory and improved reliability.

“As the lone nuclear energy producer in the Netherlands, EPZ had to do their due diligence to ensure they selected the best solution available to manage their generation operations,” said Ventyx President and COO Steve Carpenter.

“We are pleased and grateful to EPZ for selecting our software to help them continue their long history of providing safe and reliable power to the people of The Netherlands.

“Our Asset Suite solution continues to be the dominant asset management system for power generation in Europe.”

Differential pressure transmitter ideal for level, flow measurements

A range of smart differential pressure transmitters for process industry applications has been launched, which can be used for level measurement of closed, pressurised tanks, pump and filter control, or for closed pipe flow measurement in conjunction with an orifice plate, Venturi or nozzle.

Click here to enlarge image

The XMD range from Impress Sensors & Systems Ltd is ideal for flow applications due to the device’s ability to switch the output from a standard linear output to a square root extraction where flow rate can be output. The XMD has a differential pressure range from 75mbar up to 2 bar and with a static over-pressure capable of 130 bar line pressures. The calibrated pressure range can also be turned down 10:1 times, which means that a 75mbar range can give a full scale output at 7.5mbar, whilst still maintaining the 130 bar line pressure. A 5:1 turn down ratio maintains the accuracy of the transmitter, which is à‚±0.1 per cent FSO.

Outputs available are 4-20mA as standard with the option of having HART communication. If this option is selected, the XMD is ATEX-approved as standard. The device is intrinsically safe for Zone 0/1 and an Ex d version is available with a flameproof enclosure for Zone 1 applications.

The XMD range is designed for harsh process manufacturing environments and so the electrical enclosure is a two-chamber aluminium die cast, powder coated with the option to include an integrated smart display.

As Sam Drury, Sales & Marketing Director at Impress Sensors & Systems comments: “The integrated display enables the user to programme the device, including electronic damping of the signal, offset adjustment [of up to 90 per cent of full scale] and a turndown ratio of 10 to 1. The two-chamber aluminium die cast housing is prepared for chemical seals to extend the application possibilities even further.”

The optional display is an LCD with a visible range of 32.5mm x 22.5mm. There’s also a textual display and a 52-segment bar graph that runs along the bottom of the display for easy interpretation of the output from the device. Even with this display option, the XMD is still rated to IP67.

Roxtec to supply Greater Gabbard windfarm with cable seals

UK based international safety seal giant Roxtec has signed a major deal to supply the world’s largest offshore wind farm in the North Sea.

Swedish owned Roxtec will supply a range of cable seals to the Greater Gabbard wind farm off the Suffolk coast currently being developed by Scottish and Southern Energy and RWE npower renewables. Construction is under way and the project is due for completion in 2012.

Roxtec’s UK Managing Director Graham O’Hare said its cable transit seals are being used in all 140 of the 3.6 MW wind turbines which will power around 530 000 homes.

“This is an absolutely terrific contract for Roxtec to land,” he said. “The highly specialised nature of the contract means we have had to design bespoke cable transit seals able to withstand the harsh offshore environment. The deal really showcases the very best of Roxtec’s problem solving design mentality. In total 10 different applications are being used on the project specifically sealing the cabling within the wind turbines from fire, water and blast.”

Mr O’Hare said Roxtec has extensive experience in the wind industry having been used in almost every offshore wind farm in Europe. “The cable transit seals will be sealing cables and used as part of the retention system areas,” he said. “We have produced seals for the generator system, the switch room, the converter, the tower, the nacelle, the transition pieces and the control cabinets.”

How about considering infusion with nidaplast composites?

Extruded polypropylene honeycomb inventor and specialist nidaplast composites makes infusion easier and less expensive with a customizable, ready-to-use product called ROVIpan.

Click here to enlarge image

With ROVIpan, nidaplast composites makes infusion easier at lower cost. This new product combines two materials: 1) an environment-friendly polypropylene honeycomb core (nidaplast 8RI), with a nonwoven polyester surface that is ideal for impregnating with resin and enabling resin flow, and 2) glass-fibre skins with integrated flow medium (Chomarat’s Roviflow). And what are the advantages of ROVIpan?

According to Luc Nuttens, development engineer at nidaplast composites, it is an “all-in-one, productivity-boosting material that is ready to use, easy to handle, and suitable for manufacturing large sandwich parts in 5-40-millimetre thicknesses.”

It is also very cost-effective, for several reasons: the nature of the honeycomb structural core, and the reduced labour requirement, which in turn reduces the moulding cycle.

Thanks to its many advantages, the ROVIpan solution enables manufacturers to extend the use of infusion to new sectors. The solution is perfectly adapted to the industrial production of large panels.

It meets environmental standards and improves working conditions by reducing VOC emissions. It also enables cost reductions through more optimized use of the materials, with lower resin consumption for a better-quality composite, offering higher glass contents, greater reproducibility and improved surface finish.

To top off its offer, nidaplast composites proposes a new panel-cutting service using its nida-kit concept. Nidaplast addresses manufacturers who want to increase their productivity and profitability, helping them to reduce raw materials waste and optimize production organization.

ROVIpan meets the requirements for low weight, high strength and ecodesign, which are all essential for wind energy applications. It is the latest in a broad range of nidaplast products, and its properties are eminently suitable for wind turbine nacelle design. Used as structural core material, nidaplast 8RI honeycombs are more cost-effective and environment friendly than one-piece-moulded structures, because they allow smaller amounts of glass fibre and resin.

Recyclable polypropylene has excellent mechanical and acoustic properties, which makes nidaplast 8RI the ideal core material for the wind energy market. The cell geometry of the polypropylene honeycomb structure itself also confers very good vibration damping and acoustic insulation properties.
