Engineering....Lets just do more with less.
Here we go again, the local press here recently reported that the University of WA engineering faculty is proposing to cut staff numbers to cut costs. Of course the university has stated..."the changes would have no effect on the quality or number of students graduating from the faculty" ....oh really! Here in Australia our government is spending $4 billion plus on a National Broadband Network which has never been subject to a business plan but our universities and educational facilities are starved of funds. How about some real investment and forward looking investment in our most important asset - namely our young? Unfortunately it will not happen because it does not win votes among the masses who are looking forward to downloading more movies and TV on demand. What a joke! Australia is so fortunate that we can mine our resources without value adding to them and we are really good at having thousands of earthworkers to achieve this. Who needs engineering and a highly educated workforce?
Food for thought, what do you think?
Finally there are some "real" Instrumentation Courses out there, the Engineering Institute of Technology offers on line engineering Diplomas and Certificates (Masters Degrees accreditation pending) in Industrial Automation, Instrumentation and Process Control and have just added a new Advanced Diploma of Electrical and Instrumentation (E &I) Engineering for Oil and Gas Facilities.

|Now this is "Smart" - ‘Smart’ Contact Lens with Embedded Wireless Sensor Promises Earlier Diagnosis and Optimized Treatment of Glaucoma - MEMS (Micro-Electro-Mechanical Systems), has announced that it will develop and supply a wireless MEMS sensor that acts as a transducer, antenna and mechanical support for additional read-out electronics in a breakthrough platform developed by Swiss company Sensimed AG. This solution will enable better management of glaucoma patients via earlier diagnosis and treatment that is optimally tailored to the individual patient. Known as the SENSIMED Triggerfish®, the solution is based on a “smart” contact lens that uses a tiny embedded strain gauge to monitor the curvature of the eye over a period of, typically, 24 hours, providing valuable disease management data that is not currently obtainable using conventional ophthalmic equipment.||
Mounting Evidence that Carbon Nanotubes may be the New Asbestos - Carbon nanotubes – thin, hollow cylinders made of carbon atoms – look very much like asbestos. In 2004, the United Kingdom’s Royal Society and risk specialists at the world’s second largest reinsurance agent Swiss Re warned that once in our lungs, nanotubes may also behave like asbestos. Since then, a series of experiments have demonstrated that when introduced into the lungs of rodents, carbon nanotubes cause inflammation, granuloma development, fibrosis, artery ‘plaque’ responsible for heart attacks and DNA damage. Two independent studies have shown that carbon nanotubes can also cause the onset of mesothelioma – cancer previously thought to be only associated with asbestos exposure. Unfortunately, despite mounting evidence of the asbestos-like dangers of carbon nanotubes, their commercial use is also growing rapidly – in sports goods, car and aeroplane parts, reinforced plastics and electronics- from Friends of the Earth Australia.

Reading HART Data into Non-HART Systems - Many HART products are able to perform more than one measurement or output function (e.g., make multiple process measurements, calculate process information, and provide positioner feedback information). All of this information can be easily accessed digitally. However, existing controllers or interface equipment may not have the ability to read digital HART data. Products are available that can read HART digital signals and convert them to analog (4-20mA) and alarm trip (contact closure) information, which enables any traditional analog control system to take full advantage of the benefits of HART- communicating devices. From our valued sponsor Moore Industries-Pacific, Inc.
ICEweb's HART page has been reworked to include numerous new technical links.

Open Asset Management with FDT: the Core of a ‘Smart’ Process Plant - Field Device Type (FDT) technology remains one of the automation industry’s best-kept secrets. In spite of this, it is rapidly gaining market acceptance by simplifying the digital communication between a plant’s field devices and its control environment. It is at the heart of a ‘smart’ plant’s IT infrastructure and can deliver major cost savings to the plant’s operations - from www.processonline.com.au .
Control Valve Experience with FF Technology - at major Chinese petrochemical plant CSPC, a joint venture between the China National Offshore Oil Corporation (CNOOC) and Shell, is one of the largest petrochemical projects launched in the world in recent years. When production started in Nanhai early in 2006, the project was the biggest installation utilizing Foundation Fieldbus (FF) technology in process control and field instrumentation. The main reason for FF technology to be selected for the CSPC Nanhai project was its ability to provide a proactive approach to instrument maintenance. This is due to the fact that FF allows much more data to be transferred between field instruments and the host system compared with HART technology, for example. FF devices transmit information about an instrument’s condition before it actually needs maintenance or, obviously, when an instrument has an actual problem, as well as providing detailed diagnostic information about the nature of the problem. CSPC’s petrochemical plant is an early and successful example of adaptation to a new technology. CSPC uses diagnostic information from the intelligent FF valve controllers daily - from our sponsor Metso Automation
The HART® Communication Foundation has announced new Improvements to the WirelessHART® Test System - Wireless Test System v1.4 and Wi-Analys Software v1.3.

Fieldbus: Commissioning with Advanced Diagnostic Tools - Modern day fieldbus diagnostic tools – such as the Advanced Diagnostic Module for the FieldConnex® Power Hub – bring transparency to the fieldbus physical layer and communication. The module performs measurements such as supply voltage, load current, signal level, line noise or jitter. The module listens to the communication and distinguishes between segment and device information. Clear and concise displays within the Diagnostic Manager show readouts to the user – this brings transparency to a plant condition that seems ambiguous.
Monitoring the Fieldbus Physical Layer - Commissioning the fieldbus with advanced diagnostic tools - What was unthinkable for point-to-point wiring, is affordable for the fieldbus: the new Advanced Diagnostic Module from Pepperl+Fuchs offers the measurement and monitoring of the physical fieldbus structure from the control station. Designed as a plug-in card for the modular power supply system Power Hub, the module gathers all the measurements of the fieldbus physical layer for all fieldbus segments and combines them at a single maintenance workstation online and in realtime. The fieldbus diagnosis provides transparency, and the measurability of the actually transferred signals gives installers and operators of process systems a more complete picture of the behaviour of the fieldbus. This allows for otherwise often inexplicable behaviour to be analysed with precision. You can also measure and verify the reserve power available on the fieldbus.
Fieldbus Foundation Announces Final Release of ITK 6.0 - The Fieldbus Foundation has announced the final release of its H1 Interoperability Test Kit (ITK) 6.0. This powerful test tool, which tests the functionality of a fieldbus device and its conformity with the Foundation function block and transducer block specifications, is available to members holding an active maintenance agreement. The H1 ITK 6.0 has been updated to test for new, required field diagnostics capabilities, which standardize how all fieldbus devices communicate their diagnostic data to the process control and asset management systems—regardless of the vendor. The test kit also employs an all-new, intuitive user interface.

Analysers - ICEwebs Analyser pages cover many types of analysers plus their associated sample systems.
Online Moisture Analysis in Materials Handling - Graeme McGown - Moisture analysis during materials handling and processing presents a number of challenges that can be solved with appropriate use of online techniques - from Intalysis and www.processonline.com.au
CSIRO Develops New Oil Detection Technique - CSIRO scientists have developed a revolutionary technique for the rapid on-site detection and quantification of petroleum hydrocarbons (commonly derived from crude oil) in soil, silt, sediment, or rock. Developed in collaboration with waste technology specialist, Ziltek Pty Ltd, the technique means that the presence of petroleum hydrocarbons can now be quantified simply by using a hand-held infrared spectrometer to take readings at the site of interest, without the need to take samples or perform any kind of processing.
Ensuring an Accurate Result in an Analytical Instrumentation System - Doug Nordstrom and Tony Waters - In many analytical instrumentation systems, the analyser does not provide an absolute measurement. Rather, it provides a relative response based on settings established during calibration, which is a critical process subject to significant error. To calibrate an analyser, a calibration fluid of known contents and quantities is passed through the analyser, producing measurements of component concentration. If these measurements are not consistent with the known quantities in the calibration fluid, the analyser is adjusted accordingly. Later, when process samples are analysed, the accuracy of the analyser’s reading will depend on the accuracy of the calibration process. It is therefore, imperative, that we understand how error or contamination can be introduced through calibration; when calibration can — and cannot — address a perceived performance issue with the analyser; how atmospheric pressure or temperature fluctuations can undo the work of calibration; and when and when not to calibrate - thanks to Swagelok and www.pacetoday.com.au
How to use a Regulator to Reduce Time Delay in an Analytical System - Doug Nordstrom and Mike Adkins - Process measurements are instantaneous but analyser responses never are. From the tap to the analyser, there is always a time delay. Unfortunately, this delay is often underestimated or misunderstood - from www.inmotiononline.com.au
Continuous Emission Monitoring - C B Daw - The requirements for continuous emission monitors has changed significantly over the last ten years. This has been brought about by the increase in use of flue gas treatment systems, reducing the levels of pollutant to be monitored, and Environmental Agencies worldwide requiring smaller processes to be monitored. The Environmental Agencies have insisted that continuous emission monitors meet more stringent specifications, including repeatability and the capability to be fully challenged to demonstrate compliance. In addition, reporting regimes necessitate maximum availability. Pressure from the market place also requires the modern CEM system to have a low cost of ownership, which, in effect, means that high reliability must be a design criteria. There are many applications for continuous emission monitors, covering a variety of industries. The specification of the CEM system will depend on, not only the type of process, but also the pollutant gases that are required to be measured. The choice of the CEM system will depend on many factors, including the monitoring and reporting requirements of the local Environmental Authority - from Group Instrumentation. See more papers on this subject in ICEweb's Continuous Emission Monitoring page.
Oxygen Measurement for Combustion Optimisation - Combustion optimisation for boilers and other combustion processes has long been an important issue with increasing fuel prices. There are many end users in Australia with fuel bills in excess of one million dollars. With typical costs of combustion optimisation systems, and possible fuel savings in excess of 5%, pay-back periods can be very short. This economy is based primarily on the measurement of oxygen in the flue gas - from www.processonline.com.au
The ABB Guide to Fast pH Measurement - Used for a host of applications across a variety of industries, getting the best from pH equipment requires consideration of a range of factors to achieve optimum efficiency and cost effectiveness.
Accurate Liquid Phase Density on Aerated Liquid - Dan Gysling and Doug Loose - Density is one of the most widely used composition-based measurements in industrial process control. However, it is well recognized that the presence of small, but unknown levels of entrained gases can mask the density of the non-aerated component of a process mixture, resulting in an inaccurate determination of process fluid density - from Sonartrac

NeSSI’s Success should be a Lock - Mark Rosenzweig - The New Sampling/Sensor Initiative or NeSSI that replaces tubing, fittings and other hardware in a sampling system with miniature modular components makes sense. Enhancements now in the works should assure its success.
Intrinsically Safe NeSSI Nears - An emerging bus standard promises to spur application in hazardous environments - Rick Ales - The New Sampling/Sensor Initiative (NeSSI) has provided the basis for modular miniaturized process sampling systems that offer ease of assembly and flexibility while cutting cost of ownership. Not surprisingly, plant acceptance of such NeSSI systems is growing. A group of analyser specialists now is working to enable NeSSI to be used in hazardous environments. They envision an analytical system with smart transducers that would be capable of being field mounted at the sample point in a potentially explosive atmosphere and would be easily integrated into the analyser control system - Thanks to chemicalprocessing.com.
Smaller, Smarter Systems Streamline Sampling - Mike Spear - An emerging miniaturized, modular approach for sampling systems provides substantial savings in both capital and operating costs - Faced with ever increasing competition on price for their products, chemical companies are constantly searching for ways to cut costs across their operations. This, in turn, puts persistent pressure on engineers to reduce both capital and operating expenditures — without compromising their plants’ reliability and performance in any way. Easier said than done, perhaps, but this is precisely what a new approach to the task of delivering process samples to analysers actually delivers, claim its proponents. Since coming into being some five years ago, the New Sampling/Sensor Initiative (NeSSI) has become the driving force behind the move to modularize and miniaturize process sampling systems. Now operating under the sponsorship and umbrella of the Centre for Process Analytical Chemistry (CPAC) at the University of Washington, Seattle, NeSSI first surfaced as an ad hoc group of people drawn both from equipment manufacturers, keen to adopt the modular approach, and operating companies prepared to put the vendors’ prototype products to the test on their plants - Thanks to chemicalprocessing.com.
In the USA, the Bureau of Ocean Energy (formerly Minerals Management Service) has recently issued a Final Rule in the US Federal Register that sets limits on the flaring or venting of natural gas. These regulations state that all flare and gas vent emissions have to be measured to within ± 5% uncertainty and, depending on production levels, will have to be in place by the start of December 2010 at the latest.
Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a microminiaturized device that can make complex viscosity measurements — critical data for a wide variety of fields dealing with things that have to flow — on sample sizes as small as a few nanoliters.

Performance Monitoring of an Offshore Gas Compressor - Lauren Neal - Offshore equipment is monitored to prevent any unnecessary downtime but unfortunately for some, such as compressors, there is a lack of effective monitoring. This is critical because, along with the gas turbine, it is the highest cost offshore item in terms of capital and operational expenditure but is the least technically and operationally understood. Monitoring an important item of equipment such as a compressor is essential as it can be difficult to obtain replacement parts or units if a failure was to occur. Adopting a preventative maintenance strategy with regard to compressor monitoring can prevent downtime costs from arising before failures occur or shutdown is mandatory. A common cause of compressor downtime is a fault with the bearings. This initiated an investigation to analyse the bearings of an offshore gas compressor, using statistical modelling techniques, with the view of predicting failures and therefore reducing unplanned downtime - from Matrikon
The DCS as Enabling Platform -Andy M Smith and Martin Davis - Justifying the decision to invest in a new or upgraded control system is always going to be difficult. This paper explains how a more compelling business case can be made by regarding the modern Distributed Control System (DCS) as an enabling platform with a proven ability to reduce the cost of future projects by orders of magnitude. Also detailed is a replacement project that used such a benefit case, of the inherent capability of a modern DCS, to gain a business sanction - from Emerson Process Management.

Fuzzy Control System - Fuzzy logic is widely used in machine control. The term itself inspires a certain scepticism, sounding equivalent to "half-baked logic" or "bogus logic", but the "fuzzy" part does not refer to a lack of rigour in the method, rather to the fact that the logic involved can deal with fuzzy concepts—concepts that cannot be expressed as "true" or "false" but rather as "partially true". Although genetic algorithms and neural networks can perform just as well as fuzzy logic in many cases , fuzzy logic has the advantage that the solution to the problem can be cast in terms that human operators can understand, so that their experience can be used in the design of the controller. This makes it easier to mechanize tasks that are already successfully performed by humans - from Wikipedia, the free encyclopedia.The MatrikonOPC's webcast "OPC Specifications – Part 4 – OPC UA” provides attendees with an overview to the new OPC Unified Architecture Specification.

ESD Valves - Shutdown and Blowdown - This comprehensive page includes technical and design information on Emergency Shutdown Valves, Shutdown Valves, Blowdown Valves, Actuators, Fire Safe Actuators, ESD Valve Fire Shelter and Partial Stroke Testing.
Shutdown and Blowdown ESD Valve page has been extensively upgraded thanks to
our sponsor Metso
Automation. New technical links include;
- Atmospheric Distillation ESD Valves - Atmospheric distillation is the first major process in a refinery. All crude oil entering the refinery, after desalting, passes through the atmospheric distillation column on it’s way to further processing in down stream process units. If there is a shut down of the atmospheric distillation column it means that the entire refinery is essentially shut down. The ESD valves are located at the bottom of the atmospheric distillation column and are typically arranged as two valves in parallel piping. The fluid passing through the valves is referred to as heavy bottoms. This fluid is the heaviest cut of a hydrocarbon attainable by atmospheric distillation. The heavy bottoms pass through the ESD valves on their way to the vacuum distillation column for further processing. The ESD valves are used in the normally open condition and are expected to function reliably throughout long process runs, typically four (4) to five (5) years between shut downs.
- Oil Refinery and Other Units Processing Hydrocarbons - ESD valves with High Integrity Level - There are fire and explosion risks in the units processing flammable hydrocarbons in case the fluid comes in contact with the atmosphere. If there are high- and low-pressure sections in the plants like e.g. in refinery HDS (hydro desulphurisation) units, the low-pressure side has to be protected against high pressure in case of control failure. Traditionally the number of emergency shut-off valves (ESD) in the process lines in a refinery is not very high. With Neles ValvGuard’s partial stroke testing functionality the ESD valves are automatically diagnosed for their operability while the plant is in operation. With this technology general plant safety can be improved in a cost effective way.
- Reliable ESD Valves in Tower Bottom Lines in Heavy Oil Units - Besides fired heaters, the distillation tower bottom areas are the most fire-risky places in a refinery. When the question is of residual oils, high oil temperature, coke formation, sulphur corrosion and possible particles in the oil make the conditions even more severe. Neles metal-seated ball valve with its constructional features and the Neles ValvGuard, partial stroke testing system, used to keep the valves under continuous watch are helping to minimize the fire risks in these areas.
- What You Need To Know About Safety Instrumented Systems (SIS) and Partial-Stroke Testing of ESD Valves - A useful document providing an overview of SIS and Partial stroke testing.
- The Value of Safety Valves - Juha Yli -Petä ys - Safety valves are the most important components in the safety loop (sensor, safety logic and final element), because most of the problems that occur are related to the functionality of the final element. It is important to remember that these elements are moving mechanical devices, which operate in very difficult environmental conditions. This makes the need for regular valve testing and for testing while the process is running absolutely essential.
- Increased Reliability and Safety at Czech Refinery through Partnership in Valve Maintenance - Karel Dvorak and Niko Aunio- In the past, Česká Rafinérská’s strategy has been to carry out turnarounds every four years. This was the first time that the interval was extended to 5 years. After 9 years of operation, some problems were expected, however, on this occasion Česká Rafinérská’s approach was different from that adopted for the previous turnaround. The control valve scope was reduced and the on/off valve scope increased to include overhaul testing based on the SIL classifications. The Metso field survey and Neles ND9000 diagnostics formed the basis for the valve turnaround planning.
ABB has announced that it will collaborate with Dresser Masoneilan®, on an integrated process to monitor, test and manage emergency shutdown valves (ESDV) during all operational conditions, from normal plant operations to abnormal situations. These valves are crucial process elements for the oil, gas and petrochemical industries, as well as many other industrial processes.

Behind the Scenes of Steam Flow Measurement - Jesse Yoder - Steam, or vaporized water, is an important part of our daily lives. It is easy enough to experience steam; simply boiling water will produce it. But steam has equally important uses as a source of power for ships, in paper production, and for cooling and heating buildings. Probably the most important use of steam is as a source of power in electricity production. Steam is difficult to measure accurately, mainly because of its sensitivity to changes in temperature and pressure. Steam is often classified into three types, which reflect the different pressure and temperature conditions that steam is subject to - from ISA and InTech.
Using Meters to Measure Steam Flow - Jesse Yoder - When people hear about fluid measurement, they usually think of checking either liquid or gas flow. This belief is natural, since about 90% of fluid measurements are for these two applications. In a worldwide survey of flowmeter users, 68% measured liquids, 22% gas, and only 10% steam. While 10% may not seem like a large percentage, it represents a significant number of measurements. Many companies measure steam for purposes of internal custody transfer and for utility applications in power generation and chemical plants - from www.flowresearch.com and Automation Research Corp.
Understanding Steam Flow Meters - Steam flow measurement is important in this context because steam is widely used as a source of power in the production of electricity. As the costs of energy rise, many companies are looking to increase efficiencies in their energy and power generation. As a result, more attention is being paid to steam flow measurement - Thanks to Chemical Professionals.

Road Tanker Earthing - The loading and unloading of road tankers with flammable and combustible products, presents one of the most serious fire and explosion risks for site operations within the hazardous process industries. A study conducted by the API in 1967 identified static discharges as being responsible for over 60 incidents in road tanker loading operations and demonstrates just how long this potential threat has been acknowledged. The natural presence of static electricity in product transfer operations, combined with its associated ignition hazards, ensures that regulators take static control precautions for road tankers very seriously - from Newson Gale.

Pressure Gauge Selection Strategy - 7 Key Considerations to Ensure Application Success - Chikezie Nwaoha - In order to maintain the efficiency of pressure gauges in general (bourdon tube, bellows, helix, etc.), a thorough selection strategy should be employed. As such, end-users would be wise to carefully consider pressure gauge selection, as failure to select the correct pressure gauge for an application can result in significant plant downtime. Further, in a worst-case scenario, an improperly specified pressure gauge can fail to measure pressure during an overpressure event, compromising plant safety and potentially resulting in costly damages. In order to improve pressure gauge operating efficiency and service life, there are seven basic selection criteria end-users should consider - from www.flowcontrolnetwork.com

Following the "heads up" in the last issue of ICEnews Byres Security Inc. have advised that since mid-July their team has been working hard on determining exactly what operators of SCADA and industrial control systems can do to protect their facilities from infection from the Stuxnet worm. This worm is both complex and dangerous to all control systems. As a result, they have updated their Stuxnet White Paper “Analysis of the Siemens WinCC / PCS7 ‘Stuxnet’ Malware for Industrial Control System Professionals”. To obtain this white paper you must register on the Tofino Security website. In the latest version they have created a detailed list of Prevention/Mitigation techniques you can use to protect computers running both supported Windows operating systems and older unsupported systems that cannot be patched. These mitigations are recommended for all control systems, regardless of whether a Siemens product is used or not. In addition their blog, Practical SCADA Security, is featuring a companion document to this White Paper, the Stuxnet Mitigation Matrix. This matrix shows the multiple actions required to counteract the numerous Stuxnet vulnerabilities in the Windows operating system and the Siemens product line. It is a practical guide to reducing your exposure to the malware.

It is widely used to interconnect Human Machine Interface (HMI) workstations, data historians and other hosts on the control network with enterprise databases, Enterprise Resource Planning (ERP) systems and other business-oriented software. Unfortunately, securely deploying OPC Classic has proven to be a challenge. This white paper describes two independent techniques for ensuring strong security in systems using OPC Classic technology. This first creates zone-based defences using OPC-aware firewalls. The second takes advantages of improvement in the Windows operating system to managing OPC accounts and permissions. Both security techniques are available and proven for use in today’s control systems.

How New Low-Power Solenoid Valve Technology Changes The Game - Fabio Okada, Jack Haller, and Manny Arceo - Process plants worldwide often place considerable reliance on low-power solenoid valves. They are used as pilot valves to open and close larger ball or butterfly valves, or on control valves (installed between positioner and actuator) for fail-safe air release if there’s a loss of power. They work by pressurizing or depressurizing associated actuators. A new generation of even lower-power valves is now changing the rules of the power consumption game. These products are of interest to designers working for original equipment manufacturers (OEMs) and valve assemblers, as well as for end-user engineers anyone who specifies solenoid valves for projects in refining, upstream oil and gas, chemicals, pharmaceuticals and life sciences, food and beverage, and power. This report taps the expertise of manufacturers at the forefront of low-power solenoid valve technology. It shows how innovation is offering new possibilities — and challenges — via topics such as integrated solutions, clogging and other reliability issues, usefulness in point to point and bus networks, other cost savings, remote applications, and relevant industry standards. Finally, it suggests which characteristics buyers should seek out in selecting the newest — and most consistently dependable — low-power valve technologies.
How New Lead-Free Regulations Will Impact Your Selection Of Potable Water Valves - Paola Gutierrez - Recent legislation in several states has tightened regulation of lead content in the components of potable (drinkable) water treatment systems. Other states may well be considering similar moves. This pace of regulation seems unlikely to slacken. The message from regulators is clear: Get the lead out. However, what options are open to construction end users and original equipment manufacturers (OEMs) of these systems? Construction managers don’t make the equipment they install. And OEMs often assemble most of their systems from already manufactured components. Of compliant components they can specify, which currently meet their requirements for price, reliability, and performance? This report examines the choices facing specifiers and purchasers of small solenoid valves for potable water systems. It weighs the advantage and disadvantages of brass, plastic, and stainless steel designs. Finally, it suggests the solutions that smart planners should consider for current and future use.
Functional Safety Solutions for the Process Control Industry - ASCO solenoid pilot valves are an integral part of the final control element for any safety instrumented system (SIS) or critical application. ASCO offers 3 solenoid pilot valve solutions that are widely used in the process control industry; individual 3-way pilot valves, manual reset valves, and redundant pilot valve systems. Each of these solutions are proven in use as a pilot valve in critical applications and in safety instrumented systems.

Selecting Transmitters for Safety Instrumented Systems - Stephen R. Brown and Mark Menezes - Users design safety systems to mitigate the risk of identified process hazards within tolerable levels, using application-specific risk models, defined user inspection schedules, and safety data for the devices under consideration. Some suppliers provide safety data for their devices. However, supplier data, even when validated by a third party, reflects laboratory results, and can be an order of magnitude too aggressive for field devices. “Proven-in-use” data includes real-world failure causes; however it tends to be conservative, since it must cover the whole range of the category, from 20-year-old pneumatics to the latest smart technology. Moreover, proven-in-use data is often aggregated for a given technology: for example, “pressure transmitter = dangerous failure rate of once in 50 years”. This aggregate data often does not isolate failure causes, so it does not allow users to take credit for improvements in technology or user practices intended to minimize the impact of specific failures. The net result to the user can be over design, over-testing, increased spurious trips and needless capital expenditures - from IDC
Integrating Control and Safety – Where to Draw the Line? - Robin McCrea-Steele - New digital technology now makes it feasible to integrate process control and safety instrumented functions within a common automation infrastructure. While this can provide productivity and asset management benefits, if not done correctly, it can also compromise the safety and security of an industrial operation. Cyber-security and sabotage vulnerability further accentuate the need for securing the Safety Instrumented System (SIS) - From the Safety Users Group.
Warning on Air Receivers - WorkSafe Victoria has released new guidance focussing on the safety risks associated with air receivers - a type of pressure vessel used to store compressed air for large demands greater than a compressor's capacity. WorkSafe director Ross Pilkington says air receivers have the potential to seriously hurt people and damage property if they were not properly installed or maintained. There have been serious incidents involving air receivers exploding in Victorian workplaces - and it has only been good luck that no one was working near them at the time. Employers with air receivers must ensure they are properly maintained to reduce the risk of explosion or fire. The handbook 'Working safely with air receivers' is aimed at improving awareness of the risks associated with air receivers, and explaining ways to eliminate and reduce those risks.

Replacement of SIS Logic Solvers Whilst the Process Remains Operational - Clive Timms - With increasing global demand for oil and gas driving prices higher and higher, the focus of oil and gas producers is to maintain and maximise production from every available facility. Older unreliable facilities are being upgraded and this often includes the replacement of Safety Instrumented Systems (SIS) such as emergency shutdown (ESD) systems, process shutdown (PSD) systems, Emergency Depressurisation (EDP) systems and fire and gas (F&G) systems due to obsolescence or reliability issues. Traditionally, the replacement of such safety critical systems is undertaken during a plant shutdown opportunity to ensure that process integrity was maintained and the replacement systems could be fully commissioned and validated without the presence of the process hazards. However, in this era of high oil and gas demand we are now seeing more and more SIS replacement projects being undertaken whilst the process is still fully operational, and this can lead to potential compromises during commissioning and validation of functionality - from C&C Technical Support Services and silsupport.com
IEC 61511 – An Aid to COMAH and Safety Case Regulations Compliance - CliveTimms - The paper focuses on the relationship between hazards and Safety Instrumented Systems (SIS) that automatically shut down processes operations, when an abnormal situation is encountered, to prevent a hazardous event or mitigate the consequences of a hazardous event if it occurs (see section - Safety Instrumented Systems). Thus a SIS will represent an integral part of an SMS to reduce the risk of major accident hazards or mitigate the consequences - from Asset Integrity Management Ltd.
A new Guidance Note in NOPSA’s series to assist Operators of offshore petroleum facilitieswith safety case preparation is now available on their website. The ALARP (As Low As Reasonably Practicable) Guidance Note provides information to assist operators with the process of describing how they have reduced risks to a level that is As Low As Reasonably Practicable, which is an integral part of the formal safety assessment description within a safety case and central to meeting the Operators general duty under the OHS Law. The new Guidance Note explains ALARP principles in the context of the Australian offshore petroleum health and safety regime. The Guidance Note should be of particular use to those with responsibility for planning and developing facility Safety Cases, and those involved in Safety Case implementation, maintenance and ongoing risk management.
Don't Gamble with Control Safety and Reliability - Understand the benefits and limitations of safety instrumented systems - Arthur Zatarain - As a wise singer once crooned, you have to “know when to hold ’em and know when to fold ’em.” But Kenny “The Gambler” Rogers merely had to beat long-shot odds to win at his game. Outside the casino, designers of industrial control systems don’t have the luxury of being right only 51% of the time. For many manufacturing and process systems, a control system failure — even for a second — simply isn’t an option. Hence, it’s important that control systems deliver safe and reliable performance, even when things go wrong - from PlantServices.com.
Meridium has announced a new product solution, Hazards Analysis. Hazards analyses are conducted to uncover potentially hazardous situations in manufacturing and process plants and are used to document safeguards, make recommendations to modify safety processes, and add procedures to attain the desired safety level. The Hazards Analysis module provides a mechanism and standard methodology for conducting hazards and operability (HAZOP) and what-if analyses.

WirelessHart Signals a Change at Plants - Gareth Johnston and Alan Munns - Wireless technology is so much a part of our lives that we use words like "Blue Tooth" and "WiFi" systems with confidence and familiarity. So why has it taken so long for industry to take advantage of the benefits a wireless connection can offer? - from ABB
Enhancing Oilfield Operations through Wireless Technology -Ed Morrison - Advancement in directional drilling technology has changed the way oil and gas production companies design and manage well locations and associated well site automation. Multiple wells require multiple production tanks. Environmental concerns and increasing regulation over hydrocarbon fluids stored in remote tanks require production companies to redefine or find new ways of automating wellhead control to prevent tank spills. The next generation of wireless monitoring and control products provide sophisticated monitoring capabilities and fail safe networks to address these needs. Whether automating field locations with a single well, multiple wells or remote facilities, wireless monitoring and control systems offer many advantages over hard wired systems - from O&G and OleumTech Corporation.
Emerson Process Management has expanded the capabilities of its CSI 9420 Wireless Vibration Transmitter to deliver more detailed information for machinery analysis.
