How to Write an Outstanding Engineering Resume - This Blog from IDC's Steve Mackay gives some excellent tips on creating an Engineering Resume - I believe we have all had what we considered an excellent resume (cv) rejected at some time or other in our career. While I am not suggesting that you need to leave your current good job; it is good to keep in mind what is required and perhaps, in these uncertain times, to help a buddy who may need some support in writing his or her resume. This skill is vital whether you are an electrician or a chief engineer. If you do an Internet search for ‘resume or cv writing’, you will have thousands of links – all guaranteeing you a top job. This short note is to help you create a winning engineering cv with a business edge. Which I believe is vital to success.

5D ‘Superman Memory’ Crystal Could Lead to Unlimited Lifetime Data Storage - Using nanostructured glass, scientists at the University of Southampton have, for the first time, experimentally demonstrated the recording and retrieval processes of five dimensional digital data by femtosecond laser writing. The storage allows unprecedented parameters including 360 TB/disc data capacity, thermal stability up to 1000°C and practically unlimited lifetime. Coined as the ‘Superman’ memory crystal’, as the glass memory has been compared to the “memory crystals” used in the Superman films, the data is recorded via self-assembled nanostructures created in fused quartz, which is able to store vast quantities of data for over a million years. The information encoding is realised in five dimensions: the size and orientation in addition to the three dimensional position of these nanostructures.  

Schneider Electric Buying Invensys? - There has been speculation for a long time that the Invensys automaton business would be sold. Now Schneider Electric has made a 3.3 billion pound ($5 billion) takeover proposal for Invensys. This could ignite a bidding competition since it has been rumoured in the past that Emerson Electric, Siemens, ABB, and General Electric have had informal discussions with Invensys. Schneider has until August 8 to say whether it intends to make a firm offer or walk away under UK takeover rules - from Automation Weekly.

ICEbus - Information on any of the 26 different bus systems in use in the area of Instrumentation and Control.

Foundation Fieldbus, Fourth Edition - Ian Verhappen and Augusto Pereira

The fourth edition of Foundation Fieldbus significantly expands the subject matter of the earlier editions of this popular book not only to help you stay current with this evolving technology but to also enhance your understanding of Fieldbus. This edition provides in-depth coverage on Fieldbus communications and configuration, including calculation of macrocycle for Control-In-Field and in the Host system and how the different forms of communication on the H1 network work with each other to make Control-In-Field possible, including the use of these different methods to optimise network bandwidth.

Part of the field network evolutionary process includes a need to understand better how the changes in Electronic Device Description Language (EDDL), Field Device Tool (FDT), and Field Device Integration (FDI) will affect the way Fieldbus and other networks work together with asset management systems of the future, and your interaction with field devices.

More comprehensive step-by-step procedures are discussed for each stage of a typical FF installation: Inspection and electric commissioning to ensure cable integrity, H1 Network commissioning, configuration, and communications tests in the segments and the spurs. Several new photographs and explanations help emphasize the proper installation procedures so you can quickly identify and prevent potential problems when installing Fieldbus systems.

The contents of the entire book are then put to use with a full sample network design. The example is based on a typical simplified distillation tower and includes sample calculations/documentation-based.

The fourth edition explains Foundation Fieldbus in a convenient, easy-to-understand way, regardless of your level of experience; a novice wanting to learn what FF is all about or an experienced user looking for a few more tips and a single handy reference.

PROFIBUS Diagnostics Suite - New Version - Softing has announced the availability of a new software version of its innovative PROFIBUS Diagnostics Suite. The latest update includes novel diagnostic features to execute extensive tests on a PROFIBUS network. The PROFIBUS Tester 4 is able to simultaneously analyse the electrical signals and the data communication on an operating network eliminating the need for multiple components. In addition, the intuitive user-interface of the unit is designed to guide a novice down the correct path to solving a network problem. The instrument is galvanically isolated to prevent problems where two or more electric circuits communicate, but their grounds may be at different potentials. Without galvanic isolation a tester could introduce noise to the cable under test masking the actual cause of a network fault. It is an effective method of breaking ground loops by preventing unwanted current from flowing between two units sharing a ground conductor. Companies like Husky Injection Molding, Robert Bosch, and BMW rely on this tester from the commissioning to the maintenance phase of their automation networks. Today, many companies are replacing their existing set of diagnostic instruments and standardize on Softing’s state-of-the-art tool. Download the latest version of Softing’s PROFIBUS Diagnostics Suite V2.11 (under the “Downloads” tab) free-of-charge here

"Project Gemstone" To Make Fieldbus Experience Easier, More Application-Centered - The Fieldbus Foundation have announced a new technology development initiative-Project Gemstone-intended to make the digital fieldbus automation experience easier than conventional analog control systems in every conceivable way, from device setup to device replacement and daily maintenance practices. Encompassing a wide range of Foundation fieldbus development efforts, Project Gemstone covers many of the initiatives the Fieldbus Foundation is already working on today. This includes Foundation for Remote Operations Management (ROM), Field Device Integration (FDI) Cooperation, and ISA108 intelligent device management. Foundation for ROM technology allows users to integrate their WirelessHART, wired HART, ISA 100.11a devices, remote I/O, and Modbus communication into the Foundation fieldbus managed infrastructure. FDI is working towards a single device integration package that will provide all the benefits of Electronic Device Description Language (EDDL) and FDT/DTM technology. The ISA108 standards effort is defining recommended work processes for intelligent device management, regardless of communication protocol. The foundation's new usability team is also focusing on how to make fieldbus devices easier to specify, set up, configure and maintain.

Successful FOUNDATION for Remote Operations Management Field Demonstration Held In Brazil - The Fieldbus Foundation conducted the first live demonstration of its Foundation for Remote Operations Management (ROM) technology at the Petrobras research and development facility (Cenpes) in Rio de Janeiro, Brazil. Held on April 30, 2013, the demonstration was attended by Petrobras company executives and automation industry media from around the world. The first development of its kind integrating remote input/output (I/O), ISA 100.11a, WirelessHART®, wired HART, and Foundation fieldbus H1 protocols into a single, standard data management environment, Foundation for ROM extends the capabilities of Foundation fieldbus to wired and wireless devices installed in some of the world’s harshest and most remote locations. This open, non-proprietary solution provides a unified digital infrastructure for asset management in applications ranging from tank farms and terminals to pipelines, offshore platforms, and even original equipment manufacturer (OEM) skids.

The FDT Group's New White Paper FDT2 Specification Provides Enhanced Security and Improved Performance” is now available for download.  The paper examines many of the key benefits of the released FDT2 specification focusing on the enhancements in security and performance.  Several DTMs and Frame Applications based on the FDT2 specification have been released with many more in development.

Analysers

ICEweb's Analyser pages cover many types of analysers plus their associated sample systems.

On-Line Process Analyzers - Potential Uses and Applications – This document provides ideas for application of Precision Scientific process analyzers in petroleum refineries. The information is arranged by refining process. Included in this synopsis are applications which may be economically feasible in many refineries. The primary advantage to using on-line process analyzers in refining operations is the ability to control the product streams closer to specifications. Periodic analysis of the product streams leaving a particular unit can be used for both quality control and for control of the unit operation, in order to maximize the yield of high-value products. A dedicated process analyzer would be able to provide measurement results quicker and with better repeatability than laboratory analysis. This would allow for better control of heater loads, reflux, and the tracking of transients. Improved control would allow for greater yields of high value products by reducing the give-away needed to assure that all products meet specifications - from Expotechusa.  

Improving Analytics to Meet Process Industry Demands - Moving analyzers from the lab to a field-based shelter to the pipe will cut costs, reduce maintenance, and improve operations - Creating products from raw materials in pharmaceutical, petrochemical, and other process plants depends on intricate process systems executing numerous steps or unit operations. To ensure efficiency, quality, and safety, precise measurements must be taken during the various stages of production. These measurements have typically been made using instruments and analyzers. These devices supply information to plant personnel in control rooms and laboratories. Instruments are used to measure basic parameters, such as pressure, temperature, flow, and level. Sophisticated analyzers make more complex measurements concerning the composition of one or more components in a liquid or gas chemical stream. Both instrument and analyzer data are used as inputs to automation systems for the purpose of monitoring and controlling the process. Instrument technology has been used for decades and is highly refined, enabling these devices to be directly installed in pipes and vessels, delivering reliable readings with minimal maintenance.  Analyzers for some basic measurements have advanced to the level of instruments in terms of ease of use and reliability. In most cases, analyzers and related sample systems remain quite complex in terms of installation, maintenance, and operations – but recent advancements are changing this paradigm - from the ISA and InTech.

Burner Management Systems

Thanks to our sponsor Invensys Triconex ICEweb's Burner Management System page has around 70 fantastic technical links , many which are new, to assist you if you work in this area.


Cables

Loads of links to cable information can be found on this page.

Ultra-Light, High Performance Electrical Wiring Breakthrough - Super-strong wires made from carbon nanotubes, which could significantly improve the efficiency with which electricity is supplied across the UK have been developed in a usable form for the first time. The wires are one tenth the weight of copper, and, if used in conventional systems, would also make vehicles more fuel efficient. The wires, developed by researchers at the University of Cambridge can also be joined to conventional metal wires, which until now has not been possible.


Choke Valves

ICEweb's Choke Valve page has links to some fantastic technical information. This includes Choke Valve General Information, Choke Valve Design Specification, Choke Valve Maintenance and Inspection, Common Choke Valve Problems and Solutions , Choke Papers and Applications, Subsea Choke Valves, Choke Control Systems and some great links to technical papers.

Mokveld Choke Valves, a Concept that Works - Chokes are critical for the safe and economic production of the world’s oil and gas reserves. In the past simple needle-and-seat chokes were adequate as pressure cuts were low and the applications of adjustable chokes were less demanding. Also, in that era, adjustable chokes employing the rotating disc principle provided satisfactory performance. A number of factors have changed the demands on chokes.  Operating pressures have increased. Safety and reliability are becoming increasingly important. And finally, the economics of the equipment, seen over the life of the field, are vital for the profitable development of the field. The new challenge was met by Mokveld with a proven expertise in control valves. Mokveld pioneered in the use of cages in production chokes. A cage-type choke has a multiple-orifice cylinder - the cage - and a piston which is connected to the stem. The movement of the piston modulates the area of the fluid passage. As a result of the impingement effect generated in the cage-type design, the erosive action of the fluid is fully under control. Also, noise is reduced to safe levels.


Control Valves

A Control Valve Repository which has heaps of great, useful technical information. Fantastic links covering Diagnostic Tools for Control Valves, Valve Sizing, Control Valve Handbooks, Self Operated Regulators, Control Valve Noise Calculation and Prediction, , Positioners, Selection and Application, Maintenance and a mass of other really useful Links to Articles on Control Valves.

Subsea Gas Compression with Mokveld Subsea Control Valves - Mokveld is proud to have been awarded the subsea anti-surge control valves for the Åsgard Subsea Gas Compression Project. Subsea gas compression is a technology approach that can boost recovery rates and lifetimes of offshore gas fields. Aker Solutions - at the forefront of subsea gas compression - was awarded the contract by operator Statoil to supply a complete subsea compression system for Norway’s Åsgard field. The project represents a quantum leap in subsea technology, and an important step in realising Statoil’s vision of a complete underwater plant.

Mokveld Subsea Control Valves Service Norwegian Oil Field - One of the technology gaps to be addressed was the development of large fast-acting subsea control valves. Several operators recognised the unique advantages of Mokveld's axial flow design in topside severe service control applications and approached Mokveld to investigate the axial flow concept as the basis for a subsea control valve.

Large Size Quarter Turn Control Valves can Improve Safety in Pipelines - Carlos Lorusso - Most control valve applications in pipelines are related to system start-up and shut down, emergency operations, delivery control, fluid speed control for pipeline internal examination. Selection of the right control valve is a key factor for long term successful performance for large applications where the safety and security of supply are important considerations. This document presents considerations for control valve selection to improve the safety and operation of oil and gas pipelines. Axial control valves are used when high pressure drop, high flow coefficients, low noise levels and bubble tight shut-off are required. Common applications include compressor start-up, shut-down and High Integrity Pressure Protection Systems (HIPPS). Triple offset valves (TOV) are used for large volume flow control, bubble tight shutoff, pressure drops of less than 30%.Typical applications include delivery point and controlled blow down. Ball valves are used for speed control for intelligent pig travel during pipeline examination and cleaning operations - from Tyco and pipeline conference.

Study Of Flow Instability And Its Implication On A Severe Service Control Valve Using Computational Fluid Dynamics (CFD) - Jeetendra Singh and Sudhakar Paranjothi Rajan - Some valve designs use finned plugs to divide the flow through the seat area into multiple, smaller jets in order to reduce the effective jet diameter, which helps in reducing the noise level in the valve. In this design flow instability develops inside the valve which creates high rotational moment on plug assembly. Anti-rotation pin is used to arrest rotation of plug. In some cases, the turbulent flow can be so severe as to result in the anti-rotation pin breaking. In this paper, analyses have been carried out to study flow instability and its implication on the rotational moment produced.

Cavitation - Of the greatest importance in connection with valves has to be “cavitation”. Cavitation develops if liquids - due to high velocity - evaporate temporarily in the interior of the valve. The bubbles filled with vapor proceed through the liquid flow in the direction of the valve outlet. Due to an inevitable pressure recovery behind the throttling area the bubbles reach a zone of higher pressure and this leads to a sudden implosion of these bubbles. The implosion effect forms micro jets with velocities of up to 500 m/s. During the impact of such micro jets on a firm body (e.g. valve body wall or trim), extremely high local pressure peaks occur which can destroy almost any material very quickly.  

Packing and Gaskets - The chemical industry has carried environmental surveys for many years. These surveys provide valuable information regarding environmental pollution which is usually related to leaking packings and gaskets.  Packings are, in principle, gaskets too, they are, however, in addition exposed to dynamic strain. For the reliability of packings or gaskets there are primarily two factors, Suitable selection of type and material, and regular maintenance, in order to avoid wear and tear and a compression of the sealing element.

Valve Positioner Enables Fast & Precise Control of Large Valves - Where process control applications need larger valves it can sometimes be difficult to achieve the required levels of accuracy combined with fast positioning. Larger valves tend to be fitted with pneumatic actuators which provide significant positioning forces and in these situations the positioning of the valve is achieved by filling the actuator with the corresponding amount of air, or by venting from the actuator. However, the air output capacity required to achieve fast positioning in larger actuators (with diaphragm areas of 1400cm2 up to 2800cm2) is simply too much for normal positioners and accuracy can be compromised.

Pneumatic Boosters - Particularly in association with electro-pneumatic positioners or electro-pneumatic transducers with only a very low air capacity, pneumatic boosters are often indispensable. Smallest forces in these devices must be sufficient to activate the flapper-nozzle system of the electro-pneumatic converter. The volume of the cascade pressure (which depends on the small gap between flapper and nozzle) is, however, very limited through the tiny restriction and subsequently a pneumatic booster is always compulsory. Pneumatic boosters are classified into pressure boosters and volume boosters.

Fugitive Emissions Philosophies for Control Valves -Holger Siemers - It is interesting to compare the use of the bellows seal design versus low emission packing material. The bellows seal design seems to have been forgotten in international discussions and published papers, but it is still unbeatable as regards its life cycle and 'quality of tightness'. In the 'world of valves' under the requirements of fugitive emissions approximately 5% are control valves - thanks to SA Instrumentation and Control.

Limits of Rangeability -The term rangeability was, for a long time, not clearly defined so that it was interpreted in various ways. Even today “rangeability” is often confused with the term „turn-down ratio“ which means the ratio of maximum to minimum flow through a control valve without regarding any tolerances of the inherent flow characteristic, but usually considering flow repeatability. Using this definition and assuming the application of a control valve positioner which guarantees a travel repeatability of 0.5 %, a turn-down ratio of 100:1 and higher can be achieved, while the rangeability, as defined in standard IEC 60534 is not much greater than 15:1. With most trim types, the plug immerses into the seat ring, which requires a minimum gap width, in order to avoid sticking caused by thermal influences or even seizing of seat ring and plug. As a result, an unintentional flow occurs through the gap. This determines the minimum controllable flow and sets natural rangeability limits for any control valve .

Selection of Suitable Materials for Control Valves - The sizing and specifying of control valves presupposes a high degree of experience in order to meet the requirements in an optimum manner. This applies particularly to the selection of the correct materials for the valve body, valve bonnet and internal parts (trim). A “low cost” control valve, composed of unsuitable materials soon becomes very expensive if it has to be replaced after only a short working life. On the other hand a valve consisting of expensive, exotic materials does not automatically ensure long durability if other important influential parameters have been disregarded. A selection of suitable materials is by no means made easy by the wide spread offering of valve manufacturers. One is reminded of pharmacies who also offer prescriptions identical or at least very similar under different names. As a kind of introduction, a systematic survey of common control valve materials should be examined in order to provide an orientation for valve designers and users.

Focus this Quarter on HMI - Lots of Really useful Information!
Building an HMI that Works: New Best Practices for Operator Interface Design - Human Machine Interfaces (HMIs) are requiring a new standard in today’s automation industry. This white paper takes a look at the industry's new best practices for building an effective HMI. You'll find out what's wrong with most HMIs and why, see some of the research behind those that work, and learn specific ways to make yours better. Whether you're starting an HMI from scratch or thinking about adding to or changing yours, the information in this paper will help you build an HMI that increases productivity, saves downtime, and avoids accidents -from OPTO22.
The Myth of ASM® Graphics - How Many Companies Get Burned and Don’t See any ROI - Ian Nimmo - ASM graphics have become a household name and unfortunately anything in grayscale is passed off to be an ASM graphic. Many poor HMI designs are being passed off as ASM Style graphics but most operators can tell that something is not right and refuse to accept the limitations and demand more colour, more graphics and yes, more alarms to compensate for the graphics poor delivery of good situation awareness. So what does good look like? How do you measure it? What is the ROI expected? This session will explain the only way to deliver High Performance HMI using an ISA SP101 approved Philosophy and Style Guide and how to document your Object Library or Dynamo Toolkit - from User Centered Design Services, Inc.

Gray Backgrounds for DCS Operating Displays? - Peter Bullemer, Dal Vernon Reising, and Jason Laberge - With all the sophisticated and cool graphic capabilities available today, why does the ASM consortium recommend such muted and boring colours? The answer involves the human factors behind the selections - To understand the factors that influence design decisions on use of color in operator displays, it is important to understand some basic principles of human sensation and perception. To enhance situation awareness, visual coding techniques are used to draw the operator’s attention to the most critical data and information through enhancing the salience of the associated display elements. An object is more salient than another object if it “stands out,” or grabs one’s attention. In terms of the display design then, this object appears to be in the foreground of the display relative to other objects – from ASM Consortium and Control Engineering.

Using Colour in Information Display Graphics - This site from NASA provides a guide to colour design for information visualization. It includes
- a step by step process for designing colour usage in complicated interface graphics 
- two detailed examples of design of aerospace displays
- a new colour selection tool to support the recommended design process
- information about colour usage standards and guidelines
- information about applied colour science, and 
- reference resources.
Aerospace graphics get special attention, but much of the information should be useful for other colour graphics as well.

Colour Blindness Simulator - Approximately one in twenty people have some form of colour blindness that prevents them from seeing colour the same way that people without any colour vision deficiencies do. Many images and resources on the web are coloured in such a way that it's difficult for users with vision deficiencies to comprehend them. There are many examples in our time, including theatre seating plans where colour blind users couldn't differentiate one section of seating from another! There are a number of colour blindness conditions, including the three simulated by this tool.

Use this Colour Blindness Simulator to reveal how your images may appear to users with a variety of colour blindness conditions. Upload a JPEG image of no more than 1000 pixels x 1000 pixels (100 KB file size or less) to see how colour blind users may see it - from ETRE.

Liberating Operators From The Control Room - There is universal agreement that mobile devices will be making an appearance on more plant floors in the future, although agreement from automation suppliers on a timescale for this to become general practice is less easy to come by. When the maintenance team is trying to repair a failed transmitter or troubleshoot a drive at 2am it is useful to be able to check the inventory system for spare parts or review the online manuals for troubleshooting advice," said Eric Byres, CTO at Tofino Security, a Belden brand. "Being able to do that right where the problem is will be a powerful driver for allowing tablet devices on the plant floor – making maintenance and support the first applications for mobile device technologies in the process factory environment." - from Control Engineering.


Corrosion

Need to know about a corrosion issue? You are likely to find an answer in these pages.

Rust on Stainless Steel - Walter J. Sperko - Rust on stainless steel is ugly. Rust on stainless steel raises a lot of questions. Is the steel really stainless steel? If it’s stainless, why is it rusted? Where does the rust  come from? Will it continue to rust? Will it spread? Will other forms of attack occur, such as pitting or stress-corrosion cracking? This paper addresses these questions for rust that occurs on a tank or pipe that is made from austenitic stainless steel such as Type 304, 304L, 316, 316L, 321, 317, etc. It covers the sources of rusting, the effect of rust on the performance of stainless steel and methods for prevention and removal of rust that appears on the surface of stainless steel components. It applies to rusting on external surfaces of piping and vessels that are exposed to the atmosphere, including rain, condensation, fog, etc. but are actually dry most of the time - from Sperko Engineering Services.

It’s Stainless Steel, it Shouldn’t Rust - This is often the kind of statements heard from individuals when discussing a failure of process piping or equipment. It is also an indication of how little is actually understood about stainless steel and the applications where it is used. For years industries have used stainless steels in their process piping systems. Most of the time stainless steel components provide satisfactory results. Occasionally a catastrophic failure will occur. The purpose of the information contained within this document is to bring an understanding to stainless steel, it’s uses, and why it will fail under certain conditions. This paper discusses  the different classes of stainless steel, heat treatment, corrosion, welding, and finally material selection. As with any failure, it is imperative the cause of the failure be identified before a proper fix can be recognized. Most often the cause of the failure is identified as the wrong material being used in the wrong application - from CSI.

Corrosion and Cathodic Protection Theory - James B. Bushman - This is an excellent reference on the subject - from Bushman and Associates.

Corrosion Protection Of Metals - Two methods of combating corrosion which are widely used in New Zealand are cathodic protection and chemical inhibitors. Both methods depend on controlling the charge on the metal surface, and this can be monitored by measuring the potential of the metal. The conditions needed to stop corrosion can then be predicted from an electrochemical phase diagram - from NZIC.

Pre-release customer testing has demonstrated man-hour savings of up to 30% when compared to traditional design applications. It is quick and easy to deploy and has a very open interface, allowing it to be used with design applications from other vendors or as part of AVEVA’s Integrated Engineering & Design approach. “Electrical & Instrumentation represents 60% of the maintainable items on a plant facility and the data is accessed by operations and maintenance more often than other disciplines,” said Bruce Douglas, Senior VP Marketing & Product Strategy, AVEVA. “AVEVA Electrical can be used both on new projects and also on brownfield activities where the integration of legacy data is critical. We have worked with numerous customers to ensure that AVEVA Electrical does exactly what they need from design to plant operations. Because of its advanced graphical user interface and sophisticated design rules, we believe that AVEVA Electrical will quickly become the preferred choice for all sizes of plant projects.” The open nature of AVEVA Electrical means it can interface with both AVEVA and third-party design, document management and material control systems”, added Dave Wheeldon, Chief Technology Officer, AVEVA. “As part of our Integrated Engineering & Design approach, this product enables electrical engineers to collaborate fully across inter-discipline design anywhere in the world. The automated deliverables generated by AVEVA Electrical are completely consistent and accurate which can dramatically improve productivity and shorten ROI.”

A Shocking Waste of Money - Eight Reasons Why Electrical Design Costs More Than it Should - Electrical engineering and design is one of the most complex and demanding challenges facing EPCs and shipbuilders, in new builds, in-plant projects, and marine refit. Recent capital expenditure on electrical engineering and design has been estimated to reach $3 billion in the hydrocarbon plant industry alone. But should we be shocked by this figure? Surely such a complex discipline necessarily comes with a high price tag? Expense is inevitable, certainly. But wastefulness is unforgivable. Unfortunately, the technology used to plan and design electrical systems, just like that used to design instrumentation and control systems, is often just that – wasteful. Because it has been developed with little regard for engineers’ and designers’ natural working methods, it results in cumbersome and error-prone methods of handling data, and prevents users from making effective technical use of the natural synergies that exist between many activities.

Playing it Safe - How Information Management Technology is essential to meet more stringent Process Safety and Regulatory Compliance - Process Safety and Compliance are universal issues across all the world’s plant industries and individual regulatory authorities are increasingly collaborating to share ideas and to normalise globally consistent, best-practice requirements. These authorities have recognised the potential of Information Management technologies for supporting safe and compliant operations and we can expect to see their use progressively being encouraged, expected and mandated as regulations advance. But the issue is not only one of maintaining regulatory compliance. The US Centre for Chemical Safety claims that an average offshore incident costs an Owner Operator $80 million, so there is a serious economic incentive involved as well.This paper examines current capabilities, opportunities and likely future directions in the application of technology. For convenience, reference will be made to new offshore regulations emerging in the USA, as these are likely to set benchmarks for global regulatory standardisation,

Shift Handover -The Importance of Continuity - Shift handover has been shown to be a common source of revenue loss and safety incidents in plant operation. Both economic and regulatory pressures demand substantial improvement in the shift handover process. Every engineer knows that discontinuities are invariably a source of weakness, whether in physical structures or in continuous processes. This is particularly true in the case of shift handover but, whereas physical discontinuities may be easy to identify and remove, discontinuities in working procedures can be far more difficult. It has long been recognised in the plant industries that the discontinuities of shift handover are among the most common and potentially serious sources of problems. These can range from minor impacts on operational efficiency to the most serious safety incidents; all incur corresponding levels of economic cost. The root of the issue is the transfer of information from outgoing to incoming shift teams. This paper looks into the problems arising and describes how the latest information management technology can be used to overcome them.

Sustainable Energy Management - Putting Information Assets to Work in the Process Industries - This paper outlines the challenges facing process plant operators in implementing effective Energy Management strategies. It describes how these challenges may be overcome through the use of currently available Information Management technologies supported by a comprehensive, Service-Oriented Architecture (SOA). Information Management technology can overcome the technical barriers to effective Energy Management and provide the means to harness an enterprise’s extensive, but often under-exploited, information assets. Such capability supports the key elements of a sustainable, long-term Energy Management programme: best practice methodology and an integrated framework to address its information requirements. Rather than being just a short-term initiative with a single objective, this type of programme constitutes a substantial step on the road to implementing a comprehensive Operations Integrity Management strategy to deliver enterprise-wide business benefits. An Energy Information Management strategy can thus lead to more extensive and sustained optimisation of all aspects of asset operation.

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.

Redesign Blowdown Systems and Alter ESD Practices - When compressor stations are taken offline for maintenance or the system shuts down, the gas within the compressors and associated piping is either manually or automatically vented to the atmosphere (i.e., blowdown).  Emergency shutdown (ESD) systems are designed to automatically evacuate hazardous vapours from sensitive areas during plant emergencies and shutdowns. Some ESD systems route these vapours to a flare stack where they are combusted, while other systems simply vent the evacuated vapours to the atmosphere via a vent stack. Partners report a number of opportunities to reduce emissions from blowdown systems and ESD practices, including (a) Redesigning blowdown systems altering ESD practices (b) Installing YALE® Closures (c) Designing isolation valves to minimize gas blowdown volumes (d) Moving fire gates valves in to minimize blowdown volumes. Department of Transportation (DOT) regulations require that emergency shutdown (ESD) systems at gas compressor stations be fully tested on an annual basis. One common practice is to activate the entire system, which discharges very large volumes of gas to the atmosphere. A DOT acceptable alternative is to test each individual dump valve with the discharge stack blind flanged. This greatly reduces gas emissions, but has higher labour costs associated with installing and removing a blind flange on each ESD valve - from the EPA.


Flow

These pages cover; Coriolis, Metering, Multiphase, Orifice Plates, Ultrasonic, Thermal, V-Cone, Vortex and more!

Thanks to our sponsor McCrometer the V-Cone page has been extensively upgraded with more GREAT links to comprehensive technical information. These include:

V-Cone Meter - Gas Measurement for the Real World - Maron J. Dahlstrøm - This paper describes the performance of the V-Cone meters used for Embla test separator gas measurement. The advantages and disadvantages for use of this technology on the partially processed gas at an offshore platform is discussed. It has been shown in tests that the V-Cone meter functions well with wet gas conditions. The long term repeatability of the meter is documented. Also the low influence from upstream disturbance is confirmed. It is shown that calibration curve fit to ISO5167-1 based equations, can give dry gas accuracy inside the fiscal requirements for gas at Reynolds number above 1 million. The experience from Embla shows that the V-Cone meter tolerates rough operation: The V-Cone meter dimensions certified at six month intervals identifies no changes to the meter. Also the flow calibrations carried out at the same time intervals presents no significant changes, the results match close to the accuracy of the equipment used in the flow calibrations.  

U.S. Navy Adopts V-Cone Flow Meter for EMALS Duty on Next-Generation Carriers - Nick Voss - Defence contractor General Atomics (GA) is developing the next generation of aircraft catapult launch systems for United States Navy’s new Gerald R. Ford-class aircraft carriers. The Electromagnetic Aircraft Launch System, or EMALS, utilizes a breakthrough linear motor technology instead of conventional steam pistons. The Challenge - Accelerating a fully loaded strike aircraft to its launch end speed using linear motor technology generates heat in both the power system and the motors, which must then be dissipated by a cooling system. The cooling water in the system needs to be actively monitored and controlled to ensure proper cooling of these systems, which requires an accurate and dependable flow meter. GA reviewed the available flow meter technologies on the market in terms of their measurement accuracy, dependability and installation space requirements.

Accurate Flow Meter Helps Sugar Mill Measure Steam Consumption of Distillery Plant Producing Bio-Ethanol - Nick Voss - The process engineers at the sugar mill in Latin America needed a new flow meter for steam custody transfer purposes. They were required to measure the steam transferred via a 16-inch line from the sugar mill to its sister company bio-ethanol plant for cost accounting purposes. The mill’s process engineers were looking for a reliable and accurate steam flow measurement solution without routine maintenance requirements for operation in a high-heat, high-humidity dirty plant environment. Choosing a new flow meter can be a complex and time-consuming process. There are numerous flow meter measurement technologies, and not all of them are equally suitable for measuring all fluids: steam, gas or liquids.

Honda Cars Philippines Ensures Quality Manufacturing with Advanced Gas Measurement Solution - Nick Voss - Providing accurate and reliable liquefied petroleum gas (LPG) consumption data for Honda’s oven burners is necessary to ensure accurate production cost and billing as well. Unfortunately, the planned thermal flow metering system could not measure the low end of the LPG flow scale without major changes to the piping system and purchasing a new insert probe. With the plant’s piping space constraints a McCrometer V-Cone Flow Meter was recommended, which due to its compact configuration, required minimal changes to the existing piping system.

NEL Invests in the UK's First High Pressure Multiphase Flow Measurement Facility - NEL has invested £500,000 in the development of a new High Pressure Multiphase Flow Measurement Facility which will create the UK's only facility capable of testing meters to such high pressures. The facility will operate at pressures up to 60 bar to accurately reflect the increasing pressures at which flow meters must operate subsea. It will also replicate a wide range of multiphase flow conditions providing both equipment vendors and operators with an independent facility for development, verification and validation purposes. This will allow oil & gas operators to reduce both capital and operating costs through increased flow meter reliability. The new facility will be commissioned in the last quarter of the year and will be fully operational by the end of 2013. For further information please contact NEL or click here


Ultrasonic Flowmeters

Thanks to ICEweb Sponsor Zedflo our Ultrasonic Flow Metering page has been updated with new links, these include:

How Can Clamp-On Ultrasonic Flow Meters Identify what Product is Flowing from Outside the Pipe? - John Accardo -Many petroleum pipelines flow multiple products such as diesel fuel, gasoline and jet fuel. Between each of these products lies an interface where the flow stream transitions from one product to another. Pipeline operating companies depend on instrumentation to indicate what fluid is in the pipe and when an interface occurs in order to manage the pipeline’s operations. For example, flow arriving at a terminal is stored by product type in specific storage tanks. By knowing when an interface arrives, a valve can be switched to route the new fluid to its respective tank. Certain additives (e.g., Drag Reduction Agent “DRA”) may only be injected for specific fluids. So, you can see that knowing what fluid is presently in the pipe is critical to proper operation of the pipeline. Using a non-intrusive instrument for this purpose adds another level of benefits, including low cost installation, no loss of pressure, no interruption of the DRA, and the ability to allow pig passage through the measurement point.

Siemens SITRANS FUS1010 Clamp-On Flowmeter Installation Guideline - In this Video learn how to get started with the FUS1010 clamp-on ultrasonic flowmeter, including identifying and selecting sensors, choosing a mounting location and programming the meter.

Fire and Gas

Technical Papers covering many aspects of Fire and Gas Engineering. Thanks to Honeywell Analytics this page has been extensively re-modelled with many new links added.

Honeywell Analytics Gas Book - This updated handbook is intended to offer a simple guide to anyone considering the use of gas detection equipment. It provides an explanation of both the principles involved and the instrumentation needed for satisfactory protection of personnel, plant and environment. The aim has been to answer as many as possible of the most commonly asked questions about the selection and use of industrial gas detection equipment.

Visual Alarms - Why are visual alarms required? - One American in a hundred has a severe hearing loss; nearly one in ten has a significant loss. In 1984, the Digest of Data on Persons with Disabilities reported that: "(the severity of hearing problems was strongly associated with age. persons 65 and older constituted 69 percent of the population with the most severe hearing trouble...but only 8.7 percent of the population without hearing trouble." Those who are deaf or hard-of-hearing, a growing percentage of our population, due largely to the growth in the numbers of older persons depend upon visual cues to alert them to emergencies. A visual alarm provides persons with hearing loss the same warning delivered to hearing persons by an audible alarm. Audible fire alarms have been a standard feature of building construction since the life safety codes of the early 1900s. However, visible signals did not appear even in accessibility codes until 1980. Early standards required relatively dim flashing lights at exit signs, an alarm system that was effective only along an exit route. As accessibility, life safety, and building codes were revised, however, they began to incorporate alarm technology that was developed for use in schools for persons who are deaf and in factories where ambient noise levels made audible alarms ineffective - from US Access Board.

Protection of Piping Systems Subject To Fires and Explosions - This document aims to fill this gap by providing guidance on the protection and response of piping systems and piping supports subject to fires and explosions. The guidance covers the methods used to carry out both simplified design checks and advanced non linear analysis - from HSE (UK).

Fire Systems Integrity Assurance - Experience has shown that fire detection and protection systems are not always designed or specified in sufficient detail to ensure that they meet the performance criteria necessary to reliably achieve their intended role; this can result in fire systems not providing the performance required when called upon to do so. The OGP has produced a Fire System Integrity Assurance report, which provides guidance on issues involved in the assurance of fire system integrity from development of appropriate performance criteria through to routine system testing and inspection, in order to assess ongoing performance against the original criteria. The objective of the report is to provide a high level model of the steps to be addressed in assuring fire system integrity and to give guidance on technical points to be considered at each stage, drawing on practical experience from oil and gas installations - from OGP.

New Flame Detector - ProDetec, a leading Fire & Gas Detection company, have announced  the availability of the new Simtronics MultiFlame DF-TV7 series flame detectors that provide fast and accurate detection of hydrocarbon fires while ensuring reliable false alarm immunity. The new Simtronics flame detectors is available in Multispectral IR (IR3) and UV/2IR versions; both are housed in a rugged 316 stainless steel enclosure, approved to ATEX, CE, and IECEx global standards, and certified and suitable for use in SIL2 applications. 
The Simtronics DF-TV7-V flame detector is based on a multi-infrared spectrum (IR3) technology that provides the longest distance-to-detection on the market (80m for n-Heptane), is highly sensitive to fire and is ideal for use in dirty environments and for smoky fires. The Simtronics DF-TV7-V flame detector uses combined ultraviolet/infrared (UV-2IR) optical technology that provides industry-leading immunity to false alarms based on the two IR channel design. Both solutions lead to a very efficient false alarm rejection while keeping optimum sensitivity to fire.

Fire Prevention Requirements for Information and Communication Technology (ICT) rooms - Best Practice Document - This document provides specification of the Norwegian HE sector’s recommended fire protection requirements for ICT rooms. The aim of this document is to raise personnel awareness concerning the fire protection issue, and to enhance the quality of fire protection measures within the sector. Furthermore, it is intended that the recommendations in this document will form the basis of expansion, renovation and new building projects, and that they will be applied in everyday work contexts.

The person in the field can now look at a piece of installed equipment and the app provides them with the ability to confirm that there is a valid certificate for the apparatus on the IECEx online Certificate System.

Hazardous Area Classifications and Protections - The intent of this document is to provide a broad overview of hazardous area classifications and the types of protection techniques involved – from Emerson Process Management.

How to Make Sure Your Dust Collection System Complies with Combustible Dust Standards  - Tony Supine and Mike Walters - Combustible dust explosions are a risk in many areas of a plant, but one of the most common locations is the dust collection system. How do you know if your dust collection system complies? What do you do if it doesn’t? Are your employees at risk? What are the hazards and how do you identify them? The National Fire Protection Association (NFPA) sets standards and codes to protect buildings against fire and explosion risks, and the Occupational Safety & Health Administration (OSHA) is applying these standards with increasing vigilance. When it comes to combustible dust, several standards must be considered. This white paper reviews the current status of the OSHA National Emphasis Program for combustible dust, the NFPA standards that address how to prevent or limit explosion hazards, how to identify these hazards, and the types of equipment used to eliminate or control explosion hazards. We will also examine the most common shortfalls to compliance and how to avoid them - from Camfil.

Ex d Enclosures: Understanding the Standards - Toni Ott - When specifying explosion-proof (Ex d) enclosures to house electrical apparatus for use in explosive atmospheres, engineers need to understand the implications of modifying the enclosure as part of the certified equipment prior to and after installation - from Control Engineering.


High Integrity Pressure Protection Systems - (HIPPS)

A swag of information on this interesting subject.

High Integrity Pressure Protection System (HIPPS) - Andrew Chu - A High Integrity Pressure Protection System (HIPPS) is a Safety Instrumented System (SIS) designed to prevent an unsafe condition caused by pressure arising (e.g. due to separator outlet blocked in the choke valve downstream, blocked pipeline, etc).  The decision to utilize a HIPPS in addition of utilize a PSV shall be based on the study of risk. The aim of this study is to determine a certain SIL requirement. This study will conclude whether some process condition need to have a HIPPS or its ok to protect it by a PSV valve only - from the Instrument Engineers Blogspot.

HIPPS ...for Cost-Effective Risk Reduction - Ken Bingham and Scott Lawson - With the oil and gas sector booming, many hydrocarbon processing facilities are trying to increase production to meet rising demand. These plants, initially designed and engineered, sometimes decades ago, to deliver a specific level of production, are being expanded or revamped in some way. When new gas production sources are tied into a gas plant, for example, the existing pipelines and processing equipment face the risk of overpressure in excess of design capacity. This may result in the unplanned release of hydrocarbons into the atmosphere via a triggering of a mechanical relief device such as a PSV (pressure safety valve), the undesirable burning of these hydrocarbons through the flare system or the worst case scenario of a rupture, fire and explosion. With the adoption of various standards including ASME, API, and the performance based, non-prescriptive standards IEC 61508 and IEC 61511, conventional thinking is evolving to include the application of high reliability safety instrumented systems (SIS) to replace and lessen the need for additional PSVs and expanded flare systems. HIPPS, an abbreviation for high integrity pressure protection system, is a specific application of a SIS designed in accordance with IEC 61508 which is growing in popularity. With HIPPS, the protection against overpressure is achieved by quickly isolating the source causing the overpressure, as compared to conventional relief systems where the overpressure is relieved to atmosphere - from ACM.

Optimising Pressure in Subsea pipes with HIPPS - Jacob G. Hoseth, Bernard Humphrey - Most of the ‘easy’ oil fields have now been discovered, making it likely that new fields will be more difficult to develop than in the past. For those fields where high pressure is the main technical challenge, a subsea High Integrity Pipeline Protection System (HIPPS) which, by confining the high pressures to the wellhead area, allows existing infrastructure to be used. When subsea HIPPS is installed, the flowline and riser pipe wall thickness can be rated to just the flowing pressure. A modularised, flexible system, subsea HIPPS helps oilfield operators to reduce the cost of developing pipeline solutions without compromising safety - from ABB.

API RP 17O - Recommended Practice for Subsea High Integrity Pressure Protection System (HIPPS) - This RP addresses the requirements for the use of high integrity pressure protection systems (HIPPS) for subsea applications. API 14C, IEC 61508, and IEC 61511 specify the requirements for onshore, topsides and subsea safety instrumented systems (SIS) and are applicable to HIPPS, which are designed to autonomously isolate downstream facilities from overpressure situations. This document integrates these requirements to address the specific needs of subsea production. These requirements cover the HIPPS pressure sensors, logic solver, shutdown valves and ancillary devices including testing, communications and monitoring subsystems. You will need to purchase this standard.

HIPPS-Based No-Burst Design of Flowlines and Risers  - Nikolaos Politis, Hugh Banon, and Christopher Curran - A methodology is proposed for design of subsea flowlines and risers coupled with a subsea high-integrity pressure protection system (HIPPS) for fields with high shut-in tubing pressure (SITP). The proposed approach uses a design pressure that is lower than the SITP while maintaining a high reliability against burst failure. This approach enables an inherently safer design and ensures that the system integrity is not compromised in the unlikely event that HIPPS valves fail to close upon demand. The proposed design methodology is supported by a combination of analytical and experimental results. Further, an example is provided for demonstration purposes - from spe.org

DNV HIPPS - An introduction to High Integrity Pressure Protection System (HIPPS) as utilised on high pressure Subsea Systems - from DNV.

Subsea HIPPS - HIPPS is an instrumented safety system that is designed and built in accordance with the IEC 61508 and IEC 61511 standards. Additionally API RP 17O – Recommended Practice for Subsea HIPPS - provides guidelines for using the IEC standards in subsea systems. These international standards refer to safety functions (SF) and Safety Instrumented systems (SIS) when discussing a solution to protect equipment, personnel and environment. A system that closes the source of over-pressure within 2 seconds with a determined reliability level is usually identified as a HIPPS. A subsea HIPPS is a complete functional loop consisting of; (a) The initiators that detect the high pressure (b) A logic solver, which processes the input from the initiators to an output to the final element and (c) The final elements, that actually perform the corrective action in the field by bringing the process to a safe state.  The final element consists of a valve and fail safe actuator and possibly solenoids.

Checklist for Pressure Sensor Selection - 15 Tips to Ensure Performance Meets Your Expectations - Elden Tolman - We have all experienced the frustration of a problematic sensor, even when the supplier tells us everything seems to be working properly. What we often find is that while the sensor may be “working,” it is often not the right sensor for the application. Successful pressure measurement usually comes down to one thing—selecting the right sensor for your application. There are so many considerations that it is easy to overlook a key element until it’s too late. Nearly a decade of working with pressure sensors in various applications has convinced me that the most common reason for problematic pressure measurements is the failure to select the right sensor. Even industry veterans can fall into this fine spun trap. This article presents 15 fundamental considerations when selecting a pressure-sensing device- from Flow Control Network.

Specifying A Pressure Transducer – How To Select Pressure Range And Device Type - Mitch Berkson and Dave Field - When choosing a pressure transducer for a particular application, usually the first question which arises is: “For what pressure range should the transducer be rated?” This simple question begets a bevy of related ones, namely: “What is the pressure range in which the device typically operates? Does the device occasionally need to measure pressures outside this range? What pressure must the device withstand and still operate within specification when returned to its normal range? What pressure must the device withstand without failing even if it will function properly after returning to the normal operating range?” Closely related to the pressure specification is the type of device to choose - absolute, gage or sealed gage. The following sections will first address pressure

Finding, Measuring and Closing Safety Integrity Gaps - How Modern Process Safety Management goes beyond Functional Safety to Keep your Plant Continuously Safe and Profitable - Steve J. Elliott - Functional safety focuses on the safeguards required to manage and mitigate hazards. It seeks to answer the following types of questions: What can go wrong? (Hazard identification), How severe might it be? (Consequence assessment), How likely is it to happen? (Frequency assessment), Does it matter? (Risk assessment) and Do we have enough protection? (Layers of protection assessment.) Safeguards typically include safety instrumented systems (SISs) such as emergency shutdown systems (ESDs). They also includes alarm functionality of the distributed control system (DCS), burner management systems and pretty much any other automation and control technology that provide a layer of protection that enables safe operation. But regardless of how well designed, functional systems are only fully effective if operated and maintained properly, and growing awareness of this fact has given rise to the newer discipline of process safety.

Real-Time Profitable Safety - Improving Safety and Environmental Integrity to Improve Profitability - Peter Martin - Safety of people, equipment, facilities and the environment is becoming increasingly important in industrial operations. This is not just because of highly publicized accidents or even for altruistic reasons. Rather, it has become evident that the safety of an operation is directly linked to profitability. Although it is true that industrial executives are very concerned over the safety of their operations, it’s the increased profitability potential that can be realized through more effective safety management that is really starting to turn heads and to truly bring safety and environmental integrity into the mainstream of industrial business processes. For decades industrial professionals have recognized that the cost of unexpected events, such as fires or explosions, can be very high in terms of injury, death, equipment damage, facility damage, environmental damage, business interruption, and insurance. Industry has responded to this high potential cost through functional safety programs such as installing safety instrumented systems to detect pending unsafe conditions and automatically taking the correct response. These systems have proven to be very effective at the avoidance of predefined unsafe events and certainly represent a huge step forward. But cost avoidance of unexpected events represents just a small piece of the overall potential profitability impact that may result from an effective safety control solution. The “cost avoidance” perspective tends to be too easy for business executives to turn a blind eye to because they are lulled into believing that unsafe events will hit other businesses, not theirs. Unfortunately this tends to be an all too human thought process for all kinds of similar events which seem to have served to inhibit capital spending on safety improvement initiatives.

At Bluewater, the clearest path to Modernization is through Invensys - This Project had several goals; (a) To replace and upgrade the existing integrated control and safety systems. (b) To achieve ‘First Oil’ on time in order to avoid contract penalties and lost production and (c) To maximize the availability/uptime of the control and safety systems and to minimize the total cost of ownership. Also there were challenges which included; The Project teams located in multiple locations, Process data from the new ICSS, including serial interfaces, safety systems and new I/Os, were available only in the very late stages before the planned FAT and  the original DCS had to be kept ‘alive’ as long as possible and the existing safety systems were required to remain operational with just a few hours available to upgrade.

Complex Turbomachinery Control System Upgrade - In a highly complex gas turbine application, Invensys modernized a peaking generator at a power plant in the MidAtlantic region of the United States. As a result the generator’s reliability and availability significantly increased. During the modernization process, Invensys encountered a number of challenges. Many were related to the overall complexity of startup, logic, and wiring. Others arose from a lack of proper documentation for existing system operation and upgrade history.

Safety & Automation System (SAS) - How the Safety and the Automation Systems finally come together as an HMI - Ian Nimmo - Today we have clear guidelines on how the Safety Instrumented Systems (SIS) and basic Process Control Systems (BPCS) should be separated from a controls and network perspective. But what does this mean to the HMI and the control room design? Where do Fire & Gas Systems fit into the big picture and what about new Security and Environmental monitoring tasks? What does the Instrument Engineer needs to know about operators and how systems communicate with them. The evolution of the control room continues as Large Screen Displays provide a big picture view of multiple systems. Do rules and guidelines exist for this aspect of independent protection layers? What are today’s best practices for bringing these islands of technology together. This paper reviews the topic and provides advice on a subject on which the books remain silent. Today’s practices are haphazard and left to individuals without a systematic design or guidance - from Plant Services.

Standard - Design of Safety Significant Safety Instrumented Systems Used at US Department of Energy  Nonreactor Nuclear Facilities - This standard provides requirements and guidance for the design, procurement, installation, testing, maintenance, operation, and quality assurance of safety instrumented systems (SIS) that may be used at Department of Energy (DOE) nonreactor nuclear facilities for safety significant (SS) functions. The focus of this standard is on how the process industry standard, American National Standards Institute/International Society of Automation (ANSI/ISA) 84.00.01-2004, Functional Safety: Safety Instrumented Systems for the Process Industry Sector, can be utilized to support design of reliable SS SISs - from the USDOE.

Demanding Performance Requirements of Oil and Gas Industry Require Careful Safety System Selection - Striking the right balance helps optimise investments, enhance safety and reduce lifecycle costs - Asset and system availability along with process uptime are more critical than ever in the oil and gas industry. At today’s high fuel prices, each minute of uptime counts. Any disruption of the supply chain creates a strain in the market and puts companies at risk for incurring substantial downtime losses. While safety is a concern across all manufacturing sectors, it is especially critical in the oil and gas industry. In this environment, risks can be far-reaching. The spill of a toxic agent or explosion could harm the entire plant or surrounding community. The inability to respond effectively to hazardous situations can be extremely costly from jeopardizing personnel to diminishing the bottom line, brand reputation, or consumer and investor confidence. This white paper provides an overview of available safety system options, key vendor and technology considerations, and pros and cons of common design approaches. It also highlights some of the business benefits companies can gain by implementing intelligent safety systems, including helping improve worker safety, asset protection and availability, reduced labour costs and increased overall equipment effectiveness – from Rockwell Automation.

Engineering Maintenance of Safety Instrumented Functions - Early Involvement Improves Operations and Maintenance through the Safety Life Cycle - Henry Johnston and Fahad Howimil - International standards for safety instrumented systems (SIS) have had a profound influence on the analysis and design of these protection systems. The old prescriptive or recipe type was changed to a performance approach that designers must satisfy. The first stages of the safety life cycle (SLC) are now well known by a majority of designers and engineers involved in SIS; however, such grade of understanding and influence has not been widely accomplished at the final stages of the SLC as are the operation and maintenance (O&M). O&M involvement in the engineering of SIS is normally passive, participating in specific analysis when requested. Such approach leaves almost the complete engineering of the protection system under project designer “responsibility.” An early involvement with a proactive approach to complement the designer experience with reliability and maintainability vision is necessary to balance the design and to manage the SIS - from the ISA and InTech.


Safety

Evolution of Asset Management Standards in Hazardous Environments - This overview from BSI, the British Standards Institute, looks at asset management standards for organisations operating in hazardous industrial environments.  

Human Factors: Procedures and Instructions - ‘Human Error’ has long been identified as a contributing factor to incident causation. Commonly cited statistics claim that human error is responsible for anywhere between 70-100% of incidents. It seems logical, therefore, to blame incidents on individuals or small groups of people and to focus remedial actions at the individual level (e.g. training, disciplinary action, etc.). However, by taking this approach in addressing human error, organisations ignore the latent conditions in their work systems that contribute to human error across the workforce. Rather, human error should be recognised as an outcome of combined factors, instead of the root cause of an incident. Organisational, job, and individual factors all interact to influence human reliability, that is, the likelihood that an individual will perform their task effectively or make an error. This publication forms part of a series of information papers focusing on human factors. NOPSEMA defines human factors as “the ways in which the organisation, the job, and the individual interact to influence human reliability in hazardous event causation”. Reliable behaviour results in desired performance, while unreliable behaviour may result in human error, which can lead to events and near misses - from NOPSEMA.


Security

This comprehensive page has numerous technical papers on Process Control Security issues

SCADA Security Directions 2013 - Five predictions for 2013 from Eric Byres.  

The following videos are from Tofino Security, it is recommended that they are viewed in the following sequence;
(1) What is Cyber Security?  - Our modern lifestyle relies on critical infrastructure and industrial plants that use complex networks of computers, PLC controllers, remote terminal units and other specialized equipment. However as these industrial networks have become more complex and interconnected, Cyber Security becomes more and more important to ensure their continued safe and reliable operation. This video examines the current state of cyber security in SCADA and industrial control networks, talks about how we got to this point, and lays the foundation for discussing how to improve the security of these systems.
(2) We're Secure - We Have A Firewall! - Many companies already use firewalls to isolate the plant and enterprise networks. What's so bad about this approach? Aren't these networks already protected? In this video, we'll explore the types of cyber security issues we often see in plant networks and learn how these issues can impact plant operations in spite of these firewalls.
(3) Security Strategies that Work on the Plant Floor - The previous video in this series showed that a firewall on the plant network could not protect us against many cyber security threats. But if that doesn't work, then what ARE we supposed to do to protect our plant? IT engineers have been dealing with cyber security issues for years. This video examines the security strategies that they have found to work, and see how we can implement them on the plant floor.
(4) Why Is Cyber Security still a Problem in SCADA and Control Networks? - IT engineers have been dealing successfully with cyber security issues for years, and there are many security products in daily use in enterprise networks. Why is cyber security such a challenge on control networks? Why can't the same tools and techniques be used to secure these systems? The answers to these questions lie in understanding the unique requirements of control and SCADA networks, and applying cyber security strategies in ways that are appropriate to these applications.
(5) How does Tofino Protect my Plant? - Previous videos in this series have discussed how Defence in Depth can be an effective strategy to secure control networks. So how exactly does Tofino implement Defence in Depth? And what makes it the best solution? This video takes a deeper dive into the components of the Tofino Industrial Security Solution, and examines how they work together to implement cyber security on the plant floor.

US Energy Department Launches Public-Private Initiative to Help Oil and Natural Gas Industry Strengthen Its Cybersecurity Capabilities - As part of the Obama Administration’s commitment to protecting America’s critical energy infrastructure, U.S. Energy Secretary Ernest Moniz today announced a new public-private partnership to strengthen protection of the nation’s oil and natural gas infrastructure from cyber attacks. Led by the Energy Department in collaboration with industry experts, the Department of Homeland Security, and other stakeholders, the initiative will create a tool that allows owners and operators to assess their cybersecurity capabilities and prioritise their actions and investments to improve cybersecurity. “As cyber threats continue to increase in frequency and sophistication, helping critical infrastructure owners and operators across the energy sector identify opportunities to strengthen their own cybersecurity capabilities is a top priority,” said Secretary Moniz. “Building on the successes in the electricity industry, this initiative for the oil and gas sector is an important step in moving us closer to achieving the Department’s vision of resilient energy delivery systems that can survive a cyber incident while sustaining critical functions.”

Surge and Lightning Protection

It will never happen to me? Don't you believe it...Globally, some 2000 on-going thunderstorms cause about 100 lightning strikes to earth each second!! This page provides a comprehensive range of links to help resolve the potential effects.

The following links are from ICEweb sponsor IDC Technologies.
Lightning Protection for Industrial Plants - Phillip Tompson - This paper provides an outline of a systematic approach to determine and apply lightning and surge protection to industrial plants such as water and sewerage and oil and gas facilities. All too often when lightning strikes an industrial plant, equipment is damaged and operations curtailed there is an initial rush to get the plant operational again. This is a reasonable response. Then comes the question of how to protect the plant against the next lightning strike. Inevitably the approach taken is ad hoc and the result is very often a lightning protection system that does nothing to protect the equipment that was originally damaged. Indeed by taking a systematic approach, applying the Australian standard, carrying out a risk assessment, then acting upon the results of that risk assessment both cost effective and successful solutions can be found.
Accurate Soil Resistivity Testing for Power System Earthing - Rodney Urban, Karl Mardira - Soil resistivity data is of fundamental importance in performing earthing system analysis. Reliable data is required to achieve good correlation between design and measured earthing system performance. The findings of numerous soil resistivity tests in the Sydney area for rail system earthing design is presented in this paper. The installations were inside the rail corridor where testing was often very restricted or not possible due to hazards, space limitations and adjacent buried metallic services or structures. A comparison of the results indicates the possible variation of soil resistivity at various depths over small distances and how this can be accommodated in the design process.
Arrester Earthing Resistance - Tony Gillespie - An analysis of the earthing resistance for surge arresters on the distribution network. The simplified analysis is based on lumped parameter circuit impedance values for a lightning strike.
Power System Earthing Due Diligence - Gaye E Francis and Richard M Robinson -  There have been two primary paradigms of safety risk management co-existing uneasily over the last few decades. One is related to hazard based risk analysis driven by technical professionals using target levels of risk and/or safety. The other is the precaution based risk analysis driven by the courts focusing on ‘due diligence’ being a demonstration that all reasonable practical precautions are in place based on the balance of the significance of the risk vs the effort required to reduce it. The publication of the EG-0, Power System Earthing Guide, Part 1: Management Principles by Energy Networks Australia in May 2010 supports the hazard based / risk target approach to risk management whilst the impending (2011) national Model Workplace Health and Safety Act requires a positive duty of care for responsible officers to exercise ‘due diligence’. This paper will investigate the underlying conflict between the two positions and the manner of expected resolution using EG-0 as the focus.


Test and Calibration

Technical Papers and Articles on how to test and calibrate along with typical equipment. Thanks to our sponsor Zedflo Australia ICEweb's Test and Calibration Instruments page has been extensively upgraded.

The Following are from the very useful InstrumentationPortal.Com
Calibration Form - Calibration forms provide a list of actions to be done when performing instrument calibration. Instrument Calibration is required to make sure that instrument will function properly prior to installation. Before shipping, vendor has already done the calibration after setting the range to pre-determined value as requested by the end-user. It is common by contractor to re-check the instrument by performing bench calibration. However, some end-users prefer to install the instrument without undertaking this test. Following are some typical calibration forms for transmitters, gauges and control valves.

Control Valve Calibration Form
Pressure Gauge Calibration Form

Ultimate Calibration - 2nd Edition - This calibration handbook covering various topics about advanced calibration comprises 203 pages and 19 articles - Calibrators, calibration software and other related equipment have developed significantly during the past few decades in spite of the fact that calibration of measurement devices as such has existed for several thousands of years. Presently, the primary challenges of industrial metrology and calibration include how to simplify and streamline the entire calibration process, how to eliminate double work, how to reduce production down-time, and how to lower the risk of human errors. All of these challenges can be tackled by improving the level of system integration and automation. Calibration and calibrators can no longer be considered as isolated, stand-alone devices, systems or work processes within a company or production plant. Just like any other business function, calibration procedures need to be automated to a higher degree and integrated to achieve improvements in quality and efficiency. In this area, Beamex aims to be the benchmark in the industry. This book is the 2nd edition of Ultimate Calibration. The main changes to this edition include numerous new articles and a new grouping of the articles to make it easier to find related topics. The new topics covered in the edition mainly discuss paperless calibration, intelligent commissioning, temperature calibration and configuring, and calibration of smart instruments - from Beamix.

Temperature

Covering a whole range of temperature measuring techniques along with General Theory, Conversions, Selection and Application this page must be your first choice when looking for quality technical information.

Thermistors As Accurate Temperature Sensors - Introduction and Methods - Darren O'Connor, and Kasandra O'Malia - This two-part article describes how to use a simple voltage divider circuit with a thermistor to achieve high-accuracy temperature readings over broad measurement ranges. Part 1 discusses the circuit and various temperature estimation methods. Part 2 of this two-part article shows a method to a real-world application and how, by combining estimation methods with thermistor characterization data, high accuracy measurements can be achieved over a wide temperature range using the simple voltage divider circuit - from Sensors Magazine.

theworm facing right logo Get Rid of Rigid - Get The WORM Flexible Temperature Sensor - Flexible temperature sensors are the new frontier in accurate temperature measurements and easy maintenance. The WORM’s mission: to fit nearly everywhere, to be quickly cut to the correct length, and to reduce the number of spare parts a plant has to keep on hand. The WORM is a flexible sensor for thermowell temperature assemblies. It was designed to replace restrictive, rigid, straight sensor probes with a universal strategy that saves time and money. When it comes to flexible and rigid temperature sensors, both can be inserted into thermowells or protection tubes, welded into place on boiler tubes or other objects, or clamped down for surface measurements. Both types of sensors are rugged, durable, and can measure a wide range of temperatures in industrial applications. So, why replace rigid, straight sensors?  Additionally see a Video outlining the features here.

Basics of Thermowell Design and Selection - Do not underestimate the importance of thermowells in temperature measurements - When planning for a temperature measurement application, a fair amount of consideration is typically given to sensor selection (e.g., thermocouple vs. RTD) and wiring of the output (e.g., transmitter vs. direct wiring), and how these factors will affect the measurement. Often, by comparison, relatively little consideration is given to the mechanical components of the sensor assembly, particularly the thermowell. Of all the components in a typical temperature assembly, a thermowell would seem to be the simplest and least critical. In reality, the thermowell is fundamentally important because it directly and significantly affects the life span of the sensor and accuracy of the measurement. It also protects the closed process, providing plant and personnel safety - from ISA and InTech.

Practice Always Makes for Perfect Presentations - Most engineering professionals will readily confess that they are not overly enthusiastic about making presentations. Often the reason is that they are nervous, the presentations come across poorly and it is not a particularly pleasant experience for both the audience or the presenter. You’re unlikely to ever hear from someone, who has to attend a presentation, that they are looking forward to it. However, doing a high quality presentation is a key part of every engineer or technologist’s toolkit. And helps make your career and job considerably more successful. And by application of one simple rule (sounds like black magic or a quick get rich scheme doesn’t it?); you can dramatically improve your presentations. And that is practice. Going through one’s slides a few times is often tedious and unrewarding work (like discovering your old smelly running socks in your backpack a few weeks down the track?). But it works; and pays off with great feedback from your audience.
