CVE Software: Alarm Limit Calculation Tool

ProcessVue Software

ProcessVue combines over 20 years of experience in design and implementation of Alarm Management and Printer Replacement software, with the latest communication, data logging and reporting technologies. Providing clear, relevant and prioritized information to Operators, Supervisors and Managers is critical to decision making whether in the control room or the board room. All this in a easy to use standard web based client.


· Advanced KPI Reporting Based on EEMUA 191 Guidelines
· Alarm System Benchmarking
· Alarm Rationalization
· Automated Reports
· Simple Printer Replacement
· Alarm and Event Analysis
· Alarm and Event Archiving
· Open MS SQL Server Database
· SQL Reporting Service for User Defined Reports
· Web Based Clients
· Secure Service Oriented Architecture
· vmware® Friendly
· Integration with existing IMAC systems.

ProcessVue is scalable and can be used as a simple out of the box standalone printer replacement package or bring together multiple disparate systems into one common platform offering advanced alarm management. Parsing rules allow even the most complex and variable data types to be formatted into single line meaningful alarms and event messages. ProcessVue uses Microsoft SQL Server for easy access and integration to existing 3rd party packages for data mining.

ProcessVue has Open Connectivity allowing data to be reconstructed and sent to third party applications as well as using standard MS SQL Server technology. ProcessVue uses the latest Ajax zero footprint web client technology, allowing simple rollout, in even the most demanding IT environments across multi platform operating systems.

CVE Software: Success Story

Poorly configured alarm limits may be the reason why you have alarm floods and nuisance alarms. The CVE software uses your alarm limit settings and historian data to create a picture. This picture allows you to easily see which alarm limits to change and what to change them to. This visual representation, will surprise you. You can see alarms that are set way outside your operating range, alarms that never activate. These might be valid alarms but the picture clearly shows that you need to change the alarm limits to support your operating objectives. You will see alarm limits that are too far inside your operating range, these alarms are always activating. If your normal operating range is good, and you’re meeting your objectives, simply move the alarm limits around your objective. This will immediately reduce nuisance alarms and support your healthy operating range. The CVE software also allows you to see before and after pictures, so you can test your alarm limit changes to see the effects before you make the change. A picture is worth a thousand words in and in this case, this picture might save you thousands of dollars on your alarm rationalization project.

More Info on CVE Software:
Almost all the problems of operator alarm systems start (and can be ended) with the values you assign to the operator alarm limits. There was little guidance and no method for finding these values in the past. EEMUA 191 and ISA SP18.2 both give very general guidance to “position the operator alarms around the boundary of where you normally operate” but with no advice on how to locate that boundary for every alarmed process variable.

Our Operating Envelope- based method implemented in CVE is very fast and easy to apply and shows you “the boundary of where you normally operate” within minutes. CVE provides Alarm Performance Prediction so that you can set your alarm limit values to be ‘right-first-time’ when you put them into use.

Once you have positioned alarms correctly (and you should only need to do this once unless you make major process changes) you will have eliminated the majority of false alarms. This alone will, over time, substantially increase the operators belief in the few alarms that remain so that requested alarm actions will be made sooner and you will see an improvement in process performance as a result.

You will learn a great deal about your process and its strengths and weaknesses just from seeing the inter-relationship of operating limits, MPC constraints, operator alarm limits, pre-trip limits, trip-limits and safety limits all in one picture for hundreds of process variables. This is valuable as a one-time exercise but much more valuable when performed on a regular basis as a Process Stewardship activity where it contributes to operating your plant at its best efficiency for more of the time than you do today.

UCDS has in-depth experience in designing control rooms and modifying existing field shelters. Our process is compliant with the ISO 11064 Ergonomic Design Standard for Control Buildings. We interview management, supervision and a significant group of the operators to understand functional requirements, what works well in the existing environment, and identification and correction of problems with the existing design.

Situation Awareness

Abnormal situations encompass a range of events outside the “normal” plant operating modes, e.g. trips, fires, explosions, toxic releases or just not reaching planned targets. In the past incidents such as Piper Alpha, Milford Haven, Flixborough, Texas City and the 2003 northeast electrical blackout have all been attributed, at least in part, to a fundamental lack of good situational awareness. Early work of the Abnormal Situation Management Consortium® included a survey of the US petrochemical industry. Based on their research the consortium estimates industry losses of around $20 billion per year from abnormal situations, approximately equal to the total annual profits of that industry. Furthermore these studies indicate that companies achieving Best Practices in operations can improve productivity by 5-12%. To learn more Click Here


Fatigue Alertness Management

We have many customers looking to enhance their shift handover procedures and follow some of the Recommended Practices identified in the API documents; others are focusing attention on fatigue and fatigue countermeasures. We have great solutions for both these topics. For more details please contact Steve Maddox. To learn more Click Here



User Centered Design Services promotes Behavior – Based Safety which is a process that helps employees identify and choose safe behavior over an unsafe one. Safety in the workplace is a combination of three measurable components – the person their environment, and their behavior. To learn more Click Here

About the Control Room Operator Performance Group

The purpose of this group is to share ideas and solutions that contribute to improving the performance of the control room operator. Abnormal situations can be managed safely and effectively if we provide our operators with the right training, workload, environment, and interfaces.
