  • This is a sample alarm from a DCS. It shows a low level alarm on a reservoir. This is what alarm systems usually do: indicate a measured value passing a limit. Or This is what we call an operational advisory. It refers to the bigger picture (the compressor train), it informs the operator he is running on fuel, not on gas and it advises the operator to take an action, either switch back to gas or fuel up within a given time frame. I would know what I would like to see. But you know what? This not just any sample alarm of an imaginery DCS. The first message is an example from a customer data log we analysed. And you know what? This message did not appear in the log! We suspect it was rationalised away. So, the next message we did found in the log was: no fuel (the low-low limit), which implied practically immediately, no power, and a compressor trip, resulting in bunch more alarms. Of course we built logic to alarm the operator. Why was it built in UReason software? Well, making an association between tag information, the related asset and the connected assets of that asset, is something a DCS is not designed for. Forget about what DCS vendors and other vendors might tell you. Our customers tell us: there is only so much you can do in the DCS, it takes too much effort and we can hardly maintain it. Note that with modern technology, you can click on a hyperlink and go to the asset, to the underlying information or to the operating instructions.
  • This is a picture taken from the Rotterdam Shell Refinery. This big blast was caused by a drop of the power lines. Not something our software can prevent, but it resulted in a bunch of alarm messages which could be rolled up under ‘External Power Supply dropped’.

    1. 1. Achieving Operational Excellence OASYS-AM
    2. 2. <ul><li>With the venue of digital control systems, the number of alarms in control systems has increased </li></ul><ul><li>Cheap sensors and wireless technologies enable putting even more sensors in place </li></ul><ul><li>It is impossible for the human brain to manage more than 6 to 8 items at the time </li></ul><ul><li>The information overload has lead to human errors, unwanted upsets and even fatal incidents </li></ul>This is why UReason has developed OASYS-AM, the next generation alarm management system The challenge Next generation alarm management
    3. 3. Who is ... UReason is specialised in the development and deployment of intelligente alarm management systems UReason developed its own “leading edge” technology, based on many years of experience in alarm handling in different industries UReason is an international company with headquarters in Leiden Next generation alarm management
    4. 4. Next generation alarm management
    5. 5. Which alarm message would you understand better ? <ul><li>“ normal” alarm of a DCS or SCADA </li></ul><ul><li>Low level indication </li></ul><ul><li>Measured value is below a given pre-defined alarm limit </li></ul>Or: <ul><li>Operational Advice. Tells the operator how to solve the problem </li></ul><ul><li>OASYS “ knows ” the engine is connected to the generator providing power to the compressor </li></ul><ul><li>Alarm message and advice enables the operator to avoid the problem (a compressor trip) </li></ul>Next generation alarm management
    6. 6. Which alarm list would you prefer? OASYS-AM Next generation alarm management <ul><li>UReason style of alarm list </li></ul><ul><li>Reduced number of messages </li></ul><ul><li>More explanation upon request </li></ul><ul><li>More comprehensible </li></ul><ul><li>Less annunciation </li></ul><ul><li>Many older alarm </li></ul><ul><li>systems look like this: </li></ul><ul><li>Arbitrary use of colours </li></ul><ul><li>Designed by process engineer, not necessariliy for operators </li></ul><ul><li>Not meant for non-trained users </li></ul>
    7. 7. Why less alarms? <ul><li>Alarm annunciation is the biggest stress factor for operators </li></ul>Source: ASM Consortium Stress is the main cause for human errors Human errors are the most frequent cause for incidents and upsets Next generation alarm management
    8. 8. Why operational advice? <ul><li>Not enough alarms decrease awareness of the operator and lead to unexpected upsets </li></ul><ul><li>Too many alarms lead to stress and human errors </li></ul>Operational advice increases the quality of the information and reduces the quantity Next generation alarm management consists of finding the right balance between awareness and stress Next generation alarm management
    9. 9. Why OASYS-AM can be classified as a next generation alarm system Next generation alarm management
    10. 10. Advantages of OASYS-AM Increase uptime / reduce downtime Reduce time to repair or maintain Extend life cycle of assets Reduce time to diagnose root cause Minimising the influence of an upset to adjacent business processes Reduce workload of operators Comply to current and future guidelines and/or legislation Avoid hazardous situations and resulting claims and penalties Reduce number of operators Next generation alarm management
    11. 11. Results achieved with OASYS-AM Next generation alarm management
    12. 12. LyondellBasell Overview of the reduction realized, varying between 30% – 65% Next generation alarm management
    13. 13. Beer brewery Reduction number of FTE with 80% , night & week-end unmanned
    14. 14. Northsea Oil & Gas Assets Alarm reduction on 4 platforms between 25% - 60% Achieving Operational Excellence OASYS-AM
    15. 15. Chemical plant Proactive 24x7 information on gas leaks Operators don’t have to do a 12 hours plant inspection Important for keeping licence to operate
    16. 16. More advantages OASYS-AM provides the possibility to optimise the entire process/workflow OASYS-AM supplies engineering and play-back facility OASYS-AM is based on EEMUA Publication 191 Next generation alarm management
    17. 17. The customers of UReason
    18. 18. Next generation alarm management
    19. 19. <ul><li>OASYS-AM software runs in combination with different DCS, PLC, SCADA and other systems (system independent) </li></ul><ul><li>OASYS-AM is “clean to install ”. No entries in registries , no change in DCS or SCADA software hence no interference with these systems and no dependency on upgrades </li></ul><ul><li>OASYS-AM can be updated with new rules without stopping it </li></ul><ul><li>UReason OASYS-AM Service Level Agreement and Product Support available (releases, new versions, service and fixing, consultancy support, telephone user support, user area website, etc.) </li></ul>Deployment Next generation alarm management
