2 Agenda Alarm Management Effective best practices How can Honeywell tools help? Roadmap Next steps into operations management Effective best practices How can Honeywell tools help? Roadmap Questions 3

3 What is Alarm Management? Process by which alarms are engineered, monitored and managed to ensure safe, reliable operations 4

4 Phase 1 Phase 2 Phase 3 Phase 4 Real results from a customer the approach Bad actor clean up Rationalization Reprioritize Rename Consolidate Document Revisit Alarm Limits No action, No alarm Smart Alarming Shelving First out alarming Mode dependant suppression Offline suppression ASM Graphics S?

8 Operator best practice shift review Review Standing Alarm Report 9

9 Operator best practice shift review Review safety related alarms and actions 10

10 Operator best practice shift review Review shelved alarms 11

11 Weekly Maintenance / Operation Meeting Review Chattering Alarm Report Assign responsibility Discuss repeat offenders on the list 12

12 Weekly Maintenance/Operation Meeting Review Most Frequent Alarms Report Assign responsibility Discuss repeat offenders on the list 13

13 Control Engineer best practice Review Most Frequent Interventions and Intervention Count Over Time Tuning issues Valve stiction Exceeding output limits Control design 14

14 Control Engineer best practice Review what the operator is changing 15

15 HAZOPs, LOPAs & Incident Investigations Number one cause of alarms after a rationalization Teams consist of the resources required for rationalization Topics covered during review Causes Consequences Alarm required Topics needed to be added Corrective actions Severity Priority 16

16 Process Engineer best practice Review alarm rates looking for: Alarm rate changes during product changes Alarm rate changes during shift change 17

17 Process Engineer best practice Review alarm rates looking for: Alarm rate changes during product changes Alarm rate changes during shift change Oscillations 18

18 Summary Initiatives require a systematic approach Alarm management is ongoing Can improve reliability Make part of culture Assign accountability Identify goals and implement methods Tools necessary to achieve the results Incorporate alarm management tasks into workflow PHILOSOPHY IDENTIFICATION RATIONALIZATION DETAILED DESIGN IMPLEMENTATION OPERATION MAINTENANCE MANAGEMENT OF CHANGE MONITORING & ASSESMENT AUDIT ANSI/ISA Alarm Management Lifecycle 19

19 What s next? Operations Management! Alarms protect equipment and personnel Operations Management adds protection for efficiency and profitability Difficult without a healthy alarm system and associated work processes Unplanned Downtime Safety Technology Costs / Effort Production Dependability 21

20 Operations management best practices Communication Know your limits and plan Capture deviations and context Capture operator observations Effective shift handover 22

21 Know your limits and plan Operators Specialists Capture Limits Design, Corrosion, Environmental, Safety, Alarms, etc. 23

22 Know your limits and plan Limit Repository Operators Specialists Design, Corrosion, Environmental, Safety, etc. Capture Limits 24

23 Know your limits and plan Planners Plan Operators Specialists Validate Design, Corrosion, Environmental, Safety, etc. Capture Limits 25

24 Know your limits and plan Planners Operating Instructions Plan Operators Specialists Validate Design, Corrosion, Environmental, Safety, etc. Capture Limits 26

25 Capture deviations and context Planners Plan Operators Specialists Validate Monitor Design, Corrosion, Environmental, Safety, etc. Capture Limits 27

26 Capture deviations and context Planners Intuition Operations Monitoring Plan Operators Specialists Validate Monitor Design, Corrosion, Environmental, Safety, etc. Capture Limits 28

27 Capture operator observations Gain context not found in event journals for investigation activities Satisfy regulatory requirements Knowledge capture Supports an effective shift handover 29

28 Effective shift handover The most common causes of incidents related to shift handover include poor logbook design and poorly conducted shift handovers. Approximately 80% of industrial operations lack a structured approach to shift handovers In 1988, a fire and explosion on the Piper Alpha offshore platform was attributed to poorly documented valve status. A fire and explosion at the BP refinery in Texas City, TX, in 2005 resulted from the failure to log shift startup procedure which, in turn, led to a flammable liquid overfill condition. 30

29 Effective shift handover Reduces risk that critical information is not communicated during shift changes Ensures accurate and consistent understanding of the plant situation is shared from shift to shift 31

30 Summary Alarm management is imperative Operations management builds on your alarm management investment Improves uptime Improves reliability and production dependability Increases safety Reduces cost/effort from technology staff to achieve with home built tools Best practices and effective tools deliver results 32
