Risk | Type of IOW | IOW guidance/Action |
High | Critical | IOW’s Required - Limits and durations established on all IOW process parameters for monitoring; IOW’s are alarmed/alerted and SME’s are notified of exceedances; Operations take urgent predetermined action to return process to normal operation. If exceed, could lead to rapid deterioration of process equipment and need an immediate action. |
Medium High | Critical or Standard | IOW’s Required - Limits and durations established on all IOW process parameters for monitoring; IOW’s are alarmed/alerted and SME’s are notified of exceedances; Operations take predetermined action to return process to normal operation |
Medium | Standard or Informational | IOW information Limit (IIL) identified - IOW’s identified suggested limits specified for each IOW; Operations and SME’s are alerted/notified of exceedances; Troubleshooting initiated with planned adjustments to operations, inspection/maintenance developed. If exceeded over a specific time frame, could cause increased of corrosion rate and need to identity the time to reduce the corrosion rate by a chemical injection etc. |
Low | Informational | IOW information Limit (IIL) suggested - Normal operating parameters identified for analysis; Parameters tracked and trended by SME to determine long-term effects on equipment reliability. Generally to predict the long term integrity of equipment, do not typically require operational responses but maybe utilized to assess fufure repair during turnaround and shutdown frequencies. |
