Maximizing Risk Reduction through Collection and Analysis of Operation & Maintenance Data
Operation & Maintenance Data Collection with SILstat
SILstat™ simplifies the recording of safety critical events during your lifecycle processes, helping validate assumptions made during analysis and design of the SIS. The resulting data helps with optimization of the current SIS or design of a new system.
SILstat™ allows you to be compliant with requirements outlined by the IEC 61511 / ISA 61511 standards and with an OSHA Process Safety Management (PSM) Mechanical Integrity Program.
Aligned with exSILentia version 4, SILstat™ allows you to seamlessly transfer project data creating a Plant Hierarchy and Library that acts as the backbone for your SILstat™ database.
Data Collection
SILstat supports the capture, documentation, and classification of the following life events: Hazardous Events, Device Failures, Proof Tests, scheduled Maintenance activities, and ad hoc Maintenance events.
Data Flow
Much of the required SILstat™ configuration can be built automatically through a simple transfer of exSILentia data. This not only reduces application setup time cost but improves traceability between safety system design and operation and maintenance. After the data is transferred, you will be able to easily configure SILstat™ to fit your needs.
Configuration
exSILentia data is the backbone for your SILstat™ Plant Hierarchy. This provides easy navigation to your Safeguards, Devices, Hazards, and Procedures. Each change to the database is auditable and traceable to the user.
Collection
SILstat™ guides you through a step-by-step workflow for your safety critical events. Users can define workflows for certain events, including mandatory reviews and approvals.
Device Lifecycle
Within SILstat™ , events for each of your devices can be captured. These include Install, Bypass, Replace, Repair, and Remove events. These events will be automatically added to a Device Timeline for easy lifecycle visualization.
Data Evaluation
Capturing operation and maintenance data (events) for plant equipment provides the ability to evaluate the actual risk reduction achieved.
| Level of Actual Risk Reduction Provided | Actions | |
| Protection is adequate | Continue data collection | |
| Protection is inadequate | Process hazard risk is higher than expected or SIF is under designed to protect against the process hazard. return to Analysis phase for redesign and implementation. | |
| Protection is more than adequate | SIF is over-designed to protect against the process hazard or process hazard risk is lower than expected. Allows modification of design practices for future applications and potential for cost savings. | |
