The STIER© software is intended to guide the user through the step-by-step process described in our Equipment Reliability Planning (ERP) work process. It also captures and store equipment information, scenarios, decisions, economics and inspection/maintenance plans and costs developed as a part of the assessment process, and generates multi-level reports from unit level through individual equipment items.
The software—as currently configured—addresses fixed equipment, piping, and rotating equipment; with plans to implement modules for electrical and instrumentation items.
Features and Benefits
- Provides a structured risk based approach for making decisions on inspection, maintenance, repairs and condition monitoring of various equipment types in a process plant. The risks assessed by the tool include Safety, Health, Environmental and Financial Impact for equipment and their associated facilities using industry Best Practices.
- Format facilitates on-line documentation of inputs from cross-functional teams (Operations, Technical, Maintenance and Subject Matter Experts).
- Generates both concise summary reports and detailed equipment reports which describe inspection and maintenance tasks and a cost basis for developing Reliability and Maintenance budgets.
- Task lists reports that are suitable for uploading into Computerized Maintenance Management Systems (CMMS).
- The tool complies with the API RP 580 Risk-Based Inspection and ASME PCC-3 Inspection Planning Using Risk-Based Methods.
- The software includes a Knowledge Base with specific guidance on identifying damage (degradation) mechanisms, failure modes and assessing probabilities of occurrence. Input to the Knowledge Base is provided by recognized Industry Experts.
- The risk-based benefit / cost functionality enables users to develop and justify tasks that are “value added” for improving safety and reliability and minimizing unplanned outages.
- Provides a systematic methodology for evaluating unmitigated risks, mitigation measures and establishing risk thresholds for continued safe and reliable operation.
The STIER Tool GUI allows the user to view existing or add new company, unit, assessment and equipment data.
For an equipment item, the user then enters or imports from Excel the following information:
- Equipment data
- Fluid and contaminant data
- History of repairs, inspections and incidents
- Scenarios, i.e. damage mechanisms and consequences
- Action items, i.e. inspection and maintenance task
- Mitigation plans, shown below
