Description:
"An excellent one day overview of a complex and diverse subject." ~Peter Skipp, Engineering Manager
There are many different ways of designing a safety instrumented system (SIS). Questions like these are being asked by users and engineering firms alike:
- Which technology should be used (electric, electronic, or programmable)?
- What level of redundancy is appropriate (single, dual, or triple)?
- How often should systems be tested (monthly, quarterly, yearly, or once per shutdown)?
- What about field devices (technology, level of redundancy, and test intervals)?
Debates continue as to how one even makes these choices (past experience, qualitative judgment, quantitative analysis, etc.). This seminar will cover the basics of what needs to be done in the design and selection of safety systems.
You will be able to:
- Recognize the design basis of recent standards, guidelines, and recommended practices
- Describe the difference between process control and safety control
- Describe the lifecycle set of activities that are necessary to design, implement, and maintain safety systems
- Discuss the basics of evaluating process risk levels
- Discuss the basics of determining Safety Integrity Levels (SILs)
- Describe the failure modes of safety systems
- Recognize the real impact of redundancy
- Describe the pros and cons of various logic system technologies
- Explain the impact of field devices on system performance
- Identify documentation requirements
You will cover:
- Introduction: What is a Safety System? | Danger of Overconfidence and Complacency | Lessons Learned from Past Accidents
- Guidelines and Standards: ANSI/ISA | IEC
- General SIS Design Considerations: Design Life Cycle | Independent Safety Layers
- Hazard and Risk Assessment: Hazard Identification | Risk Assessment | Determining SILs | Layer of Protection Analysis (LOPA)
- Failure Modes: Safe vs. Dangerous | Redundancy Issues
- System Technologies: Relay | Microprocessor | Field Devices | Certification vs. Prior Use
- Operation and Maintenance: Installation | Testing | Management of Change
