Certified TUV SudSIL Verification and Determination Training
- Course Objectives
The course will equip participants with the knowledge for understanding and mastering the application, principles and requirements of verification and validation in accordance with IEC 61508 and IEC 61511.
Agenda
The course will provide an introduction to the functional safety standards and the concept of the functional safety lifecycle followed by developing the safety requirements specification (SRS) and preparing for the system validation. Participants will then be introduced to the concepts of average probability of failure on demand (PFDavg), average frequency of dangerous failure (PFH), safe failure fraction, hardware fault tolerance, proven in use, failure modes, reliability, diversity, separation and the influence of common cause with in depth instruction in the requirements for verification explaining the different methods for calculating the PFD and PFH including extracting data from reports to calculate safe failure fraction and The topics covered are: - IEC 61508 and IEC 61511 background
- Functional Safety Management and the application of the FS lifecycle
- SIS Safety Requirements Specification
- Common cause failures and influence on reliability
- Safe Failure Fraction and Hardware Fault Tolerance
- Understanding Demand Modes, Failures and failure modes
- Selection of Components and Subsystems including Proven in use
- Understanding technical information / certificates and reports
- Reliability data, interpreting failure data and applying Confidence levels
- Partial Closure Testing
- Validation Planning and reporting
- Practical Exercises
- Case Studies with typical findings and issues
- Who Should Attend?
Instrument Engineers, Process Engineers and Safety Engineers as well as Operating and Maintenance personnel who are involved in any of the lifecycle phases for safety instrumented systems from hazard and risk assessment, shut down system/fire and gas systems design to testing maintenance.
SIL Determination using LOPA and Risk Graph ( 2 Days ) ( COURSE Code FS004)
All plant operators and project engineering teams need to consider instrument protection systems as a part of the overall health, safety and environmental protection facilities. Safety and environmental risks need to be reduced
to a tolerable level as required by national regulatory authorities and commercial risks reduced to meet business needs
In times of rising costs for materials and resources, risk reduction must be handled cost effectively, incorrect determination of integrity requirements can mean that costs escalate to double or even triple the original budget. If the process is managed following the IEC 61511 safety lifecycle model then only moderate changes to existing company safety system practices, with relatively minor costs may be required. More importantly, if the work is done well, the safety lifecycle process of “plan, implement, and review” significantly reduces wasteful over-design of instrument protection systems, as well as limiting unsafe under-design.
This 3 day comprehensive workshop: Safety Integrity Level Determination will equip delegates with a solid fundamental knowledge of the principles which they can apply immediately by getting a practical understanding of the key requirements of SIL Determination using the methods in IEC 61511
Course Objectives
The objectives of the workshop are to equip participants to:
▪ Understand the principles of ALARP and risk assessment.
▪ Understand the principles of Risk Graph and LOPA.
▪ Understand the tolerable risk targets and how to set them
▪ Understand how to set up and record SIL Determination studies.
▪ Use the HAZOP to identify cause and consequence scenarios
▪ Identify Safety, Asset and Environmental consequences
▪ Break down the causes and apply failure and frequency data.
▪ Identify Independent protection layers and apply the associated rules.
▪ Understand prevention and mitigation protection layers.
▪ Assign values to protection layers and avoiding common cause issues.
▪ Use conditional modifiers and enabling conditions / events.
▪ Take part in Risk Graph LOPA risk assessment.
The workshop will be based around a case study and a number of practical team exercises to stimulate a realistic risk assessment experience.
