Safety Integrity Level Assessment for Oil and Gas Assets
Workshop Overview
The Occupational Safety and Health Administration (OSHA) warrants that the design and implementation of a safety system meets good engineering practice. A Safety Instrumented System (SIS) is one of the most important layers of protection against accidents and hazards in the hydrocarbon process industry.
More importantly, Safety Integrity Levels (SIL) defines safety performance criteria for Safety Instrumented System. The determination of the Safety Integrity Level (SIL) required for the Safety Instrumented System (SIS) will determine the configuration of the latter to meet the required integrity level, and in turn improve the reliability of the system.
In order to conduct a SIL analysis, a combination of technical documentation including, Piping & Instrumentation Diagrams (P&ID), Cause and Effect charts, safety studies/documentation review (HAZOP, QRA, Firefighting and detection system data) and economical parameters (equipment cost, product and raw material costs) are required. This will lead to the identification of an initial risk level in terms of personnel safety, environmental loss, commercial impact.
By attending this course, participants will be able to strengthen their knowledge about Safety Integrity Levels and to better implement them at work.
Workshop Outline
Benefit of Attending this Workshop
- Hazard and Risk Assessment: Begin by conducting a hazard and risk assessment to identify potential hazards, assess their likelihood and consequences, and determine the overall risk. This forms the basis for determining the appropriate safety measures.
- Safety Instrumented Functions (SIFs) Identification: Identify the specific safety instrumented functions that are required to mitigate the identified hazards. A safety instrumented function is a specific control action taken by the safety instrumented system to reduce risk.
- Determining SIL Requirements: Based on the risk assessment, assign a target SIL to each safety instrumented function. SIL levels range from SIL 1 (lowest) to SIL 4 (highest). The assigned SIL reflects the desired risk reduction and safety performance.
- SIL Verification and Validation: Determine whether the existing safety instrumented systems meet the required SIL levels. This involves verifying and validating the design, performance, and reliability of the safety instrumented systems.
- SIL Assessment Techniques: Various techniques are used to assess the safety instrumented systems and determine if they meet the required SIL. These techniques include fault tree analysis (FTA), failure modes and effects analysis (FMEA), and reliability analysis.
- Safety Instrumented System Design: Design or modify the safety instrumented system to ensure that it meets the required SIL. This involves selecting appropriate sensors, logic solvers, final elements, and redundancy configurations.
- Verification and Validation of Design: Verify and validate the design of the safety instrumented system to ensure that it meets the requirements for the assigned SIL. This may involve simulation, testing, and analysis.
- Documentation and Reporting: Document all findings, decisions, and analysis results. This documentation is important for regulatory compliance, auditing, and ongoing maintenance of the safety instrumented systems.
- Operation and Maintenance: Regularly monitor, test, and maintain the safety instrumented systems to ensure they continue to meet the required SIL and perform as intended.
