The ANSI SP 84 (formerly ISA 84.01) “Application of Safety Instrumented Systems for the Process Industries” standard requires that companies assign a target safety integrity level (SIL) for all safety instrumented systems (SIS) applications. The assignment of the target SIL is a decision requiring the extension of the process hazards analysis (PHA). The assignment is based on the amount of risk reduction that is necessary to mitigate the risk associated with the process to an acceptable level. All of the SIS design, operation, and maintenance choices must then be verified against the target SIL.

This course covers the systematic method for selecting safety integrity levels (SILs) for safety instrumented systems (SIS). Although numerous methods have been proposed and adopted by industry, layer of protection analysis (LOPA) is rapidly becoming the most frequently used method. Its popularity stems from its ease of use and the accuracy of the results it provides. LOPA accounts for most existing layers of protection, more than any other method. With this proper accounting, the SIS is neither overdesigned nor overpriced. The LOPA method ensures that users achieve the maximum return on their risk reduction investments.

The result of using poor methods to select SILs is typically either an overdesigned or an under designed safety instrumented system. The risk analysis that forms the basis for SIL selection, however, can be greatly improved. This will provide the user with more accurate results so formerly inflated requirements can be relaxed, which will in turn lower not only the initial installation costs, but the cost of ongoing maintenance.

Much of the material in this course is based on the application of the safety life cycle as it is described in the international standards ANSI SP 84 (formerly ISA 84.01) “Application of Safety Instrumented Systems for the Process Industries” and EN/IEC 61508/61511. This course expands upon the framework developed in these standards. In addition to describing the tasks that users should perform during the safety life cycle, this course also provides detailed procedures for accomplishing these tasks. These procedures are based on risk analysis and reliability engineering principles from a variety of disciplines.

Upon the successful completion of this course, each participant will be able to:-

• Apply and gain a good working knowledge on the standards related to safety integrity level (SIL) which includes IEC 61508, IEC 61511 and ISA S84

• Discuss the safety life cycle including its phases and the safety requirement specification for safety integrity level (SIL)

• Integrate risk reduction and risk management and identify the proper hazard analysis for HAZOP study, fault tree analysis, event tree analysis and failure mode and effects analysis (FMEA)

• Select sensors and final elements, determine the probable causes of failure and list the general requirements for fail safe operations

• Illustrate a detailed explanation on safety instrumented systems including its safety architecture and major systems and explain how SIF fits with SIS and SIL

• Employ the SIL application for safety instrumented level, compare low demand mode and continuous mode and determine the probability of failure on demand

• Develop a proper SIL determination by using the ALARP, semi quantitative, safety layer matrix, risk graph and LOPA methods

• Carryout a detailed SIL verification and validation, provide a SIS documentation schedule and risk reduction diagrams and demonstrate proof testing

• Explain the certified software models for safety software, development life cycle and asset management software

• Illustrate the operation, planning and maintenance of SIS and recognize the need for smart Safety Instrumented Systems, intelligent field devices, digital communications and smart logic solvers

• Cite practical examples of risk graph, risk matrix and multiple layers of protection

This course provides an overview of all significant aspects and considerations of safety integrity level (SIL) determination and verification for senior process control engineers, senior control systems engineers, process control engineers, process engineers, control systems engineers, reliability and integrity engineers as well as safety engineers, professionals and regulators.

Internationally recognized certificates will be issued to all participants of the course who completed a minimum of 80% of the total tuition hours.
