This book describes the design phase of the SIS safety life cycle as defined in IEC 61511:2016. Starting with a description of the entire safety life cycle process, the authors show how the design steps fit into that process starting with conceptual design through design verification. The book explains the advantages of the performance-based approach to design and provides the theoretical background for the probabilistic calculations that are the foundation of performance verification. The book also explains minimum redundancy concepts and equipment qualification. By providing numerous examples, the authors explain potentially confusing language from IEC 61511 and IEC 61508. Appendices include statistics, probability, failure-rate data tables, and system architectures. Each chapter contains questions and answers similar to those found on professional certification exams for functional safety, which makes the book a valuable resource for those seeking to achieve personnel certification.

Annotation This newly revised best-seller is ideal for instrumentation and control system engineers in the process industries who are responsible for designing, installing, and maintaining safety instrumented systems. Engineers, managers, technicians, and sales professionals employed by end users, engineering firms, systems integrators, and consultants can all benefit from the material presented here. Safety Instrumented Systems: Design, Analysis, and Justification, 2nd Edition addresses the increased realization that today s engineering systems and the computers used to control them are capable of large-scale destruction. When even a single accident could be disastrous, the luxury of learning from experience no longer exists. This book is a practical how-to text on the analysis, design, application and installation of safety instrumented systems.

This book explains the decision-making processes for the management of instrumented protective systems (IPS) throughout a project's life cycle. It uses the new IEC 61511 standard as a basis for the work processes used to achieve safe and reliable process operation. By walking the reader through a project's life cycle, engineering, maintenance, and operations, the information allows users to easily focus on their responsibilities and duties. Using this approach, the book is useful as a primer, guidelines reference, and resource manual. Examples provide the added "real-world" experience applications.

This book clearly explains how to do probabilistic calculations to accomplish SIL verification for safety systems. Starting with a description of the safety lifecycle, the authors show where and how SIL verification fits into the key activities from conceptual design through commissioning.

Engineering responsibility should not require the stimulation that comes in the wake of catastrophe. This caption to an introductory cartoon (each chapter has one) sums up the authors' philosophy that with computer control of complex systems with the potential for large- scale disasters, engineers

Plant Hazard Analysis and Safety Instrumentation Systems is the first book to combine coverage of these two integral aspects of running a chemical processing plant. It helps engineers from various disciplines learn how various analysis techniques, international standards, and instrumentation and controls provide layers of protection for basic process control systems, and how, as a result, overall system reliability, availability, dependability, and maintainability can be increased. This step-by-step guide takes readers through the development of safety instrumented systems, also including discussions on cost impact, basics of statistics, and reliability. Swapan Basu brings more than 35 years of industrial experience to this book, using practical examples to demonstrate concepts. Basu links between the SIS requirements and process hazard analysis in order to complete SIS lifecycle implementation and covers safety analysis and realization in control systems, with up-to-date descriptions of modern concepts, such as SIL, SIS, and Fault Tolerance to name a few. In addition, the book addresses security issues that are particularly important for the programmable systems in modern plants, and discusses, at length, hazardous atmospheres and their impact on electrical enclosures and the use of IS circuits. - Helps the reader identify which hazard analysis method is the most appropriate (covers ALARP, HAZOP, FMEA, LOPA) - Provides tactics on how to implement standards, such as IEC 61508/61511 and ANSI/ISA 84 - Presents information on how to conduct safety analysis and realization in control systems and safety instrumentation
