Case Studies in the Form of Exercises and Examples
Chapter 11 is an exercise involving SIL targeting for a pressure let-down system. The design is then compared with the target and improvements are evaluated and subjected to ALARP criteria. The answers are provided in Appendix 5.
Chapter 12 is a typical assessment report on a burner control system. The reader can compare and critique this, having read the earlier chapters of this book.
Chapter 13 presents a number of rather different SIL targeting examples.
Chapter 14 is a purely hypothetical proposal for a rail train braking system.
Chapter 15 summarizes some Technis work on helicopter statistics and risk assessments.
Chapter 16 contains case studies relating to tidal gates.
These case studies address the four quantitative aspects of IEC 61508:
SIL Targeting
Random Hardware Failures
Safe Failure Fraction
ALARP.
