Functional Safety Training Course

SIFs Design and calculation of SIL

This training course has a different design and approach than other courses. The standard course is focused on the design of the SIF (Safety Instrumented Function), comparing different alternatives of cost versus technical solution according to IEC-61508.

Why is it a different course?
  • Because we use a SIL calculation and verification tool developed by us (“SILcet“) that allows us to make real examples. This is impossible to perform in most functional safety courses due to the complexity of calculations when dealing with real cases.
  • We provide a free license (Pro 1) of SILcet to each of the participants with many of the examples of the course.
  • It is a modular course whose contents can be adapted to the needs of the client (introduction to SIL, factors that most influence the probability of failure and how to reduce it, parameters that do not appear in the typical equations of PFDavg, how to modernize old safety systems by comparing alternatives of cost versus technical solution, how to solve complex architectures, etc.)
  • The course can be adapted to the real cases used by the client, including examples, designs and comparison of safety functions (SIF).

The standard functional safety course focuses on the Design, Modification and Verification phases of the safety life cycle.

Examples of Safety Functions (SIF) designed in the course:
  • Gas burner train in a Heat Recovery Boiler (HRSG).
  • ACTUATOR Subsystem: Hydraulic system of the turbine trip valve.
  • High Integrity Pressure Protection System (HIPPS).
  • Pressure vessel protection by acting on the redundant venting system and the compressor.
  • Solutions for high availability SIFs.
  • Fire & Gas System (Sensor Subsystem with multiple detectors, push-button and pressure transmitters, Actuator Subsystem with pumping system, valves, sound alarms and DO to the ESD of the plant).
  • Shutting-off multiple streams to a pressure vessel.
  • Upgrade of existing SIS: Possible solutions comparing cost, safety and availability.
  • Example about the impact of the use of bypasses in the SIF.
  • Other: Silo protection, tank level, SIF with diverse components, SIFs with external diagnostics, etc.
