Modules 1-2-3

-Basic concepts, International Standards. What does SIF, SIS, SIL mean? Control System versus Safety Instrumented System

-Types of failures and examples. The importance of diagnostics. Types and examples.

-SIS Life Cycle: Analysis Phase, Design and Implementation Phase, Operation and Maintenance Phase

-Risk concepts and how to reduce them with layers of protection. What is an independent protection layer (IPL)? SIS principle of independence and shared elements. Examples.

-Types of Risk Analysis Techniques. Determination of «SIL» with Risk Graphs. Risk Gap concept, required SIL. Example with Risk Graph.

-Example with Safety Requirements Specification (SRS).

-Most used architectures and examples. Principles of safety system design. Safety versus Availability.

-IEC requirements and key parameters to calculate the SIL. Formulas to calculate PFDavg and MTTFS. Data sources of failure rates.

-Simple example of SIL verification.

Module 4

-Assumptions for the examples (configuration Low/High of the transmitter according to the architecture, online / offline tests, etc.).

-Practical exercises using the SILcet tool:

1-Tank Level (several cases)

2-Vessel under pressure (several cases):

i) undefined sensor type

ii) transmitter vs switch

iii) diversity of elements

iv) credit by comparison

v) bypass impact.

3-Calculate the SIL achieved by the Logic Solver.

-21 general considerations to design the SIS.

-Excel files included: “SILcet with the exercises solved” & Example of Safety Requirements Specification (SRS).

Module 5

-Assumptions for the examples.

-Real practical exercises using the SILcet tool:

  1. Low combustion air flow in Incinerator or Furnace.
  2. Stop of high pressure pumps by partial closure of the suction.
  3. Gas valve closure due to flame loss.
  4. Emergency depressurization in a reactor: action on several lines when the temperature is excessive (Reactor Bed Temperature).
  5. How to solve a SIF with two Logic Solvers (Safety PLCs).
  6. SIF with shared elements (Control System and SIS).
  7. Example with Partial Valve Stroke Test.
  8. Examples with Complex Architectures.

– Excel file included: “SILcet with the exercises solved”.

Module 6

-How to prepare a SIL Verification Report.

-Main document with MS-Word Template.

-Annex of parameters, graphs and results (PFDavg, PFH, MTTFS) generated by SILcet.

-Example of report with the exSILentia tool.

Module 7

Note: Other additional exercises that are delivered resolved to the participants at the end of the course.

-Assumptions for the exercises.

-Real practical exercises using the SILcet tool (in each case there are several possible configurations):

  • Turbine Trip Valve Hydraulic System.
  • High Integrity Pressure Protection System
  • Pressure vessels (different cases).
  • Others: Solutions with high availability, Fire & Gas System, Protection of a Silo.

– Excel file included: “SILcet with the exercises solved”.

Understand what a SIF is and what concepts and parameters are the most influencing its design.

Learn how to design a SIF and calculate and verify the SIL and MTTFS of real Safety Functions in the process industry.

Benefit from Lessons Learned and Best Practices acquired from Major Projects.

Why is it a different course?

  • Because we use a SIL calculation and verification tool developed by us (“SILcet“) that allows us to make a lot of 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 Plus) of SILcet with many of the examples of the course.

Technicians, designers, system integrators and engineers related to Functional Safety and Safety Instrumented Systems (SIS) of the process industry.
It is advisable to have certain knowledge of instrumentation and control.

The objective is to acquire knowledge to understand and design Safety Instrumented Functions (SIF) from a totally practical point of view. To do this, real examples are made with the SILcet tool that allows different design alternatives to be compared.
