Design of SIFs and SIL Calculation (version v2)
Design of Safety Instrumented Functions and
verification of SIL and MTTFS based on practical
examples of safety functions in the process
industry. Comparison of different designs and
generation of reports. Most important parts of the
Safety Instrumented System Life Cycle.
Who is it for?
Students, 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.
Course Objetive
The objective is to acquire knowledge to understand
and design Safety Instrumented Functions (SIF) from a
totally practical point of view. For this, all the concepts
on Functional Safety are reviewed, as well as the main
parameters are explained in detail. Real examples are
made with the SILcet tool that allows to calculate the
SIL based on the three requirements of the IEC-
61511/61508 Standard, as well as compare different
design alternatives.
What to expect from the Course
Understand what a SIF is and what concepts and parameters are the most influencing its design.
Learn how to design a SIF and calculate the SIL and MTTFS of real Safety Functions in the process industry.
Benefit from Lessons Learned and Best Practices acquired from Major Projects.
Methodology
Course in English
Duration: 16 to 30 hours (depends on participant experience). Free access to virtual campus “Schoology” 24/7, during 60 days.
Individual Progress. Self-paced training.
Methodology "learn by doing" with many practical examples.
Note: Participants with PC can perform the exercises with the SILcet tool included in the course.
Documentation and Tools
PDF documents with slides of the course modules.
Excel files (SILcet) with the actual calculations of the
practical examples of the course.
License SILcet Pro Plus included (6 months).
SILcet User Manual and detailed document on the
formulas for calculating PFDavg and MTTFS.
Videos with explanations.
Instructor Support.
Exercises, evaluation tests & training certificate.
Note: students can download all documentation except videos.
