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.

Testimonials
I finally found a course with a practical truth approach. I needed to learn how to calculate SIL according to IEC-61511. The SILcet calculation tool gives a lot of respect at first but it is very easy to use after doing the exercises.
Interesting. It is a good course if you are looking to learn how to design safety functions. What I liked the most was the support of the instructor with very good technical knowledge. It is not a risk analysis course but design of SIFs and verification.
The truth is that for me, who knew very generic SIL concepts from module 1 to 3, the course has solved all my doubts about how to design and validate SIL in my company. SILcet is a simple tool to use and at the same time as powerful as other tools on the market that are much more expensive.
The course is very interesting and practical. It has really exposed me to the world of functional safety and how to apply the data to SIF design. Now I am able to read design document and understand the content. What is more, I now have the knowledge to make meaningful contributions during project design meetings. Honestly speaking, the benefits are more than the price I paid because other training providers charge more and students don’t get much from their training. The SILcet tool is the most important of this training because without it, it is difficult for engineers to design SIF as they have to pay huge amount for software like Exsilentia, Safeguard Profiler etc. Excellent support received from trainer.
Although all the modules were interesting, I particularly find modules 4, 5, 6 & 7 most interesting as they are very practical and very close to what happens in the industry. If you are serious and ready to learn, you will acquire a lot of practical experience designing SIFs by thoroughly studying those modules. The SILcet tool is an excellent tool as it makes it easier to implement SIF design and also very affordable. A lot of engineers today in the functional safety discipline don’t know how to execute SIL Verification even after attending training because of the lack of access to industry software which are expensive. This tool has made it both practical and realistic to conduct SIF design easily and to visualize with a high degree of certainty how the various elements contribute to the overall PFDavg, MTTFS and cost.
