Design of SIFs and SIL Calculation What to expect from the Course? Understand Learn Benefit Methodology (online course)

Transcription

1 COURSE CONTENT Design of SIFs and SIL Calculation are made with the SILcet tool that allows different design alternatives to be compared. 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 (online course) 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. Alternatives to modernize an existing SIS. 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 Objective 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 Self-directed course in English. Duration (full course of 8 modules): between 21 and 40 hours in 60 days depending on student level (available 24/7). Methodology "learn by doing" Individual Progress. No scheduled sessions Documentation and Tools PDF documents (more than 350 slides), including the practical cases. Excel files (SILcet) with real calculations. SILcet 4.0 Pro license included (6 months) (*) SILcet Manual and detailed document with formulas to calculate PFDavg and MTTFS. More than 40 videos with explanations. Instructor Support. Exercises, evaluation tests and training certificate.
