Why Functional Safety Professionals Choose This IEC 61511 Course

Focus completely on Safety Instrumented Systems (SIS) and Safety Instrumented Functions (SIFs) in the process industry.
Learn exactly what IEC 61511 requires for SIL-compliant SIFs — from HAZOP/LOPA through design, PFD calculations, and operation.
Work through live case studies, group exercises, and exam-style questions with an expert trainer.
Prepare directly for FS Specialist, FS Engineer (TÜV), and FS Professional (TÜV) — in one integrated live program.
Learn with a trainer who has certified hundreds of SIS, subsystems, and devices and supported end users, EPCs, and integrators worldwide.

What You’ll Be Able to Do

Explain functional safety according to IEC 61511 and how it differs from and relates to IEC 61508.
Apply the functional safety lifecycle to SIS: from hazard analysis and SIF specification to operation, maintenance, and modification.
Use Functional Safety Management (FSM) concepts such as lifecycle planning, competence, verification, validation, assessment, audits, and documentation.
Understand how end users use HAZOP and LOPA to identify SIFs and determine required SIL and Risk Reduction Factors.
Develop and review Safety Requirements Specifications (SRS) for SIS and SIFs, including all key content required by IEC 61511.
Apply hardware concepts such as Type A/B, voting, redundancy, hardware fault tolerance (HFT), safe failure fraction (SFF), and architectural constraints.
Differentiate diagnostic tests and proof tests, select test intervals, and understand their impact on PFD and availability.
Perform and interpret PFD calculations using simplified equations and basic reliability modelling to support SIL verification.
Handle application program requirements (FVL, LVL, FPL), V-model testing, and software systematic capability.
Assess certificates, prior use and proven-in-use claims for devices, subsystems, and SIS solutions.
Plan for operation, maintenance, repair, modification, and bypass of SIFs without losing SIL compliance.
Confidently sit the FS Specialist and TÜV exams and start your pathway to Professional, Expert and Master certification.

Who This Course Is For

Professionals in the process industry who work with or around Safety Instrumented Systems, including:

SIS and SIF engineers responsible for design and implementation of safety instrumented systems.
Process, control, and automation engineers involved in HAZOP, LOPA, and protection layer design.
Functional Safety engineers and managers who must demonstrate IEC 61511 compliance to clients, regulators, and auditors.
EPC and system integrator teams designing and delivering SIS for oil & gas, chemicals, petrochemicals, and related sectors.
End user engineers and operators who operate, maintain, and modify existing SIS and SIFs.
Consultants, assessors, and certifiers who need a solid, practical understanding of IEC 61511 requirements.

Requirements & Recommended Background

Bring an open mind and willingness to learn.
~6 years of experience in the process industry is recommended for certification titles.
Basic knowledge of functional safety and SIFs is helpful but not required — the course starts from fundamentals.
Time reserved to participate fully in the live sessions and complete the exam.

If IEC 61511 appears in your contracts, audits, or plant standards, this program is designed for you.

How the Live Training Works

Multi-day live training, plus an integrated exam.

Live Online: Instructor-led sessions via Teams/Zoom with real-time Q&A, polls, and group work.
In-Person: Classroom-style training with workshops, discussion, and hands-on case exercises.
Structured agenda: Each day covers specific IEC 61511 topics, from fundamentals and lifecycle to hardware, PFD, and operation.
Exercises & examples: Worked examples and case studies showing real SIS and SIF challenges in the process industry.
Exam preparation: Exam-style questions and review throughout the course so you know what to expect.
Exam: The primary exam session is planned on the final course day or immediately after (details provided in your joining instructions).

After the course you keep access to the digital training materials and selected resources, so you can revisit key topics when preparing for audits, projects, or certification upgrades.

Prefer a flexible, study-when-you-want format? The same program is also available as a self-study eLearning course .

What do current students say about this course?

"This course has accelerated my development in the world of functional safety and has been a great aide in my day-to-day work. It could do the same for my colleagues." – Ashley James, United Kingdom

"It was a very educational course and I hope to really enjoy the benefits of this in the future. The trainer was very competent and knows what he is talking about. Every colleague should follow this course, if only it was to understand FSM better." – M. de Kok, Rütgers Resins, Netherlands

"Trainer clearly explained the SIL concepts as they apply to SIS and I feel that I learned something really valuable for my job and career." – R. Saravannan, Petronash, UAE

"While working in oil & gas EPC industry, we come across the requirement of functional safety in all projects and proposals. Implementing functional safety has a cost. If it is not estimated correctly during the proposal stage, it may have serious financial implications during execution. So every engineer working in our industry should have training in functional safety.

Thank you for the great training! I learnt a lot from it and hope that it will help me perform better in my profession." – Rajadwid Goon, Petrofac, Sharjah

"Amazing training. Gained a lot of knowledge on how to deal with functional safety." – G. de Deckere, Dow Benelux, Netherlands
