TÜV Functional Safety Engineer: IEC 61511 Certification

▸ The TÜV Functional Safety Engineer designation is the benchmark qualification for process sector safety engineers working with Safety Instrumented Systems.

This course gives you a rigorous, exam-grade command of IEC 61511 — the full lifecycle, the calculations, and the documents you will be assessed on.

▸ Important — how FSEng certification actually works

The FS Engineer (TÜV Rheinland) certificate can only be obtained by attending a complete training course from an accredited provider within the TÜV Rheinland Functional Safety Training Program and passing the exam held at the end of that course. Candidates must also hold an engineering degree and have three years' practical experience in functional safety. Sitting the exam alone does not grant the certificate.

This course is not accredited training and cannot certify you.

What it does is get you to that accredited course already competent. The four days become consolidation rather than a first encounter, the calculations are ones you have already rehearsed, and the exam is one you have already sat twice in mock form. It is also a complete standalone reference for practitioners working to IEC 61511 who are not pursuing certification at all.

▸ Calculation-led, not clause recital

Every quantitative topic is worked end to end. PFDavg for 1oo1, 1oo2, 2oo2 and 2oo3 architectures using the simplified equations, including common cause failure beta factor terms. Full SIS PFDavg combining sensor, logic solver and final element subsystems. Proof test interval optimisation. And the calculation errors that cost marks most often.

▸ Course structure — 75 lectures across 12 sections, plus two mock papers

• Foundations — what functional safety is, IEC 61511 structure and scope, its relationship to IEC 61508, key terminology (EUC, SIS, SIF, BPCS), and roles and responsibilities

• Functional Safety Management — Clause 5 requirements, the FSM plan, competency management, functional safety auditing, document control and traceability, and management of change

• Hazard & Risk Assessment — hazard identification, consequence and likelihood, tolerable risk criteria, LOPA methodology, IPL credits and common mistakes, SIL determination by three methods, and a full worked example

• Safety Requirements Specification — why the SRS is the most important document in the lifecycle, mandatory content across safety, system and operational requirements, review and approval, and the deficiencies examiners test most

• SIS Design — architecture principles, Clause 11 architectural constraints, redundancy configurations, common cause failure and beta factor mitigation, sensor selection and proven-in-use, logic solver selection including TMR and safety PLCs, final elements, and independence from the BPCS

• SIL Verification — failure rate terminology, PFDavg by architecture, combining subsystems, proof test interval optimisation, a full worked verification, and common calculation errors

• Installation, Commissioning & Validation — FAT, SAT and loop checking, Clause 14 validation, the four Functional Safety Assessment phases, pre-startup safety review, and commissioning records

• Operation, Maintenance & Proof Testing — Clause 16 obligations, proof test principles and procedures for each subsystem, partial stroke testing, bypass and inhibit management, and demand rate monitoring

• Modification, Decommissioning & CHAZOP — SIS modification under management of change, software management, Clause 18 decommissioning, CHAZOP methodology and a practical walkthrough

• Exam Preparation — exam format and marking, high-frequency topics, four fully worked scenarios covering risk assessment, SRS deficiency identification, SIL verification and operational MOC, plus a revision framework

• LOPA & Quantitative Risk Assessment — Deep Dive — initiating event frequency data sources, advanced IPL credit edge cases, QRA versus LOPA, non-standard scenarios, and a worked advanced case study

• Advanced SIL Verification — Markov & Fault Tree — the limits of the simplified equations, Markov modelling and state diagrams, fault tree analysis for SIS, staggered proof testing, and a full worked Markov model

▸ Six downloadable resources built for real projects

• LOPA Excel Template — pre-built worksheet with worked example, usable on live studies

• SIL Verification Excel Template — PFDavg calculator for all four architectures with CCF beta factor

• SRS Checklist — Clause 10 completeness checklist, one per SIF

• IEC 61511 Clause Navigation Card — every key clause mapped to lifecycle phase, colour-coded and designed for open-book use

• PFDavg Formula Reference Card — every simplified equation on one laminate-format page

• Exam Scenario Practice Pack — four full FSEng-style scenarios with model answers and mark schemes

▸ What you get

• 13 hours of structured video across 75 lectures and twelve sections

• Two full 70-question mock examination papers — timed, scored and retakeable

• Six downloadable templates, checklists and reference cards

• Four worked exam scenarios with model answers and marking schemes

• Advanced modules on quantitative risk assessment, Markov modelling and fault tree analysis

• Lifetime access, mobile and TV access, and a certificate of completion

• Udemy's 30-day money-back guarantee

▸ No prior IEC 61511 or functional safety knowledge is assumed — the framework and terminology are established from first principles before any advanced content. Any engineering or technical background is enough to follow it, and every calculation is worked step by step with a calculator. No software required.

Built by a practising engineer with over fifteen years delivering SIS and functional safety on oil, gas and energy projects — including SIL determinations, safety requirements specifications, verification calculations and functional safety assessments on active major hazard installations.

If you are preparing for accredited FSEng training, or you work to IEC 61511 and need the lifecycle, the calculations and the documents at command level, this is where to build that.
