In high-hazard industries, small assumptions can lead to major consequences. After unpacking failure rates in our first session, Cenosco returns with the second webinar in our SIS mastery series, this time focusing on Mission Time and Useful Life, two critical (and often misunderstood) parameters in Safety Instrumented Function (SIF) design.
Led by Cenosco’s SIS domain expert Pieter Poldervaart, this session goes beyond theory. You’ll learn how these parameters directly influence your Probability of Failure on Demand (PFD) calculations and how to apply them correctly without falling into the trap of overly optimistic or unnecessarily conservative assumptions.
With a practical, real-world approach grounded in IEC 61511, this webinar equips you to design safer systems and make defensible decisions.
This is the second installment in our ongoing SIS webinar series, where we break down every critical input into SIF PFD calculations, giving you clarity where the industry often relies on assumptions.
Porque é que deve participar?
Because getting SIF design “almost right” is not enough.
Mission Time and Useful Life are often oversimplified, or worse, ignored, in PFD calculations. The ‘SIF Design: Mission Time & Useful Life Explained’ webinar will help you understand how to treat them correctly, ensuring your safety functions perform as intended throughout their lifecycle.
Expect to walk away with:
- A clear understanding of how Mission Time and Useful Life impact PFD outcomes
- Practical guidance on applying these parameters in real SIF designs
- Insights aligned with IEC 61511 requirements
- Real-life examples that reflect actual plant conditions
- The confidence to justify your design decisions to auditors, stakeholders, and regulators
A quem se destina este webinar?
