instrumentation & control engineering

HERVE BARON

Engineering Training

Welcome to this presentation.

It is part of a suite of Engineering training modules.

It shows the activities and deliverables of the Instrumentation & Control discipline.

Comments are most welcome (herve.baron@gmail.com), which I will incorporate for the benefit of all.

Please download this file so that you can see my trainer’s notes in the top left corner – latest Acrobat Pro feature.

Emergency shutdown (ESD) SIL study

Have you heard about SIL studies? What does it mean?

What does SIL, SIF and SIS mean?

Terms defined in ANSI/ISA-84.00.01-2004 (IEC 61511-1) Functional Safety: Safety Instrumented Systems for the Process Industry Sector

SIF: Safety Instrumented Function

SIS: Safety Instrumented System: Sensor + logic solver + final element

SIL: Safety Integrity Level: Level used for specifying the safety integrity requirement of SIFs. There are 4 levels:

HERVE BARON

Step 1: SIL Determination, “assignment workshop”

Identification of Instrumented Interlocks on the P&IDs = inventory of Safety Instrumented Function (SIF)

For each SIF: • Qualitative evaluation of consequences if the event the SIF is

designed to safeguard from • Qualitative evaluation of the likelihood of the event • Determination of risk level (likelihood * consequence) and

resulting SIF required performance (SIL level)

Deliverable: SIL assignment logsheet / worksheets

LIKELIHOOD CATEGORY DEFINITION POTENTIAL FREQUENCY

A Possibility of repeated incidents 20 or more times per Facility life B Possibility of isolated incidents 5 times per Facility life C Possibility of occurring sometime Once in Facility life D Not likely to occur Once every 10 Facility lives E Practically impossible Once every 100 Facility lives

CONSIDERATIONS CONSEQUENCE CATEGORY Health/Safety Public Disruption Environmental Impact Financial Impact

Deliverable: SIL assignment logsheet / worksheets

Summary:

What is the second step of the SIL?

SIL Study

Step 2: calculations and recommendation

SIS Performance Verification

Evaluate the performance of each SIF, based on device selection, architecture, voting, testing etc.

Compare to required SIL level and specify modifications to the SIF design (device selection, component redundancy) or testing intervals

Deliverable: SIS Performance Verification Results and recommendations
