Length: 1 day
CEU Credits: 0.7
Course Hours: 8:00 a.m.–4:00 p.m.
(Except Morristown, NJ location classes are 9:00 a.m.–5:00 p.m. and Columbia, IL location is 8:30 a.m.–4:30 p.m.)

Description:

This course provides an introduction to basic reliability engineering focused on safety integrity level evaluation of control systems. The entire evaluation process is introduced including safety instrumented function identification, PFD avg calculation methods, failure rate data, and documentation requirements.

You will be able to:

• Understand basic reliability and safety engineering terms
• Do simple SIL verification calculations
• Identify sources for failure rate data
• Understand what engineering tools are available to do advanced SIL calculations

You will cover:

• Safety Life Cycle:  ANSI/ISA84.01 Safety Lifecycle | Safety Lifecycle Purposes and Benefits | Terms and Abbreviations | Reliability and Safety Analysis as a design verification tool
  •
• Rules of Probability:  Probability is | Events | Multiplication | Addition | Counting | Examples
• Safety/Reliability Basics: Reliability/Availability | Mean time to failure MTTF | Mean time to restore MTTR | Mean time between failures MTBF | Failure modes | Measures of safety
• Failure Rate Data: Stress - Strength | Constant Failure Rate | Manufacturer’s FMEDA | Databases
• On-line Diagnostics: Coverage Factor Definition | Diagnostic Methods | Coverage Effect on Safety and Reliability
• Fault Tree Analysis: Objective | Procedure | Symbols | Example
• Common Causes: Common Cause Defined | Reducing Common Cause | Stress - Strength View | Fault Tree Eexample | Beta Model
• Markov Models: Markov Model Defined | Simple and Complex Models | Building a Model | Solving a Model
• Reliability and Safety Modeling:  Procedure for SIF Modeling | Modeling Steps | Data Examples – Trip Amplifier, Analog Transmitter, Solenoid Valve | Example – Temperature Protection System
• Calculations: PFDavg.MTTFS | System Examples | Engineering Tools

Classroom/Laboratory Exercises:

• Calculating probability of failure
• Calculating PFDavg for 1oo1 SIF
• Calculating PFDavg for 1oo2 SIF

A calculator is helpful in this course.
