About the Reliability Engineering Course

The reliability of a Plant or Facility determines its performance – process safety, environmental and cost performance all depend on it. It is thus a pivotal driver, which we can use to make significant business gains. Unfortunately it is often seen as a black art, best left to mathematicians or other specialists.

This practical training course will show you that it is easy to understand and explains how to use data from operating and maintenance records and get the results.

Course Instructors - Vee Narayan BMech, DipEE, DIM and Kenneth Lees BSc, MSc

Learning Outcomes

The links between maintenance and reliability, and the effect of Reliability on Process & Environmental Safety, Production volumes and maintenance costs will become clear in this highly interactive training seminar.

By attending this 5-Day training course, you will acquire the following:

- Learn reliability terms, their definitions and its use.
- Practice exercises to determine e.g., MTBF, MTTR, Scale and Shape factors etc. and learn how to use these to determine maintenance strategies and operating philosophies.
- Find out how Plant availability depends on reliability and see how configuration affects the outcome.
- Study different failure distributions and see why these matter. Exercises on spares holdings will show them how to optimize these to meet service level and cost considerations.

A number of tools including RCM, RBI, FMECA, IPF, RBD, FTA, ETA and RAM Modelling will be covered briefly, so that you know what to use where. Failure analysis using RCA will be discussed. The Business Process to manage Reliability Improvement and a roadmap to achieve high performance will be included.
