About the Course
Failure investigations are tough rigorous challenges form the best in engineering. This course will teach delegates the range of thinking and subjects, which need to be considered in driving to find the real root cause of a failure. The class will be based around some of the most difficult challenges faced by the professions in the industry and challenge the analytical and creative ability of the best students.
Jim Oswald has resolved many major gas turbine failures that can not be solved by many consultants before him. These cases will be presented on the course and there will be a lot of exercises to let the delegates have a deep understanding in solving major gas turbine failure.
Each attendee must bring a laptop computer with Microsoft operating system with Microsoft Excel and power point installed.
Course Objective: 
  • Identifying the true root cause of failures, consequences, sequences of failure and remedies
  • Understanding the interactions of components of gas turbine as a system including control systems and engine surge
  • Effectively organising and structuring an investigation plan
  • Experience first hand how fishbone analysis and Sequence of Events can help in investigations
  • Assessing fatigue failures and how it limits engine operational life
  • Assessing factors which limit reliable operation
  • Identifying the true root cause of failures, consequences, sequences of failure and remedies
  • Understanding, recognizing and preventing further repeat failures through pattern analysis
  • Strengthen understanding of gas turbine failures and operational limit concerns through thorough discussion with the trainer
Delegates will be reminded in how a gas turbine works, learn how to think through failure sequences and learn how to avoid misleading failure information
• How a Gas Turbines works, flows, controls, combustors, noise.
• Group Task with Case Study – Delegates will identify gas turbine failure and chart sequence of events before and after failure. Discussion on need for creativity in failure investigation based on Trainer’s experience.
• The importance of careful recording and how to record.
• Case Study
• Misinformation and how it occures
• Group Task – How to improve recording data



Delegates will learn about formal failure methods, how and why metal fails when and how best to use specialist
• Fishbone, RCA, Ishikawa
• Group Task – Redo chart of DAY 1 using formal method. Discuss and Compare the benefits
• Using Specialist expertise in GT Failure investigations: mellurgy, noise, vibration, controls
• When and how to use them in validation and discovery of evidence
• How to break metal: fatigue, creep, fracture, vibration
• The differences, and why its vital to understanding failures
• Case Study
• Group Task – identify if fatigue or creep from reports / photos provided. Judge if high cycle or low cycle fatigue
Day 3
Delegates will learn about a common cause of failure (fatigue) and work through case study work using methods taught and thus how to avoid a repeat failure
• Case Study
• Thermal Fatigue – What is it, how does it arrive and how leads to cracking and failure.
• Case Study
• Group task – calculate if thermal fatigue likely from data supplied
• Pattern of failures and why patterns matter
• Group task – identify patterns from data supplied. What does the pattern tell you?
• Group task – Delegates will be presented with failure evidence (based on real and serious failures) and asked to explain the failure using methods learnt. They will work in teams of 3 or 4. Trainer will act as engine operator and OEM. They need investigate and identify root cause followed by presenting the results to senior management.
