Centrifugal Compressor & Steam Turbine


This seminar entails a study of gas compression and expansion laws applied to industrial processes followed by an illustration of the different types of rotating machines usually encountered in plants, and their related aspects. The aim is to provide a satisfactory approach to the problems posed by compressors and turbines and the means to solve them.

Key highlights of the course are:

  • Understanding of monitoring techniques as applied to compressors and turbines
  • Ability to put in place measures to quantify equipment condition
  • Interface with and control service providers
  • Identify and specify new compressor and turbine plant


At the end of this seminar, participants will have:

  • An understanding of the construction and operational constraints of centrifugal compressors and steam turbines
  • Knowledge of how to optimally maintain the equipment for the benefit of the company
  • Hints and Tips for practical application of monitoring technologies so as to achieve the best results

Training Methodology

The seminar will be conducted along workshop principles with formal lectures, case studies and interactive worked examples. Relevant case studies will be provided to illustrate the application of each tool in an operations environment. Each learning point will be re-enforced with practical exercises. There will be ample opportunities for discussion and sharing experiences.

Organisational Impact

Predictive maintenance of rotating plant is vital to the budgetary success of the operations organisation. On completion of this seminar, the delegate will be able to critically analyse the methodologies employed within the organisation and instigate improvements where required.

Personal Impact

Technical knowledge is key to effective control and peer respect within any maintenance organisation; when this is achieved personal satisfaction follows. This seminar will give the delegate the required level of technical knowledge and skill to achieve that personal satisfaction.

Who Should Attend?

  • Engineers, Operators, and Technicians in Maintenance, Engineering and Production
  • Anyone who wishes to update themselves on Maintenance Engineering Technologies, judges the suitability of these technologies for their needs, and learns how to implement them for the benefit of their organisations
