Introduction

Compressors are common in almost all industrial systems and applications. Compressors represent a significant part of capital and operating costs on most plants.

Gas turbine is a major power source used in the generation of electricity, and the driver of choice for modern aircraft, pumps, compressors etc. This training course covers main topics of operation and maintenance of gas compressor and turbines and associated support systems. In addition, the course develops a background in gas turbine operation that enables participants to analyse operating problems properly and take the necessary corrective action. The course combines between the basic and practical considerations related to centrifugal compressors. The use of gas turbines in the petrochemical, power generation and offshore industries has increased considerably during the past few years.

The course will cover the design, installation, operation and maintenance of these machines by highlighting characteristics features, efficiencies, reliability and maintenance implications. Upon completion of this course, participants will gain a complete and up-to-date overview of the Gas Turbine technology.

A Vibration- Monitoring system gives warnings when vibration levels reach a pre-set level, and hence provides a round- the - clock watch on vital machinery. The training course aims to provide a treatment of the detection and diagnosis of faults in rotating equipment using vibration measurement and analysis.

Objective

Upon successful completion of this course, the delegates will be able to:

  • Learn the principles of the centrifugal compressors and gas turbine.
  • Familiarize with various types of centrifugal compressor & gas turbine.
  • Explain operation principles of the centrifugal compressor and gas turbine.
  • Discuss about maintenance procedure of the centrifugal compressor and gas turbine.
  • Discuss the troubleshooting and failure analysis of the centrifugal compressor and gas turbine.
Audience

Turbine & compressor maintenance engineers of relatively short experience and senior technicians of medium experience who have the ability to improve & develop their capabilities. Members of the following departments: Engineering, Planning, Procurement, Operation, Maintenance or Inspection and those who are engaged in or intend to be familiar with compressor systems. Also senior staff should update and refresh their knowledge by attending this course.
