Compressor failures can cause significant problems from delays in production to the possible shutdown of the whole plant. However, good compressor operation and maintenance can cost-effectively maximise compressor life expectancy; while improving its reliability and availability to meet output requirement.

 

Course approach:

This course aims to provide you with:

  • A very practical, interactive, experiential learning experience
  • A clear methodology applicable to all relevant organisations
  • Industry standard terminology and content
  • Rich content and solutions to site-specific issues
  • Interactive discussions

Key benefits and learning outcomes:

Over this 4-day training course, you will obtain valuable insights into:

  • Evaluating and augmenting the efficiency of compressor operation resulting in reduced energy consumption
  • Improving the knowledge of best practices and troubleshooting techniques to avoid and mitigate compressor failures
  • Defining the technical features and vulnerabilities of dynamic and positive displacement compressors
  • Identifying the criteria that can assist in cost-effective compressor selection
  • Using appropriate maintenance technologies to maximise compressor reliability and availability
  • Benchmarking compressor performance against industry standards

 

This course is aimed at:

Mechanical Engineers, Maintenance Engineers, Reliability Engineers, Electrical Engineers, Professional Engineers, Operations Managers, Maintenance Managers, Project Managers, Contract Managers, Asset Managers, Technical Managers.  From industries such as  Oil & Gas, Mining, Energy & Utilities, Chemicals & Petrochemicals, Food & Beverage Manufacturing, Agriculture
