Commissioning engineers are engaged in the testing of facilities, equipment and plants to make sure they function correctly and produce the expected results. In doing so they bring the product or system to a point at which it can be used most effectively. Commissioning engineers therefore need to possess a thorough understanding of manufacturing and product use, as well as of customer expectation.

Commissioning engineering embraces the installation and commissioning of all types of engineering projects, so commissioning engineers can be found in all branches of engineering.

Work activities

  • Identifying problems and shortcomings with existing systems.
  • Co-ordinating testing and commissioning activities and providing advice on testing and commissioning procedures and documentation.
  • Producing or assisting in the production of all test and commissioning documentation.
  • Undertaking testing and commissioning activities in line with the specified site requirements.
  • Monitoring progress, recording all test results, witnessing final testing and acceptance of equipment and compilation of all documentation for inclusion in the site test dossier.
  • Ensuring the safe testing and commissioning of completed installations to achieve the necessary plant performance in accordance with project programme requirements.

Working hours: regular office hours with occasional long days and some weekends depending on projects deadlines. Overnight and weekend stays away from home may be required.
Location: throughout the country though much will depend on the branch of engineering.
