Carrying out tests on overhauled industrial power turbines

​

| --- |
|

This standard identifies the competences you need to carry out tests on overhauled industrial power turbines, as appropriate to the power turbine type, in accordance with approved procedures. You will be required to carry out all necessary preparations to the power turbine, in readiness for the tests to be carried out, and these will include ensuring that the power turbine is correctly mounted to the test facility, that all ancillary equipment is fitted to the power turbine, appropriate blanking plates are fitted, test instrumentation is correctly connected and that all necessary electrical checks are carried out.

In carrying out the tests, you will be required to follow laid-down procedures, to ensure that the working area is clear, appropriate guards and notices are displayed, power turbine runs/tests are carried out in accordance with the appropriate schedule, monitoring procedures are complied with, analysis of results is made, and that test documentation is completed, accurately and legibly.

Your responsibilities will require you to comply with organisational policy and procedures for the tests undertaken, and to report any problems with the testing activities that you cannot personally resolve, or that are outside your permitted authority, to the relevant people. You will be expected to work with a minimum of supervision, taking personal responsibility for your own actions and for the quality and accuracy of the work that you carry out.

Your underpinning knowledge will provide a good understanding of your work, and will provide an informed approach to undertaking the power turbine test procedures. You will understand the power turbine being tested, the specific test schedule to be followed, and will know what the various instruments and readings mean, in adequate depth to provide a sound basis for carrying out the tests to the required specification.

You will understand the safety precautions required when carrying out the testing activities, in particular those involved with fuelling and running the power turbines. You will be required to demonstrate safe working practices throughout, and will understand the responsibility you owe to yourself and others in the workplace.
