Unit of Competency UEGNSG139 - Repair and maintain stationary gas fuelled turbine engines
Description
Employability Skills
Learning Outcomes and Application This unit involves the skills and knowledge required to isolate, disconnect, repair, reconnect and maintain stationary gas fuelled turbine engines up to a capacity of 5 gigajoule per hour (GJ/hr) (1,300 kilowatt).It includes disconnecting, carrying out repairs and replacing fuel train components to stationary gas fuelled turbine engine. Reconnecting the gas fuelled turbine engine includes pre-start tests, start up, adjusting components and controls to safe and efficient operation, and completing all required documentation.This unit does not cover:repairs to the internal mechanical components of the enginemodifications to gas fuelled turbine engine.Note: 500 kw equates to a gas input of approximately 6 GJ/hr.The application of the skills and knowledge described in this unit may require a license or permit to practice in the workplace.Other conditions may apply under state and territory legislative and regulatory licencing requirements which must be confirmed prior to commencing this unit.No licensing, legislative or certification requirements apply to this unit at the time of publication.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Range is restricted to essential operating conditions and any other variables essential to the work environment.

Non-essential conditions may be found in the UEG Gas Industry Companion Volume Implementation Guide.
