Elements and Performance Criteria
- Plan and prepare work
- Safety issues are identified to comply with enterprise/site requirements
- Work requirements are identified from relevant personnel and documentation
- Pre operational checks are carried out on plant according to manufacturer's recommendations and site requirements
- Where appropriate, the teams and individuals roles and responsibilities within the team are identified and, where required, assist in the provision of the on-the-job training
- Operate plant
- Pre-operational conditions are established in accordance with enterprise standards and site requirements
- Where the gas turbine is a component of a combined cycle unit pre-operational conditions of the Heat Recovery Steam Generator, associated steam mains and Steam Turbine are established in accordance with enterprise standards and site requirements.
- Starting procedures are commenced and correct purge, ignition and run-up sequence observed
- Minimum operation of gas turbine is established and supported in accordance with enterprise, manufacturer's and site requirements.
- Where the gas turbine is a component of a combined cycle unit monitoring and control of Heat Recovery Steam Generator drum level, feedwater flow, steam and metal temperature rates of rise, steam pressure rate of rise, steam flow and drainage are carried out in accordance with manufacturer's and site requirements
