|
5 | Respond to gas turbine problems | 5.1 | Monitor turbine and its component plant items frequently and critically throughout shift using measured/indicated data and senses |
| 5.2 | Describe impacts of any changes upstream and downstream |
| 5.3 | Recognise actual and developing situations which may require action |
| 5.4 | Apply operational knowledge to resolve problems |
| 5.5 | Take other appropriate actions on abnormal situations which cannot be resolved during the shift to ensure safety and the resolution of the situation |
| 5.6 | Follow through items initiated until final resolution has occurred |
|
6 | Isolate and de-isolate turbine and its component plant items | 6.1 | Shut down turbine according to the turbine type and duty in liaison with other personnel |
| 6.2 | Shut down/changeover component plant items within unit according to their type and duty in liaison with other personnel |
| 6.3 | Isolate entire turbine system and/or any component plant item |
| 6.4 | Make safe for required work |
| 6.5 | Check turbine/plant item is ready to be returned to service |
| 6.6 | De-isolate and prepare turbine/plant unit/plant item for return to service |
Evidence required to demonstrate competence in this unit must be relevant to and satisfy the requirements of the elements and performance criteria, and include the ability to:
use data and own senses to monitor plant and maximise performance
perform pre-start checks, start-up/shutdown procedures, and isolations and de-isolations
identify early warning signs of equipment/processes needing attention or with potential problems and take the action specified in procedures
identify hazards and risks and apply risk control procedures.
Evidence must be provided that demonstrates knowledge of:
all items on a schematic of the turbine and functions of each
turbine operating principles, including fuel injection, lubrication, cooling, ignition, induction and exhaust power supply
interactions between plant items/processes
systems’ operating parameters, integrity limits, product specifications and tolerances, temperature, pressure and flow
process-specific science (physics and chemistry) to the level of being able to interpret the science and extract factors controlling the process and product
correct methods of starting, stopping, operating and controlling
isolation procedures
emergency shutdown procedures
function and troubleshooting of major components, their problems and the resolution of those problems
basic science of upstream and downstream processes
hierarchy of control
hazards that may arise in the job/work environment, and:
their possible causes
potential consequences
appropriate risk controls.
The unit should be assessed holistically and the judgement of competence based on a holistic assessment of the evidence.
The collection of performance evidence:
should occur over a range of situations which include typical disruptions to normal, smooth operations
will typically include a supervisor/third-party report focusing on consistent performance and problem recognition and solving. A supervisor/third-party report must be prepared by someone who has a direct, relevant, current relationship with the person being assessed and who is in a position to form a judgement on workplace performance relevant to the unit of competency
must include the use of industrial type gas turbine allowing operation
may use industry-based simulation for part of the unit particularly where safety, lack of opportunity or significant cost is an issue.
Assessment should occur in operational workplace situations. Where this is not possible, or where personal safety or environmental damage are limiting factors, assessment must occur in a sufficiently rigorous simulated environment reflecting realistic operational workplace conditions. This must cover all aspects of workplace performance, including environment, task skills, task management skills, contingency management skills and job role environment skills.
Assessment in a simulated environment should use evidence collected from one or more of:
walk-throughs
pilot plant operation
demonstration of skills
industry-based case studies/scenarios
‘what ifs’.
Knowledge evidence may be collected concurrently with performance evidence (provided a record is kept) or through an independent process, such as workbooks, written assessments or interviews (provided a record is kept).
Assessment processes and techniques must be appropriate to the language, literacy and numeracy requirements of the work being performed and the needs of the candidate.
Conditions for assessment must include access to all tools, equipment, materials and documentation required, including relevant workplace procedures, product and manufacturing specifications associated with this unit.
The regulatory framework will be reflected in workplace policies and procedures and is not required to be independently assessed.
Foundation skills are integral to competent performance of the unit and should not be assessed separately.
Assessors must satisfy the assessor competency requirements that are in place at the time of the assessment as set by the VET regulator.
In addition, the assessor or anyone acting in subject matter expert role in assessment must demonstrate both technical competency and currency. If the assessor cannot demonstrate technical competency and currency they must assess with a subject matter expert who does meet these requirements.
Technical competence can be demonstrated through one or more of:
relevant VET or other qualification/Statement of Attainment
appropriate workplace experience undertaking the type of work being assessed under routine and non-routine conditions
appropriate workplace experience supervising/evaluating the type of work being assessed under routine and non-routine conditions
Currency can be demonstrated through one or more of:
being currently employed undertaking the type of work being assessed
being employed by the organisation undertaking the type of work being assessed and having maintained currency in accordance with that organisation’s policies and procedures
having consulted/had contact with an organisation undertaking the type of work being assessed within the last twelve months, the consultation/contact being related to assessment
conducting on-the-job training/assessments of the type of work being assessed
being an active member of a relevant professional body and participating in activities relevant to the assessment of this type of work.
