10) This relates to the competency standard unit as a whole providing the range of contexts and conditions to which the Performance Criteria apply. It allows for different work environments and situations that will affect performance. Systems, plant and/or equipment may include medium and high speed diesel engines; spark ignition gas engines and associated auxiliaries; electrical supply switchboard(s) and transformers; fans and pumps; valves, actuators and dampers (electric, hydraulic, pneumatic and manual); supervisory, alarm, protection and control equipment; starting systems; and fuel systems Safety standards may include relevant sections of Occupational Health and Safety legislation, enterprise safety rules, relevant state and federal legislation and national standards for plant Information and documentation sources may include verbal or written communications; enterprise safety rules documentation; dedicated computer equipment; enterprise/site standing and operating instructions; enterprise log books; manufacturer’s operation and maintenance manuals; and equipment and alarm manuals Technical and operational indicators may include stimuli (audio, smell, touch, visual), local indicators and recorders, computers and alarms (visible and or audible). Communications may be by means of telephone, two way radio, pager, public address system, computer (electronic mail) and operating log (written or verbal). Tests may include stand-by plant tests, post maintenance operating tests and black start Appropriate personnel to consult, give or receive direction may include supervisor/team leader or equivalent, technical and engineering officers or equivalent, power system control personnel or equivalent, contractor and specialist personnel, maintenance staff and power plant operations personnel. Test, fault finding and operating tools may include high voltage testers, proving dead equipment, power or hand tools and control system equipment. Operating environment may be during inclement or otherwise harsh weather conditions, in wet/noisy/dusty/hot areas or during night periods. Faults and abnormal operating conditions may include motor/pump/ actuator/valve/dampers failure/malfunctions, control equipment failure/ malfunctions, loss of electrical supply to plant and equipment, high engine/turbocharger/lubricating oil temperatures, low lubricating oil pressure/flow and excessive vibration pumps/motors. Medium speed diesels may have speeds below 500rpm but are engines of conventional design. The auxiliary equipment is generally remote from plant with separate energy supplies. These engines are medium to large in size and usually require platforms to conduct service and inspection. The monitoring points are at individual sections or components. High speed diesel engines may have speeds as low as 1000rpm. These engines are of conventional design and are small and compact. The auxiliary equipment is generally integrated with, and powered by, the engine. The monitoring points are usually collective and not at individual sections or components. Generic terms are used throughout this Training Package for vocational standard shall be regarded as part of the Range Statement in which competency is demonstrated. The definition of these and other terms are given in Section 2.1 Preliminary Information and Glossaries. |
