Operating environment may be remote from the plant and equipment being operated, (in cases where operation is assisted by remote indication of operating parameters and plant status), during inclement or otherwise harsh weather conditions, in hot/wet/noisy/dusty/elevated/confined or enclosed areas or during night periods. Plant operations (systems requirements) may include: Returns to service with the heat recovery steam generator in a cold, warm or hot condition; heat recovery steam generator internal chemical clean; raising pressure to allow steam main blow-out; raising pressure to allow safety valve setting, operational testing. Operational tests may include: Loss of a major auxiliary control response checks; drum level protection tests; stand-by plant "cut-in" tests; dampers/valves operating checks and pre and post start tests Faults and abnormal operating conditions may include: Excessively high or low steam/water drum level, loss of a major auxiliary; loss of electrical supply to switchboards, drive motors or valve actuators; feedwater chemical operating limits exceeded; automatic control loop(s) malfunctions; high temperatures on/in, heat recovery steam generator heating surfaces/tubes/headers, low temperatures on/in, heat recovery steam generator heating surfaces/tubes/headers; High/low superheater or reheater steam temperatures; high temperatures on/in: motor and/or pump bearings, lubricating oil or motor windings; heat exchange element tube leaks; excessive drum water level split; excessively high heating/cooling rates; high differential pressures on oil/air filters and strainers; failed field devices; failed/malfunctioning actuators/dampers/valves; feedwater pumps malfunctions 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.
