Maintenance Engineers maintain a range of machinery and instruments used in the electricity supply industry (ESI) for generating electric power.
Personal requirements of a Maintenance Engineer may include:
- Ability to follow procedures and commitment to safe work practices
- Good at mechanical and/or electrical activities
- Able to accept responsibility and make decisions
- Logical and thorough approach to work
Mechanical Engineers of power generation plants may complete the following tasks:
- Tests and calibrates, to established standards, equipment such as pressure and temperature transmitters, valve positioners, pneumatic controller, electronic controllers, pressure and temperature switches and other process control equipment.
- Installs, adjusts, inspects, services and repairs a variety of mechanical equipment and mechanical parts of electrical machinery utilized in an electrical power station including vertical and horizontal hydro-electric and thermal generation equipment. Overhauls and adjusts turbines, generators, boilers, pumps, valves, pneumatic controls and auxiliary equipment.
- Makes repairs on high pressure vessels, such as boiler tubes, hand holes, drums, steam lines, fire boxes, nose castings and expansion joints; welds turbines, diaphragms, condensers, compressors, centrifugal pumps, pump shafts and generators; uses stainless steel, cast iron, brass, aluminum, copper and other alloys.
- Manufactures replacement parts and repairs and refinishes metal components using special machine shop equipment such as carbide tool grinders, hydraulic shears, hand saws, hydraulic presses, milling machines and lathes.
- Installs insulation, metal covering, and insulating blankets on high-pressure stem piping, low-pressure steam piping, air, and condensate, low and high-pressure water lines. Removes and reinstalls insulation when lines need maintenance.
- Develops, implements and maintains an effective program of equipment and outage maintenance work; performs equipment inspections to ensure that the equipment is safely maintained and operable; performs related testing and repair as needed.
- Installs, tests and maintains heating, ventilating and air conditioning such as compressors, condensers, pumps, control systems, fans humidifiers, chillers and heat exchangers.
- Installs, tests, maintain and repairs high voltage generators, motors, actuators equipment, turbine controls, station auxiliaries, lights and control measuring devices.
- Supervises a program of preventive maintenance of the electrical and/or mechanical equipment, structures and building of power station operation; makes regular inspections and tests of facilities to determine the overall condition of the power plant.
- Performs basic routine task of the assigned craft; completes required course work as an apprentice.
- Provides direct oversight and on-the-job training to apprentices.
- Coordinates with other crafts on logistics of assigned projects.
- Evaluates performance or provides input in evaluating employees.
- Plans and assigns jobs to crews; may serve as a field engineer to solve problems on site.
- Insures availability of parts and supplies, by assessing jobs and determining parts that are needed for the job.
Some positions will require two years of experience in digital or analog electronics, or process control instruments; or completion of a course of study in electrical or electronics at a recognised trade, technical or vocational school.
The Power Plant Maintenance Technician job family consists of four levels of work, which are distinguished, by the level of complexity, of the assigned duties and responsibility assigned and the level of expertise for the completion of assigned projects.
Knowledge, Skills and Abilities for this role at the basic level include ability to read, interpret and carry out complex written or oral instructions; and possess general knowledge of the methods, practices, tools, materials and machines used in the assigned craft.
Education and Experience requirements at the basic level consist of two years of experience performing skilled maintenance work in one of the following maintenance crafts: electrical, mechanical, machinist, H.V.A.C., insulator or electronic/instrumentation; or two years of experience staging parts, equipment and materials in a large industrial warehouse or for large construction jobs; or completion of two years of a four year apprenticeship program in the maintenance craft to which assigned; or completion of a two year course of study, in the maintenance craft to which assigned, at a recognized trade, technical or vocational school; or an equivalent combination of education in maintenance and experience in maintenance.
