Gas plant operators take care of the day-to-day operation of natural gas plants. They monitor all the units in the plant to ensure everything runs smoothly.

Gas plant operators’ duties vary depending on the size of the plant. Large facilities often require more operators and their jobs are specialized. Smaller gas plants may require fewer people who each have a wider range of duties.

Junior operators, sometimes called trainee operators, work in units in gas plants. For example, they may work in the sulphur handling unit where sulphur is removed. Or they may work in the treating unit where water and impurities are removed and the gas is separated into components. Under the direction of unit operators, junior operators:

  • Perform regular checks of their unit
  • Keep records of temperatures, pressures, concentrations and flows
  • Record various data in spread sheets and online tracking systems
  • Perform basic tests on the gas and chemicals at different processing stages
  • Test air samples for signs of gas or chemical leaks
  • Make adjustments to maintain the process or correct problems
  • Perform minor equipment maintenance and repair tasks
  • Assist in equipment maintenance such as changing oils and parts
  • Check chemical pump rates
  • Supervise loading and unloading of various methanols, glycols, solvents and oils
  • Ensure that flammable and other potentially dangerous products are in safe locations
  • Clean equipment and buildings
  • Assist in vessel clean-outs
  • Do site rounds to inspect tanks, fire extinguishers and fire suppression systems

Unit operators ensure that an entire unit operates smoothly. They train and supervise junior operators and assist with or conduct equipment inspections. They are also in charge of:

  • Starting up and shutting down plant equipment
  • Reviewing and compiling records taken by junior operators
  • Maintaining equipment and making minor repairs or requesting repair and maintenance work
  • Running product and boiler tests
  • Monitoring controls
  • Helping junior operators solve problems
  • Assuring the safety of others in their areas

Senior operators, sometimes called chief operators or lead hands, are in charge of operating several units. They usually are the most experienced operators on their shift. Senior operators spend most of their time working in a control room. They monitor numerous control panels, charts and an alarm system that sounds when a problem occurs. If adjustments need to be made in a unit, or an alarm goes off, senior operators call the unit operators concerned and outline the necessary procedures.

In sour gas plants, operators are trained in emergency evacuation and firefighting procedures.

Much of the work in gas plant operations is routine. Gas plant operators may go for long periods of time without a problem and then a serious failure or complication may occur. When this happens, operators must analyze the problem and act quickly and correctly.

Working Conditions
Updated Mar 31, 2020

Depending on the design of the plant, junior operators may spend about half of their time outdoors. Their job requires a lot of walking and lifting. Unit operators spend most of their time indoors but may be required to work outside when problems arise with outdoor equipment. Senior operators spend much of their time in the control room.

Gas plants operate 24 hours a day so operators work 8- or 12-hour shifts. They may need to work long hours to complete special tasks. Operators must follow safety precautions to avoid injuries resulting from exposure to toxic chemicals and gases.

  • Strength Required Lift up to 20 kg
Skills & Abilities
Updated Mar 31, 2020

Gas plant operators need:

  • Mechanical aptitude
  • Eye-hand coordination and manual dexterity
  • Good vision and hearing
  • Judgement and reliability
  • Agility and endurance
  • Attention to detail
  • An awareness of the need for cleanliness
  • A strong safety orientation
  • Math skills
  • Communication skills in English
  • An understanding of word processing, spreadsheets and similar applications

Gas plant operators should enjoy controlling equipment, instruments and machinery. They also should enjoy working in a team to analyze information and solve problems. They should be comfortable working under pressure and in high-stress situations.

Educational Requirements
Updated Mar 31, 2020

In gas plants that use generating sources other than steam, operators may not need specific formal education. However, a high school diploma with courses in mathematics, chemistry and physics is a definite asset. The following safety courses also may be required or recommended:

  • Confined Space Entry
  • Workplace Hazardous Materials Information System (WHMIS)
  • Hydrogen Sulfide Awareness (H2S)
  • Transportation of Dangerous Goods (TDG)
  • First Aid and CPR
  • Fall Arrest
  • Petroleum Safety Training (PST)
  • All Terrain Vehicle (ATV) Safety
  • Chainsaw Safety
  • Ice Rescue
  • Defensive Driving

Gas plants with power boilers or sulphur recovery units require that operators have an Alberta Power Engineering Certificate. For details about power engineering certification, see the Power Engineer occupational profile. Most employers also want operators to complete at least 1 or 2 Gas Processing Operations (GPO) courses.

Some companies provide in-house training opportunities to help gas plant operators advance to more senior positions.

Post-secondary schools that offer power engineering programs also may offer GPO courses and other gas plant operations training by distance education (computer-managed learning or modularized materials).

Employment & Advancement
Updated Mar 31, 2020

Gas plant operators work for oil and gas companies in gas plants. In general, these are located as close as possible to gas fields. Alberta has hundreds of gas plants, some near major cities and others in remote areas.

Individuals often start in field positions or as junior operators. Advancement to more senior positions such as unit operator and senior operator usually depends on experience and education. In gas plants that require power engineering certificates, operators may need higher certification to advance to senior positions.

Senior operators may move into supervisory positions. They may then advance to management positions located either at the plant or in major cities.

Gas plant operators are part of the larger 2011 National Occupational Classification 9232: Petroleum, gas and chemical process operators. In Alberta, 84% of people employed in this classification work in the following industries:

The employment outlook [pdf] in this occupation is influenced by a wide variety of factors including:

  • Trends and events affecting overall employment, especially in the industries listed above)
  • Location in Alberta
  • Employment turnover (when people leave existing positions)
  • Occupational growth (when new positions are created)
  • Size of the occupation

In Alberta, the 9232: Petroleum, gas and chemical process operators occupational group is expected to have a below-average annual growth of 1.3% from 2019 to 2023. In addition to job openings created by employment turnover, 78 new positions are forecasted to be created within this occupational group each year.
