Operators: The Most Underutilized Resource in the Industry

Stephen Maddox

Control room operators have a very important job, in fact, they are the pilots of the process. Each 24hr operator position costs around $400K per year. They manage the automation system and have a direct effect on up time, down time, start up, process optimization, equipment, energy / waste consumption, product quality, and safety.

The “Alarms and Operator Intervention” safety layer is a critical defense when managing abnormal situations. During process upsets, operators have the chance to manage situations and prevent trips and safety system takeover. They have a massive impact on your bottom line. Many organizations overlook how beneficial they can be and often don’t understand or invest in human factors. This is a huge miss!

It’s time to change the culture! We need to get more from our operators! To do that, we must focus on human factors and implement best practices that will change the way we operate and utilize this valuable resource. The Operators are the most overlooked opportunity in the industry. It’s time we treat them as they are, the pilots of the process.

In some plants, operators are treated like annoying ugly step children, the sad fact is they are the eyes, ears, and masters of the process. There must be a good reason we have them. How much more value could they bring if we changed the way we valued them and focused on what they need? Some operators have increased productivity and efficiency, saved lives, improved product quality, reduced maintenance costs, and helped plant managers achieve production goals. Are your operators meeting and exceeding your expectations? Are your expectations set to low? Do you respect them and treat them as if they are the most important people in the plant? Isn’t the control room the operating system and most important room in the plant?

If you have high expectations and want to achieve a “High-Performance Operating Control Room” you should invest in your operators, before you can do that, you must change the culture. We have heard hundreds of stories “blaming the operators” or “all they do is sit there”. If you’ve spent time in a few control rooms, you probably know exactly what I’m talking about.

Operators significantly impact organizational goals. Hopefully management set goals that were clearly defined and communicated to everyone involved with operations. This way you can easily define the roles and expectations of each position, all of which should be aligned with the organizational goals. When you define the duties of the operators position you will quickly realize how important their job really is. Just check out this list of requirements for a good operator and you will see how important they really are. I remember hearing someone say, “operators should be picked up and dropped off every day in a limousine”.

Think about how important the automation system is. It requires human monitoring and intervention for it to work properly. Operators and the automation system go hand in hand, they are one system. Why would anyone spend millions of dollars on an automation system only to fall short on monitoring and intervention? Self-driving cars will be on the market one day, would you ride in the back seat or would you prefer to have the option to intervene if necessary? In my opinion, the operator is the most important component to an extremely complicated system. When the automation system fails, the operator actions usually have economic, environmental, and can have life or death consequences.

They also save and make the organization money when things are running good. Operators use trends to identify ways to reduce costs. They can identify equipment issues that can be repaired before the equipment needs to be replaced, this eliminates costly shut downs. Operators can identify abnormal situations and predict and prevent major incidents from occurring. Do you have a communication system in place to pick the operators brains periodically to identify automation or efficiency issues?

We need to think of them as the automation system managers. We need to look at the operators environment, user interfaces, and management systems to be sure they have everything they need in order to do what is expected of them. Find a human factors engineer (www.mycontrolroom.com) to do a study to identify gaps that effect operator performance.

So how do we change the culture? Develop higher standards for the operators. Look at your qualification requirements, interview process, training program and materials, and clearly define your expectations. We call this a “Gap Analysis” assessing operator effectiveness.

Treat operators as they are, the pilots of the process. Incorporate human factors engineering. Many companies use multiple vendors to implement their alarm systems, different ones to design and implement their HMI’s, and others to design and build their control rooms with no common philosophy or goals. So each does what they think is best and overall nothing works towards a common goal. What is that common goal? It is situation awareness, and more specifically the control room operator’s ability to detect, diagnose and respond to abnormal events. The goal, a High-Performance Control Room that integrates Alarm Management, HMI, and ergonomics into a single solution founded on an Operator Centered Design.

Words from a Process Supervisor: “If operators are trained properly from the beginning to understand the equipment they are responsible for, they will become great operators. Once they have been trained in the individual components, you circle back to tie the entire system together on how each machine, pipe, valve, or indication affects the system as a whole. Don’t do this and what you have is a monkey pushing buttons at the prescribed time. Do this and the attitude is then passed down to each operator that follows provided the same enthusiasm is met. With better automation, operators tend to be trained in start and stop but not the how’s and why’s. Then when a problem arises that they do not understand or have trained for, they are lost and receive a brow beating for not preventing the issue from management. Not only are control room operators valuable for the safe operation and monitoring of the plant, they should be the highest paid hourly personnel on the site”.
