01 · Control Room Design

Control rooms and control centres built on ISO 11064

“If you think Human Factors is expensive, try an accident.”

Whether you are building a new control room (CR), centralising several control rooms into one central control room (CCR) or upgrading an existing one, safe, efficient and reliable operation is now the top priority for operators and authorities alike. Operators play a critical role in monitoring, supervising and running complex automated systems, and as automation has grown, so have the consequences of equipment and human failures.

A wrong action in a CR or CCR can be devastating, which is why Human Factors is a vital part of designing and evaluating control rooms. We help you avoid designing “beautiful” errors. An attractive control room is not always a functional one. Functionality comes from human-centred design that involves the end users: operators, shift supervisors, maintenance staff, DCS suppliers and third-party consultants.

Which standard should you use?

Many control room standards are used across industries, including ISO 11064, NORSOK S-002, EEMUA 201, NUREG, CRIOP, ANSI/HFES 100 and HSG48. There are also company standards and guidelines, plus national regulations to consider.

ISO 11064 is the most complete and widely accepted of them. Its seven parts cover the central control room, control suite, control room, workstation design, displays, work environment, and validation and verification. Its aim is good working conditions for human safety, health and wellbeing, while keeping technology and costs efficient.

Watch: we explain ISO 11064 and how it is used in control room design.
Part 1Principles for the design of control centres

Nine principles: human-centred design, ergonomics in engineering practice, improvement through iteration, situational analysis, task analysis, error-tolerant systems, user participation, an interdisciplinary design team, and documenting the ergonomic design basis.

Its framework for an ergonomic design process is probably the most important part: clarification (data gathering), analysis and definition, conceptual design (such as 2D or 3D design), detailed design, and operational feedback, with end users involved at every stage.

Part 2Principles for the arrangement of control suites
Defines the starting point for laying out a control suite: system functions, allocation of functions to operators or equipment, job definitions (job rotation, training level), work tasks and their relationships, frequency and workload, and a preliminary description of the equipment.
Part 3Control room layout
Ergonomic principles for control room layouts, workstation arrangements, off-workstation displays and maintenance. It covers all types of control centre, from the process industry to transport and emergency dispatch. Many of its principles also apply to mobile centres on ships and aircraft.
Part 4Layout and dimensions of workstations
Principles, recommendations and requirements for control workstations, with emphasis on layout and dimensions. It applies mainly to seated, display-based workstations, but standing workstations are covered too.
Part 5Displays and controls
Principles, requirements and recommendations for displays and controls, and how they work together, in control centre hardware and software.
Part 6Environmental requirements for control rooms
Requirements for the thermal environment, air quality, lighting, acoustics, vibration, aesthetics and interior design, whether you are designing, upgrading or refurbishing.
Part 7Principles for the evaluation of control centres
Requirements and guidelines for evaluating each element of a control centre: control suite, control room, workstations, displays and controls, and work environment.
02 · Human Machine Interaction

HMIs that help operators make the right decisions

“A poor HMI is often a source of incidents in the industrial world.”

Humans and machines interact through displays and controls. HMI is usually short for Human Machine Interface. We use the broader term Human Machine Interaction, whether screens or physical controls are involved.

An HMI is the set of screens, graphics and other technology operators use to monitor and work with control systems such as DCS or SCADA. Poor HMIs were named as a significant contributing factor in the 2005 Texas City refinery explosion. A good HMI makes the use of displays and controls safe, reliable, efficient and comfortable, especially in abnormal situations.

How we can help

Whether you need a complete HMI philosophy with standards and toolkits, or small changes to existing interfaces, we simplify the communication between operator and equipment and improve efficiency and job satisfaction along the way.

03 · Alarm Management

Alarms worth the operator's attention

“Alarm floods are a well-known, significant contributing cause of industrial incidents.”

Alarm management matters wherever human response to an alarm is relied on to control major accident hazards, from small storage sites to plants with a central control room and a full DCS. The principle is the same everywhere: make sure people respond correctly to alarms, through good interface and system design, monitoring and review, competence and procedures.

Alarm systems are used in chemical manufacturing, power generation, oil and gas, rail and transport, nuclear and more. The US Chemical Safety Board names alarm floods as a significant contributing cause of industrial incidents (Beebe et al., 2012).

Standards and the alarm lifecycle

Two standards dominate alarm management: ANSI/ISA-18.2 (Management of Alarm Systems for the Process Industries) and EEMUA 191 (Alarm Systems: a Guide to Design, Management and Procurement).

The ISA-18.2 lifecycle usually starts with an alarm philosophy. It continues with identification, rationalisation, detailed design, implementation, operation, maintenance, monitoring and assessment, management of change, and audit.

04 · Function & Tasks

Allocating work between people and automation

Function and task analysis should be carried out and documented to identify ergonomic needs, such as involvement, analysis and the solutions needed to reach the goals.

It supports an integrated design for your central control room by helping you:

  • Define system performance
  • Allocate functions to humans or machines (automation)
  • Define task requirements
  • Design the job organisation
  • Verify and validate the results

05 · Workload & Workflow

Work systems that fit human capabilities

“Defining workload and workflow often reduces human error.”

The goal is a work system that matches human capabilities, limitations and needs. When designing jobs and work organisation, identify the lines of communication (internal and external), interactions between people, work permits, and who does what in an abnormal situation.

Shift handover and night shifts matter too. Our circadian rhythm means that at night it takes longer to refocus during an abnormal situation. Moving some tasks from the night shift to the day shift can help prevent incidents.

How we can help

We map the workload and workflow of each operator, involving all end users.

  • Task allocation: dividing work tasks between operators and systems
  • Task zones: combining each task with its space and location requirements
  • Work space: the space one or more people need to complete a task

06 · CR / CCR Risk Assessment

Identify risk, evaluate risk, make an action plan

Operators at their consoles in a control room with large process overview screens

Control room operations have changed. Industrial companies are centralising several control rooms into one central control room, automation has matured and costs must come down. More automation often means fewer staff, and operators have moved from running the plant to observing and analysing it. That calls for a new approach to risk management.

In a central control room, operators lose much of their ability to see, hear, feel (such as temperature or vibration) and smell what is happening in the plant. Instead they rely on technology and on other people to interpret the situation. Tacit knowledge, which is hard to transfer from senior to junior operators, must not be lost along the way. Noise from communication and alarms, and how abnormal situations are handled, also need careful assessment.

How we can help

Centralisation often moves functions from operators to the DCS and may create or remove tasks. We identify and evaluate these risks and create an action plan, often using a scenario-based method. Risk assessment is preventive work that reduces human error in your future control room.
