Major-accident prevention
At a COMAH site, control and safety systems are key layers of protection. They must be designed, tested and maintained so that you and the Competent Authority can rely on them when it counts.
Industry brief
Oil & Gas
Safe, reliable control for terminals, pipelines and processing plant.
What matters
What matters most
Onshore terminals, pipelines and processing plants handle flammable hydrocarbons under pressure, close to people and the environment. Their control and safety systems must hold the process within safe limits, act correctly when it strays, and give you and the regulator clear proof that major-accident risks are under control.
Safety instrumented systems
Trips, shutdowns and permissives must achieve the SIL your hazard study requires, with proof testing and bypass management that stay practical for your operators and maintenance team.
Alarms operators can act on
In an upset, operators need to see the few alarms that matter. Rationalised, prioritised alarms and clear displays help them act quickly and correctly under pressure.
Cyber security
Control systems at terminals and pipelines are attractive targets. Segmented networks, controlled remote access and patching you can manage keep the process safe without slowing operations.
Solutions
Solutions for Oil and Gas
On a live hydrocarbon site, safety and production come first. We work within your permit-to-work and management-of-change procedures, prove new logic against a simulation of the process before it reaches site, and plan cut-overs around your shutdowns. You get the design, code and safety documentation to run and maintain the system yourselves.

The standards that shape your project
The standards listed are those most often relevant to control-system work in this sector. Which apply to your project, and how, is agreed with you at specification stage.
| Standard | What it covers | How we work with it |
|---|---|---|
| IEC 61511 | Safety instrumented systems for the process industry, across the whole safety lifecycle. | SIS logic designed and tested against your safety requirements specification and target SILs. |
| COMAH Regulations 2015 | Duties on operators of sites holding dangerous substances to prevent and limit major accidents. | Control and safety systems documented to support your major-accident prevention policy and safety report. |
| DSEAR 2002 and IEC 60079 series | Explosive atmosphere risk assessment and zoning, and the protection concepts for equipment in hazardous areas. | Instruments, panels and wiring specified to suit your hazardous area classification. |
| IEC 62443 | Cyber security for industrial automation and control systems, for owners, integrators and suppliers. | Its zones, conduits and security levels shape how we design networks and remote access. |
| EEMUA 191 and IEC 62682 | Good practice and requirements for designing and managing industrial alarm systems. | Alarm philosophy, rationalisation and prioritisation, so operators see what needs action. |
| Pressure Systems Safety Regulations 2000 | Safe design, protective devices, safe operating limits and examination of pressure systems. | Control and protective functions that keep plant within its safe operating limits. |
