Process industries
Continuous processes where a stop costs hours to recover from. Safety instrumented systems, advanced control and predictive maintenance do most of the work.
In a continuous process plant, a trip is not a pause; it is hours of recovery, off-spec product and sometimes a safety event. Our process industries practice is built around keeping the plant inside its envelope and catching problems before they become trips.
What process plants come to us for
- Safety instrumented systems designed, verified and maintained to IEC 61511 by certified engineers, with independent review. See quality and safety.
- Advanced process control that holds the process closer to its limits with less operator intervention.
- Predictive maintenance on refiners, pumps, fans, kilns and mills, the equipment that causes the longest recoveries. See the 40-site programme.
- Energy management in the most energy-intensive sector we serve, with reporting that stands up to audit.
