What is Fault-Tolerant Control?

A fault-tolerant control system identifies and compensates for failed control

system elements and allows repair while continuing an assigned task

without process interruption. A high integrity control system such as the

Tricon is used in critical process applications that require a significant degree

of safety and availability.

Offshore Fire and Gas Protection

The protection of offshore platforms from fire and gas threats requires

continuous availability as well as reliability. The Tricon provides this avail

ability through online replacement of faulty modules. Faults in individual

modules, field wiring and sensors are managed automatically by built-in

diagnostics. Analog fire and gas detectors are connected directly to the

Tricon, eliminating the need for tripamps. An operator interface monitors

fire and gas systems as well as diagnostics for the Tricon controller and its

attached sensors. Traditional fire and gas panels can be replaced with a single

integrated system, saving costly floor space while maintaining high levels of

safety and availability.
