Turbine Control Systems

The control and protection of gas or steam turbines requires high integrity

as well as safety. The continuous operation of the fault-tolerant Tricon

controller provides the turbine operator with maximum availability while main

taining equivalent levels of safety.

Speed control as well as start-up and shutdown sequencing are implemented

in a single integrated system. Unscheduled outages are avoided by using hot

spares for the I/O modules. If a faultoccurs in a module, a replacement

module is automatically activated without operator intervention.

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.
