The integrated control safety system (ICSS) at the Lacq Gas Processing Plant required an extensive renovation as it was based on Contrôle Bailey Alspa-ZS systems dating back to the mid eighties.
The old control systems of the Lacq natural gas plant dated from the mid eighties and were showing signs of ageing: increasing failure rates (the sour atmosphere is a rather aggressive environment), scarcity of spare parts, and decreasing availability of competent maintenance personnel capable of supporting / maintaining these old systems.
A new gas processing unit was to be put in service in 2005, requiring a new process control system and safety controllers. It was then decided to use this opportunity to launch a major renewal of the complete ICSS covering the entire plant.
