Application Scenarios:

In a coastal LNG terminal, the regasification process demands uninterrupted control of cryogenic pumps and safety shutdown systems. A single controller failure could lead to production halt or safety incidents. The ABB PM867K02​ was deployed in a redundant pair. The primary controller managed the complex PID loops for pressure control, while the secondary unit ran in hot-standby. When a simulated primary CPU fault occurred, the system switched over in under 10 ms, with no disruption to the process valves or operator view. This addressed the terminal’s core need for zero-downtime​ in a hazardous environment, ensuring both production continuity and functional safety compliance
