AbstractThe operator of a complex process facility is aided in executing step by step procedures by a computer based system which incorporates monitored plant data and interactive plant operator responses to prompts to progress step by step through selected procedures. At each procedure step the plant status is evaluated and a recommended course of action is identified. The results are displayed on a visual display device to provide operator guidance for executing the procedure in effect. Parallel process monitoring visually alerts the user to conditions not considered by the current step of the active procedure, and where the seriousness of the other condition warrants, provides procedure-based recommendations for priority action. The system can be accessed by multiple users at separate locations for coordinated execution of a single procedure or simultaneous execution of two different procedures. A permanent chronological record of the step by step execution of the selected procedures including the pertinent plant conditions and operator responses, and the parallel monitored status tree conditions is also generated by the system for subsequent review and analysis.
