Systems Theory Process Analysis Applied to Engineering Design Assessment

Process Safety Data is compiled, modified, reviewed, and amended during all steps in the lifecycle of a process plant. Maintaining this data can be quite challenging and costly. Updating data can result in a significant trickledown effect on subsequent steps in the plants lifecycle. By improving the Safety Lifecycle Data Flow, significant project time, and therefore cost, reductions can be achieved. This paper will review how information recorded in the various lifecycle phases needs to be transferred from one phase to the next, and how the overall data flow can be improved through integrated tool support. The paper will also discuss how this can lead to overall project cost and schedule reductions.
