February 6, 2012, Houston, TX – PAS, a leading supplier of human reliability software and services to the power and processing industries worldwide, today announced the release of inBound, an application that makes plant operators continually aware of safe operating limits.
Safe operating limit information is maintained by various groups within the plant and is not readily available to operators. Thus operators are generally unaware of the design and safety limitations of the processes they operate.
inBound is a layered application for PAS’ market-leading PlantState Suite© alarm management software. It aggregates, validates, and displays physical constraints such as a vessel’s Maximum Allowable Working Pressure (MAWP), design constraints such as relief valve settings, and safe operating limits. These constraints may be manually entered, calculated, or imported into inBound from engineering applications and databases.
inBound enables engineers to develop a boundary hierarchy and automatically detects and reports deviations from that hierarchy, such as an alarm setting that is higher than a pressure-relief valve setting. This capability provides assurance that configuration parameter changes such as alarm limits and instrument ranges remain within the safe operating envelope of the plant.
inBound displays safe operating limits in real time and in context within the plant’s existing control system graphics, enabling operators to proactively monitor and take action as needed to prevent violation of limits. “A compelling use for inBound is the monitoring of environmental limits.” said Eddie Habibi, Founder and CEO of PAS. “Exposing these limits in context enables operators to visualize the process’s proximity to boundaries in real time, and take action before an excursion occurs”.
