Boundary Management Part of the process included documenting a safe operating envelope that reflects process operability, safety and reliability constraints. The asset owner deployed the PAS PlantState Integrity - inBound from Hexagon application to identify and map the relationships of all operating envelope parameters, which are typically scattered and poorly documented. The application supports dynamic equations for each operating envelope boundary condition to determine when a constraint has been violated and provide notification to the process operators. More than 900 boundaries and 2,000 constraints were configured for the project. inBound also provides notification of configuration changes that violate the established boundary constraints. During platform testing and commissioning, dozens of changes to control system settings and logic were identified. In many cases, these planned changes did not reflect a full understanding of the complexity of the control schemes. For example, some proposed changes placed alarms on the wrong sensors or would have set trip points above environmental excursion settings. inBound identified and reported all such improper changes so that corrections could be made quickly. In the operational phase, inBound also shows the state of the platform in real time relative to all process boundaries and automatically tracks and reports exceedances, including their cost impact. The Result: Optimal Startup The optimization of the platform alarm system performance and boundary settings greatly improved both the efficiency of the startup and the safety of ongoing operations. The use of inBound ensured error-free configuration changes to alarm and trip settings in the post-startup optimization phase as well. Summary Alarm system design for a complex greenfield project poses unique challenges. Experienced people and the right tools can enable not only optimal and safe startup but also smooth operation in production.
