Abstract

Leveraging DIMP Results for Engineering Analysis
Track: Pipeline and Gas Utilities
Authors: Clark Tenney, Julie Williams

In order to satisfy DIMP requirements, Questar Gas Company chose to implement ESRI's DIMP Model Builder template to analyze risk on its gas distribution system. Based on end user feedback, it was concluded that enhancements to the base ESRI model, additional post processing models and customized tools in ArcGIS Server would be necessary to meet DIMP analysis requirements. Post-processing models were created to leverage intermediate data for display and analysis purposes in ArcGIS Server. Additional post-processing models were created to enable reporting in ArcGIS Server. Implementing custom reporting and query tools in ArcGIS Server enabled users to effectively view, analyze and report on the final DIMP results. This presentation will discuss how the enhancements to ESRI's DIMP model, the post-processing models, and the customized ArcGIS Server map display met the end user requirements helping them to satisfy DIMP requirements and formulate accelerated actions or other strategies in high risk areas.
