Gas HCA Analyst

Calculate DOT Class Locations, identify High Consequence Areas (HCAs), and determine regulated onshore gathering lines for gas pipeline networks.

Gas HCA Analyst is a flexible ArcGIS extension that helps pipeline operators address three major DOT regulations:

• 49 CFR 192.5 Class Location determination
• 49 CFR 192.903 High Consequence Area identification
• 49 CFR 192.8 Regulated Gathering Line determination

Gas HCA Analyst pulls pipeline data from its existing Oracle, SQL Server, or Access database; there is no need to create a secondary database of pipeline attributes. The user is provided with a variety of configuration options to ensure that their unique system design and integrity management framework is addressed. Those configuration settings are stored for future use to drive consistent results and to enable time-based comparisons along the pipeline network.

The application follows a “show your work” philosophy when producing results. Every Class Location and HCA determination is accompanied by the project settings and accompanying metadata for project validation. Those results can be distributed as Crystal Reports, tabular files, or feature classes in ArcMap.

Features

• Identify Class Locations, High Consequence Areas, and regulated onshore gathering lines
• Apply method A or B to determine HCAs
• Access pipeline data direct from an Oracle, SQL Server, or Access database, regardless of data model
• Analyze both attribute and geometric networks
• Store configuration settings such as database connections, buffers, and structure classification
• Associate structures with the pipeline using the snap method or the Arc method
• Set default values for pipe data where it is unavailable or to perform “what-if?” scenarios
• Apply clustering methods to produce precise Class Location results
• Perform Class Location analysis continuously across pipelines
• Apply a buffer to the analysis for areas where centerline accuracy may be in question
• Identify the reasoning for HCA determination as identified site or SIHO
• Integrates with ArcMap to visually identify HCA locations for field verification and alignment sheet generation
• Export results and logic to Geodatabase, Crystal Reports, or tabular format
• Apply pre-configured Crystal Reports templates
• Compare results between analyses as a feature in ArcMap or in tabular format
