Gas HCA Analyst
Leveraging the power of ArcGIS and ArcObjects technology, this extension identifies DOT 192.5 Class Locations and 192.905 High Consequence Areas (HCA).
Gas HCA Analyst offers operators two methods to accurately identify High Consequence Areas: by including all Class 3 and 4 Location areas or by counting structures and Identified Sites within a Potential Impact Circle. This application calculates the HCA and the Potential Impact Circle based on the C-FER radius and generates graphics to visually identify these locations for field verification and potential integrity alignment sheet generation.
The application is easy and flexible to configure when calculating parameters for “what if?” scenarios and allows for greater consistency when executing Integrity Management Plans.
Features
- Identify Part 192.5 Class Locations
- Identify Part 192.905 High Consequence Areas (HCA)
- Select method for HCA determination using either existing Class 3 and 4 locations or structure count within the Potential Impact Circle
