Gas Facility Initiatives Based on Single Data Repository

Non Core Application User Access

• Citrix Server Clients using the Company internal Intranet

– ArcMap, and Code Compliance Applications run on Citrix Server and results are displayed on their desktop

– No Software distribution to users machines– Home access using VPN technology– Far less Network Traffic

• ArcIms Clients using Company internal Intranet

– Hybrid approach using ArcIms and PDF files

System Planning and Emergency Dispatch

• All 455,000 gas main segments are used in GIS system planning model

• 1.6 Million Customer taps on gas main– Used in determining location of loads– Used in determining bypass size in outages– Used to build lists of customers without gas for light

ups in an emergency outage

System Planning

Stoner SynerGEE - Gas Load Analysis (Pressure Gradients)

Cathodic Protection (CorCon)

• All pipe, test leads, test stations, anodes, and rectifiers reside in the GIS database.– Information is available to Leak survey for code

compliance of unprotected pipe. – Test leads now reside in test stations which may

contain leads from multiple sectors– The application easily identifies using ArcMap

interface the pipe segments in a cathodic sector

CorCon Stand Alone

ArcMap and CorCon Application

Leak Survey (LeakCon)

• Leakcon application manages modules containing pipe and services to survey.– Business rules are maintained in the application to

determine when mains and services need to be surveyed

– Each pipe segment knows when it was surveyed last and when it should be surveyed next

– Each service knows when it was surveyed last and when it needs to be surveyed next

• Using the ArcMap interface the application easily identifies the pipe segments in a Module

ArcMap and LeakCon Application

Regulation Equipment Inspections (RegCon)

• All regulation facilities and equipment reside in GIS – Provides data about the inside of a regulator facility so

overpressure protection analysis can be done.– Each piece of equipment knows when it was inspected last

and when the next inspection needs to be done.• Using the ArcMap interface the application easily

identifies Regulator locations and the equipment inside the facility

ArcMap and Regcon Application

Decision Analysis Spreadsheets

• Civic Improvement Model– Water main,sewer replacements and paving

projects– Input from techs in each of the 9 areas into a very

detailed spreadsheet– ArcMap is now used to populate facility data

• Material Condition Model– Deteriorated pipe in each of 9 areas rated for

replacement – Leak survey results, leaks, leak repairs and

cathodic protection reads pulled from GIS
