Gas Distribution Model (GDM)

> Objective ─ Industry standard data model for natural gas distribution

assets and operations

> Benefits─ Reduce cost and complexity of GIS and supporting

software integration─ Increase interoperability and reduce customization─ Facilitates electronic field data capture

GDM Drivers

> Why do we need a standard data model for the distribution industry?

─DIMP─ Shift towards electronic data and field data capture

─ Models and software require lots of data

─ Various different gas distribution data models

Applications for GDM

> Vendors─ Software standardization, ease of implementation, interoperability

> Data Compilation─ Combine data across different operations─ Vertical integration of data across sectors

>Industry Benchmarks and Data Collection Initiatives─ AGA, CGA, PPDC . . .

>Future Advancements─ Smart phones─ Smart tags─ ASTM traceability standard

Model Highlights

> Features ─ Designed for Distribution and Transmission systems─ Supports stationed and un-stationed pipe (stationing

is optional)─ Similar design concepts as PODS─ Oracle Spatial and SQL Server Spatial

> Uses geometry data types

Key Concepts

>Pressure System─ System of mains and related facilities fed by one or

more regulators─ Each pressure system has an MAOP based on the

MAOP of components within the pressure system─ Foreign key reference used instead of information on

individual pipe and component records

Key Concepts

>Linear Referencing and PODS Compatibility─ Distribution, transmission, and re-classifications─ Vertical integration─ Linear referencing but stationing is supported─ Supports Line, Route, and Series tables─ Adds EventRangeIndex table that eliminates the need

for Event and EventRange tables in PODS─ Maintained outside of the user environment and

managed by application software

Key Concepts

>Regulators and Regulator Stations─ Various levels of detail─ Single point with inlet/outlet pressure─ More detailed information regarding internal piping

>Service Points and Meters─ Link to meter is the CIS─ Foreign key used to link meter to DeliveryPoint

>History Tracking─ Non in-line history approach─ Optional companion tables

the Energy to Lead 14the Energy to Lead 14

> Table Categories─ Gas Pipe, Meta Data, Gas Systems, Tracer Wire─ Pipeline Centerline, Casings, Crossings─ Inspection and Maintenance─ Valves and Fittings, Metering, Receipt Points,

Regulators─ Conditioning equipment, Cathodic Protection─ Class, Markers and Signs, ─ Stations and Vaults─ Location and GPS─ Leak and Incident Reports

Status

>Logical and physical model complete

>Testing physical model in Oracle Spatial and SQL Server

─ Using basic test data set – primarily core tables─ Sample queries

>Developing an Implementation Guide

>Soliciting operator participants for pilot implementations

>Soliciting commercializers
