The document outlines the implementation of a Utility Pipeline Data Model (UPDM) for gas asset management by SCANA and PSNC, detailing the consolidation of GIS environments and the benefits of a centralized data model for improved analytics and regulatory reporting. It covers lessons learned in the project, including the integration of data across different platforms, addressing historical data management, and establishing user-friendly workflows for pipeline management. Key considerations include architectural setup, licensing for software extensions, and tips for data loading and management throughout the project.

10. Why UPDM?
SCANA’s Reasoning

11. Why UPDM?
- Eliminate duel editing and asset representation in two
database schemas
- Store and manage external data sets in central repository
- One system of record
- One location to store historical data
- Ability to view point in time asset information
- Ability to view prior years regulatory inputs and data
- PHMSA Reporting
- HCA, Class, Risk, MAOP inputs
- One managed network for analytics:
- Traceability
- Emergency Shutdown Analysis
- Outage Management

12. Why UPDM?
- GIS – Management: Single Database Infrastructure
- Backups, DB Tuning, DB Management
- Applications and Integrations
- Ability to program and configure against one location
- Streamlined integration points
- Clarity for the User Community
- Regulatory Reporting, Asset Views, Mileage, Summaries all
coming from one centralized location
- No need to compare and/or combine data from multiple locations
for reporting
- Future integrations with one GIS database for scheduling & WFM
- Ability to extend the viewing and consuming capabilities from one
centralized database
- ArcGIS Enterprise
- MAKE OUR GIS A DECISION MAKING TOOL!

13. ArcGIS Pipeline Referencing
Lesson #1 – Early Adopters

14. Early Adopters
• First companies on board, including SCANA, find UPDM
appealing since both the distribution and transmission gas
assets can be stored within the same enterprise
geodatabase
• Operators seeing the benefit of Esri out of the box tools
versus third party software products for core pipeline
management
• ArcGIS Pipeline Referencing – Centerline & Event
Management
• Pro – Distribution

15. Early Adopters
• Pure transmission operators (gas or liquids) have
historically stored in PODS (Relational/Spatial) or APDM
• With PODS Next Generation on the horizon and the
perceived jump from APDM to UPDM, we’ve found that
pure transmission operators are road-mapping and
planning prior to making the move
- Integration points to current PODS or APDM model
- Application compatibility (HCA/Class, Risk, MAOP/MOP
and Alignment Sheet Generation)
- Migration and Esri Version Upgrade Planning

16. ArcGIS Pipeline Referencing
Lesson #2 – Data

17. Data, Data, Data
• How are pipeline routes being stored in the new model?
- Past models, stored pipelines and systems in StationSeries
and LineLoop/LineLoopHierarchy tables.
- UPDM…review existing systems hierarchy and make key
decisions for modeling the pipeline LRS networks
• Do you still need historical stationing?
• Simply utilize continuous network and manage true pipeline
length/location?
• SCANA:
• PSNC Smallworld pipeline management versus SCEG Esri
(APDM) Data Management
• P_ContinuousNetwork

18. Data, Data, Data
• Data Mapping Phase
- Example: APDM.PipeSegment & APDM.Coating -> UPDM.P_Pipes
• UPDM Database Extensions
- Where is data duplicated?
- Where can we consolidate?
- Between both source datasets or within the same
- What fields are truly needed to support GIS asset and integrity
management
• Phased Data Migrations
- End User Review
- Application Testing

19. Data, Data, Data
• Data Migration
- Team Effort Between Esri Business Partners
• Established empty UPDM Schema
- Transmission
- Distribution
- Shared Features (P_Pipes, P_Fittings, P_Valves)
• Configure APR
- LRS Networks, LRS Events, etc
• Migrate Data from PSNC & SCEG

20. Data, Data, Data
• Current Project Utilizes FME (Smallworld) & Scripting
• Don’t discount the APR Toolbox!
- Streamlined Workflows
- GIS Centric
- Makes data loading a non-DBA task
- Append Events (Location Referencing Tools)
- Generate shapes and Event GUIDs
- Add, Retire or Replace

21. ArcGIS Pipeline Referencing
Lesson #3 – Architecture & Licensing

23. ArcGIS Pipeline Referencing Extension

- ArcMap/ArcCatalog Extension
- Create Empty UPDM Schema
- LRS Network Creation/Configuration
- LRS Event Creation/Configuration
- Event Responses
- Route Loading/Generation

24. Licensing and Deployment
• ArcGIS Pro Location Referencing Extension –
- Extension is part of the Pro Install!
- Named User versus Single Use?
- Single Use License: Provision APR as a single use on the same machine

25. Licensing and Deployment
• ArcGIS Pro Location Referencing Extension –
- Named User License: Use Pro License and the APR License
- Much easier to manage/implement
- Use Pro from any machine and utilize named user account for authentication
- Apply both to the named user via My Organization

26. Licensing and Deployment
• ArcGIS Desktop Location Referencing Extension
- Install the APR Extension
- Licensing Extension, user must enter text of Location Referencing Desktop
- Enable Extension within ArcMap/ArcCatalog

27. Licensing and Deployment
• ArcGIS Server Location Referencing Extension
- Must have ArcGIS Server 10.5 Installed
- When publishing Map Service, simply enable APR Web Editing

28. ArcGIS Pipeline Referencing
Lesson #4 – Tips!

29. Centerline and Data Loading
• For this project, we found it more streamlined to create the APR
core outside of the enterprise GDB and migrate once completed
- Centerline/Centerline Sequence/Calibration Point/Continuous
Network
- LRS Network/Event Configuration
• Migrate core features and LRS tables
- Follow Esri Documentation!
• The features/data that are migrated (outside the core) will assume
the LRS Network properties and users can proceed with using the
APR applications.

30. Centerline and Data Loading
• Append Events – Location Referencing Toolbox
- Your new best friend!
- Event GUIDs
- Create shapes from source data in a tabular format
- ROUTEID, M Value (From/To)
- Add, Retire or Replace
- Field Mapping – Visual Representation of Mapped Columns
