Smarter Pipeline Intelligence Through GIS Automation

Regulatory analyses often require evaluating thousands of pipeline segments, structures, environmental features, waterways and operating conditions. Traditional approaches can be time-consuming, difficult to validate and challenging to maintain across changing assets.

IntegrityMap HCA automates these complex analyses through a transparent and repeatable workflow that provides:

• Consistent and defensible classifications
• Reduced manual review and processing time
• Audit-ready documentation and reporting
• GIS-based visualization and analytics
• Traceable methodologies and assumptions
• Scalable analysis across large pipeline systems

The result is greater confidence in regulatory compliance, integrity management planning and operational decision-making.

IntegrityMap HCA for Gas Pipelines

For gas pipeline operators, IntegrityMap HCA provides automated analysis of class locations, high consequence areas (HCAs), moderate consequence areas (MCAs) and gathering systems in accordance with applicable regulatory requirements.

Class Location Analysis

IntegrityMap HCA automates structure identification, counting and pipeline segmentation to support Class 1 through Class 4 determinations aligned with 49 CFR §192.5. The platform helps operators maintain up-to-date classifications while reducing the effort associated with manual evaluations.

High Consequence Area (HCA) Identification

IntegrityMap HCA combines potential impact radius (PIR) calculations, structure and population information, identified sites and pipeline geometry to support repeatable HCA determinations and segmentation.

• Automated potential impact radius (PIR) calculations
• Method 1 analysis
• Method 2 analysis
• Structure and population evaluation within potential impact areas
• Identified site screening and evaluation
• Automated HCA segmentation and GIS output
• Traceable source data supporting HCA determinations

These capabilities provide a consistent framework for identifying HCA segments and supporting integrity management programs.

Moderate Consequence Area (MCA) Analysis

IntegrityMap HCA extends the spatial analysis beyond HCA determinations to support MCA screening and pipeline segmentation using the applicable population, structure, roadway and regulatory criteria.

• Moderate consequence area screening
• Population and structure-based evaluation
• Applicable roadway and regulatory criteria
• Automated MCA segmentation and GIS outputs
• Traceable results supporting integrity-management review

The result is a more complete view of regulated consequence areas and the pipeline segments associated with them.

Gathering System Classification & Reporting

IntegrityMap HCA supports gathering pipeline evaluations by applying location, pipeline characteristics and applicable regulatory criteria to identify and document gathering classifications.

• Automated gathering pipeline classification
• Type A, Type B, Type C and Type R evaluations
• Diameter, material, pressure and location-based criteria
• Class location integration
• Population and structure proximity analysis
• Regulated gathering segment identification
• GIS segmentation, data outputs and reporting
• Audit-ready documentation

This helps operators maintain consistent, defensible records for regulatory review and internal governance.

IntegrityMap HCA for Liquid Pipelines

For hazardous liquid pipeline operators, IntegrityMap HCA applies physics-based spill consequence modeling to evaluate how a release could move through the environment and impact sensitive resources. Unlike traditional fixed-distance approaches, the workflow considers operating conditions, terrain, hydrology, shutdown response, drain-down volumes and isolation scenarios to produce realistic and defensible consequence assessments.

Worst Case Discharge & Release Modeling

IntegrityMap HCA evaluates:

• Scenario-specific release volumes
• Operating condition modeling
• Shutdown and response effectiveness
• Pipeline drain-down calculations
• Valve-to-valve segment analysis
• Elevation-based volume assessments
• Available spill volume determination

These analyses help operators understand potential release scenarios and associated consequences.

Spill Routing & Consequence Analysis

The platform models how released product may travel across terrain and through waterways using:

• Terrain-controlled overland flow analysis
• Pooling and low-slope identification
• Thin-film Manning flow calculations
• Waterbody and waterway entry detection
• Hydrologic connectivity analysis
• Downstream channel routing
• Travel time and velocity assessments
• DEM-based routing methodologies

This creates a comprehensive picture of potential spill pathways and impacts.

HCA Impact Analysis

IntegrityMap HCA identifies and evaluates potential impacts to sensitive resources through:

• Modeled impact footprints
• HCA intersection analysis
• Source-to-impact traceability
• Consequence-based segmentation
• Spill spacing evaluations
• Could-affect determinations
• Consequence-based asset classifications

This provides operators with defensible impact assessments that support integrity programs and regulatory requirements.

EFRD Scenario Analysis

IntegrityMap HCA supports emergency flow restricting device (EFRD) studies by comparing existing isolation performance against alternative EFRD scenarios and quantifying how changes in isolation strategy may affect spill consequence.

• Baseline isolation performance
• Alternative EFRD scenarios
• Release volume reduction potential
• Travel distance comparisons
• HCA exposure reduction opportunities
• Consequence ranking of alternatives

These analyses help operators evaluate how isolation strategies may influence spill consequence and risk.

From Regulatory Questions to Defensible Answers

IntegrityMap HCA is designed to connect regulatory and integrity management questions to traceable spatial answers. For gas systems, the platform helps identify where classifications and consequence areas occur, why they occur and which pipeline segments are affected. For liquid systems, it connects release volume, modeled spill movement and HCA impacts back to the pipeline locations capable of affecting those resources.

This source-to-result traceability gives operators a repeatable basis for review, documentation and decision-making without turning complex regulatory analyses into disconnected manual workflows.

Deliverables Designed for Compliance and Decision-Making

IntegrityMap HCA produces a wide range of deliverables to support regulatory review, engineering studies and integrity management programs, including:

• GIS feature layers and spatial datasets
• Pipeline segmentation outputs
• HCA and MCA analyses
• Structure count databases
• Impact footprints and consequence maps
• Dashboard reporting
• Scenario comparison analyses
• Attribute tables and data summaries
• Audit-ready documentation

All outputs are generated through a repeatable workflow that promotes consistency and transparency across projects and asset systems.
