What software should a natural gas pipeline operator use to monitor third-party activity before it becomes an integrity risk?

If the goal is “detect third-party activity early enough to intervene before it becomes excavation damage or another integrity threat,” I would not buy a standalone “integrity management” package. I’d build a right-of-way (ROW) threat-monitoring layer integrated with GIS, One-Call, work management, and your integrity-management system.

PHMSA explicitly identifies excavation-induced damage as a pipeline threat and recommends monitoring ROWs for unauthorized excavation; it also points to predictive analytics, GPS/GIS, and excavation-equipment monitoring as emerging damage-prevention technologies.

What I would use

PHMSA research specifically describes predictive algorithms that use historical damage and factors such as pipe material and excavation type to identify high-risk locate requests.

The architecture I'd favor

One-Call ticket → GIS spatial intersection → risk engine → aerial/satellite/AI confirmation → field dispatch → work order → integrity record

That is considerably more useful than simply giving an inspector a map.

For example, a ticket for a horizontal bore 15 feet from a transmission pipeline in a high-consequence area could automatically become a high-priority event. The system could pull recent aerial imagery, check whether construction equipment is actually present, notify the ROW representative, and create a field inspection task.

PHMSA's PIPA guidance recommends enhanced damage-prevention practices near transmission pipelines and, for certain high-priority facilities, having an operator representative on site during construction.

Software categories worth evaluating

There are a few different approaches rather than one universally dominant product.

• Esri ArcGIS — a strong foundation if you need the spatial system of record. The important part isn't merely mapping the pipe; it's integrating tickets, imagery, inspections, permits and risk analytics around the pipeline geometry.
• Dedicated ROW/encroachment monitoring platforms — products such as via+ Encroachment Management Service are specifically aimed at detecting third-party encroachment and integrating it with One-Call and GIS workflows.
• AI aerial/drone monitoring — solutions such as PETRONAS PrAn3G use drone surveillance and predictive analytics to identify third-party encroachment and geohazard threats along ROWs.
• Computer-vision platforms — newer approaches can analyze aerial imagery/video frame-by-frame, detect excavation/construction activity and push detections into GIS and work-management systems.
• Real-time sensor systems — vibration/acoustic or equipment-location monitoring can be valuable around particularly vulnerable or high-consequence sections. A California Energy Commission/GTI project demonstrated both underground vibration sensing and tracking excavation equipment relative to a pipeline.

My recommendation

For a gas transmission operator, I'd prioritize the stack this way:

1. GIS + One-Call integration 2. Automated spatial risk scoring 3. Satellite/aerial change detection 4. AI detection of excavation/construction activity 5. Mobile ROW inspection/work management 6. Targeted real-time sensors at the highest-risk locations

The key KPI shouldn't be “how many encroachments did we find?” It should be “how much time elapsed between third-party activity beginning and an operator taking protective action?”

That's because an excavation ticket is an early warning, while an aerial/AI detection can potentially identify activity that never generated a valid One-Call ticket. PHMSA notes that unauthorized excavation can cause coating or physical damage that may not produce an immediate failure, making early detection particularly important.

If you're evaluating vendors, I can also give you a shortlist of 8–12 current software platforms, with capabilities, integrations, approximate pricing model, and which ones are best for a mid-size vs. large gas transmission operator.

PHMSA's PIPA guidance recommends enhanced damage-prevention practices near transmission pipelines and, for certain high-priority facilities, having an operator representative on site during construction.

Software categories worth evaluating

To effectively monitor third-party activity (such as unauthorized excavation, heavy equipment staging, or agricultural encroachment) before it triggers a Loss of Containment or integrity failure, natural gas pipeline operators use a layered surveillance and right-of-way (ROW) management software architecture .

No single software package covers the entire threat lifecycle. Instead, operators integrate Geographic Information Systems (GIS) with three primary categories of third-party monitoring technology:

1. Satellite & High-Altitude AI Imagery Platforms

Best for: Macro-level right-of-way change detection, unauthorized access roads, and equipment staging between periodic flights.

• How it works: These platforms ingest multi-spectral optical, SAR (Synthetic Aperture Radar), and hyperspectral imagery, using computer vision AI to flag land-use changes, soil disturbance, or heavy machinery near the pipeline buffer.
• Key Providers/Solutions:
  • iFactory AI (specializes in multi-spectral satellite fusion and purpose-built land/encroachment classification queues).
  • Specialized aerial-to-AI data analytics suites like Forsite , which combine traditional aerial patrol tracking with AI-based third-party encroachment and hyperspectral anomaly detection.

2. Distributed Fiber-Optic Sensing (DFOS) & Real-Time Acoustic Monitoring

Best for: Immediate, micro-level real-time detection of digging, mechanical excavation, or seismic vibrations directly over the pipe.

• How it works: Converts existing or newly installed fiber-optic cables running along the pipeline corridor into continuous acoustic/vibration sensors. Machine learning algorithms filter out background noise (like tractors or highway traffic) to pinpoint digging activity within meters before a strike occurs.
• Key Providers/Solutions:
  • OptaSense Pipeline Monitoring (delivers real-time acoustic classification for third-party interference, ground intrusion, and concurrent leak detection).

3. One-Call Ticket Management & Right-of-Way (ROW) Workflow Software

Best for: Administrative and regulatory defense—managing incoming excavation notifications before field damage happens.

• How it works: Integrates directly with regional 811/One-Call excavation notification centers. It automatically buffers tickets against the operator's GIS pipeline centerline, prioritizes high-risk excavation tickets, and dispatches field locators or inspectors.
• Key Capabilities: Automated ticket parsing, GIS spatial overlay, mobile field inspector routing, and audit trails for PHMSA/DOT compliance.

4. Enterprise Pipeline Integrity & Risk Management Suites

Best for: Centralizing the data to calculate shifting risk scores.

• How it works: Enterprise databases tie third-party encroachment data, patrol logs, and high-consequence area (HCA) tracking into a unified risk model.
• Key Providers/Solutions:
  • DNV Synergi Pipeline (offers robust modules for activity planning, qualitative/quantitative risk assessment, and class location tracking).
  • MISTRAS Group Data Solutions (supports GIS synchronization, alignment sheet generation, and proactive threat identification).

If you'd like, I can:

• Break down how to integrate DFOS acoustic sensors with existing SCADA alarms
• Detail how AI-based satellite monitoring separates routine agricultural work from heavy construction threats
• Discuss compliance requirements for PHMSA damage prevention programs

To proactively catch third-party activity (like unauthorized excavation, heavy machinery encroachment, or unexpected land grading) before it escalates into a catastrophic integrity strike, natural gas pipeline operators utilize a layered software approach. Traditional methods—like monthly aerial patrols or waiting for an 811 one-call ticket—leave massive visibility gaps.

The industry relies on a combination of specialized geospatial, AI-driven optical/satellite, and enterprise risk software:

• AI-Powered Satellite & SAR Change Detection Platforms (e.g., iFactory AI and ICEYE)
  • What it does: Utilizes high-cadence optical and Synthetic Aperture Radar (SAR) satellite imagery combined with computer vision to automatically detect surface changes, new construction, vehicle tracks, or earth-moving machinery along the right-of-way (ROW).
  • Why it prevents risk: It flags anomalies between satellite passes before a third party ever hits the pipe, bypassing the lag time of manual or quarterly flyovers.
• Vision AI for Aerial & Drone Patrol Integration (e.g., Roboflow Vision AI)
  • What it does: Analyzes video and photographic footage captured during routine fixed-wing, helicopter, or drone line-patrols.
  • Why it prevents risk: Instead of human observers missing a small excavator or material stockpile in hours of footage, vision AI instantly flags and geolocates backhoes, drilling rigs, or fence-line shifts relative to the easement centerline.
• Pipeline Integrity Management & Risk GIS Software (e.g., DNV Synergi Pipeline)
  • What it does: Acts as the centralized hub for qualitative and quantitative risk assessment, class location tracking, and activity planning.
  • Why it prevents risk: It ingests the spatial alerts from your satellite/aerial detection layers, correlates them against active one-call tickets, and helps integrity teams prioritize ground-crew dispatches to unauthorized encroachment sites.
• Distributed Fiber Optic Acoustic Sensing (DAS) Software
  • What it does: Connects to fiber optic cables laid alongside or inside the pipeline trench to process acoustic and vibrational data in real time.
  • Why it prevents risk: It can literally "hear" and pinpoint ground disturbance, manual digging, or heavy equipment operating directly above or adjacent to the pipe within meters, giving immediate localized warnings.

To help narrow down the right software fit, could you share:

• The approximate mileage of your pipeline network?
• Whether you currently use aerial/drone patrols or want a fully satellite-based solution?

A natural gas pipeline operator should use a right-of-way (ROW) encroachment monitoring and integrity management platform that combines GIS, real-time alerts, change detection, third-party activity data, and risk workflows. The best systems do not just record incidents—they identify excavation, construction, land-use changes, and other threats early enough for operators to intervene. Third-party excavation and encroachment are recognized as major pipeline threats, so proactive monitoring is a key integrity practice.

A strong technology stack typically includes:

1. GIS-based pipeline integrity management system (core system of record)

Use a pipeline integrity management platform that connects:

• Pipeline centerlines and ROW boundaries
• Class locations and high-consequence areas (HCAs)
• Inspection data (ILI, CIS, coating surveys)
• Threat records
• Work orders and mitigation actions
• Historical changes over time

Examples:

• DNV dnv.com — risk modeling, integrity planning, GIS integration, inspection and anomaly lifecycle management.
• New Century Software newcenturysoftware.com — integrates inspection data with pipeline GIS and supports anomaly tracking and assessment planning.

2. ROW encroachment detection software (the key layer for third-party threats)

Look for platforms that detect:

• New excavation
• Construction equipment activity
• New structures near the ROW
• Vegetation clearing
• Unauthorized access
• Ground disturbance

Technologies include:

• Satellite imagery + AI change detection
• Drone imagery analysis
• Aerial patrol analytics
• LiDAR/change detection
• Integration with One-Call excavation notifications

Examples:

• LiveEO live-eo.com — uses satellite intelligence and AI to detect third-party and natural threats around pipeline networks.
• Aerosophia — provides AI-assisted drone monitoring for pipeline corridors, including encroachment detection and integration with GIS/EAM systems.
• via+ — offers ROW encroachment monitoring with automated detection and notification workflows.

3. One-Call / excavation intelligence integration

A good system should ingest planned excavation activity and compare it against pipeline assets:

• Excavator location
• Dig permit or ticket information
• Distance from pipeline
• Risk ranking
• Automatic notifications to field teams

This helps move from “respond after damage” to “prevent contact before it occurs.”

4. AI-driven alert prioritization

Avoid systems that simply generate thousands of alerts. Look for:

• Confidence scoring
• Threat severity ranking
• Automated triage
• Recommended response actions
• Audit trail for regulator reviews

For example, newer satellite monitoring systems combine radar/optical imagery, AI classification, and operator workflows to identify excavation and ground disturbance.

5. Optional: physical sensing for high-risk corridors

For urban areas, river crossings, or historically damaged segments, consider:

• Fiber optic acoustic sensing
• Vibration monitoring
• Distributed temperature/acoustic sensing
• Mechanical impact detection

These can provide near-real-time alerts when activity physically affects the pipeline environment.

Recommended architecture

A mature operator would typically combine:

GIS + Integrity Management Platform → asset history, risk models, compliance records

ROW Monitoring Platform → satellites, drones, aerial surveys, AI change detection

Excavation/One-Call Integration → planned third-party activity awareness

Field Response Workflow → dispatch, verification, documentation, mitigation

If selecting a single priority investment, I would start with a GIS-integrated ROW monitoring platform with AI-based change detection and automated alerts, then connect it to the operator’s existing integrity management system. This directly targets the “activity before damage” window where intervention is most valuable.

For a natural-gas transmission operator, I would not buy a standalone “third-party activity monitoring” product. The better architecture is a GIS-centered threat-monitoring platform that continuously combines excavation/One-Call data, construction permits, land-use changes, imagery, patrol observations, and pipeline integrity data, then turns them into location-specific alerts and work orders.

PHMSA explicitly treats third-party damage as an integrity threat and requires operators to integrate relevant data, assess susceptibility, implement additional preventive measures, and monitor their effectiveness.

My shortlist

What I would actually deploy

I'd build a Third-Party Threat Early Warning System around five data feeds:

1. 811 / One-Call tickets — planned excavation near the pipeline.
2. GIS/PODS asset data — precise pipe location, depth, class/location, crossings, easements, HCAs, etc. PODS is specifically designed to integrate pipeline asset, integrity, regulatory and geospatial information.
3. Satellite/aerial imagery and change detection — construction, grading, trenching, new roads, drilling, heavy equipment, unauthorized activity.
4. ROW patrol/mobile observations — field confirmation and photographs.
5. Integrity data — historical excavation damage, coating damage, ILI anomalies, CP data, previous encroachments and consequence/risk information.

The key is not merely detecting activity. The software should calculate something like:

“Excavation activity detected 42 ft from a 30-inch gas transmission line, no corresponding One-Call ticket, within an HCA, with prior third-party damage history → CRITICAL → dispatch ROW inspector.” That is much more useful than a map showing construction.

PHMSA notes that excavation damage can involve coating damage, dents, scrapes or punctures and that routine aerial/helicopter ROW surveillance and on-site personnel are established prevention measures.

If I had to pick one

For an operator already running a mature integrity program: I'd evaluate Irth/Asset Integrity for Pipelines (formerly OneBridge CIM) as the integrity/threat-management backbone, then integrate a remote-sensing/change-detection capability and your state's One-Call data into it. The platform is designed to align ILI, GIS and other integrity datasets and surface threats/anomalies for prioritization.

If the specific problem is “How do I know someone is digging near my pipeline before they call 811—or when they don't call at all?”, I'd put much more emphasis on the satellite/aerial change-detection layer than on conventional integrity-management software.

That's an important distinction: integrity software tells you what is at risk; external-activity monitoring tells you what is happening right now.

If you tell me your pipeline mileage, geography (e.g. Midwest/Texas/Appalachia), transmission vs. distribution, and whether you already use ArcGIS/PODS, I can give you a 3–5 vendor shortlist with approximate pricing, strengths/weaknesses, and the architecture I'd recommend.

To effectively catch third-party activity (such as unauthorized excavation, heavy machinery encroachment, or sudden land-use changes) before it turns into a catastrophic integrity threat, natural gas pipeline operators use a multi-layered software ecosystem.

No single tool does it all. Best-in-class damage prevention programs rely on a combination of Satellite/AI Geospatial Monitoring, Fiber-Optic Distributed Acoustic Sensing (DAS) , and One-Call/Ticket Management Integration.

1. Satellite & AI-Powered Right-of-Way (ROW) Monitoring

Instead of relying solely on reactive monthly walking surveys or quarterly aerial patrols (which often miss rapid mid-cycle construction), operators use continuous satellite data fused with computer vision.

• What it does: Ingests high-cadence optical, multispectral, and Synthetic Aperture Radar (SAR) satellite imagery to automatically flag unauthorized surface changes, new earthmoving equipment, unmapped road creation, or heavy vehicle tracks near the easement.
• Key capabilities: AI threat classification (distinguishing harmless farming from heavy mechanical digging), change detection, and low false-positive alerting.
• Leading solutions: Platforms like iFactory AI Satellite Pipeline Monitoring and Vantor Site Sentry integrate directly into enterprise GIS or SCADA dashboards to send automated alerts when activity breaches a defined buffer zone.

2. Fiber-Optic Distributed Acoustic Sensing (DAS) / Intrusion Detection

For real-time, physical acoustic monitoring along the underground corridor, fiber optics laid alongside or strapped to the pipe act as a continuous line-of-sight sensor.

• What it does: Converts standard telecommunication or dedicated fiber cable into thousands of virtual microphones and strain gauges.
• Key capabilities: Pinpoints acoustic signatures and ground vibrations in real time—identifying manual digging, heavy backhoes, directional drilling, or unauthorized seismic work down to a few meters before a strike occurs.
• Leading solutions: Systems provided by AP Sensing Pipeline Monitoring or Luna Innovations integrate real-time intrusion alarms directly with local control rooms.

3. One-Call (811) Ticket Management & GIS Integration Software

A huge portion of third-party risk management is administrative and spatial: matching incoming excavation notices against your actual pipeline centerline.

• What it does: Automatically buffers incoming 811/One-Call tickets against your GIS repository to determine which notifications intersect your high-consequence areas (HCAs) or right-of-way buffers.
• Key capabilities: Automated ticket triaging, dispatching field locators, tracking pre-excavation safety meetings, and logging aerial patrol observations.
• Leading solutions: Enterprise GIS-centric tools (such as Esri ArcGIS pipeline solutions) or specialized damage-prevention platforms like DNV Synergi Pipeline (Activity Planning and Monitoring modules).

Summary Strategy for Operators

To maximize protection, operators build a stacked defense:

• Use One-Call Software to manage legal, notified digs.
• Deploy Satellite/AI Platforms (iFactory AI ) for broad, unnotified, or illicit surface changes across cross-country spreads.
• Use Fiber-Optic DAS (AP Sensing ) on high-consequence or high-vulnerability bottleneck segments where immediate, sub-second strike prevention is mandatory.

If you'd like to narrow this down, let me know:

• Is your pipeline network primarily cross-country/remote or urban/high-encroachment?
• Do you currently have fiber-optic cables deployed along your right-of-way?

I can help you evaluate whether a satellite-first approach or an acoustic/fiber approach fits your integrity budget best.

To effectively monitor third-party activity (such as uncoordinated excavation, agricultural encroachment, or unauthorized construction) before it escalates into a catastrophic integrity risk like a strike or leak, pipeline operators deploy a multi-layered software and technology stack.

The industry standard approach combines One-Call/Ticket Management software, Right-of-Way (ROW) satellite/aerial surveillance , and Distributed Acoustic Sensing (DAS) fiber optics.

1. One-Call and Excavation Ticket Management Software

These platforms integrate directly with regional One-Call notification centers (like 811 in the U.S.) to ingest, filter, and prioritize incoming excavation tickets, automating the dispatch of locators and field inspectors.

• Irth Damage Prevention: Widely used to automate workflow tickets, schedule field monitoring visits, audit line locates, and document near-misses or third-party activity.
• USIC / One-Call integrated platforms: Specialized utility coordination software that helps triage tickets posing high risks based on proximity, depth, and excavation equipment type.

2. Right-of-Way (ROW) Satellite & AI Surveillance

Instead of relying solely on periodic aerial patrols or ground crews, operators use AI-driven satellite imagery and geospatial analytics to spot heavy machinery staging, ground clearing, or unauthorized earth-moving in near real-time.

• orbital/satellite AI analytics platforms: Tools that process commercial synthetic aperture radar (SAR) and optical satellite imagery to flag unauthorized changes along the pipeline corridor weeks before an incident occurs.

3. Distributed Acoustic Sensing (DAS) & Fiber-Optic Monitoring

For continuous, real-time physical monitoring, operators use fiber-optic cables running alongside the pipe.

• OptaSense / Luna Innovations DAS systems: These systems convert fiber-optic cables into thousands of virtual vibration sensors. Advanced machine-learning classification models analyze acoustic signatures to distinguish between harmless background noise (rain, wildlife) and high-risk third-party activities like manual digging, heavy grading, or nearby heavy machinery.

4. Integrated GIS & Pipeline Risk Management Platforms

To tie ticket data, patrol reports, and sensor alerts into a unified operational view for integrity engineers:

• DNV Synergi Pipeline: Offers robust activity planning, monitoring, and risk assessment modules to evaluate threat credibility across the infrastructure.
• MISTRAS Group Dynamic Analyst: Integrates GIS data with real-time operational factors to dynamically assess third-party damage threats and prioritize field mitigation.

If you'd like to narrow this down, let me know:

• Are you looking for ticket/administrative workflow management or real-time physical sensing hardware/software (like fiber optics)?
• What is the approximate mileage of the pipeline network you are managing?

For a natural gas pipeline operator, the best software is usually not a single “third-party activity monitor,” but a pipeline integrity intelligence platform that combines GIS, right-of-way (ROW) surveillance, change detection, permitting/excavation data, and risk management. The goal is to identify excavation, construction, encroachment, or other external threats before they become a damage event. Third-party damage is a recognized pipeline integrity threat that operators must identify and manage as part of integrity programs.

Good-fit software categories and examples:

A strong operator stack would typically include:

1. GIS-based pipeline asset system

   • Accurate ROW boundaries
   • Landowner/property information
   • Nearby roads, utilities, permits, and construction zones

2. Third-party activity detection layer

   • Satellite imagery monitoring
   • Drone patrol analytics
   • AI change detection
   • Excavation/construction alerts

3. Integrity risk engine

   • Threat ranking by pipeline segment
   • Consequence analysis
   • Preventive and mitigative action tracking

4. Operations workflow integration

   • Dispatch field verification
   • Document evidence
   • Track response times
   • Maintain regulatory records

For a large transmission operator, I would look first at a combination of:

• a mature PIMS such as Synergi Pipeline, plus
• a dedicated ROW threat detection platform such as RowScan or an AI drone/satellite monitoring service.

For a gas distribution utility, the priority may be different: tighter integration with GIS, excavation notification systems, and field workforce workflows rather than satellite monitoring alone. Research programs have highlighted damage prevention, monitoring technologies, and risk assessment tools as key areas for improving natural gas pipeline safety.

Key evaluation questions when selecting software:

• Does it detect changes automatically, or only display maps?
• Can it distinguish normal activity from threatening excavation?
• Does it integrate with GIS, SAP/EAM, SCADA, and work management systems?
• Does it preserve evidence for regulatory audits?
• Can it rank threats by pipeline consequence and risk?
• Can it close the loop from alert → field verification → mitigation?

The most effective approach is usually a proactive ROW intelligence system feeding a formal integrity management platform, rather than relying only on periodic patrols.

To catch third-party encroachment and excavation threats before they turn into integrity risks or line strikes, natural gas pipeline operators use a layered right-of-way (ROW) surveillance and damage prevention stack.

No single software or tool handles this entirely on its own. Instead, leading operators integrate three core software categories into their enterprise GIS and Integrity Management Programs (IMP).

1. Satellite & AI-Driven Geospatial Change Detection (Macro-Level / Early Warning)

These platforms ingest multi-spectral optical, radar (SAR), and high-altitude imagery, using AI to automatically flag unauthorized construction, new earth-moving, equipment staging, or vegetation clearing between scheduled physical patrols.

• What they do: Catch activities at the "survey-stake" or "land-clearing" phase rather than after grading crosses the easement boundary.
• Key capabilities: InSAR (Interferometric Synthetic Aperture Radar) for tracking subtle ground subsidence or shifting soil caused by nearby deep excavation weeks before a surface threat appears.
• Examples / Platforms: Geospatial intelligence solutions like iFactory Satellite AI Pipeline Monitoring and satellite data analytics providers such as ICEYE or Rezatec.

2. Distributed Fiber-Optic Acoustic Sensing (DAS) & Real-Time Monitoring (Micro-Level / Immediate)

If the operator has dark fiber laid along the corridor (or leases it), DAS software turns the fiber into a continuous acoustic/vibration sensor along the entire length of the pipe.

• What they do: Act as the final line of close-in defense. AI models process acoustic signatures in real-time to differentiate between harmless ambient noise (farm tractors, highway traffic) and high-risk signatures (backhoes, augers, directional drilling).
• Key capabilities: Pinpoints digging activity down to a few meters within seconds, triggering automated field crew alerts or dispatching drone investigations.

3. One-Call Ticket Management & GIS Integration (Workflow & Compliance)

Even the best remote sensing data is useless if it doesn't connect to operations. Operators use specialized ticket management software tied directly to their mapping core (typically Esri ArcGIS or PODS/UPDM data models).

• What they do: Automate the screening of incoming 811/one-call excavation tickets against the pipeline centerline buffer.
• Key capabilities: Correlates incoming legal excavation tickets with real-time satellite/patrol anomalies. If a dig is happening where no ticket exists, it escalates an immediate priority ticket to enforcement or compliance staff.
• Industry Standards: Platforms integrated through DNV Synergi Pipeline or New Century Software (MISTRAS) help tie these field observations directly into quantitative or qualitative risk models and regulatory audit logs.

If you'd like to narrow this down, tell me:

• What is the approximate mileage and geography of your pipeline network?
• Do you currently utilize aerial patrols, a One-Call center integration, or existing fiber optics along the easement?

I can help you outline an ideal architecture for your specific risk profile.

If the goal is “see third-party activity early enough to intervene before it becomes pipeline damage,” I would not buy a generic pipeline-integrity system alone. I’d use a ROW/third-party threat monitoring platform integrated with GIS, one-call/excavation data, and your integrity-management system.

PHMSA specifically identifies excavation/third-party damage as an integrity threat and recommends integrating encroachment, one-call, inspection, and right-of-way information. Its research also recommends predictive analytics, GPS/GIS, and improved ROW monitoring to proactively identify high-risk excavations.

My shortlist

What I would actually deploy

For a U.S. gas transmission operator, I'd architect it as:

Satellite/drone change detection ↓ GIS-based proximity/risk engine ↓ One-call / excavation / permit data ↓ Threat scoring ↓ Operator work-management / dispatch ↓ Integrity Management System

The critical feature isn't simply detecting a bulldozer. It's answering:

“Is this activity close enough to this pipe, on a sufficiently susceptible segment, that someone needs to intervene now?” For example, an excavation 15 feet from a pipeline in an ordinary low-consequence area shouldn't necessarily receive the same priority as excavation crossing a high-risk segment. Your scoring should incorporate distance to pipe, depth/known cover, excavation type, equipment, prior damage, population/consequence, pipe attributes, HCA status, previous encroachments, and whether a one-call ticket exists.

That approach also fits PHMSA's expectations: operators are required to use integrated data to determine susceptibility to third-party damage and, where the threat exists, implement and monitor additional preventive measures.

One important distinction

Don't make satellite monitoring a replacement for one-call and field patrols. PHMSA notes that ROW patrols and aerial surveillance are already important controls, and unauthorized excavation can cause coating or structural damage that isn't immediately apparent.

So if I were evaluating vendors, my first pilot would be RowScan or a comparable satellite/AI ROW-monitoring product, connected to your existing GIS and work-management system. I'd test it against six to twelve months of historical encroachments and ask for measurable performance on:

• detection-to-alert latency
• percentage of true encroachments detected
• false alerts per 100 pipeline miles
• detection of excavation before physical pipeline contact
• geographic coverage and revisit frequency
• integration with ESRI/your GIS
• one-call ticket correlation
• audit trail and evidence for the integrity-management program
• automatic creation/escalation of field work orders

That last point matters: the best software isn't the one that produces the most detections; it's the one that reliably turns an ambiguous change on the ROW into an actionable integrity intervention.

What I would actually deploy
