Yes, they connect to any LoRaWAN or MQTT infrastructure (Kerlink, Cisco, Milesight, MultiTech, etc.) for flexible integration with existing SCADA systems.
ATEX-Certified Remote Monitoring for Oil and Gas Pipelines and Terminal Infrastructure
Pipeline and terminal infrastructure forms the backbone of hydrocarbon transportation and storage. Assets include long-distance transmission pipelines, block valve stations, pump stations, pig launcher and receiver systems, storage terminals, marine loading arms, and auxiliary safety systems. These assets operate under sustained internal pressure, experience transient hydraulic events, and are exposed to environmental stress, vibration, corrosion, and mechanical fatigue.
Monitoring challenges differ from upstream production: assets are geographically dispersed, access is often limited, and many nodes are located in classified hazardous areas. While SCADA systems provide core pressure and flow supervision, distributed condition visibility at secondary points is frequently limited by cabling constraints and I/O expansion cost.
SENSAiO provides wireless LoRaWAN monitoring sensors for valve position, pressure, temperature, differential pressure, vibration, and acoustic behavior. SENSAiO is monitoring-only. It does not replace SCADA, computational pipeline monitoring (CPM), certified leak detection systems, or safety instrumented systems. Its role is to extend field visibility and provide time-resolved evidence of mechanical and hydraulic deviations to support earlier investigation and maintenance prioritization.
The Operational Challenge
Pipeline operators must balance hydraulic stability, environmental protection, asset integrity, and regulatory compliance across extended networks. Failures are rarely instantaneous; they are often preceded by subtle changes such as:
- Progressive filter or strainer restriction
- Gradual vibration growth in pump bearings
- Repeated minor pressure transients
- Valve misalignment during pigging
- Intermittent acoustic anomalies
Because pipeline sections are widely spaced, minor anomalies can go undetected between inspection cycles. When deviations are only observed after alarms escalate, response becomes reactive, and root cause reconstruction may lack precise timing.
Operational needs typically include:
- Earlier identification of abnormal pressure behavior
- Better localization of transient events
- Remote confirmation of valve state during pigging
- Mechanical degradation visibility at pump stations
- Evidence-based investigation of suspected leak-related anomalies
The objective is not to automate control, but to reduce uncertainty in distributed infrastructure.
Why ATEX and Continuous Monitoring Matter
Pipeline block valve stations, pump stations, storage terminals, and loading facilities frequently operate in hazardous areas due to the presence of flammable hydrocarbons.
Equipment deployed in these zones must comply with ATEX Directive 2014/34/EU and, where applicable, IECEx certification schemes. Hazardous-area classification, zoning determination, and installation responsibility remain entirely with the operator.
Continuous monitoring is particularly relevant in pipeline infrastructure because:
- Pressure transients may be short-lived but mechanically significant
- Restriction builds progressively in filters and strainers
- Vibration growth precedes pump failure
- Acoustic anomalies may indicate turbulence or abnormal discharge
Monitoring does not replace engineered safeguards. It provides time-aligned data to support investigation, maintenance scheduling, and integrity review processes.
Core Use Cases for
Oil & Gas – Pipelines & Terminals
Structural condition monitoring for marine terminals
Faster anomaly investigation trigger and correlation support
Progressive restriction tracking and optimized cleaning cycles
Improved reconstruction of surge events and hydraulic stress analysis
Earlier detection of abnormal deviations and improved event localization
Reduced misalignment risk and fewer manual verification trips
Detailed Use Case Descriptions
1) Pig Launcher / Receiver Valve Position Monitoring
Pigging operations depend on correct valve sequencing. Misalignment can cause operational delays, pressure disturbances, or safety exposure. Continuous valve position monitoring provides time-stamped confirmation of opening state and supports remote verification prior to pig launch or reception. It reduces troubleshooting cycles and documentation gaps. SENSAiO does not actuate valves, override procedures, or replace operational safeguards. It provides confirmation visibility only.
2) Block Valve Station Pressure Monitoring
Remote block valve stations may be separated by several kilometers. Continuous pressure monitoring at intermediate points improves anomaly localization when deviations occur between SCADA nodes. Sustained pressure drift, unexpected transients, or pressure imbalance can be detected earlier. This complements but does not replace certified pipeline leak detection systems. It supports investigation prioritization and improved post-event reconstruction.
3) Pipeline Pressure Transient & Surge Monitoring
Hydraulic surge events may result from pump trips, rapid valve closures, or pigging operations. Monitoring transient pressure patterns supports integrity review by capturing amplitude and timing. This data can help correlate stress events with mechanical wear or joint fatigue. Monitoring does not replace surge control equipment or pressure relief systems; it provides visibility for engineering analysis.
4) Pipeline Filter / Strainer Differential Pressure Monitoring
Restriction across strainers develops gradually. Differential pressure trending allows operators to monitor rate-of-change and schedule cleaning before throughput is affected. It reduces unplanned intervention and supports maintenance window alignment. Differential pressure is an indicator and must be interpreted alongside operating conditions. It does not provide certified flow measurement.
5) Pump Station Vibration Monitoring
Pumps in terminal and transmission stations are subject to imbalance, bearing wear, and misalignment. Vibration monitoring establishes a baseline and highlights progressive deviation. Early trend recognition can justify inspection or bearing replacement before secondary damage occurs. SENSAiO does not perform automated fault diagnosis. Vibration data supports condition-based maintenance decisions.
6) Pipeline Leak Monitoring (Pressure & Acoustic)
Pressure anomalies combined with acoustic behavior changes may indicate abnormal turbulence or leak-related signatures. Acoustic monitoring can detect changes in energy patterns associated with high-velocity fluid escape. However, SENSAiO does not quantify leak rate or replace computational leak detection algorithms. It supports earlier investigation triggers and provides event timestamps for analysis.
7) Loading Arm Pressure Monitoring
Transfer operations involve dynamic pressure conditions. Monitoring supports identification of abnormal pressure fluctuations during loading or unloading. It provides additional visibility during product transfer but does not replace custody transfer instrumentation or safety interlocks.
8) Pneumatic Fender Pressure Monitoring (ISO 17357)
In marine terminals, pneumatic fenders absorb vessel berthing loads. Pressure monitoring supports structural condition tracking and inspection prioritization. It does not replace structural surveys or certification requirements.
How SENSAiO Technology Works
| Open Wireless Architecture | SENSAiO uses a LoRaWAN-based architecture to extend monitoring across long pipeline corridors and distributed stations. Wireless deployment reduces cabling requirements and allows additional measurement points without modifying core SCADA architecture. Communication parameters are configurable to balance update frequency and battery life. Network validation remains a site responsibility. |
| Sensor Design | Sensors are battery-powered industrial field devices designed for deployment in outdoor and hazardous environments. The portfolio addresses valve position, pressure, differential pressure, vibration, acoustic, and temperature monitoring. Devices measure physical phenomena and transmit data; they do not execute control logic or safety actions. |
| Data Analytics | SENSAiO integrates alongside existing SCADA, historian, and reliability systems. Monitoring data can be visualized on dashboards and referenced during integrity reviews or maintenance planning. It does not modify control loops and is not a component of a Safety Instrumented System. Integration is additive and non-intrusive to existing control architecture. |
| Data Intelligence | Data intelligence focuses on baselines, trend analysis, and deviation detection. For vibration and acoustic variables, anomaly indicators highlight measurable changes from established norms. These indicators require engineering interpretation and do not constitute automatic diagnosis. |

Proven ROI and Field Results
In pipeline and terminal environments, ROI is primarily driven by reduced uncertainty and improved timing of intervention.
Deployment may contribute to:
- Reduced non-essential field verification trips at remote valve stations
- Earlier identification of filter/strainer restriction progression
- Improved pump maintenance scheduling through vibration trending
- Faster anomaly localization during suspected leak investigations
- Improved reconstruction of pressure transient events
- Reduced troubleshooting time during pigging operations
These benefits depend on workflow integration, alert ownership, and review discipline.
Operators may observe:
- 10–30% reduction in non-critical verification trips at remote stations
- 15–35% earlier detection of restriction trends compared to inspection-only approaches
- 10–25% increase in maintenance planning lead time for pump equipment
- 20–40% faster investigation cycle time when acoustic and pressure timestamps are available
- Improved anomaly localization resolution between major SCADA nodes
These ranges are indicative and not guaranteed. SENSAiO does not prevent leaks or eliminate mechanical degradation. It supports earlier evidence-based decision-making.

Does SENSAiO improve regulatory compliance?
SENSAiO itself is not a compliance system. It provides monitoring data that may support integrity documentation, investigation records, and maintenance evidence. Regulatory compliance remains governed by operator procedures and certified systems. Monitoring data can improve traceability but does not replace mandated detection or safety mechanisms.
Can valve position monitoring reduce pigging errors?
Valve position monitoring provides time-stamped confirmation of opening state prior to pigging operations. This reduces uncertainty and shortens troubleshooting when misalignment occurs. It does not replace procedural controls or safety systems. It provides operational visibility to support correct sequencing and documentation.
Is wireless monitoring reliable across long pipeline distances?
Wireless performance depends on terrain, antenna positioning, and network validation. LoRaWAN enables extended coverage, but deployment should include coverage assessment. SENSAiO provides configurable transmission intervals to balance responsiveness and battery life. It complements SCADA rather than replacing core telemetry.
How does vibration monitoring improve pump reliability?
Vibration trending highlights baseline deviation that may indicate imbalance, looseness, or bearing wear. Earlier recognition can extend planning lead time for inspection or component replacement. SENSAiO does not perform automated fault diagnosis or predict exact failure timing. Engineers interpret vibration trends within operational context to support condition-based maintenance.
What decisions can differential pressure monitoring support?
Differential pressure trends across strainers help identify restriction progression. The key value is recognizing sustained rise and rate-of-change to schedule cleaning before throughput or pump efficiency is affected. Differential pressure monitoring does not certify flow and does not diagnose fouling type. It supports maintenance planning decisions rather than replacing inspection programs.
How does pressure monitoring improve event reconstruction?
Pressure monitoring captures transient amplitude and timing between main SCADA nodes. When a surge, valve closure, or pump trip occurs, distributed pressure timestamps allow more precise reconstruction of the sequence. This improves root-cause analysis and mechanical stress review. SENSAiO does not replace surge control systems; it provides additional visibility that supports engineering interpretation.
Can acoustic monitoring confirm a pipeline leak?
Acoustic monitoring detects changes in sound energy that may correlate with turbulence or high-velocity fluid escape. However, acoustic signals alone do not confirm leak presence, location, or rate. Interpretation requires correlation with pressure data, operating conditions, and engineering analysis. SENSAiO provides anomaly indicators to support investigation; it does not replace certified leak detection methodologies or field verification procedures.
Does SENSAiO replace certified pipeline leak detection systems?
No. Certified leak detection systems (e.g., CPM or mass balance models) remain the primary regulatory and operational tools for leak detection. SENSAiO provides distributed pressure and acoustic monitoring that may support earlier anomaly identification or event correlation. It does not perform mass balance calculations or guarantee leak detection. Its value lies in providing time-stamped field data that complements existing systems and supports investigation workflows.
