Pipelines and LNG terminals are critical infrastructures where even minor incidents can lead to significant risks-threatening safety, disrupting operations, and causing costly damages. Monitoring these assets becomes increasingly complex under demanding conditions, where reliable, real-time insights are needed.
AP Sensing’s distributed fiber optic sensing technology provides a gapless pipeline monitoring solution for fast detection and accurate location of leaks and potential threats.
Understanding the Challenges
Pipeline operators and LNG terminal operators face unique and demanding challenges. Pipelines are often exposed to risks such as leaks, theft, third party intrusion (TPI), and structural stress, requiring continuous monitoring to ensure operational integrity and environmental safety. Additionally, identifying leaks or unauthorized activities over vast distances is complex and time sensitive.
For LNG terminals, handling cryogenic materials presents unique risks, including leaks in containment areas, thermal stress, and potential equipment failures. Ensuring safety during liquefaction, storage, and regasification processes is paramount.
Both industries require advanced, real-time, and non-intrusive monitoring solutions to enhance safety, minimize downtime, and comply with stringent safety and environmental standards. By addressing these challenges effectively, operators can protect assets, reduce costs, and improve operational efficiency.

Technologies Used in Process Automation & Pipeline Monitoring
AP Sensing’s pipeline and LNG terminal monitoring solution is based on three advanced technologies: Distributed Distributed Acoustic Sensing (DAS), Distributed Temperature Sensing (DTS) and Distributed Temperature & Strain Sensing (DTSS), These standalone technologies can also be combined to provide redundancy and fast leak alarm confirmation, ensuring comprehensive asset protection. Together, these technologies provide a robust, gapless monitoring solution for pipelines and LNG terminals, ensuring safety, reliability, and operational efficiency.
Distributed Acoustic Sensing (DAS)
DAS complements DTS by detecting leaks through noise, vibrations, and temperature changes associated with fluid escapes. It also enables real-time PIG tracking, identifying the progress and position of scrapers, weld interactions, and liquid accumulation. Additionally, DAS is effective for third party intrusion detection, identifying activities such as digging, pipeline drilling, or anchor dragging, as well as monitoring flow assurance.
Distributed Temperature Sensing (DTS)
DTS works by detecting and analyzing temperature variations along the pipeline. It identifies leaks by localizing hot or cold spots caused by escaping fluids. The pipeline is divided into zones to enable precise tuning and alarm thresholds for specific areas. This ensures accurate detection and localization of leaks.
Distributed Temperature & Strain Sensing (DTSS)
DTSS further enhances monitoring capabilities by detecting ground movement through strain measurement in the fiber optic cable. This makes it possible to identify potential risks to pipeline integrity caused by shifting terrain or structural stress.
Our Innovative Software Solutions
SmartVision Software
AP Sensing’s SmartVision management suite simplifies asset monitoring with a user-friendly graphical interface that integrates data from DAS, DTS, DTSS, CCTV, and other sensors into a single platform. Its advanced event visualization tools, including integrated maps, asset views, and waterfall diagrams, enable rapid decision-making and reduce response times by providing precise event locations.
Designed for seamless integration, SmartVision supports virtualized IT networks and interfaces easily with SCADA/DCS systems. With its proprietary SmartAlarm technology, the software delivers fast and reliable event classification, detecting even small leaks through advanced pattern analysis.
Alarm Management
SmartAlarm is designed to ensure Pipelines and LNG Terminals remain protected under various conditions. Basic thresholds for maximum temperature, temperature gradients, or differences to average temperatures enable reliable protection. These parameters can be customized per detection zone depending on environmental conditions and expected critical thresholds, ensuring a precise fit for each application.
Machine Learning Transient Alarm (MLTA)
Our machine learning transient alarm (MLTA) detects abnormal pipeline behaviors that would otherwise remain hidden within the temperature traces captured DTS systems. Our unique MLTA technique allows for the isolation of thermal transients along the monitored pipeline, enabling the detection of even small cold- and hotspots and triggering fast, reliable alarms.
Key Takeaways
- DTS, DTSS and DAS transform telecommunication fiber optic cables into sensing cables monitoring the entire pipeline
- Real-time and accurate data acquisition along the entire optical sensor cable
- The fiber is completely passive, immune to EMI, and non-intrusive
- Long measurement range, virtually maintenance-free for decades
