How AI And IoT Are Used to Monitor and Detect Leaks in Pipelines

19-04-2022 Aesthetix

While leak detection systems (LDS) have been used by operating companies in upstream, midstream, and downstream oil and gas for decades, new regulations, rising concerns about pipeline integrity and cybersecurity, and the availability of several powerful new technologies have sparked increased interest in these solutions among end-users. This is encouraging for the market as a whole in the future years. To increase pipeline safety, availability, and security, today's increasingly software-based leak detection systems include advanced automation as well as new, disruptive technologies like Predictive Analytics, Artificial Intelligence, and the Internet of Things (IoT).

AI and IoT Pipeline Monitoring Systems

Pipeline spills can have far-reaching repercussions, including safety concerns, environmental risks, property and reputational damage, as well as the financial expenses of regulatory fines and clean-up. Pipeline operators need reliable pipeline leak detection systems to identify pipeline leaks rapidly, correctly locate leaks, receive real-time notifications, and perform efficiently in challenging operating situations.

AI technology has enormous potential for monitoring solutions, with the possibility to expand conventional technology and revolutionise pipeline maintenance. Like SCADA,  remote-controlled operations Hence, Artificial Intelligence (AI) can be used to analyse patterns and predict and prevent pipeline leaks and ruptures, improving both safety and profitability. For years, pipeline operators have used real-time data analysis (RTDA), but this typically results in a large amount of clustered data along the length of the pipeline. Advanced analytics and algorithms help to understand the "how, when, and what" of potential (and actual) leaks in any given situation and can help optimise operations in the oil and gas industry and reduce failures with immediate effect.

Advantages of IoT and AI-Based Pipeline Leak Detectors

  • Pipeline breaches are rapidly detected and the damage is minimised by decreasing product loss.
  • When a leak occurs, it provides critical information regarding the size, location, and amount of goods lost.
  • Monitors your whole pipeline network with precise data and detects pipeline breaches early to avoid any potential tragedies.
  • Protect people, property, the environment, and your reputation.
  • Tracks pipeline ruptures and corrosion and ruptures caused by abrasive elements

4 Major ways in which IOT and AI sensors enhance pipeline leak detection

Extended leak detection systems

Existing pipeline telemetry systems such as SCADA networks that monitor for leaks using pressure and flow analysis, can benefit from IoT and AI sensors. Low-power IoT sensors, which are frequently powered by solar panel attachments, can collect a variety of operational data.

These sensors can be used to supplement the inside pipeline monitoring provided by a SCADA system. Acoustic or ultrasonic sensors, for example, can listen for anomalous sound waves that could indicate leaks or crack start and growth.

Methane gas detectors are a less complicated way of detecting leaks. Abnormal methane levels can warn pipeline operators, allowing them to locate the location of a leak. Internal pressure sensors can sometimes produce false positives, thus a wide fleet of sensors mounted at regular intervals can improve leak detection and prevent false positives.

Improved trend predictions and leak forecasting

Better leak data can lead to more accurate forecasting models. Because of the speed and quantity of IoT data, new forecasting and trend prediction models can identify actions and events that are likely to lead to pipeline failures. A big data analytics system can evaluate data collected from a fleet of IoT and Ai devices. To find novel patterns in failure events, both real-time and historical sensor data can be studied. These can aid pipeline operators in developing more accurate forecasting models that can spot leaks and damaged earlier.

This application is similar to predictive maintenance in pipelines, which is one of the most prevalent IoT applications. It forecasts machine failure or anomalous behaviour using operational data from IoT and AI sensors.

Accelerate troubleshooting and responses

Since pipeline integrity can be monitored 24/7, any abnormalities or deviations can be detected quickly. While a pressure reduction may appear to indicate a leak, other sensor metrics might help detect pipeline structural flaws much earlier - before a major spill or tragic explosion. Ultrasonic and acoustic sensors, for example, can detect abnormal sound waves that signal fracture initiation, development, and delamination. Magnetic sensors can also detect changes in pipeline wall thickness caused by corrosion.

Smart sensors can detect and accelerate critical actions by transmitting not just the location and degree of early-stage damage. The time between failure and remediation must be as short as possible to minimise material losses and contamination caused by discharged goods. Early detection of defects also facilitates repair, resulting in lower maintenance costs and downtime.

Establishing the foundation for self-optimizing and autonomous pipeline management

IoT and AI sensors and remote controls may be used to develop self-optimizing pipeline management systems in the near future. A pipeline management system powered by AI and IoT can automate most or all phases in the traditional pipeline leak reporting procedure. Alerting pipeline operators, opening or closing valves, contacting government agencies, and assigning personnel to the point of failure are all part of this process.

IoT-controlled pipeline valves and terminals, as well as other technology, enable remote control of crucial pipeline infrastructure. These controls, when combined with IoT and AI sensors, allow the pipeline system to effectively monitor and manage itself, altering gas flow as needed to reduce damage or the effects of the leak.

The advantages of using AI and IoT for distant intelligent infrastructure are obvious, with the capacity to improve performance, monitor integrity, and minimise both safety and environmental risk. The future of pipelines is here, and it involves combining intelligent algorithms with an end-to-end solution that integrates sensors with real-time edge computing for asset and activity profiling.
