Guided Ultrasonics Ltd. (GUL) is leading a transformative shift in pipeline inspection by evolving Guided Wave Testing (GWT) from a periodic screening method into a proactive, real-time integrity management solution. GUL’s advanced systems are leveraging guided wave technology to provide continuous, 24/7 monitoring of critical assets, enabling a move from reactive inspections to predictive maintenance.
GWT is a form of ultrasonic non-destructive testing (NDT) that uses low-frequency waves to inspect long structures, like pipelines, from a single point. These waves are "guided" by the structure's geometry, allowing them to travel tens of meters to detect defects in inaccessible or buried areas. To overcome the traditional limitations of this method, such as signal distortion from complex geometries and signal attenuation from soil or thick coatings, GUL has developed innovative hardware, software, and methodologies.
A core innovation is GUL’s leap towards autonomous guided wave monitoring. Instead of relying on technicians for scheduled inspections, the company now offers permanently installed, dual-function guided wave sensors that send real-time data to a cloud-based platform, Monitoring Studio. This system continuously tracks wall condition over time, alerting operators to changes as they occur. The capability to receive real-time alerts on issues such as corrosion growth allows for faster decision-making and preventive interventions before a leak or failure can happen.
GUL’s technology has proven its value in real-world applications. In one instance, a system installed on a process flare line detected a non-corrosive buildup of solid material, enabling the operator to schedule a cleaning before a process disruption. In another case, the system detected active external corrosion on a crude oil jetty line beneath a service structure, allowing for timely repairs that prevented a potential environmental incident.
Beyond its technological advancements, GUL is committed to ensuring industry-wide proficiency through its certified GULT program, which trains and certifies technicians in guided wave theory and field applications. This investment in knowledge and expertise supports the broader adoption of real-time monitoring, challenging asset owners to embrace continuous insight over periodic snapshots.
