Comprehensive Study to Understand Longitudinal ERW Seam Failures |
Threats and Integrity Management -- Pipeline Testing, Analysis and Repair
|
Under Development |
| Description: | The project had the objective of integrating industry and PHMSA data to quantify vintage seam failure statistics, focusing on ERW pipes. Based on an understanding of longitudinal ERW seam failures, the analysis aimed at assessing the effectiveness and effects of ILI inspection tools, hydrostatic... | ||

Continuous Open Path Methane Monitors |
Damage Prevention and Mitigation -- Leak Detection
|
Under Development |
| Description: | Continuous open path monitors for methane that utilize laser absorption spectroscopy. Laser absorption spectroscopy works by directing an infrared laser to a reflector that returns a signal to the monitor’s detector. The infrared laser signal is swept across an absorption peak, an electromagnetic... | ||

Development and Field Testing of a Highly Sensitive Mercaptans Instrument |
Threats and Integrity Management -- Pipeline Testing, Analysis and Repair
|
Under Development |
| Description: | The project developed and field-tested a portable, low-cost instrument for the measurement of hydrogen sulfites and mercaptans, which are found in natural gas, renewable natural gas, biogas, and landfill gas. The instrument allows the detection and measurement of such compounds at the part per... | ||

Development of Tools for Assessing the Severity and Life of Dent Features |
Threats and Integrity Management -- Pipeline Testing, Analysis and Repair
|
Under Development |
| Description: | This project used elements of the previously validated dent assessment tool to develop a mechanical damage assessment strategy, validate it and ultimately develop an easily applied mechanical damage fatigue life assessment tool. The existing BMT “plain” dent assessment model was extended to consider... | ||
 |
Differential-Absorption Lidar (DIAL) Methane Monitor |
Damage Prevention and Mitigation -- Leak Detection
|
Commercial Product |
| Description: | Methane Monitor is a differential-absorption lidar (DIAL) methane detection system that uses two lasers of slightly different infrared wavelengths to map the ground and measure atmospheric methane. Methane strongly absorbs one of the wavelengths (at about 1,645.55 nm, the “on-resonance beam”) and... | ||

Dynamic Response Spectroscopy (DRS) |
Threats and Integrity Management -- Anomaly Detection and Characterization
|
Commercial Product |
| Description: | The Dynamic Response Spectroscopy (DRS) is an ultrasonic inspection technique for corrosion mapping through challenging coatings, such as composite wraps, where existing ultrasonic techniques are ineffective. This technique has been designed to look through the composite repairs to measure the... | ||
 |
Eddy Current-Based Crack Detection Sensor for Unpiggable Transmission Lines |
Threats and Integrity Management -- Anomaly Detection and Characterization
|
Under Development |
| Description: | The PHMSA-funded project develops and tests an Anisotropic Magneto Resistive (AMR) Eddy Current (EC)-based sensor for live, in-line inspection of 6 to 8-inch diameter, unpiggable natural gas pipelines. The sensor system has been proven through a separate feasibility study to function with a ... | ||
 |
Electromagnetic Sensors to Quantify Strength and Toughness in Steel Pipelines | Under Development | |
| Description: | G2MT technologies provide services for integrity inspection of pipeline stresses and conditions (see picture). The project developed a nondestructive testing technology to rapidly evaluate pipeline mechanical properties. The strength and toughness of the steel pipelines determined from the... | ||
 |
Electromagnetic Strategies for Locatable Plastic Pipe |
Damage Prevention and Mitigation -- Pipe Locating
|
Under Development |
| Description: | The project investigated two strategies for fabricating plastic pipe that are intrinsically responsive to electromagnetic interrogation from the surface. The first strategy is to incorporate encapsulated magnetic nanoparticles (see figure) that will exhibit a strong response to EM radiation from... | ||
 |
EMAT Sensor for Small Diameter and Unpiggable Pipes |
Threats and Integrity Management -- Anomaly Detection and Characterization
|
Under Development |
| Description: | The project is co-funded by PHMSA and OTD to develop a device which can be pulled via an umbilical through pipe samples and uses Electromagnetic Acoustic Transducer (EMAT) to detect and quantify longitudinal cracks. A laboratory bench-scale unit has been successfully completed and tested in... | ||
