Detecting Wet H2S Damage with a Novel Robotic Technique

Wet H2S damage can cause sudden and catastrophic equipment failure, resulting in the loss of containment and/or personnel and impacting operational costs due to environmental remediation and reduced productivity. Hydrogen induced cracking (HIC), stress oriented HIC (SOHIC), and sulfide stress cracking (SSC) are regularly misclassified as minor cracks, laminations, and base metal inclusions or completely undetected by NDT techniques. But, a novel robotic inspection technique offers unparalleled productivity and resolution to identify damage at the earliest stages. Tri-Lateral Phased Array (TriLat) is an ultrasonic testing method for the on-stream inspection of fixed equipment in wet H2S service. Its unique probe design, featuring multidirectional focalization customization and two axis resolution, generates a granular data set that has resulted in the positive identification of damage in a number of field applications.

Inspectioneering has teamed up with Chase David, Director of Operations at Gecko Robotics to discuss the complexities of wet H2S damage, the current industry solutions for identifying it. Then, he will dive into the development of TriLat, how it works, and case studies of successful field applications.
