Quest TruTec's vessel assessment program combines a laser mapping technique with a visual inspection via video camera to detect defects. Before laser measurement technology, bulge detection and measurement required internal scaffolding and personnel entry into the drum. The internal visual inspection by Quest TruTec's video camera equipment fulfills the compliance requirements for internal inspection. Cracking detected within welds or base material can be further examined utilizing Automated Ultrasonic Testing to quantify the extent of crack depth.
