HUNTER – Advanced Magnetic Adhesion Inspection Crawler
Hunter is a modular remote access crawler designed for cost-effective NDT ultrasonic imaging of ferromagnetic structures such as storage tanks, pressure vessels, large diameter pipes and ship hulls without the need for rope access; thus, eliminating potential risks associated with manual inspections specifically in hazardous or difficult to access terrains.
NDT Inspection Tasks:
Ease of use and deployment.
Hunters intuitive user interface allows it to be deployed and controlled by a single operator with ease. It only takes a few minutes to attach/detach the inspection packages (TOFD, B-SCAN and Corrosion mapping).
Provides Credible data.
Hunter significantly improves the quality of data collected as it moves over inspection surfaces, providing auditable results with the elimination of human error. Hunter’s ability to continuously record NDT signals also ensures instant reporting of signals in real time for data analysis by the operator.
Allows for frequent cost-effective inspection.
Hunter’s unique advantage is its ability to conduct both statutory inspection and Risk Based Inspection (RBI) guaranteeing cost savings for the asset owners. A low overall cost of inspection provides for cost effective asset management.
