Remote drone inspection technology is growing in sophistication and capabilities. In the recent inspection of a 19.4 meter high oil tank on board a vessel in Norway, the video shot by the drone was interpreted in real-time by an algorithm to detect cracks in the structure. It marked the latest step in a technology qualification process that promises to make tank inspections safer and more efficient. The inspection was carried out by Scout Drone Inspection and DNV GL, who have been working together to develop an autonomous drone system to overcome the common challenges of tank inspections to reduce costs and out-of-service times.
