With ever increasing global demand and depleting resources for fossil fuels, oil and gas industry is now positively looking for advanced robotic solutions to increase their productivity and safety. With time easy resources of the fossil fuels are…
This paper proposes a microwave non-destructive testing (NDT) method to detect and estimate the volume fraction of fresh or saline water in natural gas pipelines. The gas pipe is modelled as a waveguide that is filled with gas and different…
This work introduces a clamp-on narrow-band passive ultrasonic isolator that extends the gas density / pressure Pareto frontier for non-invasively polling the interior of gas-pressurized steel pipeline. The isolators enable an ultrasound-based…
Problems of conventional ultrasonic techniques with respect to detection of scales in petroleum pipelines are analysed. The development of mathematical models to extract the characteristic features from ultrasonic scans for detecting the type and the…
