In this paper, an intelligent ultrasonic inspection device for offshore pipeline inspection and a corrosion assessment of offshore pipeline software are developed to inspect the damage state of Chinese pipelines. The main function of the inspection system is ultrasonic signal pre-processing, data acquisition, de-noising and data compression in real time. The system includes a micro-computer, transducers, pre-processing circuit, digital signal processor (DSP), Field Programmable Gate Array (FPGA), storage device, USB interface and other components. The device can sprawl through the pipeline to be inspected together with the medium being transported therein. This paper will also explain the data analysis process, the corrosion assessment of offshore pipeline software, including examples of data recorded by the ultrasonic intelligent detection device for pipeline inspection.
