Corrosion Assessment of Offshore Oil Pipeline Based on Ultrasonic Technique
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, tr...
متن کاملUltrasonic Thickness Inspection of Oil Pipeline Based on Marginal Spectrum of Hilbert-Huang Transform
Measurement of pipeline wall thickness is one of the main contents of nondestructive inspection on offshore oil pipeline. A novel approach based on the marginal spectrum of the Hilbert-Huang transform is proposed for ultrasonic echo signal processing. The demodulated ultrasonic echo signal contains the thickness information of pipeline wall, which is an approximately periodic signal. The margin...
متن کاملIn-Line Inspection using Ultrasonic Technology
Ultrasonic (UT) is currently the most accurate and reliable In-Line Inspection (ILI) technology available in the market. These UT ILI Tools will record data while travelling through the pipeline from Launcher to Receiver. In most cases, the Pipeline Operator does not need to make major adjustments to their pipeline's normal operating conditions when conducting the inspection survey. Piezo-elect...
متن کاملFuzzy consequence modelling of hydrocarbon offshore pipeline
The traditional event tree analysis uses a single probability to represent each top event. However, it is unrealistic to evaluate the occurrence of each event by using a crisp value without considering the inherent uncertainty and imprecision a state has. The fuzzy set theory is universally applied to deal with this kind of phenomena. The main purpose of this study is to construct an easy metho...
متن کاملCalibration Method Study of Ultrasonic Thickness Gauge
Since the invention of ultrasonic examination technology, the ultrasonic thickness gauge has been widely used and playing an important role in many field, such as service inspection of pipeline and pressure vessel, in the quality control of massive construction project, the dimension measurement of complicated-shaped mechanical components and so on. With the rapid growing of our country economy...
