The paper presents the results of investigation of acoustic anisotropy in industrial alloy made of steel 14HGNDC after hydrogen-induced cracking (HIC) tests according to the standard NACE TM0284-2003. It was found that location and parameters of corrosion cracks with size about 20 microns can be determined by distribution and value of acoustic anisotropy. A quantitative relationship between value of acoustic anisotropy and size of corrosion cracks in the range from 60 to 6600 microns was established. The obtained results have a great importance for improving methods of hydrogen-induced cracking tests and for non-destructive testing of brittle destruction of structures in oil and gas industry by using the acoustodamage method.

A brief analytical review of the events of the VII International Industrial Forum “NDT Territory. Non-Destructive testing. Tests. Diagnostics” and the “XXII Аll-Russian Scientific and Technical Conference on Non-Destructive Control and Technical Diagnostics” held simultaneously with it. All events were held at the Expocenter Central Exhibition Complex in Moscow. The exhibition of instruments and tools of NK and TD was accompanied by a business program. Within the framework of the forum, round tables were held on topical issues of non-destructive testing and technical diagnostics. The exhibition was attended by more than 57 companies, and information support was provided by a number of news agencies, including the “Spectrum Publishing House” and “RIA Standards and Quality” (“World of Measurement” magazine). In addition to equipment for non-destructive testing and technical diagnostics, modern test equipment, testing and analytical equipment begins to appear on the stands of exhibitors. This year there was a focus on hightech solutions for engineering, metallurgy, oil and gas and other industries. The final of the competition for NK specialists and the award ceremony took place. For the first time, the “Salon of Innovations and Startups 2020” was organized at this Forum, in which representatives of 20 organizations took part. The forum demonstrated a high technical level of non-destructive testing, their metrological support, as well as certification and standardization.

Oil and gas pipelines, which transport large quantities of oil products and natural gas, are subject to pipeline failures caused by corrosion. Magnetic flux leakage (MFL) is one of the most popular non-destructive testing (NDT) techniques for the detection of pipeline corrosion. Since individual MFL is insensitive to the corrosion components that are parallel with its magnetic field, two types of MFL tools with perpendicular magnetic fields are usually employed in one inspection to detect all corrosion defects. This study applies probability of detection (POD) to quantitatively assess the detection capabilities of two individual MFL tools and their combination. Due to the characteristics of MFL inspection, this study proposes the construction of the POD model as a function of two geometric features, namely the volume and the orientation, which have a significant influence on the MFL signal response. Detection results from two MFL tools are integrated using logical OR operation to study the POD of their combination. With the proposed POD model, the minimum criteria that ensure a corrosion defect will be reliably detected by MFL tools are studied in this paper. The validity of the proposed POD model is justified on the data collected from an in-service pipeline.

The basic principle of diagnosing long-life metal structures, and pipe­lines in particular, is based on consistent and systematic measurements of certain design parameters, on detecting changes in these parameters during operation and comparing them with the original ones, and on predicting changes in these parameters. The application of technical diagnostics and non-destructive testing methods to determine the actual technical status is a regular technological operation and, as experience shows, an effective way of ensuring the tech­nical reliability and safe operation of pipelines and the gas transmission system as a whole. The methods of non-destructive testing, correlation analysis and mod­ern methods of statistical processing of experimental and reference data (artificial neural networks) were used to determine the actual state of oil and gas pipelines. Factor and regression analysis methods were used during theoretical studies. In the course of the experimental studies, the methods of experiment planning, probability theory were used.

Ensuring the safety of offshore structures is of vital importance for the reliability of oil and gas drilling rigs.Risk based inspection (RBI) is becoming an industry standard for management of equipment integrity. Theobjective of risk based inspection is to determine the likelihood of equipment failure (probability) and theconsequences of such an event. Combining the probability of an event with its possible consequencesallows determining the risk of an operation. Risk based inspection enables to optimize the frequency ofinspection, by moving from periodic inspection (based on arbitrary calendar dates) to an informedinspection program (based on equipment condition).One of the most important tools to determine the condition of the equipment, and to calculate its reliability,is the use of non destructive testing (NDT) techniques to detect cracks, flaws and defects. The probability ofdetection and the probability of sizing depend on the type of NDT method used. Combining NDTinformation on crack size and depth with fracture mechanics based damage models, allows predicting theremaining life time of a component.In this paper, the philosophy of risk based inspection is introduced and recent advances in non destructivetesting (in particular ultrasonic and electromagnetic techniques) are reviewed. Then, the use of fracturemechanics based damage models is demonstrated to predict fatigue failure for offshore structures.
