ABSTRACT
The pressure drop in the protected section of the pipeline is either the result of an external wave of flow velocity change, or of a leak. In the first case, this event can be ignored; in the second one, it is necessary to report the leak and determine its coordinate. Reliable detection and localization of leaks is often complicated by noticeable pressure rattling («noise») and transient mode at the nearest pumping station. To solve the problem in these conditions, a method is proposed. According this method, the pressure trend from one of the sensor is shifted in amplitude and time so that in the absence of leakage the trends on both end sensors almost coincide. For external waves from a «noisy» pumping station synchronized trends should almost coincide, but in case of leakage, a gap may appear between the charts. The passage of waves through the sensors corresponds to the start moments of the discrepancy and subsequent convergence of the trends. The application of the method is illustrated on the real examples.
KEYWORDS: Leak detection system in oil pipelines, pressure drop wave, leak localization, transient mode, pressure rattle, amplitude-phase synchronization method, convergence and divergence of synchronized pressure trends.

ABSTRACT
An extremal method for determining the location of a leak in a pipeline is considered. One of the most critical tasks in ensuring the uninterrupted operation of pipeline systems is the timely acquisition of information about both the condition of the pipeline and the fluid being transported. The objective of the study presented in this article is to develop a rule for predicting the leak location based on measured pressure gradient values at sensor installation points spaced at equal intervals. Based on the gradient method, an extremal approach for leak detection in pipelines has been developed. The implementation methodology of the proposed method is presented.

ABSTRACT
The article presents the results of testing the mathematical model for calculating the volume and time of liquid release from a pipeline using data obtained from an experimental bench-scale installation belonging to the Scientific and Technical Center of the Research Institute Transneft. As a result of testing, it was found that the error in calculating the liquid release time and volume was 7.9% and 3.15%, respectively. Thus, the mathematical model developed by the authors of the article adequately takes into account hydraulic processes during oil release from a pipeline and can be recommended for use in the practice of oil and oil product pipeline transportation.

ABSTRACT
The article shows the possibility of increasing the useful volume of a typical vertical steel tank (VST) by replacing the intake-dispensing spigot with the receiving and dispensing device (RDD) in the first belt of the tank and the generator of high-fold foam (GHF) in the upper belt with a foam generator of medium foam generation (MFG), cut into the roof of the tank. The methodology of determination of quantitative characteristics allowing to calculate the components of the tank volume is described. A mathematical model of funneling in the case of liquid flow from a tank with a lateral bottom hole is used. The achieved results meet the tasks of realization of actual national programs of resource saving, ecological safety and the concept of “lean production”.

ABSTRACT
In this article, the authors consider deformations for support structures in the permafrost conditions of the Yamburg field based on the sites of the complex gas treatment plant and the booster compressor station. The studies have shown that the main cause of deformations is the change in the level of the permafrost roof, which is accompanied by an increase in the thickness of the seasonal thawed layer of soil relative to the calculated values, which is approximately two to four times higher than expected. This process causes significant shifts in the soil masses, which negatively affects the stability of the support structures. To prevent the destruction of fundamental structures and minimize the negative consequences, the authors propose a set of measures aimed at stabilizing the foundation soil and reducing the risk of structural deformations. The combination of the proposed methods will significantly reduce the risk of accidents related to the integrity of support structures, extend the service life of equipment, and ensure the safety of oil and gas production facilities in the extreme natural and climatic conditions of the Arctic region.

ABSTRACT
Fault detection and condition monitoring of industrial equipment is essential to ensure efficient, reliable and safe operation. Traditional approaches such as vibration (10 Hz – 10 kHz) and acoustic emission (20 kHz – 1 MHz) analysis are highly effective, but are often limited by specialized sensors, high cost and complexity of setup. This review examines the potential of airborne sound-based diagnostics (16 Hz – 20 kHz) as an alternative or complementary method that can utilize standard microphones and consumer-grade hardware to detect various mid-stage equipment faults. Considering a review of the current literature, key challenges are highlighted, including strong interference from ambient industrial noise, a more limited ability to capture early (incipient) faults compared to high-frequency acoustic emission, and the need for robust fault feature extraction and optimal selection of machine learning models for real-world applications. Recent advances in noise filtering, wavelet transforms and classification based on artificial neural networks demonstrate the growing viability of sound frequency based fault detection methods. Comparison with vibration and acoustic emission methods shows that airborne sound can provide an optimal cost/defect stage ratio, especially when early detection of microdefects is not of paramount importance. The review concludes by highlighting future research directions, including fusion of data from multiple sensors, enhanced integration of advanced deep learning approaches with improved signal processing, and real-time adaptive monitoring, which will enable scalable, cost-effective, and affordable solutions for predictive maintenance in various industries, including oil and gas and petrochemicals.

ABSTRACT
The most important regulatory and technical requirements for hazardous industrial facilities remain ensuring reliable, accident-free and safe operation. The article considers the effect of foundation settlement of a main gas pipeline valve station operated in complicated engineering and geological conditions (zone of intermittent and massive-island distribution of permafrost) on the stress-strain state of welded joints of a ball valve. Foundation settlement is monitored annually in the course of geotechnical monitoring of the spatial position of key control points of the linear section of the main gas pipeline. To study and analyze the stress-strain state of the section under consideration, a three-dimensional model was developed for it with loss of bearing capacity of the foundation soils. To assess the SSS of the valve station, the «crane station-support-soil» system was simulated using finite element analysis in the Ansys software package.

ABSTRACT
The air environment of settlements located in the zone of negative impact of open coal mining is subject to pollution near the places of extraction, storage and loading. These processes are aggravated by the sharply continental climate and the peculiarities of its formation in the conditions of Transbaikalia. The direction of the wind rose depends on the conditions of urbanized geosystems of intermountain basins, which directly further forms the direction and area of the coal plume. In these conditions, we are talking about rural and urban settlements falling into the zone of its impact. In the special conditions of Transbaikalia, where in intermountain basins these conditions are similar to a «wind tunnel», the coal plume mainly acquires an elongated shape and can extend for tens of kilometers. The population of these territories is exposed to additional negative impact associated not only with the conditions of the sharply continental climate, but also with the air environment contaminated with coal dust. The author proposes a set of measures to reduce the amount of dust in the air of such settlements. These activities are related to new methods of dust suppression in open-pit coal mining areas, specifically in coal storage and loading areas, and the construction of protective forest belts separating these areas from populated areas.
