ABSTRACT
Modern requirements for ensuring the reliability and durability of main pipelines dictate the need to review and adapt existing methods for calculating their stress-strain state. This paper examines various approaches to calculating the strength and stability of pipelines used in different countries. The analysis shows that, despite some differences in assessing factors such as bending radii and temperature stresses, the basic principles of calculation remain similar. At the same time, it is worth noting that the current standards do not fully take into account the features of long-term operation of pipelines, which emphasizes the need for further improvement of the regulatory framework.
KEYWORDS: main pipelines, accident statistics, pipelines with a long service life, the intensity of accidents.

ABSTRACT
The work is devoted to determining the numerical values of the similarity criterion of non-stationary processes (the Strouhal number) depending on the characteristic parameters of the flow when flowing through a tee into a side branch. It has been experimentally confirmed that the range of frequencies of hydrodynamic vibrations directly depends on the flow rate of the working medium. With a decrease in the latter, the range also decreases. In tees, with a sufficient flow rate of liquid, vortex formation occurs, which is the cause of forced oscillations. The numerical values of the Strouhal number, characterizing hydrodynamic phenomena in non-stationary flow modes, obtained depending on the Reynolds number, can help in predicting the characteristic frequencies of oscillations of complex pipeline systems.
KEYWORDS: vibration, vortex formation, hydrodynamics, T-joint, process pipelines, Strouhal number.

ABSTRACT
Currently, in pipeline transportation of energy resources, a pressing issue is monitoring the location of in-pipe devices during pipeline cleaning and diagnostics procedures. Most projectile tracking methods and means used in pipeline transportation have low characteristics in terms of location accuracy, which leads to an increase in the time it takes to find stuck in-pipe device, which in turn increases the costs of performing work. The article presents the results of a systematic review of existing and prospective methods of in-pipe devices tracking, evaluates their advantages and disadvantages, and proposes a classification of these methods. The obtained results of the work can be used in practice to select the optimal method of in-pipe devices tracking, as well as to develop new effective systems that will eliminate the disadvantages of existing methods.
KEYWORDS: in-pipe device, control means, inspection tool, cleaning tool.

ABSTRACT
When pumping gas condensates, it is necessary to provide a single-phase flow. The complication is the instability of the condensate pipeline operation, as the productivity and thermodynamic parameters of pumping change. The article discusses the problems of pumping unstable condensate through a low-temperature pipeline. The possible pumping temperatures and pressures are shown. A phase diagram is calculated based on the composition of the unstable condensate. Based on the results of the analysis of operational indicators, the temperature state of the soil, and the phase state of the condensate, it is proposed to increase the pumping temperature to reduce the heat exchange of the low-temperature pipeline with thawed and waterlogged soil to prevent secondary frost heaving.
KEYWORDS: unstable condensate, low-temperature pipeline, phase state, permafrost soil.

ABSTRACT
The article describes the process of experimental evaluation of the sensitivity of pressure sensors from various manufacturers with different service life based on verification of their readings on a hydraulic stand. The basis of the verification method is the assessment of the readings of pressure sensors at the time of their sudden loading or removal of the load. The minimum possible disturbance that the pressure sensor is working on is recognized by its sensitivity. Depending on a certain average sensitivity of the sensors, the minimum possible detectable leakage rate is determined for each of the diameters normalized for main oil pipelines. In addition, the article provides optimal settings for filtering data when working with a mathematical model, which is based on detecting leaks on main oil and petroleum product pipelines using the method of negative pressure waves and scanning pressure waves.
KEYWORDS: sensitivity of pressure sensors, pressure waves, oil trunk pipeline, leak, criminal tie-in, mathematical model.

ABSTRACT
This article discusses the main properties and features of the formation of asphalt-resin-paraffin deposits in pipelines and oil production equipment, as well as methods for removing and preventing the formation of ARPD. To date, several well-known and frequently used methods of sediment control are most actively used, but the variety of development characteristics and the difference in properties of the extracted liquid obliges the selection of individual approaches or the development of new tools. As a result, these compounds are effective in individual fields and only in certain technological areas. In this article, in order to disclose these issues, the results of the analysis, systematization and classification of known methods and means aimed at combating asphalt-resin-paraffin deposits in pipeline transport and oil production are presented.

ABSTRACT
The article presents a review of the causes and conditions for the formation of gas-air accumulations in pipelines and examines their negative impact on the operational performance of oil and petroleum product pipelines, exemplified by the increase in the hydraulic resistance coefficient of a pipeline section containing a gas phase. The methods and conditions for their removal are demonstrated. The article proposes a new concept for the removal of gas-air accumulations from oil and petroleum product pipelines by pumping a special «removal batch» of oil or petroleum product through the pipeline, containing the necessary concentrations of special chemical reagents for removal. The application of the proposed method for removing gas-air accumulations can be used in cases of partial pipeline loading at low flow rates between pipeline cleanings or for sections that cannot accommodate cleaning devices.

ABSTRACT
The article addresses the challenges of selecting materials for subsea pipelines in the context of modern technological and environmental challenges. Particular attention is given to the analysis of the corrosion resistance and mechanical properties of steels used in the construction of subsea pipelines. The study includes a classification of various types of steels based on their operational characteristics, examines the main types of corrosion occurring in aggressive marine environments, and proposes protection methods, including cathodic protection and the use of anti-corrosion coatings. Based on the analysis, scientifically grounded recommendations are developed for selecting the most suitable materials to ensure the reliability and durability of subsea pipelines under challenging operating conditions.
KEYWORDS: subsea pipelines, corrosion resistance, carbon steel, stainless steel, cathodic protection, anti-corrosion coatings, operational conditions, mechanical properties, durability, energy security.

ABSTRACT
The article describes the development of the field of insulating materials for corrosion protection of pipelines. Methods of studying the performance characteristics of protective coatings including those based on innovative insulating material of asphalt-resin oligomer – Asmol are considered. Evidence of its chemical bonding with the metal surface due to the presence of functional groups in the composition of Asmol, confirmed by gravimetric studies, is given. The data on the effect of self-repairing of insulating coating on the basis of Asmol are given, with calculation of the parameter characterizing this effect
KEYWORDS: anticorrosion coatings, insulation, asmol, chemical adhesion, self-repairing effect.

ABSTRACT
The giant collapse-explosive eruption of the northernmost andesitic volcano in Kamchatka, Shiveluch, on November 12, 1964 was associated with tension conditions in the upper mantle and earth’s crust of Kamchatka, favorable for the rise of large portions of magma to the surface of the earth. Before the eruption, a large swarm of volcano tectonic earthquakes was noted: about 500 events with M = 2–5; (Mw up to 5.0–5.2) with rupture lengths of up to 500 m. About 10 of the strongest events were felt in the village of Klyuchi at a distance of 45 km with a strength of 3–4 Mercalliballs. During the last 5.5 hours, the seismic power reached an unprecedented 200 MW, which is comparable to the capacity of all the power plants in Petropavlovsk-Kamchatsky. This was noted for the first time during instrumental observations of the volcanoes in Kamchatka. Fresh magma rose in the central feeding channel of the volcano, filled with an impermeable viscous lava plug; its summit was a huge massif of older lava domes with steep slopes (a closed system). That is why no visual increases in activity were noted before the eruption. Volcanic earthquakes were generated by a regional tectonic stress field and initiated by an increase in pore fluid pressure during the interaction of andesite magma with an aquifer. Three days before the eruption, hot magma entered the flooded, highly permeable for fluids base of the lava dome massif, filled with collapse material from the previous major eruption of 1854. There was a sharp increase in pore pressure in the environment, and the seismic process acquired an avalanche-like, catastrophic character. Large volcanic earthquakes disrupted the continuity of the base of this massif and contributed to its collapse under the action of gravitational forces. The decrease in lithostatic load led to accelerated movement of magma to the bottom of the large crater formed and to the beginning of the eruption. 6 months before its beginning,the eruption was foreseen (P.I. Tokarev), but it was difficult to make a short-term forecast due to the unusual short duration of the main phase of the earthquake swarm (99% of their energy was released within 11/4 days before the collapse and eruption). After the eruption, there was a complete unloading, the earthquakes ceased and the volcano remained quiet for 16 years, until 1980.
KEYWORDS: andesitic volcano, magmatic intrusions, landslide-explosive eruption, mechanism of volcanic earthquake source, pore fluid pressure, seismological precursors of volcanic edifice collapse.
