     Annotation. There are health, safety and environmental (HSE) risks in enterprises. These risks can be harmful to people and the environment. HSE experts help improve safety, especially in the oil and gas industry, where hazards exist during activities such as exploration, drilling, mining, etc. Workers may be exposed to dangerous gases such as hydrogen sulfide. To ensure universal safety, we need three important things: proper handling of these gases, careful planning, and ensuring proper employee training. Workers in the oil and gas industry can also get sick due to exposure to chemicals that can cause problems with the lungs, skin and other organs. Noise at work can lead to hearing loss. There is a risk of serious injury and death, especially for inexperienced workers and workers under poor supervision. To make things safer, we need to find and understand these risks and figure out how to control and deal with them. This research is important because it helps us learn how to better manage these risks. It examines the challenges and solutions to make the workplace safer for workers and the environment.

Annotation. One of the most effective ways of monitoring is dynamometry. Dynamograms are used to diagnose and monitor the operation of the recognition of rod-well pumping units  (RDPU). A new approach to detecting and detecting failures, malfunctions in the operation of the RDPU system, excluding the human factor. The use of Fourier descriptors for the recognition of dynamometric maps and machine learning techniques for the classification of various pump conditions is proposed. With the help of the Fourier descriptor, it is  possible to predict and diagnose malfunctions of the downhole pump. These descriptors simplify, normalize, and describe each map well. The proposed method is trained using data from real dynamometric maps.

Keywords: rod-well pumping unit (RDPU), monitoring, failure, malfunctions, dynamometric map, dynamogram, Fourier descriptors, machine learning technique, model, recognition algorithm, data analysis.

Abstract. Optimization of the network of transformation centers is one of the conditions for the effective functioning of the macro-logistic system. Acting as links in logistics chains, transformation centers perform the most important functions of promoting material flows between the elements of production processes, commodity circulation and consumption. The article studies and reveals the role of transformation centers, which implement the most important tasks of mutual cooperation of trunk and local modes of transport.  The stages of logistic approach in choosing the variant of transformational centers location have been investigated. It has been determined that the transformation centers, being the basis for the creation of macro-logistic transport and storage systems of the corresponding level, perform the functions necessary to smooth the unevenness, inaccuracy of production, consumption and modes of transport turnover. The logistic concept which assumes the necessity of transformational centers as transport terminal complexes, warehouse complexes to create positive results of interaction of factors characterizing optimization of processes of advancement of material flows in logistic chains has been analyzed.  The results of the study showed that in maritime transport, the main factor in the development of transport container terminals, as varieties of transformation centers - is the formation of complexes of means of transportation of centralized systems of movement of goods.  Currently, the system of container transportation is among the most rational methods of technology and organization of multimodal cargo transportation. The concept of this system is based on the fact that it is proposed to transport cargo flows in a single cargo unit-capacity mixed modes of transport. In the conditions of functioning of the local transformation center, in addition to the implementation of complex logistical operations for the processing of material flows, operations for the development of preparatory processes of products for production consumption in the end are performed. This determines the representation of transport and warehouse systems of transformation centers as varieties of flexible production and logistics systems.

Key words: transformation centers, material flow, transport and storage system, logistics chain, container terminal, automated container terminal management systems.

Abstract. This paper investigates in detail the aspects of supersonic gas jets application in the process of thermal destruction of rocks. The main attention is paid to various aspects of heat transfer, which is key in the use of such methods. The main thermodynamic parameters of a high-intensity gas heat carrier in interaction with rocks are considered. Important characteristics are the heat transfer coefficient from the gas jet to the rock, the effective gas temperature at the rock surface and the specific heat flux. In order to achieve a more accurate mathematical description of the process of thermal destruction of rocks, the authors present a model of the interaction between the gas jet and the rock. They draw attention to the importance of the correct choice of geometric and thermal modeling parameters. Particular attention is paid to the stress-strain state of the rock under the influence of the gas jet heat flow, which is a key aspect in analyzing the efficiency of the fracture process. Various methods and parameters affecting the efficiency of heat exchange between the gas jet and the rock are also analyzed. An elastic half-space, which is a rock interacting with an external high-temperature medium, is considered. Heat exchange occurs according to the law of convection, and the maximum parameters of heat exchange from the jet to the rock are in the vicinity of the central point of its spreading at braking on the rock surface. The stress-strain state of the rock under the influence of the gas jet heat flow is investigated.

Key words: thermal tool, in-chamber pressure, fire-jet destruction, rocks.
