Aim. Today, dynamically-loaded foundations of process equipment often prove to be oversized with significantly overestimated values of stiffness, mass and material consumption. Therefore, reducing the costs and time of construction of gas pipeline facilities, especially on permafrost, is of relevance to PJSC Gazprom. One of the primary ways of solving this problem is installing gas pumping equipment on light vented support structures. The disadvantage of such structures is the low vibration rigidity. A method [1] is proposed for improving the vibration rigidity of a foundation subjected to vibration load. The simulation aims to improve the dependability of light vented foundations by studying vibration displacements of foundations with attached reinforced concrete panels depending on the thermal state of frost soils, parameters of the attached panels and connectors. Methods. Vibration displacements of a foundation with an attached device were identified using the finite element method and the improved computational model of the foundation – GCU – soil system. Results. Computational experiments identified the vibration displacements of the foundation in the cold and warm seasons for the following cases of reinforced concrete plates attached to the foundation: symmetrical and non-symmetrical; at different distances; through connectors with different stiffness parameters; with additional weights; frozen to the ground. Conclusions were made based on the results of simulation of vibration displacements of foundations with an attached device in cold and warm seasons. Conclusion. The presented results of computational experiments aimed at improving the vibration rigidity of light foundations by using method [1] show sufficiently good indicators of reduced vibration displacements of the foundation. Thus, in the case of symmetrical connection of four reinforced concrete panels in summer, the reduction of vibration displacements is 42.4%, while increased stiffness of the connectors, attachment of additional weights and freezing of reinforced concrete panels into the ground will allow reducing the vibration displacements of the foundation up to 2.5 times. However, it should be noted, that applying the findings in the process of development of project documentation and construction of foundations requires R&D activities involving verification and comparison of the obtained results of numerical simulation with a natural experiment.

In the Kaliningrad region there are about 70 % of all polder lands in Russia. On these lands with high potential fertility, it is advisable to intensive agriculture. The area for the average moisture year is an area with excessive moisture, which indicates the need to maintain the rate of drainage on agricultural land. Many different factors play a role in ensuring the drainage rate, one of which is pumping stations and pumping equipment installed on them. An important parameter in the use of pump-power equipment is energy consumption, since in this industry it is a considerable expense item. Improving the energy efficiency of pumping stations on polders is a pressing issue today. At the majority of polder pumping stations, domestic power pumping equipment is installed with excess power and head of 4–8 meters, and a new one is selected based on the maximum possible head in a given place. In the Kaliningrad region, the energy efficiency of polder pumping equipment has never been analyzed. In this paper, a statistical processing of the geodesic pressure of water at the polder pumping stations of the Slavsk region for 2000–2002 was carried out. On the basis of these data and data on the hydraulic characteristics of pressure pipelines, the calculated water pressures were determined for the rational selection of pumping equipment. The calculation of the economic efficiency of pumps with optimal power compared with pumps of excess capacity. The results of the study can serve as a justification for the transition to the pumping equipment with less power and pressure, which will lead to a decrease in the cost of money for electricity.

The challenges of increasing the energy efficiency of the economy as a whole and of certain production sectors in particular are a priority both in our country and abroad. As part of the energy policy of the Russian Federation to reduce the specific energy intensity of enterprises in the oil transportation system, Transneft PJSC developed and implements the energy saving and energy efficiency improvement Program. The application of energy-saving technologies allowed the company to significantly reduce operating costs and emissions of harmful substances. At the same time, further reduction of energy costs is complicated for objective reasons. The objective of this article is to present additional methods to improve the energy efficiency of oil transportation by the example of the organizational structure of Transneft. Possibilities to reduce energy costs in the organization of the operating services, planning and execution of work to eliminate defects and preparatory work for the scheduled shutdown of the pipeline, the use of pumping equipment, including pumps with variable speed drive, the use of various pipelines layouts, changing the volume of oil entering the pipeline system and increase its viscosity.
