RUSSIAN OIL AND GAS SECTOR ON THE EVE OF THE WORLD ENERGY TRANSITION

M.I. Krutikhin, Cand. Sc. (History), Partner at RusEnergy Analytical and Consulting Agency

Abstract. The Russian oil and gas industry is in a difficult position, experiencing pressure from both the pandemic and the prospects of falling demand for fossil fuels in the face of the world economy transition to carbon-free development. Domestic companies, unlike their foreign counterparts, do not demonstrate readiness for a "green transition". The obvious degradation of quality of the reserves, the fiscal instability, the structural bias in favor of the public sector and Russia's participation in the OPEC+ deal provide no stimuli for the industry revival. The prospects of the gas sector are also doubtful in view of its poor hydrogen development potential.

Key words: oil and gas industry, decarbonization, oil, gas, natural gas well, oil well, hydrogen energy, energy transition.

Abstract. Demagnetization is the process of decreasing the magnetization of a ferromagnetic mass by applying an external magnetic field that alternately changes its sign. In many cases, it is required to reduce the magnetization of an object to the values of the Earth's magnetic field. The maximum demagnetizing field generated can be only a few mT (100–200 Gs), but due to the large size of the object (for example, the hull of a ship), a high electric current will need to be applied to create a sufficient magnetic field in the required area. Therefore, currently existing demagnetization systems are multi-ton coils of heavy copper electrical cables. The use of cables based on high-temperature superconductors (HTSC) in demagnetization systems allows significant weight savings compared to demagnetization systems based on copper coils. Our proposed design of the HTSC cable, which takes into account the "effect of the longitudinal magnetic field", makes it possible to further reduce the cost of the HTSC material. This paper presents the results of further optimization of such a cable for demagnetization systems, taking into account the real dependences of the critical current of second-generation HTSC tapes. In addition, the results of an experiment on demagnetizing a model steel object in a model of a system based on HTSC cables designed for demagnetizing small objects are presented.

Key words: HTSC cable, demagnetization, longitudinal magnetic field.

Abstract. The article deals with the practical aspects of the use of new type aluminum wires in the on-board DC harness of the spacecraft power supply system. The results of work on the analysis and adjustment of technological processes for the new type wire installation are presented. Optimal conditions for the production of electrical connections by soldering or mechanical crimping are determined. It is shown that the use of lighter wires to reduce the on-board DC harness weight while retaining the required level of reliability is technically feasible. The quality and reliability of the electrical connections are confirmed by a set of tests simulating the actual operating conditions of the spacecraft in the final orbit.

Key words: on-board DC harness, on-board wires, spacecraft, weight reduction, testing, crimped and soldered electrical connections, reliability.

MODERN SHIPBOARD CABLES

S.M. Piskunov, General Director of JSC “Expokabel”

Abstract. In recent times the shipbuilders and designers have been assigned the task of increasing the domestic market share in the global shipbuilding industry. However most of the projects under construction still use cable products that were developed more than 40 years ago, and no longer meet the present-day requirements of world shipbuilding. In order to solve this problem, JSC “SPO “Arktika” has developed and JSC “Expokabel” has introduced mass production of new generation shipboard cables that are direct competitors of the products manufactured by the leading world companies.

Key words: shipbuilding, modern technologies, operation, safety, shipboard electrical equipment, shipboard cables, fire-resistant cables, halogen-free cables, cable products, domestic shipbuilding, technical level, JSC “Expokabel”, modernization, production, customer orientation, efficiency.
