Engineering Management of Energy Utilities for Sustainable Development

Abstract

The study proposes a model of engineering management of energy enterprises for sustainable development, which includes monitoring and evaluation of the technical condition of energy facilities, planning maintenance work based on the assessment results, and forecasting violations of normal operating conditions. Based on these data, the life cycle of energy equipment is managed, and the effectiveness of engineering decision-making is determined within the engineering management framework. The engineering management model is based on an integrated approach covering all equipment life cycle stages. On the example of pipeline systems of nuclear power plants, the article proposes to manage degradation processes and the sustainability of operations by reducing vibration load, which significantly impacts the efficiency, reliability, and safety of all power plant equipment. A damping vibration isolating support with an elastic rubber element is proposed, the advantage of which is the ability to adjust the stiffness of the support. Studies with the adjustment of the rigidity of the fasteners and the study of the amplitude-frequency characteristics of the pipeline section with additional damping supports showed a decrease in the maximum amplitudes of oscillations from 800 microns to 35 microns in section 1 and from 425 microns to 20 microns in section 2 and the effectiveness of their use for frequency restoration and reduction of oscillations.
