The operation and development of the oil and gas fields requires the solution of issues related to the optimization of generation and consumption of electricity, the use of the most modern energy-efficient technologies, which allow to ensure a continuous power supply of offshore hydraulic structures (OHS). A specific feature of the development of offshore oil fields is the difficulty of ensuring significant ‘flexibility’ of power supply systems for the entire OHS fleet, allowing to quickly meet the needs and changes in the technological scheme of development, construction, methods of field exploitation, while having the capacity and reserves corresponding to the current state.

In order to ensure continuous production, Vietsovpetro JV has created a unique, energy-efficient, autonomous power supply system for hydraulic structures - the United Power Grid (UPG). UPG energy efficiency was achieved through the implementation of utilization system for associated gas, treated as fuel for the energy hub turbine generators. The article describes the main elements of UPG, incorporated limiting systems for short-circuit currents and power factor compensation. The introduction of the UPG made it possible to increase the utilization rate of associated gas, reduce operating costs, and improve the quality and reliability of electricity supply, while the Digital Twin for UPG allowed significantly reduce the time, optimize operating and capital costs during an upgrade and development of the energy system. The article covers the stages of UPG creation, its current state and describes the generating-consuming balance for electricity at the steady run. The paper presents the actual data on production costs reduction and provides for the system development perspective – power supply of mobile offshore structures, complete implementation of operational dispatching management system and integration of the advanced M&R system for energy equipment based on actual condition, resulting in significant reduction of losses in production costs.
