Gazprom Neft has completed the installation of major equipment for its “Sever (Northern)” digital electricity substation, which will provide standalone energy supplies to multi-well platforms (“cluster pads”) and residential amenities in the northern part of the field,* located 26 kilometres away from the asset’s main infrastructure facilities.
This substation is the first oil- and gas-industry facility to be built under a national project from the Ministry of Energy of the Russian Federation — “Commissioning Digital Electricity Stations and Substations at New and Reconstructed Energy Facilities”.** Its design and fitting-out was specially adapted — using innovative Russian-produced SF6 gas-insulation solutions — to ensure its effective operation under the extreme climatic conditions of the Arctic region.***
The 110/10Kw double-transformer “Sever” digital substation has the capacity to ensure uninterrupted electricity supply to a population of 10,00 people. Added to which, innovative “smart” control and diagnostics systems mean only a minimal number of personnel will be required for servicing the facility — something of major importance to remote field facilities. Signal transmission is handled digitally, ensuring maximum automation in measurement, control, safety and security services. The performance and reliability of all systems will be monitored by specialists at the Novoportovskoye field’s gas turbine plant (GTP) control room, remotely. The Sever digital substation comprises 95% Russian-produced equipment.
The Novoportovskoye field’s Sever digital substation is expected to be commissioned in late 2020.
“These days, an innovative approach to production problems is the most important factor in successfully solving them. And this is completely true of the energy sector. In creating high-tech generation and infrastructure facilities under the harsh conditions of the Arctic, our specialists are gaining unique experience. I have no doubt that these competencies are going to be in considerable demand in implementing new projects.”Andrey Komarov Director for Gas and Power Engineering, Gazprom Neft
“Using ‘smart’ standalone electrification systems is the key to implementing new projects in the Arctic, and to commissioning new fields. Building such a facility under the conditions of the Russian Far North now marks a unique landmark for the country. We are confident that our experience will open up new opportunities not just for developing the Novoportovskoye field, but also for other businesses operating in the Arctic Circle.”Alexey Ovechkin Director General, Gazpromneft-Yamal
* Developing the northern part of the Novoportovskoye field forms part of a promising project for Gazpromneft-Yamal in developing new reserves at this license block. The designing of key infrastructure facilities was completed in 2019, and full-scale drilling of cluster sites initiated. Investment in developing the northern section of the Novoportovskoye field currently stands at more than RUB86 billion. The Sever substation is currently being developed as the project’s key generation centre.
** The Sever digital substation is, currently, without peer. The project involves the most innovative solutions developed within the Russian energy “cluster”, all of which have been brought together as part of a unique digital “ecosystem”, adapted to operate under the conditions of the Russian Far North.
*** “SF6” refers to an integrated gas-insulated electricity distribution system used at power plants, urban substations, in supplying oilfield facilities (pipelines, drilling rigs), and in ship power-supply systems. Construction typically involves switching and measuring devices enclosed in an airtight metal case, and filled with sulphur hexafluoride (SF6) gas, significantly reducing devices’ overall dimensions, meaning they can be installed in block-modular constructions. As a result, this technology makes it possible — even at the design stage — to allow more compact dimensions for the substation per se, speeding up construction.
