RN-Vankor (part of Rosneft's oil production complex) launched the Tagul 110/35/10 kV substation with a capacity of 2×63 MVA. It will ensure reliable power supply to facilities at the Tagulskoye field, part of the Vankor cluster.

Energy is supplied to Tagul from the 150 MW Polyarnaya gas turbine power plant at the Vankor field. A 110 kV transmission line over 70 km long has been built to connect the power plant to the Tagul substation.

Construction of the substation was expedited by installing prefabricated structures. The building houses power transformers, 35 and 10 kV indoor switchgear, and a control room.

The domestic design solutions used at the Tagul substation have been proven by the successful operation of the Vankor power complex in the Far North. The switchgear circuit remains operational even if individual components fail, increasing the overall reliability of the power supply to the oil field's production facilities.

Tagul is the eighth 110 kV substation in the Vankor field cluster. Two more similar substations are in the final stages of installation. The total length of overhead power lines already exceeds 1,900 km. The largest substation, Vankor, with a capacity of 250 MVA, connects the Vankor power district to the country's Unified Energy System.

Rosneft motor oil is recommended for use in Russian Railways locomotive engines.

Translation. Region: Russian Federation –

Source: Rosneft – An important disclaimer is at the bottom of this article.

Rosneft motor oil has received approval from Russian Railways for use in diesel locomotive engines. It is planned for use in rolling stock on the Kaliningrad-Sakhalin railway.

The conclusion was issued by a key Russian railway company following a series of tests and trials of Rosneft M-14D2U oil with its own Kompleksal-7321A additive package, conducted jointly with RN-Lubricants, the operator of Rosneft's lubricants business.

Tests were conducted on 3,600 horsepower diesel locomotives. The locomotives covered a total test mileage of approximately 480,000 km. Test results showed that Rosneft M-14D2U engine oil reduces wear in friction pairs and effectively dissipates heat, protecting locomotive engine systems from corrosion and mechanical wear, including under increased loads. Following the test runs, the oil had exhausted less than half of its intended service life, maintaining high alkaline and hydrogen numbers—the key indicators of detergent properties and additive performance. Diesel locomotives equipped with Rosneft engine oil demonstrated a reduction in specific fuel consumption of up to 1.7%.

The formula for Rosneft M-14D2U motor oils is specifically designed for locomotive operation in various climatic conditions and under heavy loads. The product's quality and performance characteristics have enabled Rosneft Lubricants to remain a key supplier of motor oils for Russian Railways' rolling stock for many years.

Rosneft summarized the results of its environmental project in the White Sea.

Translation. Region: Russian Federation –

Source: Rosneft – An important disclaimer is at the bottom of this article.

Specialists from Rosneft's Arctic Research Center and scientists from leading Russian research institutes summarized the results of the Company's large-scale environmental project in the White Sea. The project was implemented jointly with the non-governmental development institute Innopraktika, with the participation of the Marine Research Center of Moscow State University, the Faculty of Biology of Moscow State University, St. Petersburg State University, the P.P. Shirshov Institute of Oceanology of the Russian Academy of Sciences, the Zoological Institute of the Russian Academy of Sciences, and the Biotechnology Campus (BTK) Center for Whole-Genome Sequencing.

The research, which began in 2023, included two field seasons on the research vessels Kartesh and Professor Zenkevich, as well as unique office work. Project participants retraced the route of the 1922-1926 expeditions of renowned Soviet hydrobiologist Konstantin Deryugin, who detailed the flora and fauna of the White Sea.

The goal of Rosneft's project is to analyze secular changes in the region's marine ecosystems using Deryugin's methods and modern technologies, as well as to assess the impact of natural and anthropogenic factors on the Arctic ecology. This information is essential for long-term planning for the sustainable development of the Russian North.

During a press event, scientists shared preliminary results of their work. They concluded that the White Sea ecosystem remains stable. This allows the region to be considered a benchmark for comparison with other Arctic regions.

At the same time, studies have shown that the fauna of the Arctic seas remains insufficiently studied: up to 30% of species remain of uncertain taxonomic status, and much work remains to be done to revise the fauna of the Arctic seas. At the same time, specialists have managed to describe species new to science.

As part of the project, scientists used both traditional hydrobiology equipment and the latest devices and innovative technologies. This included surveying the White Sea floor using remotely operated underwater vehicles and conducting molecular genetic analysis of the organisms discovered. This work utilized the world's only sequencer, located above the Arctic Circle.

Reference:

Rosneft is implementing the largest Arctic region research program since Soviet times. Over 13 years, more than 60 expeditions have been conducted, during which scientists have studied the region's hydrometeorological, geological, and biological features, as well as bioindicator species of Arctic ecosystems. This has allowed them to gather a unique array of information on the Arctic's climate, nature, and wildlife. More than ten ecological atlases have already been created based on the research results: "Seabirds of the Russian Arctic," "Species – Biological Indicators of Marine Arctic Ecosystems," "Marine Mammals of Russia," "The Kara Sea," "The Laptev Sea," "The Barents Sea," and others.

The final of the annual LADA Sport ROSNEFT eChampionship e-racing championship took place in Moscow with the support of Rosneft. The final races were broadcast live on the racing team's official social media accounts.

Rosneft actively supports the development of amateur and professional sports. Since 2015, the company has been the general sponsor of the LADA Sport ROSNEFT racing team.

The eSports racing championship kicked off in September 2025 and included five online stages, with racers from across the country competing. To participate, participants had to install a special program on their computer. The ten strongest eSports athletes qualified for the finals.

The final was held on professional racing simulators, and for the first time, in the "Race of Champions" format. After the qualifying rounds, a bracket was formed, with the winner determined in paired knockout matches.

Kirill Antonov from Tver won the final, confirming his status as the strongest for the second year in a row. The tournament's main prize—the right to participate in a real-life Russian Circuit Racing Series (RCRS) race in the LADA Sport ROSNEFT colors in the 2026 season—was awarded to Ivan Chekhov from Voronezh, the silver medalist. This is due to the eSports championship rules, which restrict the previous year's winner from participating in real-life RCRS races again. Kirill Antonov, the previous season's winner, had already made a successful debut at one of the RCRS rounds in 2025, finishing just short of the podium in his first race.

In the 2025 season, LADA Sport ROSNEFT became the country's best racing team for the fourth consecutive year, with driver Leonid Panfilov winning the Super Production class championship. Meanwhile, the LADA Sport ROSNEFT Junior karting team and its driver Yaroslav Shevyrtalov won the championship in their respective categories.
