Nayara Energy Ltd., partially owned by Russia’s Rosneft with a nearly 50% stake, has delayed major maintenance at its 400,000 barrels-per-day Vadinar refinery in Gujarat from February to April 2026. The postponement stems from European contractors’ reluctance to engage due to EU sanctions imposed in July 2025 over Russia’s war in Ukraine, which targeted the refinery for allegedly funding the conflict. Previously reliant on suppliers like Germany’s Siemens AG and Denmark’s Topsoe A/S, Nayara now struggles to secure alternatives, heightening safety and operational risks since the last overhaul in November 2022. The sanctions have also halted the refinery’s petrochemical expansion plans after firms such as France’s Technip Energies and Japan’s Toyo Engineering withdrew. Rosneft deems the measures “unjustified and illegal,” while the facility continues processing Russian Urals crude.
