A second drone attack this week on Gazpromneft's Moscow refinery has damaged processing units and sparked multiple fires across the site, industry sources said. Moscow Mayor Sergei Sobyanin confirmed the region was targeted in a large-scale drone raid, with several drones falling on the refinery, which had previously been attacked on June 16.
Sources indicated that Thursday's attack damaged the Euro+ combined oil refining unit, commissioned in 2020 as part of the plant's modernization program. This unit includes a crude distillation section with a nominal capacity of around 140,000 barrels per day, representing 47% of the refinery's total capacity. Additionally, secondary units, inter-unit pipelines, and auxiliary equipment were damaged, and storage tanks containing oil products caught fire.
The refinery was already undertaking repairs following the June 16 attack, which damaged one of its two primary crude distillation units, CDU-6, with a normal capacity of approximately 160,000 bpd (53% of the plant's capacity). Sources had indicated plans to restart the Euro+ unit midweek and operate at about half capacity during the repairs to CDU-6. The refinery, located in southeastern Moscow, is a key supplier of fuel to the Russian capital.
