Attack on the Grushova Oil Depot
A drone assault targeted the Grushova transshipment oil depot, operated by Transneft subsidiary AK Transneft in Novorossiysk, sparking a fire at the facility. Grushova holds the title of the largest oil storage site in the Caucasus and serves as the terminal point for major pipeline networks. With a total tank capacity of roughly 1.2 million tons, the site features fifty reinforced concrete reservoirs of the ZBR-10,000 type. This attack marks the fourth strike on Novorossiysk’s oil infrastructure since the start of 2026.
The Grushova depot is part of the Sheskharis transshipment complex, operated by Chernomortransneft, itself a branch of Transneft. Novorossiysk, in turn, stands as Russia’s biggest Black Sea port. On May 23, 2026, drones hit both the Grushova and Sheskharis facilities. Imagery from Dnipro Osint confirmed the destruction of two storage tanks and damage to pipelines during this assault. It is also known that the tanker Chrysalis, part of Russia’s shadow fleet, was affected.
Impact of Strikes on Oil Infrastructure
This is far from the first blow to the region’s oil infrastructure. Sheskharis faced attacks in early March and again in April 2026. Following the April strikes, berths for Suezmax and Aframax tankers sat empty for several days. Overall, a series of spring 2026 strikes on terminals in Novorossiysk, Ust-Luga, and Primorsk cost Russia hundreds of thousands of barrels of oil.
The repeated assaults on Novorossiysk’s oil infrastructure highlight rising tensions in the region and potential repercussions for Russia’s energy security. The loss of substantial oil volumes could impact its economy and energy policy, given Novorossiysk’s strategic role as a key export hub for Russian petroleum products. These events also underscore evolving trends in modern warfare, where drone technology plays an increasingly prominent role in armed conflicts.
The ongoing assaults on oil facilities in Novorossiysk are part of a larger trend affecting Russia's energy landscape. For instance, a recent strike that disabled a significant portion of refining capacity underscores the vulnerabilities within the country's oil infrastructure. As tensions escalate, the implications for Russia's economic stability and energy strategy could be profound.
