Russia’s Novorossiysk port complex on the Black Sea, a hub that handles roughly one-fifth of the country’s crude exports, has become a key target in Ukraine’s campaign to disrupt Moscow’s energy revenues. In late November 2025, a Ukrainian sea-drone strike disabled one of the Caspian Pipeline Consortium’s main offshore loading buoys, forcing a temporary halt to shipments and underscoring how even a 2% disruption in global oil supply can jolt markets.
The attack sharpened questions for governments, energy companies, and traders: how resilient is Russia’s export infrastructure, and how long can a vital artery for both Russian and Kazakh crude operate under sustained threat?
Strategic Role of the Caspian Pipeline Consortium
Formed in 1992, the Caspian Pipeline Consortium (CPC) is an unusual joint venture linking Russia, Kazakhstan, and major Western energy firms including Chevron, ExxonMobil, Shell, and Eni. Its pipeline runs more than 1,500 kilometers from Kazakhstan’s giant Tengiz, Kashagan, and Karachaganak fields to an offshore loading terminal near Novorossiysk on Russia’s southern coast.
CPC is central to the global supply balance. In 2024, it shipped around 63 million tonnes of crude, much of it Kazakh oil blended and exported via Russia’s Black Sea coast. For Kazakhstan, which accounts for roughly 2% of world output, CPC carries around 80% of its crude exports. This dependency makes the terminal’s vulnerability to attack a critical issue not just for Moscow, but for Astana and the Western partners invested in the project.
Escalating Strikes and the November 29 Attack
Drone attacks on Novorossiysk and nearby infrastructure intensified through 2025. In September, Ukrainian drones struck CPC’s city office in Novorossiysk. By mid-November, additional attacks damaged port facilities, oil depots, and container terminals. On November 25, a strike hit CPC’s administrative building at the marine terminal, signaling that offshore operations were at increasing risk.
Four days later, the campaign reached a new phase. At 04:06 Moscow time on November 29, Ukrainian uncrewed surface vessels, or sea drones, hit the CPC marine terminal’s SPM-2 single-point mooring buoy, one of three offshore units used to load tankers. The consortium reported serious damage to SPM-2 that rendered it inoperable. Cargo operations stopped immediately, tankers were ordered to leave CPC waters, and the system’s emergency protection mechanism shut off the relevant pipelines.
Analysts estimated that the stoppage put roughly 2.2 million barrels per day of crude at risk, including about 46.6 million tonnes per year of foreign shippers’ throughput. For consortium members, particularly Chevron and ExxonMobil, which operate major fields in Kazakhstan under production-sharing agreements, the disruption represented a direct hit to export capacity and revenue.
Kazakhstan, Western Firms, and a Shrinking Export Map
The strike left Kazakhstan in a difficult position. With SPM-2 offline, the country temporarily lost access to around 55 million tonnes of annual export capacity. Kazakh officials protested publicly on November 30, describing the CPC terminal as an exclusively civilian installation and urging Ukraine to stop targeting it. Yet Kazakhstan’s main alternative pipelines also cross Russian territory, limiting its ability to diversify routes quickly without major economic costs.
Western energy majors also faced unexpected exposure. Collectively holding more than 30% of CPC, Chevron, ExxonMobil, Shell, and Eni profit from each barrel shipped through Novorossiysk. The halt in loadings, though partially eased within days, underscored the operational and financial risk of maintaining assets in a war-adjacent corridor. None of the firms offered detailed public assessments of the damage, but market participants quickly adjusted expectations for near-term Kazakh and Russian supplies.
The pressure on Novorossiysk coincided with an apparent decline in exports through Primorsk, Russia’s largest crude terminal on the Baltic Sea, where shipments reportedly fell about 73% in recent weeks, to roughly 43,000 tonnes per day. Together, the setbacks at the Black Sea and Baltic outlets suggested that Ukraine was targeting Russia’s export network across multiple fronts, forcing Moscow to consider more limited and costly alternatives through the Arctic or Caspian.
Repairs, Environmental Risks, and Evolving Drone Tactics
CPC has not disclosed a timetable for restoring SPM-2, but damage from explosives to an offshore mooring can take weeks or months to fix, especially if underwater structures or manifolds are affected. Repair schedules are further complicated by sanctions, security concerns, and potential shortages of specialized parts.
By December 1, the consortium announced it had resumed limited exports via SPM-1, the buoy that escaped the November 29 strike. That restart allowed some shipments to flow but left the terminal operating with minimal redundancy. Any successful strike on SPM-1 could force a full shutdown, magnifying the leverage of relatively low-cost sea drones over a complex, capital-intensive facility.
The November 29 attack also highlighted environmental stakes. CPC’s automated shutdown system isolated pipelines within fractions of a second, preventing crude from spilling into the Black Sea. Emergency response teams were deployed, and seawater monitoring began as a precaution. The incident illustrated how future strikes on offshore terminals could trigger serious ecological damage if safety systems fail or are overwhelmed.
Ukraine’s sea-drone capabilities have advanced rapidly. Upgraded platforms unveiled in 2025 feature longer range, improved autonomy, and better survivability against Russian defenses. Operating close to the water’s surface, these vessels are harder to detect by radar and are less vulnerable to traditional air-defense systems. Military analysts argue that Russia lacks the resources to provide full protection for all three CPC moorings and other key export points, creating a persistent asymmetry between inexpensive unmanned systems and costly defenses.
For global energy markets, the Novorossiysk strikes reinforce a broader shift. Supply risks now stem not only from state policy or cartel decisions but from the precision of low-profile attacks on critical infrastructure. If Ukraine maintains the ability to keep a significant share of Russian and Kazakh exports intermittently offline, other producers could gain market share while investors reassess the long-term viability of mixed-ownership projects in contested regions. Whether Western partners stay in CPC or eventually retreat will influence whether Novorossiysk remains a linchpin of Eurasian crude flows or becomes a more isolated Russian facility that the market learns to bypass.
