Ukraine attacks service ship at CPC oil terminal in Black Sea

Ukraine hit a small service vessel at the Caspian Pipeline Consortium oil terminal in the Black Sea, continuing a campaign of drone strikes against energy infrastructure that has rattled global oil markets and infuriated Kazakhstan, a country that had nothing to do with the war but now finds its economic lifeline under fire.

The CPC terminal, located near the Russian port city of Novorossiysk, handles the vast majority of Kazakhstan’s crude exports. Disrupting it, even briefly, sends ripples through global energy supply chains.

What the CPC terminal actually is, and why it matters

The Caspian Pipeline Consortium operates a roughly 1,500-kilometer pipeline stretching from Kazakhstan’s Tengiz oil field to the Black Sea coast. The terminal at its endpoint is where that crude gets loaded onto tankers and shipped to world markets.

Kazakhstan routes approximately 80% of its total crude exports through this single corridor. That volume represents more than 1% of global oil supply.

The terminal has become a recurring target since late 2025, when Ukraine began escalating drone operations against Russian energy infrastructure in the Black Sea region. Ukraine has framed the strikes as legitimate military tactics aimed at degrading Russia’s ability to fund its invasion.

A pattern of escalating strikes

In January 2026, drone strikes impacted the tanker Nissos Sifnos at the terminal, sparking fires and forcing an immediate halt to loading operations. A subsequent attack hit the vessel Marathi, producing similar disruptions.

Russia has reported direct damage to mooring structures and loading facilities across multiple incidents. Each time, operations were suspended for inspections before eventually resuming.

No casualties have been reported in most of these incidents, and Ukraine has denied causing any environmental disasters such as oil spills. The damage has been primarily economic and operational.

Kazakhstan caught in the crossfire

For Astana, the situation is deeply frustrating. Kazakhstan has publicly condemned the attacks, emphasizing that they threaten civilian vessels and undermine the economic stability of a country that depends on uninterrupted oil exports for a huge share of its national revenue.

When 80% of your crude exports flow through a single pipeline to a single terminal in a war zone, you have a diversification problem. Kazakh officials have called for exploring alternative export routes, but building new pipeline infrastructure takes years and billions of dollars.

The repeated disruptions have introduced volatility into Kazakhstan’s oil output and revenue projections. Even when physical damage is minimal and operations resume quickly, insurers charge more to cover tankers loading at a terminal that gets hit by drones every few weeks, and shipping companies factor risk premiums into their rates.
