Kazakhstan has condemned drone attacks on three tankers near the Caspian Pipeline Consortium’s Black Sea terminal on July 17 and 19. The two latest vessels were hit while loading Kazakh oil.

The Liberia-flagged ASIA and NISSOS IOS were attacked at single-point moorings SPM-1 and SPM-3 near Novorossiysk. ASIA was loading Tengizchevroil crude. The Marshall Islands-flagged NISSOS IOS was loading oil from Kashagan B.V. and Maten.

A fire broke out on ASIA and was extinguished with CPC emergency support. No injuries were reported among the crews, CPC staff, or contractors. Both tankers remained afloat, no oil entered the sea, and the moorings were not damaged. Loading was suspended while specialists assessed the damage.

“Kazakhstan demands an immediate halt to these attacks,” the Foreign Ministry said. It described the strikes as an unacceptable infringement on Kazakhstan’s economic interests and a deliberate attempt to disrupt lawful international trade.

The ministry said an agreed system for sharing information on civilian vessels entering the Black Sea to load CPC oil had been deliberately ignored. It said the failure endangered crews, called for practical security measures, and reserved Kazakhstan’s right to seek full compensation under international law.

Ukraine’s General Staff said its forces struck two tankers in the Black Sea overnight on July 19. It said the vessels were used to transport Russian oil, petroleum products, and fuel for Russia’s armed forces. The post did not name the tankers. CPC said both ships at its terminal were loading oil produced in Kazakhstan and did not publicly identify the attacker.

The July 19 incident followed an attack on Nordic Zenith on July 17. The Suezmax tanker was empty and approaching the terminal when two drones hit it. The crew extinguished a fire. Nearby CPC vessels evacuated 13 crew members, while nine stayed aboard. CPC removed the ship from its loading schedule and said it was unfit to berth. Sources told Reuters that ExxonMobil had chartered the vessel.

CPC called the July 19 attack the fifth act of direct aggression against a civilian facility protected by international law. “An attack on the company’s facility and civilian vessels at the CPC Marine Terminal is also an attack on the interests of the consortium’s member countries,” it said. The consortium has Kazakh and Russian shareholders, alongside U.S. and European energy companies.

The 1,510-kilometre pipeline links western Kazakhstan to a terminal near Novorossiysk. It carries oil from Tengiz, Kashagan, and Karachaganak. The route handles about 80% of Kazakhstan’s oil exports. CPC shipped about 70.5 million tonnes in 2025, with foreign producers accounting for more than 75% of the volume.

The latest strikes extend a series of attacks around the terminal. In January, drones hit Delta Harmony and Matilda while they waited to load Kazakh crude. A November 2025 strike damaged SPM-2 and reduced loading capacity for weeks.

After the November disruption, Kazakhstan rerouted about 300,000 tonnes in December through the KazTransOil system. The routes included Atyrau-Samara, China, and the Baku-Tbilisi-Ceyhan corridor. That was about 0.4% of CPC’s 2025 throughput.

The duration of the latest suspension remains unclear. Kazakhstan’s Energy Ministry said it would issue further information after the assessment. It had not announced when loadings would resume.
