Oil shipments through the CPC have been halted again.
A drone attacked the NELSA tanker while it was loading crude at the Caspian Pipeline Consortium’s marine terminal. The vessel was stationed at Single Point Mooring 1, or SPM-1, DKNews.kz reports.
For Kazakhstan, this is not an isolated maritime incident. More than two-thirds of the country’s exported oil is transported through the CPC system.
What Happened to the NELSA Tanker
The attack occurred on July 20, 2026. The drone struck the starboard side of the vessel’s stern, between the superstructure and the engine and boiler room.
The impact caused a fire on the deck and in several compartments. The tanker’s crew and CPC emergency response teams fought the blaze for several hours.
“The strike hit the starboard side of the vessel’s stern, between the superstructure and the engine and boiler room. As a result, a fire broke out on the deck and in several compartments of the tanker.”
The vessel remained afloat. No oil spill occurred, and the crude stored in the cargo tanks did not catch fire.
Twenty-two members of the international crew were evacuated aboard CPC tugboats. The captain and chief officer remained on board.
According to Kazakhstan’s Ministry of Energy, no injuries were reported.
“The vessel’s technical condition and the consequences of the incident are currently being assessed. The Ministry of Energy of the Republic of Kazakhstan remains in constant contact with the Caspian Pipeline Consortium,” the ministry said.
Oil Loading Resumed — Then Stopped Again
A day earlier, on July 19, drones attacked the ASIA and NISSOS IOS tankers while they were loading oil produced in Kazakhstan. Fires broke out aboard the vessels, but their crews quickly brought them under control.
Loading operations resumed later that evening. They were suspended again on July 20 following the attack on the NELSA.
Kazakhstan’s main oil export route shifted from normal operations to emergency mode twice in less than 24 hours. The duration of the latest suspension will depend on assessments of the tanker, the loading equipment and security conditions in the surrounding waters.
The Ministry of Energy has not yet announced when oil shipments will fully resume.
Why This Matters for Kazakhstan
The CPC connects oil fields in western Kazakhstan with a marine terminal near Novorossiysk. The Tengiz–Novorossiysk pipeline stretches for 1,511 kilometres.
Most of Kazakhstan’s exported crude, including oil from the Tengiz, Kashagan and Karachaganak fields, travels along this route. A prolonged shutdown could disrupt shipping schedules and put pressure on producers.
A brief suspension does not automatically mean production at the oil fields will stop. But if the export route remains closed for an extended period, companies may have to find additional storage, revise production plans or reduce output.
The disruption could also generate additional costs. Shipowners, insurers and exporters may begin pricing higher security risks into transportation rates.
Kazakhstan Condemns Attacks on Civilian Vessels
Kazakhstan’s Ministry of Foreign Affairs described the attacks on the tankers as a threat to the country’s economic interests and the stability of international trade.
“An unacceptable infringement on the economic interests of the Republic of Kazakhstan, as well as actions aimed at destabilising legitimate international trade, global energy markets and the security of global transport and logistics supply chains,” the ministry said.
The Ministry of Energy said the use of force against international energy infrastructure creates risks for global energy security.
Kazakhstan’s official statements did not identify who operated the drones. It would therefore be inappropriate to attribute responsibility without officially presented evidence.
An Environmental Disaster Was Avoided
The tanker was struck while stationed next to an offshore oil-loading facility. The fire broke out close to the engine and boiler room and the cargo area.
No oil entered the sea. However, the location and nature of the damage reveal the scale of the potential environmental threat to the Black Sea.
A major accident involving a loaded tanker could have resulted not only in the loss of the vessel but also in widespread marine pollution. The crew, emergency response teams and terminal infrastructure would also have faced serious danger.
The CPC marine terminal has three single point moorings. They allow tankers to load oil at a considerable distance from the coast.
The system’s uninterrupted operation, however, depends directly on the safety of vessels and the surrounding waters.
An International Project Is Now in the Risk Zone
The CPC is not solely a Kazakh-Russian route. Some of the world’s largest oil and gas companies participate in the project.
Its shareholders include Kazakhstan through KazMunayGas and Kazakhstan Pipeline Ventures, as well as Russia, Chevron, ExxonMobil, Lukoil, Shell and Eni. Any shutdown of the terminal therefore affects the interests of several countries and multinational corporations.
The CPC called on the project’s participating countries to take practical measures to protect the export infrastructure. The issue concerns the safety of civilian shipping, international crews and oil supplies from Kazakhstan’s fields.
For Astana, the challenge goes beyond inspecting one tanker and restarting loading operations. The repeated attacks have exposed the vulnerability of a route that underpins Kazakhstan’s export revenue, oil production and budget income.
