A Ukrainian naval drone struck the vessel Nefrit near Sochi as it was completing repairs on a Caspian Pipeline Consortium (CPC) terminal berth. The attack threatens planned maintenance and raises uncertainty over Kazakh oil exports through the CPC, which handles more than 80% of Kazakhstan's crude shipments.

Key Facts

The Ukrainian Navy said a sea drone struck the vessel Nefrit near Sochi, recording a powerful explosion and smoke near the ship.
The Nefrit had nearly completed work on one CPC berth and was scheduled to begin replacing equipment on another, according to Bloomberg sources.
The CPC terminal has three offshore berths, with Berth No. 2 damaged in November 2025 and replaced earlier this year.
Kazakhstan's Energy Ministry said in late August it expected all three berths to be operational in September.
Kazakhstan revised its 2026 oil production forecast from 98 million to 96 million tonnes after July attacks on CPC infrastructure halted loadings.

The Attack

The Ukrainian Navy said a sea drone attacked the vessel Nefrit in the Sochi area, with footage showing a powerful explosion and smoke near the ship. According to the Ukrainian Navy, the Nefrit serviced oil and gas infrastructure, transported cargo and personnel, and performed underwater technical work, thereby supporting Russia's economy and financing the war against Ukraine. The CPC press service declined to comment on the work of contractors at the marine terminal.

Impact on CPC Operations

The Nefrit had practically completed work on one berth and was due to begin replacing equipment on another, according to Bloomberg sources. The attack threatens to disrupt planned repairs and increases uncertainty around further oil loading operations through the CPC. The CPC terminal has three offshore berths, with loading normally carried out from two while the third serves as a reserve. Berth No. 2 was damaged in November 2025 and replaced earlier this year, and Kazakhstan's Energy Ministry said in late August it expected all three berths to be operational in September.

Kazakhstan's Exposure

More than 80% of Kazakhstan's oil exports pass through the CPC. A series of attacks on CPC infrastructure in July led to a suspension of loadings and a reduction in production. Kazakhstan revised its 2026 oil production forecast from 98 million to 96 million tonnes. Oil and gas analyst Nurlan Zhumagulov said the strike on the Nefrit is an indirect blow to CPC infrastructure because there is no similar support vessel with a helicopter deck in the Black Sea. The Nefrit is actively used for operations supporting CPC single point moorings, including replacement, flushing, and repair of floating and underwater loading hoses, Zhumagulov said.
