Ukraine’s Navy Says It Hit Nefrit, Clouding CPC Terminal Repairs

Key Facts

1Ukraine’s Navy said an uncrewed surface vessel struck Nefrit in Sochi on September 3, 2026, but the extent of damage was not independently established.
2Nefrit was reportedly involved in planned CPC terminal repairs, and the timing of the work became uncertain after the attack.
3The terminal has 3 offshore moorings, with 2 normally used for loading and 1 held in reserve.
4The Tengiz–Novorossiysk pipeline runs 1,511 kilometers and carries more than 2/3 of Kazakhstan’s exported oil.

Ukraine’s Navy said one of its uncrewed surface vessels struck the Russian-flagged multipurpose support ship Nefrit in the port of Sochi on September 3, 2026. Reports reviewing the released material described an explosion and smoke near the vessel.

The extent of damage to Nefrit and its operating condition have not been independently established. Reports confirmed that the strike occurred near the ship based on the Ukrainian Navy’s announcement and published footage, without providing a reliable final damage assessment.

Bloomberg, in a report published by gCaptain, cited a person familiar with the matter as saying Nefrit was performing planned repairs at the Caspian Pipeline Consortium’s CPC export terminal near Novorossiysk. The source said the vessel was nearing completion of work at one mooring and was due to replace equipment at another, while CPC declined to comment on its contractors’ activities.

The established consequence so far is uncertainty surrounding the maintenance schedule. The source said the timing of repairs had become unclear, but available reports did not confirm any change in crude loading or pipeline flows.

CPC’s marine terminal has 3 offshore single-point moorings. The report said 2 are normally used for loading and 1 is held in reserve, so the operational effect of any delay depends on the mooring involved, the duration of the support vessel’s unavailability and access to suitable alternatives.

CPC said its modernization program includes replacing 2 moorings commissioned in 2001 during 2026, after the required anchors were installed in 2025. The consortium also said preparations to replace SPM-2 were underway in May 2026 after it was damaged in November 2025.

The Tengiz–Novorossiysk pipeline runs 1,511 kilometers and carries more than 2/3 of Kazakhstan’s exported oil, according to CPC. On July 19, 2026, the consortium stopped loading after 2 tankers were targeted, then suspended loading again on July 30, 2026, after a tanker was attacked while operating at SPM-3.

The supply risk will become clearer after a reliable damage assessment for Nefrit, an updated repair timetable and confirmation of the status of the moorings and loading operations. Until that information is available, the scale of any effect on exports or shipping and insurance costs remains unknown.
