Ukrainian Sea Drone Destroys Russian Ship Vital To CPC Oil Repairs

Tit-for-tat attacks on commercial vessels in the Black Sea as well as Sea of Azov have been raging all summer, but Ukrainian forces are now strategically going after smaller ships which yet play an outsized role in repair and logistics related to damaged Russian and central Asian oil infrastructure.

"Ukraine attacked a small service ship involved in planned repair works at the key CPC oil terminal in the Black Sea, a person with knowledge of the matter said," Bloomberg reports Thursday.

"The Nefrit has almost completed works at one mooring and was set to start replacing some equipment at another, the person said on condition of anonymity as the information is not public," the report continues.

Crucially, "The attack puts the scheduled works in limbo and raises uncertainty over CPC’s future crude-loading operations, the person said."

Various videos which have emerged showing that the multipurpose vessel was hit by a naval drone as it was docked in the faraway port of Sochi.

Local media has also said that "earlier, reports claimed that a series of explosions occurred near the port during the attack. A Russian Pantsir SPAAGM system was also spotted near one of the strike locations."

Starting in July, all hell broke loose when, in tandem with strikes on Russian shipping in the Sea of Azov, Ukrainian attacks on the Novorossiysk CPC terminal forced Kazakhstan to repeatedly shut down the pipeline, causing shipping and insurance rates to more than double. CPC's loading of tankers has plunged. 

Hence it's clear that Ukraine is seeking to keep Russia's Black Sea oil operations crippled, also as it continues to try and hit refineries and loading terminals by air via long-range drones.

Needless to say, the now destroyed Nefrit vessel was vital to rapid repair operations connected to Kazakhstan's crude exports at offshore rigs, and so these efforts will inevitably be significantly slower.

The Trump administration's attention to oil supplies coming from Kazakhstan must be placed in the context of the other war and hotspot sill raging: the six-month old war on Iran.

The administration has been pulling out all the stops to moderate fuel prices that have surged with Iran's lengthy de facto closure of the Strait of Hormuz. Washington needs alternatives to Gulf oil to keep flowing.

Russia has been waging its own war on Ukrainian shipping and its key ports, particularly the vital national port at Odesa. As part of the latest, Russia has on Thursday hit two vessels with cargo bound for Ukraine in the Black Sea, Interfax freshly reports.
