Ukrainian drone and maritime strikes are severely disrupting Russia’s Black Sea export logistics, especially grain through Novorossiysk, and are challenging Russia’s ability to export via the Azov-Black Sea basin.

Analysts from SovEcon, Argus Media, CREA and data references from Reuters and Bloomberg are cited to assess terminal loadings and the broader impact.

August countermeasures include vessels like the Sierra Leone-flagged Caruzo with water tanks tied around its stern and the Russian-flagged Khrizopraz with tyres over its hull as they traversed the Bosphorus.

Re-routing shipments is not a full solution due to limited capacity and higher costs, underscoring the fragility of regional export routes.

Several ships, including the Great Ocean, arrived at the Bosphorus heavily damaged, highlighting ongoing risks to maritime traffic.

Analysts warn that ongoing disruptions threaten export revenues and may push volumes toward alternative routes like Baltic ports Primorsk and Ust-Luga, though those options bring higher costs and longer transit times.

Turkey has sought to mediate grain transit through the Black Sea, with discussions between Erdogan and Foreign Minister Fidan on restoring safe passage, while Russia opposes renewing the Black Sea grain deal.

While improvised defenses such as cope cages, water tanks, and tyres offer some protection against smaller drones, they may be ineffective against larger, rapid, remote-controlled drones or payload-equipped aircraft.

The frequency of attacks on ships and port infrastructure delivering oil and grain exports has increased since July, raising concerns about further escalation.

Oil exports are also affected, with the Sheskharis terminal reporting temporary load stoppages and ongoing disruptions impacting Black Sea corridor volumes.

Broader market implications include potential downward pressure on grain prices domestically and concern over Russia’s near-term ability to meet international demand.

There is growing use of improvised anti-drone defenses on Black Sea–transiting ships, including nets, water tanks, and tyres to mitigate drone threats amid intensified strikes.
