Ce qu’est ce système
Ukraine's grain, oilseed and metals exports move by sea from the Odesa-area ports, with land routes through Europe a costly partial substitute. The route was blockaded in 2022, ran under a negotiated corridor until 2023, and has operated unilaterally since Ukrainian sea denial pushed the Russian fleet east.
The maritime half of Ukraine's export revenue and of Russia's southern sustainment; the system where sea denial, war-risk cover and corridor politics meet.

Le système
- Vue d’ensemble
- The network is two coasts and one sea. On the Ukrainian side the Odesa-area ports are the only outlet at scale for an export economy built on grain, oilseeds and metals, and the module's export record traces their history from the 2022 blockade through the negotiated corridor to the unilateral route that has operated since. On the Russian side the markers run from Novorossiysk and the Tuapse refinery and terminal to the occupied Azov ports, the Kerch crossing and the Crimean bases — the coastal end of the rear-area system and the object of Ukrainian sea denial.
- Current state · as of 2026-08
- As the export record last assessed it (August 2026): the unilateral route operating, Ukrainian sea denial holding the Russian fleet east, and land routes through Europe a partial substitute at a cost the module records on the corridor-revenue chain.
- Commodities and outputs
- Grain & oilseeds · Steel & iron ore
Nœuds
The published markers that carry this system value, by the module’s own priority. A note is the system record’s; a marker without one is a member by its own tag.

Russia's principal Black Sea port and crude outlet on this coast.
- OdesaPort
The principal Ukrainian port and the head of the export route.
- Pont et détroit de KertchGoulet d’étranglement des transports
The bridge and strait that join Crimea to the Russian rear.

Dependencies and constraints
Each marked documented (a published source states it) or assessed (Vigil infers it and says so). The two are never drawn the same way.
The Odesa-area ports. The only outlet at scale; land routes through Europe are a costly partial substitute and could not carry the volume.
