Black Sea network

The ports, approaches and coastal infrastructure through which Ukraine's grain, oilseed and metals exports move by sea — and the Russian coast the same water serves.

Context, not targeting. A system record names published markers and published operators and states dependencies at the level a published institution does. It carries no facility-level capacity, vulnerability, protection or repair detail; the schema has no field for any of it.

What this system is

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.

The system

Overview
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.

Nodes

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.

Routes and operators

Supply systems running through it

  • Black Sea export systemGeneral trade · 6 nodes · 3 documented disruptions · named by the recordThe route that carries most of what Ukraine sells, closed by blockade and reopened without an agreement.
  • Russian rear-area sustainmentMilitary sustainment · 8 nodes · 3 documented disruptions · joined by its nodesAn army that runs on rail, and a war fought at the range a railhead can support.
  • Crude refining and domestic fuel supplyFuel imports · 10 nodes · 2 documented disruptions · joined by its nodesThe tier between an oil producer and a working petrol station — and the one place in Russia's energy system where a shortage is possible at all.

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.

Transmission chains through this system

Each step carries its own basis grade — Confirmed, Plausible exposure, Unconfirmed scenario — and a chain can only weaken from left to right.
