More than 40 larger commercial ships, with a capacity above 20,000 dwt are trapped in Ukrainian ports. The vast majority of them are bulkers.

Vessel tracking data available on the Signal Ocean and MarineTraffic data platforms show most vessels are in Black Sea ports still under Ukrainian control — Odessa, Chornomorsk, Mykolaiv, Yuzhnyy and Olvia.

Russian forces are understood to have captured Kherson, a big city with a relatively minor port by the Black Sea.
