CASPIAN MARIA — Dredger · IMO 9195183

CASPIAN MARIA has not broadcast an AIS position for 188 days. The most recent broadcast placed it, on 2 May 2026, 09:15 UTC. It was sailing from ASTRAKHAN to ASTRAKHAN. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

CASPIAN MARIA broadcasts MMSI 273254640 and is registered as IMO 9195183. The MMSI is the radio identifier used by AIS; the IMO number stays with the ship for life and does not change with re-flagging or sale.

CASPIAN MARIA is classified as a dredger vessel registered under the RU flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full dredger fleet at /vessel-type/military-special and full RU flag list at /flag/ru.

AIS transponders broadcast position every 2 seconds when underway at high speed and up to every 3 minutes at anchor. The position you see refreshes whenever the ship is in range of a coastal AIS receiver or a satellite pass — typically seconds in coastal waters and minutes offshore.

As a dredger, CASPIAN MARIA sits in the same design class as the other dredgers listed in the Similar Vessels section of the vessel page, or in the full dredger directory at /vessel-type/military-special.
