RATIBOR — Tug · IMO 9556521

RATIBOR has not broadcast an AIS position for 200 days. The most recent broadcast placed it in the Barents Sea, on 20 Mar 2026, 13:37 UTC. It was sailing from MURMANSK to MURMANSK. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

RATIBOR broadcasts MMSI 273343630 and is registered as IMO 9556521, with call sign UBFG5. 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.

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