TIGR — Tug · IMO 9527879

TIGR has not broadcast an AIS position for 50 days. The most recent broadcast placed it in the Sea of Japan, on 17 Sep 2026, 21:39 UTC. It was sailing from KOZMINO to KOZMINO. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

TIGR broadcasts MMSI 273343030 and is registered as IMO 9527879, with call sign UBAG7 . 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.

TIGR 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.

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.

TIGR is classed by RUSSIAN MARITIME REGISTER OF SHIPPING, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tug, TIGR sits in the same design class as the other tugs listed in the Similar Vessels section of the vessel page, or in the full tug directory at /vessel-type/tug-pilot-vessel. TIGR has a gross tonnage of 284 GT.
