SIVUCH — Tug · IMO 9157820

SIVUCH has not broadcast an AIS position for 6 days. The most recent broadcast placed it, on 1 Nov 2026, 12:37 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.

SIVUCH broadcasts MMSI 273418870 and is registered as IMO 9157820, with call sign UBWQ2. 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.

SIVUCH 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.
