NIKOLAI SEMENCHENKO — SAR · IMO 9912775

NIKOLAI SEMENCHENKO has not broadcast an AIS position for 133 days. The most recent broadcast placed it, on 27 Jun 2026, 15:45 UTC. It was sailing from ROSTOV-ON-DON to AZOV. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

NIKOLAI SEMENCHENKO broadcasts MMSI 273296170 and is registered as IMO 9912775. 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.

NIKOLAI SEMENCHENKO is classified as a sar vessel registered under the RU flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full sar 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.

As a sar, NIKOLAI SEMENCHENKO sits in the same design class as the other sars listed in the Similar Vessels section of the vessel page, or in the full sar directory at /vessel-type/tug-pilot-vessel.
