SERIFOS — Tanker · IMO 9371256

SERIFOS has not broadcast an AIS position for 13 days. The most recent broadcast placed it in the Mediterranean Sea, on 27 Oct 2026, 16:12 UTC. It was sailing from ALGECIRAS to GIBRALTAR WEST ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SERIFOS broadcasts MMSI 210555000 and is registered as IMO 9371256, with call sign 5BDM6 . 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.

SERIFOS is classified as a tanker vessel registered under the CY flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tanker fleet at /vessel-type/tanker and full CY flag list at /flag/cy.

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.

SERIFOS is classed by AMERICAN BUREAU OF SHIPPING, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, SERIFOS sits in the same design class as the other tankers listed in the Similar Vessels section of the vessel page, or in the full tanker directory at /vessel-type/tanker. SERIFOS has a gross tonnage of 3,220 GT.
