ST1 — Tanker · IMO 9256999

ST1 has not broadcast an AIS position for 17 days. The most recent broadcast placed it in the Persian Gulf, on 22 Oct 2026, 20:29 UTC. It was sailing from AL BASRAH ANCH to DUBAI ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

ST1 broadcasts MMSI 538011222 and is registered as IMO 9256999, with call sign V7A6819. 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.

ST1 is classified as a tanker vessel registered under the MH 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 MH flag list at /flag/mh.

MarineRadar shows the latest AIS broadcast from ST1 above, with current position, course, speed, and navigation status. Tap "View on map" to centre the live tracker on the vessel and watch its movement update in real time. The same data is available offline-friendly in the iOS and Android apps.

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.

ST1 is classed by DET NORSKE VERITAS, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, ST1 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. ST1 has a gross tonnage of 159,530 GT.
