GEMMA — Cargo · IMO 9509097

GEMMA has not broadcast an AIS position for 92 days. The most recent broadcast placed it in the Persian Gulf, on 6 Aug 2026, 09:01 UTC. It was sailing from ASALUYEH to SOHAR. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

GEMMA broadcasts MMSI 511873000 and is registered as IMO 9509097, with call sign T8A3035. 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.

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

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.

GEMMA is classed by AMERICAN BUREAU OF SHIPPING, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a cargo, GEMMA sits in the same design class as the other cargos listed in the Similar Vessels section of the vessel page, or in the full cargo directory at /vessel-type/cargo. GEMMA has a gross tonnage of 2,728 GT.
