PORTIA — Cargo · IMO 9283980

PORTIA has not broadcast an AIS position for 155 days. The most recent broadcast placed it in the South China Sea, on 4 Jun 2026, 23:30 UTC. It was sailing from KARIANGAU to YANGJIANG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

PORTIA broadcasts MMSI 372377000 and is registered as IMO 9283980, with call sign H9MS . 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.

PORTIA is classified as a cargo vessel registered under the PA 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 PA flag list at /flag/pa.

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.

PORTIA is classed by AMERICAN BUREAU OF SHIPPING, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a cargo, PORTIA 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. PORTIA has a gross tonnage of 40,160 GT.
