TROMSO — Tanker · IMO 9435791

TROMSO has not broadcast an AIS position for 213 days. The most recent broadcast placed it in the South China Sea, on 9 Apr 2026, 10:21 UTC. It was sailing from DALIAN to SINGAPORE ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

TROMSO broadcasts MMSI 311013300 and is registered as IMO 9435791, with call sign C6XL5 . 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.

TROMSO is classified as a tanker vessel registered under the BS 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 BS flag list at /flag/bs.

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.

TROMSO is classed by AMERICAN BUREAU OF SHIPPING, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a tanker, TROMSO 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. TROMSO has a gross tonnage of 8,247 GT.
