OBSERVATOR — Cargo · IMO 9553244

OBSERVATOR has not broadcast an AIS position for 5 days. The most recent broadcast placed it in the South Pacific Ocean, on 3 Nov 2026, 16:17 UTC. It was sailing from HOUSTON to BAHUDOPI. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

OBSERVATOR broadcasts MMSI 636015445 and is registered as IMO 9553244, with call sign D5AT8 . 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.

OBSERVATOR is classified as a cargo vessel registered under the LR 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 LR flag list at /flag/lr.

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.

OBSERVATOR is classed by LLOYD'S SHIPPING REGISTER, the classification society responsible for inspecting the vessel against safety, structural and operational rules. As a cargo, OBSERVATOR 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. OBSERVATOR has a gross tonnage of 32,987 GT.
