ROSTELLA — Tanker · IMO 9803247

ROSTELLA has not broadcast an AIS position for 19 days. The most recent broadcast placed it in the Coral Sea, on 18 Oct 2026, 14:05 UTC. It was sailing from GLADSTONE to PORTLAND OR. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

ROSTELLA broadcasts MMSI 563017700 and is registered as IMO 9803247, with call sign 9V5116. 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.

ROSTELLA is classified as a tanker vessel registered under the SG 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 SG flag list at /flag/sg.

MarineRadar shows the latest AIS broadcast from ROSTELLA 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.

As a tanker, ROSTELLA 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.
