SURABAYA — Other · IMO 9351907

SURABAYA has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the Java Sea, on 5 Nov 2026, 02:05 UTC. It was sailing from JAKARTA to Surabaya Indonesia. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SURABAYA broadcasts MMSI 525935190 and is registered as IMO 9351907, with call sign PLEX. 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.

SURABAYA is a maritime vessel registered under the ID flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full ID flag list at /flag/id.

MarineRadar shows the latest AIS broadcast from SURABAYA above, with current position, course, speed, and navigation status.

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.

The vessel's design class is inferred from its dimensions, gross tonnage and dead weight, all of which are listed in the Identity and Specifications panels on the vessel page.
