STB 38 — Cargo · IMO 8518675

STB 38 has not broadcast an AIS position for 37 days. The most recent broadcast placed it in the Indian Ocean, on 3 Oct 2026, 18:52 UTC. It was sailing from GRESIK to KOLAKA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

STB 38 broadcasts MMSI 525300154 and is registered as IMO 8518675, with call sign PKPR. 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.

STB 38 is classified as a cargo vessel registered under the ID 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 ID flag list at /flag/id.

MarineRadar shows the latest AIS broadcast from STB 38 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 cargo, STB 38 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.
