CAI YUN — Tanker · IMO 9437983

CAI YUN has not broadcast an AIS position for 98 days. The most recent broadcast placed it in the Baltic Sea, on 3 Aug 2026, 03:34 UTC. It was sailing from MERSA EL HAMRA to MERSA EL HAMRA ANCH. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

CAI YUN broadcasts MMSI 667001407 and is registered as IMO 9437983, with call sign 9LU2210. 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.

CAI YUN is classified as a tanker vessel registered under the SL 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 SL flag list at /flag/sl.

MarineRadar shows the latest AIS broadcast from CAI YUN 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, CAI YUN 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.
