RUI WEI — Tanker · IMO 9153824

RUI WEI has not broadcast an AIS position for 10 days. The most recent broadcast placed it in the North Pacific Ocean, on 27 Oct 2026, 16:36 UTC. It was sailing from SINGAPORE to PUERTO QUETZAL. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

RUI WEI broadcasts MMSI 668116337 and is registered as IMO 9153824, with call sign S9A3137. 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.

RUI WEI is classified as a tanker vessel registered under the ST 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 ST flag list at /flag/st.

MarineRadar shows the latest AIS broadcast from RUI WEI 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, RUI WEI 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.
