DING HENG 23 — Tanker · IMO 9841421

DING HENG 23 has not broadcast an AIS position for 182 days. The most recent broadcast placed it in the Mediterranean Sea, on 11 May 2026, 09:53 UTC. It was sailing from VLAARDINGEN to HUELVA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

DING HENG 23 broadcasts MMSI 477931300 and is registered as IMO 9841421, with call sign VRVT2. 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.

DING HENG 23 is classified as a tanker vessel registered under the HK 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 HK flag list at /flag/hk.

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, DING HENG 23 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.
