HELENE MAERSK — Tanker · IMO 9389514

HELENE MAERSK has not broadcast an AIS position for 49 days. The most recent broadcast placed it in the North Sea, on 18 Sep 2026, 00:43 UTC. It was sailing from SHANGHAI to ANTWERP. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

HELENE MAERSK broadcasts MMSI 563096300 and is registered as IMO 9389514, with call sign 9V3469. 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.

HELENE MAERSK is classified as a tanker vessel registered under the SG 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 SG flag list at /flag/sg.
