GRETE MARIE — Tanker · IMO 9600384

GRETE MARIE has not broadcast an AIS position for 213 days. The most recent broadcast placed it in the North Sea, on 10 Apr 2026, 09:49 UTC. It was sailing from HAREN to HAREN. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

GRETE MARIE broadcasts MMSI 211525600 and is registered as IMO 9600384, with call sign DF6521. 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.

GRETE MARIE is classified as a tanker vessel registered under the DE 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 DE flag list at /flag/de.

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, GRETE MARIE 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.
