SDTR DORIS — Cargo · IMO 9877860

SDTR DORIS has not broadcast an AIS position for 222 days. The most recent broadcast placed it in the East China Sea, on 29 Mar 2026, 18:20 UTC. It was sailing from GERALDTON to HUANGHUA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SDTR DORIS broadcasts MMSI 538009572 and is registered as IMO 9877860, with call sign V7A4908. 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.

SDTR DORIS is classified as a cargo vessel registered under the MH flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full cargo fleet at /vessel-type/cargo and full MH flag list at /flag/mh.

MarineRadar shows the latest AIS broadcast from SDTR DORIS above, with current position, course, speed, and navigation status.

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 cargo, SDTR DORIS sits in the same design class as the other cargos listed in the Similar Vessels section of the vessel page, or in the full cargo directory at /vessel-type/cargo.
