ATLAS 18 — Dredger · MMSI 668116359

ATLAS 18 has not broadcast an AIS position for 92 days. The most recent broadcast placed it in the South China Sea, on 7 Aug 2026, 00:53 UTC. It was sailing from VUNG TAU ANCH to BURGAS. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

ATLAS 18 broadcasts MMSI 668116359. 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.

ATLAS 18 is classified as a dredger vessel registered under the ST flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full dredger fleet at /vessel-type/military-special and full ST flag list at /flag/st.

MarineRadar shows the latest AIS broadcast from ATLAS 18 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 dredger, ATLAS 18 sits in the same design class as the other dredgers listed in the Similar Vessels section of the vessel page, or in the full dredger directory at /vessel-type/military-special.
