MPA GUARDIAN — Port Tender · MMSI 563080160

MPA GUARDIAN has not broadcast an AIS position for 46 days. The most recent broadcast placed it in the South China Sea, on 23 Sep 2026, 05:04 UTC. It was sailing from SINGAPORE to SINGAPORE. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

MPA GUARDIAN broadcasts MMSI 563080160, with call sign 9V7882. 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.

MPA GUARDIAN is classified as a port tender vessel registered under the SG flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder and full SG flag list at /flag/sg.

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 port tender, MPA GUARDIAN sits in the same design class as the other port tenders listed in the Similar Vessels section of the vessel page.
