KMSC NO502 — Tug · MMSI 416005912

KMSC NO502 has not broadcast an AIS position for 30 days. The most recent broadcast placed it in the South China Sea, on 8 Oct 2026, 08:29 UTC. It was sailing from KAOHSIUNG to KAOHSIUNG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

KMSC NO502 broadcasts MMSI 416005912, with call sign BR4198 . 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.

KMSC NO502 is classified as a tug vessel registered under the TW flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full tug fleet at /vessel-type/tug-pilot-vessel and full TW flag list at /flag/tw.

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.
