NAGA DUA — Tug · IMO 7351977

NAGA DUA has not broadcast an AIS position for 235 days. The most recent broadcast placed it in the South China Sea, on 19 Mar 2026, 00:59 UTC. It was sailing from SINGAPORE to PASIR GUDANG. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

NAGA DUA broadcasts MMSI 511101185 and is registered as IMO 7351977, with call sign T8A4459. 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.

NAGA DUA is classified as a tug vessel registered under the PW 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 PW flag list at /flag/pw.
