VOEA NGAHAU SILIVA — Law Enforce · IMO 4734180

VOEA NGAHAU SILIVA has not broadcast an AIS position for 19 days. The most recent broadcast placed it in the South Pacific Ocean, on 19 Oct 2026, 00:12 UTC. It was sailing from NUKU ALOFA to NUKU ALOFA. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

VOEA NGAHAU SILIVA broadcasts MMSI 570316000 and is registered as IMO 4734180, with call sign A3CR. 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.

VOEA NGAHAU SILIVA is classified as a law enforce vessel registered under the TO flag. The vessel-type classification is derived from the AIS Type field broadcast by the ship's transponder; full law enforce fleet at /vessel-type/military-special and full TO flag list at /flag/to.
