Frequently Asked Questions

Where is DELTA BIRU right now?+
DELTA BIRU has not broadcast an AIS position for 3 days. The most recent broadcast placed it in the Indian Ocean, on 5 Sep 2026, 12:25 UTC. It was sailing from MUARA BERAU ANCH to CLASS B. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

What type of ship is DELTA BIRU?+
DELTA BIRU is classified as a tug vessel registered under the ID 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 ID flag list at /flag/id.
