BUANA EXPRESS 25 — Tug · MMSI 525500746

BUANA EXPRESS 25 has not broadcast an AIS position for 5 days. The most recent broadcast placed it in the Strait of Malacca, on 1 Nov 2026, 07:36 UTC. It was sailing from TANJUNG MERPATI to BELAWAN. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

BUANA EXPRESS 25 broadcasts MMSI 525500746, with call sign YDB3168. 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.

BUANA EXPRESS 25 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.

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.
