SAO LUIS — Tug · IMO 8716239

SAO LUIS has not broadcast an AIS position for 215 days. The most recent broadcast placed it in the South Atlantic Ocean, on 6 Apr 2026, 19:38 UTC. It was sailing from SAO FRANCISCO DO SUL to NAVEGANTES. Vessels stop appearing on terrestrial AIS when they move beyond receiver range, so a gap does not necessarily mean the vessel is inactive.

SAO LUIS broadcasts MMSI 710015190 and is registered as IMO 8716239, with call sign PPSC . 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.

SAO LUIS is classified as a tug vessel registered under the BR 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 BR flag list at /flag/br.

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.
