Shipowner advisory: do not pay pgsa.ir

The Persian Gulf Strait Authority operating from info@pgsa.ir is an interface to the Islamic Revolutionary Guard Corps (IRGC), a U.S.-designated FTO. The U.S. Treasury has indicated it will sanction entities that pay Iran for transit through the Strait of Hormuz.

  • Cryptocurrency payment requests are always fraudulent — no legitimate state authority demands USDT.
  • Verify any communication claiming to be PGSA against the operator's flag-state and your P&I club before responding.
  • Coordinate transit with UKMTO and the U.S.-led Project Freedom umbrella where applicable.

Theater of operations

Strait of Hormuz at a glance — chokepoint geography, IMO Traffic Separation Scheme, the U.S.-led Project Freedom outbound corridor, and known IRGC threat positions on Iranian-controlled islands. Illustrative; not a navigational chart.

Strait of Hormuz operational map Iran's southern coast above, with Bandar Abbas and Iranian-controlled islands (Larak, Abu Musa, Greater and Lesser Tunb) bearing IRGC missile and radar positions. The Musandam Peninsula of Oman juts north from the bottom, forming the southern wall of the chokepoint, with UAE coast to the southwest. The Persian Gulf opens west, the Gulf of Oman east. Two TSS lanes run through the strait: inbound (closer to Iran) and outbound (closer to Oman). The Project Freedom corridor follows the outbound lane through Omani waters, escorted by U.S. and partner naval forces. A stippled amber zone over the strait and its eastern approaches marks an area of active GPS spoofing and AIS anomalies, where transmitted vessel positions are frequently jammed, falsified, or absent.

Map is illustrative and stylized — coastlines abstracted, distances not to scale. For navigation, use authoritative charts (UKHO ADMIRALTY, NGA, or flag-state equivalent). For real-time threat positioning, refer to UKMTO advisories and your P&I circular. The GPS-spoofing / AIS-anomaly zone reflects advisories current as of June 2026; electronic interference is dynamic and its extent shifts — this is precisely why we do not plot live vessel positions, which are unreliable here.
