US Naval Blockade Fails to Halt Iranian Oil Exports as 'Shadow Fleet' Evades Detection

The US has imposed a naval blockade on shipping to and from Iranian ports in an effort to halt Iranian oil exports, but Tehran continues to export oil despite the restrictions. According to recent data, Iran is currently exporting around 260,000 barrels of oil per day, its lowest level in six years.

Tehran relies on a network of vessels and intermediaries, as well as tactics designed to conceal identities and manipulate navigational data, to circumvent the US sanctions. The 'shadow fleet' of Iranian oil tankers has been using false documents and records to pass through the blockade, with some ships even disabling their Automatic Identification System (AIS) transponders to evade detection.

Urriolagoitia Miner, a former U.S. military intelligence official, stated that Iranian oil 'doesn't get out through concealment alone; it is laundered at sea.' This involves transferring cargo from a sanctions-linked vessel to another ship with a clean record, effectively erasing its digital identity.

Analysts have identified over 30 instances of ship-to-ship transfers involving Iranian tankers, with most concentrated in three locations near the Iran-Iraq maritime border, Larak Island, and the Gulf of Jask. The operations involve multiple layers of intermediaries, including 'financial warlords and marine equipment suppliers in East Asia,' who reap substantial profits from facilitating the smuggling.
