Tanker Tracking

Since the onset of Operation Epic Fury, UANI has monitored a significant volume of Iranian oil at sea. Illicit Iranian oil sales are a major source of funding for the Islamic Revolutionary Guard Corps (IRGC), which is currently conducting military and terrorist operations targeting the U.S., Israel, Arab states in the Persian Gulf, and international shipping. In the weeks leading up to the conflict, Tehran sharply increased crude loadings and offshore stockpiling to cushion the impact of war on its oil trade. Amid ongoing hostilities, the Iranian regime’s Ghost Fleet continues to operate actively — loading cargo, transiting the Strait of Hormuz, and heading east toward its primary buyer, China. UANI’s regular shipping update will continue to monitor and report on the illicit maritime movements of the Iranian regime’s ghost fleet throughout the conflict.

Shadow Fleet, Shifting Risks: How Sanctions and Maritime Evasion Threaten Global Oil Spill Liability Regimes

Recent developments from Washington, London, and Panama signal a tightening of global scrutiny, but also highlight new links between sanctions enforcement and environmental protection.

On April 16, 2025, the U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) issued a significant update to its maritime sanctions advisory aimed at helping global shipping and trade stakeholders detect and prevent the evasion of U.S. sanctions on Iranian oil.

​Updated: May 12, 2026

As the maritime industry gathered for Singapore Maritime Week 2025, one of the industry's most important annual events, participants grappled with a central concern: the intensifying threat posed by the Iranian-backed ghost fleet. Against a backdrop of rising geopolitical tension, sanctions enforcement, and growing environmental risk, the week's discussions reflected the urgency of safeguarding the integrity of global shipping.

UANI’s Masters of the Ghost Armada: The Captains Steering Iran’s Illicit Oil Trade is a groundbreaking tool that identifies and tracks captains and chief officers serving on vessels sanctioned for illegally transporting Iranian oil. These maritime officers are not merely unsuspecting bystanders in this illicit trade.
