Iran-Linked Oil Tankers Abruptly Change Course Amid Escalating US Blockade

Two US‑sanctioned tankers loaded with cooking fuel have begun making sharp U‑turns and zig‑zag maneuvers in the Gulf of Oman and the Arabian Sea, signaling a new twist in Washington’s tightening chokehold on Iranian maritime trade. The vessels are part of a larger flotilla hauling Iranian energy exports that now confront an increasingly aggressive US blockade aimed at curbing Tehran’s ability to move crude and refined products.

Key Developments
On Monday, satellite tracking showed the Suezmax‑class tanker “Persian Star” and the Aframax‑sized “Gulf Voyager” reversing course after entering the Strait of Hormuz, then looping back toward Iranian ports before heading south again. Both ships appear on the U.S. Treasury’s Specially Designated Nationals list, which bars them from calling at most international ports and accessing the global financial system. Analysts note the erratic routing is likely an attempt to evade heightened naval patrols and to confuse automated tracking algorithms used by sanction‑enforcement agencies. In the past 48 hours, at least six other Iranian‑linked carriers have exhibited similar deviation patterns, suggesting a coordinated effort among operators to keep cargoes moving despite the blockade.

Industry Analysis
Maritime security experts say the U.S. blockade has evolved from a simple denial‑of‑entry policy to a dynamic, intelligence‑driven campaign that leverages real‑time AIS data, satellite imagery, and partner navies in the Gulf. The sudden course changes raise operational costs for shipowners, who now face higher fuel consumption, increased crew fatigue, and potential demurrage charges. Moreover, the tactic of “zig‑
