Since April 13, the U.S. has imposed a maritime embargo on Iranian vessels, yet 34 tankers linked to Tehran have slipped past the blockade, according to cargo‑tracking firm Vortexa. Trump hails the move as a “tremendous success,” while U.S. Central Command reports 28 ships turned back and one container seized in the Gulf of Oman at port now again today.

Among those that escaped, the supertanker Dorena navigated past the blockade with its transponder off and later joined a ship‑to‑ship transfer off Malaysia. Six vessels carried a combined 10.7 million barrels of Iranian crude, worth roughly $910 million at a $10 discount to Brent. The U.S. estimates this revenue would have been blocked for the Iranian oil market today and investors watching.

Iran has kept the Strait of Hormuz under tight control, insisting ships must follow a state‑approved route and receive Tehran’s permission. After Friday’s attempt by 30 vessels, Iranian troops fired on a French container and an Indian tanker, prompting a drop in traffic. Shipowners label the situation a “double blockade,” as U.S. Navy actions and Iranian restrictions converge today for.
